What Is a Home Appraisal and Why Are They Needed? 2026 Ontario Guide

Home appraisal in Ontario 2026 guide

A home appraisal is not the price you agreed to pay, not the number on your tax bill, and not what a real estate agent thinks your home could list for. It is one specific thing: an independent, written opinion of market value on a specific date, prepared by a designated appraiser working to Canadian standards, for a named client and a named use.

The 2023 version of this article got the broad idea right — appraisals matter for mortgages, sales, and refinancing — but it left out almost everything an Ontario owner actually needs in 2026: what it costs in the GTA, who the client legally is (often not you), why your MPAC assessment is still based on January 1, 2016 values, how rental income changes the valuation, and what your real options are when the number comes in low. It also said insurers use an appraised value to set coverage, which mixes up market value with rebuilding cost. This guide corrects that and replaces it.

This is general information about appraisal and mortgage practice in Ontario, not valuation, mortgage, or legal advice for a specific property.

TL;DR

  • Definition: an appraisal is an independent opinion of market value at a specific date, prepared under the Canadian Uniform Standards of Professional Appraisal Practice (CUSPAP) by an Appraisal Institute of Canada (AIC) designated appraiser — CRA for residential properties up to four units, AACI for all property types including commercial and larger multi-family.
  • Cost in 2026: a standard residential appraisal in Toronto and the GTA typically costs about $400 to $700. Complex or Toronto-core properties run about $700 to $1,500 or more, and divorce, retrospective, or court-ready reports run about $900 to $2,500 or more. Rush, large, and rural files cost more. Get the fee, the effective date, and the intended use in writing.
  • Who controls it: for a mortgage, the lender or mortgage broker orders the appraisal, usually through an appraisal management company. The borrower usually pays the fee, but the ordering party is the appraiser’s client — the report is addressed to that client, and the appraiser needs the client’s permission to release it to you.
  • The lender’s rule: lenders finance against the lower of the purchase price and the appraised value. If you agree to $700,000 and the appraisal is $650,000, a lender advancing 80% lends $520,000, not $560,000 — you need $40,000 more cash to close at the same price.
  • MPAC is not an appraisal for lending: your 2026 Ontario property taxes are still based on MPAC’s fully phased-in January 1, 2016 value. The province-wide reassessment remains postponed, so an MPAC number well below today’s market price is normal, not an error.
  • Timing: the appraisal step inside a mortgage file commonly takes about 3 to 5 business days, and about a week from scheduling to report is a realistic planning figure. Lenders typically accept an appraisal for about 60 to 90 days, depending on the lender and the market.
  • If it comes in low: check the report for factual errors, ask the lender for a reconsideration of value with stronger comparable sales, renegotiate or split the gap, cover the gap in cash, or — where the contract and your financing allow it — change lenders. None of these is guaranteed to change the number.

What a home appraisal actually is

An appraisal answers one question: what is this property’s market value on this date, for this use, based on evidence a designated appraiser can defend? Market value means the most probable price in an open market between willing, informed parties — not the highest price a particular buyer offered in a bidding war, and not a forced-sale price.

Three parts of that definition matter in practice.

  • A specific date. Every appraisal has an effective date. A divorce, estate, or tax appraisal may value the property as of a past date (a retrospective appraisal) using sales from around that date, not today’s market.
  • A named client and intended use. A report prepared for a lender for mortgage financing is not automatically usable for a court, the Canada Revenue Agency, or a different lender. If you need the report for more than one use, say so before it is ordered — changing the client or use afterwards usually means a new assignment.
  • An opinion, supported by evidence. Two competent appraisers can land on somewhat different numbers for the same property. What makes a report credible is the comparable sales, adjustments, and reasoning shown inside it — which is why you should always ask for the full report, not just the final figure.

An appraisal is also not a guarantee. It does not promise the property will sell for that amount, and it does not certify the property’s condition. It is a valuation opinion at a point in time.

Who is qualified to appraise in Canada

In Canada, the designations lenders rely on come from the Appraisal Institute of Canada (AIC). There are two core designations, and the scope difference matters:

  • CRA — Canadian Residential Appraiser. Qualified for residential properties containing not more than four self-contained family housing units, and individual undeveloped residential lots. A CRA who signs a report beyond that scope must have it co-signed by an AACI.
  • AACI — Accredited Appraiser Canadian Institute. The broader designation, covering all property types where the appraiser has demonstrated competence — commercial, larger multi-family, complex residential, and other assignments.

Both designations require university-level coursework, supervised practical experience, adherence to CUSPAP, continuing professional development, and professional liability insurance. A second body, the Canadian National Association of Real Estate Appraisers (CNAREA, DAR designation), also credentials residential appraisers, but acceptance varies by lender — some lenders will not accept a CNAREA report, so for a mortgage file the lender’s approved list controls.

What an appraiser is not: a real estate agent giving a listing opinion, a home inspector assessing condition, or MPAC assessing your property for taxes. Each of those is a different job, covered in the comparison section below.

For a standard house, townhome, or condo mortgage in Ontario, a CRA is fully qualified. For a building with more than four units, a mixed-use property, or a commercial file, expect an AACI.

When an appraisal is needed — and when it is not

Mortgage purchase

On a conventional mortgage — generally, a purchase with 20% or more down — the lender commonly orders an appraisal to confirm the property supports the loan. The lender is protecting its security: if the borrower defaults, the property is what the lender recovers against.

On an insured mortgage (less than 20% down), the picture is different. The mortgage insurer reviews value, often with automated valuation tools, and in many cases no full in-person appraisal is ordered at all. If the insurer does require one, the insurer normally arranges and pays for it. Do not assume every purchase involves a $400 to $700 appraisal bill — ask your broker which route your file is on.

Refinancing and home equity borrowing

A refinance, an equity take-out, or a new or increased home equity line of credit opens a new valuation. The lender will lend against current appraised value, not the value from when you bought. In a softer market that new number can come back lower than the one your current borrowing was set on, which reduces how much you can refinance or borrow — even though you have not borrowed a dollar more.

Selling and buying decisions

A seller does not need an appraisal to list — an agent’s comparative market analysis is the usual pricing tool. A pre-listing appraisal can still help where comparable sales are thin, the property is unusual, or the parties do not trust the same pricing evidence. A buyer who is paying cash, waiving financing conditions, or buying a unique property may also order one for their own decision-making.

Divorce, estate, and other legal uses

Separating spouses often need one independent, lender-accepted number to settle a buyout, instead of two competing agent opinions. A joint appraisal — one appraiser, agreed in writing, with both parties receiving the report at the same time, on an agreed effective date — can save legal costs and months of dispute. Estates, probate, and capacity or litigation files similarly need a defensible value at a specific date, which is what a retrospective, court-ready report provides — and why those reports cost more.

Tax events

Some tax filings turn on fair market value at a specific date — for example, a change in use of a property, a deemed disposition, or a non-arm’s-length transfer. An appraisal dated to that event is the evidence that supports the number filed. The rules are fact-specific, so get tax advice for the filing itself; the appraisal supplies the value, not the tax treatment.

What an appraisal is not required for

Renting out a long-term unit, setting a nightly Airbnb rate, or challenging your property taxes do not start with a mortgage appraisal. Pricing a rental uses market rent evidence (see our guide to increasing the value of a rental property), and a tax assessment challenge uses MPAC’s own process, explained below. Ordering the wrong kind of valuation wastes the fee.

The three approaches to value

Appraisers do not apply every method mechanically. Under CUSPAP they use and weigh the approaches that are credible for that property and assignment, and they must give reasons if they exclude a relevant approach.

1. Direct comparison approach

The appraiser compares your property with recent sales of similar properties and adjusts for meaningful differences — location, living area, lot, condition, parking, renovations, and unit features. This is the main approach for houses, townhomes, and condo units where good comparable sales exist, and it is the approach most mortgage reports rest on.

Its weakness is also obvious: for a unique, custom, or rarely traded property, there may be few truly comparable sales, and the adjustments get larger and less certain.

2. Cost approach

Land value, plus the current cost to build a similar improvement, minus depreciation and obsolescence. A buyer, in theory, will not pay more for a property than it would cost to buy comparable land and build something similar. This approach is most useful for newer construction, special-purpose properties, and properties that do not trade often. Insurers think in a related but different number — replacement or rebuilding cost — which is not market value, as explained below.

3. Income approach

For a property bought for the income it produces, the appraiser analyses sustainable rent, vacancy, operating expenses, and a market capitalization rate (or a discounted cash flow) to convert net operating income into value. This is the approach that matters for apartment buildings, other multi-residential property, and commercial property — and, in a supporting role, for a house or small plex bought purely as a rental.

A simple illustration of the arithmetic (labelled arithmetic, not a market forecast): if a small rental produces $18,000 a year in net operating income after vacancy and operating expenses, and comparable sales support a 4.5% capitalization rate, the income indication is $18,000 divided by 0.045 — $400,000. Change the income or the cap rate and the indicated value moves with it, which is why appraisers test the rent roll against market rents instead of accepting an owner’s figures at face value.

For most Toronto condo and house mortgage appraisals, expect direct comparison to carry the weight, with the other approaches used as a check where they are relevant. For a larger rental building, expect the income approach to carry at least as much weight as the sales evidence. Our flipping versus rental property guide works through how investors use these numbers when they choose a strategy.

Appraisal vs. inspection, CMA, MPAC, and insurance value

Five different numbers get called “the value” in a real estate file. Confusing them is expensive.

  • Appraisal — market value for a named use. Independent, designated, written to CUSPAP, with comparable sales and adjustments. The only one on this list a mortgage lender orders to support a loan amount.
  • Home inspection — condition, not value. An inspector evaluates accessible structure and systems — roof, heating, plumbing, electrical, foundation — and identifies defects and repairs. An appraiser notes condition as it affects value and may flag obvious issues, but an appraisal is not an inspection and does not replace one. Budget separately: Ontario closing guides commonly put a home inspection at about $400 to $600.
  • Comparative market analysis (CMA) — an agent’s pricing opinion. Useful for setting a listing price and negotiating strategy. It is informal, the agent is not independent of the transaction, and a lender will not lend against it. A CMA can be free; that does not make it an appraisal.
  • MPAC assessment — value for distributing property taxes. MPAC mass-appraises every property in Ontario. For the 2026 tax year that value is still the fully phased-in January 1, 2016 value, because the province postponed the 2020 reassessment and has kept it postponed. An MPAC value far below today’s sale price is therefore expected. If you think your assessment is wrong, the test is not “below today’s market” — it is whether, on that same January 1, 2016 basis, your property is assessed too high compared with similar properties. The first step is a free Request for Reconsideration (RfR) with MPAC; if you are still unsatisfied, residential owners can then appeal to the Assessment Review Board (ARB), following the deadline on the notice. See our Toronto vacant home tax guide for the separate declaration every Toronto owner must also file.
  • Insurance value — cost to rebuild, not price to sell. Home insurance is set on the cost of repairing or rebuilding the structure (and on the policy’s terms), not on the market value of the land plus building. Land does not burn down. A downtown condo can have a market value well above its rebuilding cost; a house on cheap land can cost more to rebuild than it would sell for. The 2023 version of this article said insurers use the appraised value to set the coverage amount and premium — that is not the right way to think about it, and using a market appraisal as your insurance figure can leave you over- or under-insured. For short-term rental coverage specifically, see our guide to short-term rental insurance in Ontario.

The process, step by step

  1. The order. For a mortgage, the lender or broker places the order, often through an appraisal management company that assigns an approved local appraiser. You do not pick the appraiser on a lender file — independence is the point.
  2. The fee and the terms. The assignment names the client, the intended use, the effective date, and the fee. On a borrower-paid file, expect to pay before or at the inspection. Confirm whether the quote covers a standard residential form report or a fuller narrative report — they are priced differently.
  3. The inspection visit. The appraiser visits, measures, photographs, and notes condition, layout, finishes, mechanicals, parking, and any obvious defects or unpermitted-looking changes. Provide access to every room, the mechanical area, the garage, and any secondary suite. For a condo, access to the unit is what matters most; common elements are usually reviewed from records and a walk-through.
  4. The analysis. Back at the office, the appraiser researches recent comparable sales, makes adjustments, considers any other relevant approach, and reconciles the evidence into one value conclusion. This desk work is most of the assignment — the visit is the visible part, not the whole job.
  5. The report to the client. The report goes to the client who ordered it. On a mortgage file that is the lender or broker — ask them for a copy, and understand the appraiser cannot simply hand it to you without the client’s permission. Read the full report: the comparable sales chosen, the adjustments, and any assumptions or limiting conditions.
  6. Lender review. The lender may accept the report, ask the appraiser for clarification, or require more information. Mortgage approval remains the lender’s decision — a clean appraisal does not by itself approve your mortgage.

Cost, timing, and how long the report lasts

Cost

  • Standard Toronto/GTA residential appraisal: about $400 to $700.
  • Complex or Toronto-core properties: about $700 to $1,500 or more.
  • Divorce, retrospective, or court-ready reports at family-law-focused firms: about $900 to $2,500 or more.
  • Simpler lender-ordered files in some closing-cost guides are quoted at about $300 to $500 — the fee depends on the property, the report type, and the turnaround, so treat any single figure as a quote to confirm, not a fixed price.

Who pays follows who orders and why. On a purchase or refinance, the borrower usually pays, even though the lender is the client. On a joint divorce appraisal, splitting the fee equally is common. On an insured mortgage where the insurer requires the appraisal, the insurer normally pays. Some lenders cover or credit the appraisal fee as part of an offer — ask before you assume it is your cost.

Timing

Within a mortgage file, the appraisal and property review step typically takes about 3 to 5 business days, and planning on about a week from scheduling to a delivered report is realistic for a standard home. Full mortgage approval on an accepted offer commonly takes 3 to 10 business days in total when documents are complete — the appraisal is one step inside that window, and a delayed inspection visit or a hard-to-value property can stretch it. Rush service exists on many files, at a higher fee.

How long it lasts

An appraisal speaks as of its effective date. Lenders typically accept one for about 60 to 90 days, depending on the lender and how fast the market is moving; in a shifting market a lender may ask for an update or a new report sooner. A pre-approval, by comparison, commonly holds a rate for 90 to 120 days — do not confuse the rate hold with the life of the appraisal. If your closing slips past the window your lender allows, budget for the possibility of a second appraisal.

What actually moves the number

  • Comparable sales. Recent, nearby, truly similar sales carry the most weight. In a condo building, a recent sale of the same layout in the same building is stronger evidence than a newer building across the street.
  • Location within the market. Street, neighbourhood, transit, schools, and nuisances are priced through the comparable sales — an appraiser does not add a separate “good neighbourhood” bonus on top of them.
  • Size, layout, and usable space. Measured living area, bedroom and bathroom count, functional layout, parking, locker, and outdoor space. Unfinished or unpermitted space may be given little or no value until it is legal and finished.
  • Condition and effective age. A renovated kitchen helps in two ways: the comparable adjustments reflect it, and the property’s effective age drops. Deferred maintenance works the other way — an appraiser will reflect the cost to cure obvious items. Our maintenance and repairs guide sets out the repair duties and trade costs behind that condition assessment.
  • Legal and planning status. Zoning, permits, a legal secondary suite versus an informal one, condo status and reserve fund health, and — for a Toronto short-term rental — whether the unit can legally be operated at all. An illegal use does not get valued as if it were legal.
  • Market conditions on the effective date. The same property appraised in a rising month and a falling month can produce different supported numbers, because the comparable sales themselves have moved.

What does not move the number: what you paid for the property years ago, what you spent on a renovation dollar-for-dollar (cost does not equal value), what a neighbour’s home was listed for without selling, and your MPAC assessment.

Appraisals for rental and Airbnb properties

Owners meet appraisals at three points in a rental’s life.

Buying a rental

If you are financing the purchase, expect the lender’s appraisal as above. If the property is a duplex, triplex, or fourplex, a CRA can complete it, and the income evidence will usually support the comparison evidence. Above four units, expect an AACI and an income-led report. Before you buy a Toronto property planning to run it as an Airbnb, read our guide to buying a property for Airbnb in Toronto — the principal-residence rule decides whether short-term rental use is legally available at all, and an appraiser will not value an illegal use as income.

Refinancing a rental you already own

This is where the income approach meets your rent roll. Bring the leases, a current rent roll, 12 months of expenses, and records of capital work. For a rent-controlled Ontario unit, lawful rent is what the file supports — the 2026 rent increase guideline is 2.1% for units covered by the guideline, and an appraiser using market rent where the lawful rent is materially lower should explain that choice in the report. If the new appraisal comes in low, the refinance amount falls with it, as in the worked example below. Our Ontario Airbnb tax rules guide covers the tax side that sits alongside any refinance or change in use.

Toronto short-term rentals: value the legal use

A Toronto home’s Airbnb income exists only inside the city’s rules: the home must be your principal residence, registration is $390 per year, an entire unit is capped at 180 nights per calendar year, stays are under 28 consecutive nights, and guests pay the 6% Municipal Accommodation Tax (in place since August 1, 2026) plus 13% HST where it applies. Do not present — and do not accept — a valuation that capitalises year-round, whole-home Airbnb income from a property that cannot legally earn it. A realistic Toronto model uses lawful nights and rates, which is the same discipline behind our Toronto condo Airbnb income estimate.

Management costs belong in that same realistic model. Long-term rental management in Ontario commonly runs about 8% to 12% of rent, plus a placement fee of about 50% to 100% of one month’s rent. Home Again’s full-service short-term rental management is 15% of booking revenue — state the basis whenever you compare a percentage, because a fee charged on net revenue and a fee charged on gross revenue are not the same number in practice. See our Toronto Airbnb management page for what that service covers.

How to prepare — without trying to influence the result

You cannot — and should not try to — talk an appraiser into a number. Pressure undermines the report’s credibility with the very lender or court you need to persuade. What you can do is make sure the evidence in front of the appraiser is complete and accurate:

  • List renovations and repairs with dates, scope, permits, and costs, with receipts where you have them. Distinguish a full permitted renovation from cosmetic work.
  • For a rental, provide the leases, rent roll, and expense records together — and, in a joint or disputed file, send the same package to the other party at the same time.
  • For a condo, have the status information you hold available, including any known special assessments.
  • Note anything the appraiser cannot see on a walk-through: a recently replaced furnace or roof, a legal secondary suite’s permits, or a known defect you are disclosing.
  • Make access easy and the home tidy. Tidy is fine; staging a renovation you have not done is not preparation, it is misrepresentation.
  • Be present or have a representative present if you wish, answer factual questions honestly, and then let the appraiser work.

After the report arrives, check it for factual errors — wrong living area, a missed bathroom, a comparable sale that is not comparable, a renovation omitted. A factual correction supported by documents is a legitimate request. A demand for a higher number with no new evidence is not.

If the appraisal comes in low

First, understand the mechanics. The lender finances against the lower of the purchase price and the appraised value, at your loan-to-value ratio. The shortfall does not shrink your mortgage by the full gap — it shrinks it by the gap multiplied by that ratio — but the cash you must bring rises by exactly that amount, as the worked example shows. On a refinance, there is no seller to negotiate with: a low appraisal simply reduces the mortgage the lender will advance, and the refinance may no longer cover what it was meant to pay out.

Your options, in the order most files try them:

  1. Review the report carefully. Look for factual errors, overlooked recent comparable sales, and comparables that are poor matches — older, inferior buildings or sales that needed larger adjustments. This review is what any later step stands on.
  2. Ask for a reconsideration of value, through the lender. You do not appeal directly to the appraiser on a lender file. The request goes through the lender, with documented support — usually stronger comparable sales. The appraiser may revise the value or stand by it. Both outcomes are common; a well-documented request is worth making, and it is not a guarantee.
  3. Renegotiate the price. The seller can lower the price to the appraised value, or both sides can split the gap. A seller who refuses should weigh that the next financed buyer will likely face the same valuation evidence.
  4. Cover the gap in cash. Bring the additional funds and close at the agreed price. This works when the gap is small relative to your reserves — and is the wrong move if it empties the reserve you need after closing.
  5. Try another lender. A different lender orders its own appraisal, which may land differently, and some lenders weight a file differently. This takes time — plan on roughly 10 to 20 business days to rebuild a file before a firm closing — may cost a second appraisal fee, and does not guarantee a higher value.
  6. Use the contract’s conditions, if you have them. Whether you can walk away, and what happens to the deposit, depends on the exact wording of your agreement — a financing or appraisal condition, where one exists and has not been waived, is what protects you. Get legal advice before treating a low appraisal as an exit.

What not to do: order a string of private appraisals hoping one will be higher and expect a lender to accept the best one — the lender’s own ordered report governs its loan — or pressure the assigned appraiser directly, which can taint the file.

Worked example: the appraisal gap in dollars

Labelled arithmetic, using round numbers, to show the mechanism — not a prediction for any property.

  • Agreed purchase price: $700,000, with 20% down.
  • Planned cash down payment: $140,000. Planned mortgage: $560,000 (80% of the price).
  • Appraisal comes in at: $650,000.
  • Lender’s mortgage: 80% of the lower number — 80% of $650,000 = $520,000.
  • Cash needed to close at the same price: $700,000 minus $520,000 = $180,000.
  • Extra cash caused by the low appraisal: $180,000 minus $140,000 = $40,000.

The same $50,000 gap resolves differently if the seller splits it: at a revised price of $675,000, the lender advances 80% of $650,000 (still the lower number) — $520,000 — and the buyer’s cash is $155,000, or $15,000 more than planned. Notice the pattern: until the price falls all the way to the appraised value, every dollar of price reduction helps the buyer’s cash position, but the lender’s number stays anchored to the appraisal.

For context on where Toronto prices sit while this math plays out, TRREB reported a GTA average selling price of $1,006,409 in September 2026, down 5.1% year over year, with a Toronto condo average of $640,248. In a falling or flat market, appraisals anchored to recent comparable sales are less likely to chase a price set on older expectations — which is exactly when the gap conversation above happens.

The Toronto market context in fall 2026

An appraisal is a backward-looking evidence exercise in a forward-moving market, and fall 2026 is a market where that lag is visible. Prices are modestly lower than a year ago on the TRREB figures above, the Bank of Canada policy rate has been held at 2.25%, and Toronto asking rents have softened — Rentals.ca and Urbanation put the September 2026 Toronto average asking rent at $2,554, with a one-bedroom at $2,228. None of those headline numbers appraises your property. What they do is explain the comparable sales an appraiser will find: recent, slightly softer sales, rather than the peak-era sales a seller may still be anchored to.

Two practical consequences follow. First, on a purchase, keep a financing condition and a cash buffer for the gap until the appraisal is back — the worked example is not a rare case in a softening market. Second, on a refinance or equity line increase, run your own conservative value first, using recent comparable sales rather than an asking price or your 2016-based MPAC figure, so a lower appraisal is a disappointment rather than a failed plan. Our guide to a landlord’s responsibilities in Ontario covers the ongoing duties that keep a rental’s condition — and therefore its appraised condition adjustments — from drifting the wrong way between valuations.

How a property manager helps

A property manager cannot influence an appraiser, and any manager who promises a valuation outcome is promising something no one can deliver. What a manager can do is keep the evidence clean:

  • Maintain the rent roll, leases, and expense records an income-approach appraisal needs, instead of reconstructing them under a refinancing deadline.
  • Keep dated records and receipts for capital work and renovations, so completed work is documented rather than asserted at the inspection.
  • Coordinate access for the appraisal visit during a tenancy or between guests, without breaching the tenant’s entry rights or a guest’s booking.
  • Keep the property’s condition — the thing adjustments are made for — from deteriorating between valuations, through regular turnover inspections and planned maintenance.

Home Again manages short-term and long-term rentals across Toronto and the GTA. If a purchase, refinance, or buyout valuation is part of a bigger rental decision, start with the numbers on our income estimate page and talk to us about what management would cost on the same property — the valuation tells you what the property is worth; the operating numbers tell you what it is worth to hold.

Frequently asked questions

What is a home appraisal in Ontario?

It is an independent, written opinion of a property’s market value on a specific date, prepared by a designated appraiser (AIC CRA or AACI) to Canadian Uniform Standards of Professional Appraisal Practice, for a named client and use — most often a lender deciding a mortgage amount.

How much does a home appraisal cost in Toronto in 2026?

A standard residential appraisal in Toronto and the GTA typically costs about $400 to $700. Complex or Toronto-core properties run about $700 to $1,500 or more, and divorce, retrospective, or court-ready reports about $900 to $2,500 or more. Confirm the fee, effective date, and intended use in writing before the assignment starts.

Who pays for the appraisal, and who gets the report?

On a purchase or refinance the borrower usually pays, but the lender or broker who ordered it is the appraiser’s client, and the report is delivered to that client. Ask the lender or broker for a copy — the appraiser needs the client’s permission to release it to you. On an insured mortgage, if the insurer requires an appraisal, the insurer normally arranges and pays for it.

Is an appraisal the same as my MPAC assessment?

No. MPAC assesses every Ontario property for property taxes, and for the 2026 tax year that value is still based on January 1, 2016 — the province-wide reassessment remains postponed. A lender’s appraisal values your property in today’s market. A large gap between the two numbers is normal, and a tax challenge uses MPAC’s free Request for Reconsideration process, not a mortgage appraisal.

How long does an appraisal take, and how long is it valid?

The appraisal step in a mortgage file commonly takes about 3 to 5 business days, and about a week from scheduling to report is a realistic plan for a standard home. Lenders typically accept an appraisal for about 60 to 90 days, depending on the lender and market conditions, after which an update or a new appraisal may be required.

What can I do if the appraisal comes in low?

Check the report for factual errors and weak comparable sales, ask the lender for a reconsideration of value supported by stronger comparables, renegotiate the price or split the gap with the seller, cover the gap in cash, or try another lender whose own appraisal may differ. None is guaranteed, and whether you can walk away depends on the conditions in your agreement — get legal advice before relying on that.
