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.
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.
