Short answer
A Realtor’s comparative market analysis helps a buyer or seller understand positioning and likely market range. A mortgage appraisal is an independent valuation completed for a stated purpose, client and intended user, usually under the commissioning lender’s requirements. A strong CMA can provide useful evidence, but it does not bind the lender or replace an appraisal the lender requires.
The client concern behind the question
The Realtor supports the purchase price with several sales, so the buyer assumes financing value is settled. The lender’s appraiser uses a different effective date, tighter property match or different adjustments and supports less.
A practical Ontario example
Illustration only: A Realtor’s CMA includes active listings, recent sales and a renovated model to advise an offer. The appraiser focuses on closed sales and adjusts for differences under the lender assignment. Both professionals can act reasonably and still reach different ranges because their purpose and evidence are not identical.
Questions Rajiv would ask first
- Was the CMA prepared for listing, buying or negotiation?
- Does it separate sold, active, terminated and conditional listings?
- Are the properties genuinely comparable in type, size, lot, condition and location?
- Is the CMA date close to the appraisal effective date?
- Will the lender accept additional market evidence through its review process?
Practical routes to compare
- Use the CMA to make a better pricing decision before offering.
- Use the lender appraisal to determine the mortgage value accepted for that file.
- When results differ, compare data and facts rather than attacking either professional.
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 describes an appraisal as a professional assessment used in mortgage lending. AIC requires the purpose, intended use, scope and assumptions to be stated. A Realtor CMA is real-estate market advice rather than the lender’s appraisal report.

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.
