Comparative Market Analysis vs. Appraisal: What's the Difference?
The short answer: A comparative market analysis (CMA) is a real estate licensee's analysis of comparable properties, used to help an owner or buyer think about price. An appraisal is an unbiased opinion of value, and in New Jersey an appraisal assignment can be performed only by a state licensed or certified appraiser (or someone working under one's direct supervision) (N.J.S.A. 45:14F-21). NJ rules say plainly that a CMA "is not an appraisal" (N.J.A.C. 11:5-6.1(m)).
The two often look alike on paper, since both compare a home to similar properties. The difference is who prepares them, for whom, and what they can be used for.
What is a comparative market analysis?
A CMA is the pricing work an agent does when a seller asks "What should I list for?" or a buyer asks "What should I offer?" Typically the agent compares the property with similar homes that have recently sold, are under contract, or are on the market, and suggests a price range.
New Jersey's advertising rule treats a CMA as something distinct from an appraisal. Any written CMA a licensee gives a consumer must include a statement that it is not an appraisal and shouldn't be considered the equivalent of one. That statement must be printed as large as the main text of the CMA (N.J.A.C. 11:5-6.1(m)1i).
What counts as an appraisal under NJ law?
The Real Estate Appraisers Act defines an appraisal as "an unbiased analysis, opinion or conclusion relating to the nature, quality, value or utility of specified interests in, or aspects of, real estate." It splits appraisals into a valuation (an estimate of value) and an analysis (any other study of the property) (N.J.S.A. 45:14F-2).
An appraisal assignment is a job where the appraiser acts, or would be seen by others as acting, as a disinterested third party (N.J.S.A. 45:14F-2). That's the core contrast. An agent preparing a CMA usually isn't disinterested. The agent may hope to win the listing or close the sale.
Who can do each one?
| CMA | Appraisal assignment | |
|---|---|---|
| Who prepares it | A real estate licensee | A state licensed or certified real estate appraiser, or someone assisting under their direct supervision |
| Who it's for | The owner or prospective buyer, for their own use | Any party, including lenders, courts and government bodies |
| Required label | Must state it's not an appraisal (written CMAs) | Only a licensed or certified appraiser may call it a "licensed" or "certified" appraisal |
| Source | N.J.A.C. 11:5-6.1(m); N.J.S.A. 45:14F-21(c) | N.J.S.A. 45:14F-21(a)–(c) |
The Appraisers Act has its own regulator, the State Real Estate Appraiser Board (N.J.S.A. 45:14F-2), separate from the Real Estate Commission. A real estate license doesn't make you an appraiser.
Can an agent give pricing advice without an appraiser license?
Yes, within limits. The Appraisers Act says it doesn't stop an unlicensed person from giving "counsel and advice on pricing, listing, selling and use of real property," for a fee or not, directly to a property owner or prospective purchaser, as long as it's solely for that person's own knowledge or use (N.J.S.A. 45:14F-21(c)).
That's the space a CMA lives in. Hand that same analysis to a third party, like a lender or a court, as an independent valuation, and you're in appraisal-assignment territory.
What about broker price opinions?
A broker price opinion (BPO) is an estimate prepared by a broker or agent of a property's probable selling price (the federal definition the Board adopted). The New Jersey Real Estate Appraisers Board issued an advisory opinion in 2012 taking the position that a BPO is an appraisal under New Jersey law. It said a broker may prepare one only within the statute's two exemptions: advice given directly to an owner or prospective purchaser for their own use (45:14F-21(c)), or a BPO for a state or federally chartered bank, savings bank or savings and loan in a federally related transaction where federal law doesn't require a licensed or certified appraiser (45:14F-21(f)) (Appraisers Board advisory opinion, Nov. 27, 2012).
The Board noted that its opinion is general guidance, not a formal Attorney General's opinion. If a request for a BPO doesn't clearly fit an exemption, check with your broker before you agree to it.
How does this show up on the NJ real estate exam?
Valuation is 8% of the national portion of PSI's salesperson outline, and it covers this exact line (PSI bulletin):
- Appraisals: what appraisals are for, situations that require a licensed or certified appraiser, brokerage actions that amount to unauthorized appraisal practice, and the general steps in the appraisal process
- Estimating value: economic principles, plus the sales comparison, cost and income approaches
- CMA: CMAs, BPOs or equivalents, and how automated valuation models (AVMs), appraisals and CMAs compare
For the full outline and exam format, see our PSI exam guide.
How do you keep them straight?
Ask three questions:
- Who prepared it? A licensee, or a licensed or certified appraiser?
- Who is it for? The owner or buyer's own decision, or a third party such as a lender?
- Is the preparer disinterested? An appraiser in an assignment acts as an unbiased third party. An agent usually has a stake in the deal.
If the answers are "licensee," "the owner" and "not disinterested," it's a CMA, and in writing it has to say it isn't an appraisal.
CMAs usually come up at the listing presentation, so it helps to know the types of listing agreements. For how license titles differ, see agent vs REALTOR® vs broker, and for where CMAs fit in the workday, see what a NJ agent does all day.

Frequently Asked Questions
Is a CMA the same as an appraisal in New Jersey?
No. NJ's rules state that a comparative market analysis is not an appraisal. An appraisal is prepared by an appraiser authorized by law (N.J.A.C. 11:5-6.1(m)).
Can a real estate agent do an appraisal in NJ?
Not as a real estate licensee. Only a state licensed or certified appraiser, or someone assisting under one's direct supervision, may perform an appraisal assignment on New Jersey real estate (N.J.S.A. 45:14F-21(c)).
Can an agent charge for pricing advice?
The Appraisers Act allows counsel and advice on pricing, "for a fee or otherwise," given directly to an owner or prospective buyer for their own use (N.J.S.A. 45:14F-21(c)). Any pay for that work still flows through your broker (N.J.S.A. 45:15-16).
Are broker price opinions allowed in New Jersey?
Only within narrow exemptions, according to the Appraisers Board's 2012 advisory opinion, which treats a BPO as an appraisal (advisory opinion).
