Appraisal vs. Comparative Market Analysis
By JC Pacific Corp Published 2026-09-01 Last professionally reviewed: September 2026
An appraisal is a formal valuation prepared by a qualified appraiser for a defined assignment. A comparative market analysis, or CMA, is a real estate agent's analysis used to help a buyer or seller understand market positioning.
What Is a CMA?
An agent may compare:
- Recent sales
- Active listings
- Pending transactions
- Property condition
- Location
- Market competition
- Listing history
- Buyer demand
A CMA may help a buyer formulate an offer or a seller select a listing strategy.
What Is an Appraisal?
An appraisal follows professional valuation standards and lender requirements when used for mortgage purposes.
Why Can the Values Differ?
Differences may result from:
- Comparable selection
- Adjustment methods
- New market information
- Property observations
- Assignment requirements
- Effective date
- Data availability
Frequently Asked Questions
Can a CMA guarantee the appraisal?

Is an online home estimate a CMA?
No. A CMA includes professional analysis, while an automated estimate is generated through a data model.
Which value determines the purchase price?
The buyer and seller negotiate the price. The appraisal may affect financing but does not independently rewrite the contract.
A CMA supports pricing and negotiation. An appraisal supports a formal valuation need, commonly connected to lending.
