Home Appraisal in Canada: What to Expect, Costs & How to Challenge

Updated

The home appraisal is a critical step in the mortgage process that many buyers don’t fully understand. The lender orders an appraisal to confirm the property is worth what you’re paying — and if the appraisal comes in low, it can derail your purchase. Here’s how the appraisal works, what to expect, and what to do if it doesn’t go in your favour.

Why lenders require appraisals

The lender is using the property as collateral for your mortgage. They need to confirm that if you default, they can sell the property and recover their money. The appraisal protects the lender, not you — but it indirectly protects you from overpaying.

PurposeDetails
Confirm market valueEnsures the property is worth the purchase price
Calculate loan-to-value (LTV)Determines how much the lender will finance
Identify major issuesObvious structural defects, environmental problems
Satisfy insurance requirementsCMHC/insurer needs value confirmation for insured mortgages

You need both. The appraisal ensures the price is fair. The inspection ensures the property is sound.

What to do if the appraisal comes in low

A low appraisal means the property was appraised for less than the purchase price. This is a problem because the lender will only mortgage the appraised value.

Example

DetailValue
Purchase price$600,000
Appraised value$560,000
Mortgage (80% LTV)$448,000 (based on appraised value, not purchase price)
Your required down payment$152,000 (instead of $120,000)
Gap you need to cover$32,000 extra

Your options

OptionProsCons
Renegotiate the priceSaves cash; price reflects true valueSeller may refuse
Cover the gap with cashYou keep the dealRequires additional funds
Request a second appraisalMay get a higher valueCosts another $300–$500; not guaranteed
Submit a reconsideration of valueFree; provides new comparable dataAppraiser may not change their opinion
Walk away (with financing condition)Protects you from overpayingYou lose the property
Push back through your brokerBroker may have relationships with lender underwritersResults vary

How to submit a reconsideration of value

  1. Review the appraisal report — Ask your broker for a copy (you have the right to see it)
  2. Identify errors — Wrong square footage, missing renovations, incorrect lot size
  3. Provide better comparables — Recent sales of truly similar properties that support a higher value
  4. Submit through your broker — They send the reconsideration package to the appraisal company
  5. Wait for review — Typically 3–5 business days

Success rate: Reconsiderations succeed roughly 20%–30% of the time when strong comparable sales data is provided.

How to prepare your home for an appraisal (sellers and refinancers)

ActionImpact
Clean and declutterMakes spaces feel larger and better maintained
Complete minor repairsFix leaky faucets, patch drywall, replace burned-out lightbulbs
Provide a list of upgradesNew roof, furnace, kitchen — with dates and approximate costs
Ensure access to all areasBasement, attic, garage, crawl space
Provide recent comparable salesThe appraiser will research their own, but supporting data helps
Do not over-renovateCosmetic updates help; major renovations may not return full value

When appraisals are not required

SituationWhy
Insured mortgage (under 20% down)CMHC or other insurer may use automated valuation models (AVM)
Mortgage renewal with same lenderLender already knows the property
Some refinancesIf LTV is low and the lender’s AVM confirms value
Low-ratio mortgage (under 65% LTV)Lower risk to lender; some waive the in-person appraisal

Even when a physical appraisal is waived, the lender still assesses property value — they just use automated data instead of an in-person visit.
