Short answer
A mortgage appraisal estimates the property’s market value for a specific lender, purpose and effective date. The appraiser identifies the property, confirms the required inspection scope, researches recent comparable sales, adjusts for meaningful differences, reviews marketability and reconciles the evidence into an opinion of value.
The client concern behind the question
The client sees a short visit and assumes the appraiser simply counts rooms or confirms the purchase price. Most of the work happens after the inspection, when the appraiser verifies property data, analyzes comparable transactions and applies the lender’s assignment instructions.
A practical Ontario example
Illustration only: A detached Brampton home sells for $1,050,000. The appraiser compares recent nearby detached sales but adjusts for lot, finished basement, garage, condition, size and sale date. A larger home that sold for $1,080,000 is not automatic proof that the subject is worth the same amount.
Questions Rajiv would ask first
- Who commissioned the appraisal and for what mortgage purpose?
- Was the assignment full interior, exterior-only, desktop or another permitted scope?
- What is the effective date of value?
- Which physical, legal and market characteristics require verification?
- What lender-specific concerns must the report address?
Practical routes to compare
- Provide accurate property access and factual documents promptly.
- Let the appraiser select and analyze evidence independently.
- Ask the mortgage broker which outstanding lender conditions remain after the value is received.
Realtor, appraiser and mortgage broker roles
The Realtor provides market context, comparable-sale evidence and offer or listing advice. The appraiser develops an independent opinion for the stated client, purpose, effective date and scope. Rajiv explains how the commissioning lender uses value, which approval conditions remain and what other lender structures may be practical. The lawyer addresses the buyer’s contractual exposure. A CMA, appraisal, purchase price and municipal assessment can all show different numbers because they do different jobs.
How value changes mortgage mathematics
The accepted lending value affects loan-to-value, down payment, available equity and sometimes pricing or insurance. Strong income does not replace inadequate property security. An A lender is usually considered first when borrower and property fit. Alternative lenders may take a broader view at higher cost. MIC and private mortgages can sometimes bridge a shortfall, including interest-only or flexible terms, but the total cost and written exit must be workable.
Verified public guidance
CMHC says professional appraisal considers physical and functional characteristics, recent comparable sales and current market conditions. AIC standards require an appropriate scope of work, property description, research, verification and meaningful comparison.

Pressure-test the answer
The plan may fail if the report cannot be transferred, the lender refuses another appraisal, new comparable sales do not support the requested value, property information is unverified, the appeal misses the deadline, or short-term financing has no realistic exit. Correct facts, preserve independence and run a fallback while any reconsideration is pending.
