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?

No.

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.
