What role does property appraisal play in my mortgage?

Property appraisal accurately assesses the collateral value securing your mortgage.

Key Points

  • Lenders use different methods to determine your home's value, including appraisals and online tools.

  • Lenders carefully check how they estimate property values to make sure they're accurate.

  • Your lender has processes to manage the appraisal and value of your home as security for the mortgage.

  • The assessed value of your home should reflect its true market price and use.

  • If you have a smaller down payment, the lender will be extra careful about the home's valuation.

  • Appraisals are done professionally by qualified, independent appraisers.

Related Questions

How does the stress test affect my 2026 renewal options?

Same-lender renewals and uninsured straight switches (OSFI, November 21, 2024) are exempt from the prescribed MQR. A refinance, an insured switch, or any increase in loan amount still requires the stress test — greater of 5.25% or contract + 2%.

What's the difference between insured and uninsured mortgage renewals?

Insured mortgages face stricter CMHC/Sagen constraints while uninsured mortgages enjoy flexible OSFI-only guidelines.

Should I consider switching lenders or negotiate with my current lender?

Your switching decision hinges on rate differential versus requalification risk, with break-even analysis determining optimal strategy.

When should I start my mortgage renewal process?

Start your renewal process 120-180 days before your current term expires to maximize your strategic options.

Consider this example scenario, comparing hypothetical property valuations under different appraisal approaches:

ScenarioProperty ValueRationale
