CMA vs Appraisal: What Sellers Need to Know
A comparative market analysis (CMA) is an agent’s estimate of what your home could sell for, built to set a listing price. An appraisal is a formal opinion of value from a licensed appraiser, and it is usually ordered by a mortgage lender to protect its loan. They look alike on paper, since both lean on recent comparable sales, but they answer different questions, carry different weight and are paid for in different ways. If you are deciding how to sell a house, knowing which number matters when can save you weeks and real money.
TL;DR
- A CMA is an informal price estimate from a real estate agent. An appraisal is a formal valuation from a licensed appraiser, usually required when a buyer uses a mortgage.
- A CMA is typically free to the seller. In the 2022 NAR appraisal survey, the median appraisal cost was $500, with a median wait of 14 calendar days after contract acceptance.
- A broker price opinion (BPO) sits between the two: an agent-produced value opinion, often requested by a lender or servicer, but not an appraisal.
- A low appraisal can stall or reprice a financed sale. A cash sale does not depend on a lender’s appraisal.

What a CMA is and who it is for
A CMA is a pricing tool. An agent pulls data from the Multiple Listing Service (MLS) and compares your home with similar properties that have recently sold, are under contract or are still active. The agent then adjusts for differences in size, location, amenities and condition and suggests a listing price or a price range. The National Association of Realtors consumer guide on pricing lists those same factors as what agents weigh when recommending a price.
Three things define a CMA:
- The client is you. It is prepared for the seller (or sometimes a buyer) to decide on a price.
- It is an opinion, not a certified valuation. NAR notes that a CMA is not performed by a licensed appraiser and does not follow the same regulatory standards as a formal appraisal.
- It is usually free. Agents commonly provide it as part of competing for your listing, so it is a sales tool as well as a valuation tool.
That last point matters. An agent who wants the listing has a reason to present an appealing number, and an agent who is cautious may suggest a lower one to sell fast. A good CMA shows its comparable sales so you can judge the logic yourself.
What an appraisal is and who it is for
An appraisal is a written opinion of what a property is worth, prepared by a licensed professional. The Consumer Financial Protection Bureau describes it as a document that explains what makes the property valuable and how it compares with other properties in the area.
The key difference is who the appraiser works for. Even if the buyer pays for the appraisal at closing, the lender is the client. The appraiser is expected to be independent, impartial and objective, and the report exists to show the lender that the home supports the loan amount.
In Michigan, valuation work is regulated. The state’s Bureau of Professional Licensing says anyone who issues an opinion of value of real property must be a licensed appraiser, and it carves out market analyses by licensed brokers and salespeople made for limited purposes, such as helping a client with a listing or purchase decision. That is the legal reason a CMA from your agent cannot stand in for an appraisal.
CMA vs appraisal at a glance
| CMA | Appraisal | BPO | |
|---|---|---|---|
| Prepared by | Real estate agent or broker | Licensed or certified appraiser | Licensed agent or broker |
| Main purpose | Set a listing price | Support a mortgage lending decision | Give a lender or servicer a quick value opinion |
| Who it serves | The seller or buyer | The lender | Usually the lender or servicer |
| Formal standing | Informal opinion | Regulated, formal report | Opinion, not an appraisal |
| Typical cost to you | Usually free | Median $500 in the 2022 NAR survey | Paid by the requester |
| Inspection | Often a walk-through, sometimes none | Property inspection and written report | Often an exterior or limited look |
| Can you get a copy? | Yes, from your agent | Yes, for a first-lien mortgage application | Depends on who ordered it |
The BPO deserves a note, since many people search for it next to these two. A broker price opinion is produced by a licensed broker or agent who may know the local market well but does not need appraisal credentials. Lenders and servicers sometimes order one when a loan is in trouble, for example before a foreclosure decision. It is closer to a CMA than to an appraisal.
How the numbers can differ
Sellers are often surprised when a CMA says $210,000 and an appraisal says $195,000. That gap does not mean someone made a mistake. Several things drive it.
Purpose. A CMA estimates where a home could be listed to attract offers. An appraisal estimates support for a loan. A CMA may price slightly ambitiously to start negotiation. An appraiser has to defend each figure.
Adjustments. NAR explains that appraisal adjustments must be defensible and based on market reaction, not simply on what an upgrade cost. A new kitchen that cost $40,000 does not automatically add $40,000. The appraiser looks at what buyers are actually paying for those features right now. If you are weighing a remodel before you sell, this look at how neighborhood comps affect renovation value explains why the neighborhood sets a ceiling on what improvements return.
Timing. Appraisals have a short shelf life, especially in a changing market. NAR advises checking the date of any appraisal, because its effective date can differ from the inspection date. An old appraisal is a weak argument for today’s price.
Data. Two professionals can choose different comparable sales. NAR lists timing, purpose of the valuation and the comparables used among the factors that cause disparities, even between two appraisers.
Sales price, appraised value and why deals stall
The sales price is simply what you and a buyer agree to. The appraised value is a separate opinion that checks that agreement. NAR explains that when the appraisal comes in below the contract price, the loan may not be approved at that amount, and the price may need to be renegotiated. Appraisers are often blamed for killing a deal, but they are performing a required risk check for the buyer’s financing.
If you are selling to a buyer with a mortgage, a low appraisal usually leaves four paths:
- Lower the price to the appraised value.
- Ask the buyer to cover the difference in cash.
- Split the gap through negotiation.
- Challenge the appraisal or walk away from the contract.
Each path costs time. When you are facing a foreclosure date, a probate timeline or a house that needs repairs, a financed sale that falls through at the appraisal stage can be painful. Our guide on options when an appraisal comes in low in Detroit walks through them in detail.
What each one costs
A CMA from an agent is typically free, but you pay indirectly if you then list with that agent and pay a commission. If you want to see what those costs look like in Michigan, read about the hidden costs of selling with a realtor.
Appraisal costs vary by property type, location and complexity. The 2022 NAR appraisal survey puts the median at $500, with 71% of respondents reporting $400 or more. Turnaround is a median of 14 calendar days after contract acceptance, and 60% of respondents reported waits of 11 days or longer. Those are survey figures from 2022, so expect today’s local quotes to differ.
A buyer ordinarily pays for the lender’s appraisal, but you may pay for a private appraisal yourself if you need one for an estate, a divorce or a pre-listing price check.
Which one do you need?
Use this as a rule of thumb:
- You are thinking about listing with an agent. Ask for a CMA, and ask to see the comparable sales behind it.
- You need a value for probate, divorce, taxes or a legal dispute. You need an appraisal from a licensed appraiser, because it carries formal weight that a CMA does not.
- Your buyer is using a mortgage. An appraisal will happen whether you want it or not. Price your home with that in mind.
- A bank or servicer is evaluating a distressed loan. Expect a BPO or an appraisal to be ordered on their side.
- You want to sell as-is for cash. Neither is required to receive an offer from a cash buyer, though you can still get one if you want a second reference point.
If you do receive a lender-ordered appraisal on a purchase or refinance of your own, the CFPB says you have the right to a free copy for a first-lien mortgage, and lenders should provide it no later than three days before closing. If you find errors, raise them with the lender, and you can submit a complaint to the CFPB if you are not getting answers.
Our perspective on CMAs, appraisals and cash sales
We have bought homes in Metro Detroit for more than 16 years, and the same pattern comes up again and again. A homeowner gets a CMA with an optimistic number, lists the house, finds a buyer with a mortgage, and then waits for an appraisal that may or may not agree. For a home in good shape, that process can work fine. For a home that needs a roof, has an outdated kitchen or came through an inheritance, the appraiser has to account for the condition, and lenders can be strict about it.
We would rather you understand the numbers than rely on any single one. Use a CMA to see how the market treats similar homes. Use an appraisal when a lender or a legal process requires it. And if time, condition or cost is the bigger concern than squeezing out the top price, weigh what repairs, commissions, appraisal risk and months on the market really cost. Our renovation costs vs cash offer decision guide puts those trade-offs side by side.
When we make an offer, we do it as the buyer. We buy as-is with no repairs or cleaning required, there are no realtor fees or commissions, and we cover standard closing costs. We aim to give you a fair cash offer within 24 hours and can close in as little as seven days. Because we are not borrowing against the house, there is no lender appraisal standing between you and closing. Our article on how appraisal-waived cash sales work explains how to verify that kind of offer.

Getting the most from whichever number you use
- Ask for the comparables. Whether it is a CMA or an appraisal, the comparable sales are the evidence. Check that they are recent, nearby and similar in size and condition.
- Be honest about condition. A CMA that assumes your home is in average shape will overstate the price if it needs work. Walk the agent through every problem.
- Disclose permits. Unpermitted work can complicate both appraisals and financed sales. See how to sell a house with unpermitted work.
- Check the date. Do not rely on an appraisal from a prior year to price a house today.
- Compare more than one opinion. Two CMAs from different agents often reveal how much room there is in a price.
FAQ
Is a CMA the same as an appraisal?
No. A CMA is an agent’s informal estimate used to set a listing price, and it is not prepared by a licensed appraiser. An appraisal is a formal, independent opinion of value from a licensed professional, typically ordered by a lender. Lenders will not accept a CMA in place of an appraisal.
Is a CMA or an appraisal more accurate?
Neither is guaranteed. An appraisal follows stricter standards and relies on verified comparable sales, so it carries more weight with lenders and courts. A CMA can reflect current buyer demand and local knowledge, but it is an opinion. NAR stresses that an appraiser gives an opinion of value, not a guarantee.
How much does a CMA cost from a realtor?
Agents usually prepare CMAs for free when they are hoping to list your home. The cost shows up later if you hire that agent and pay a commission. An appraisal, by comparison, had a median cost of $500 in the 2022 NAR survey.
What is the difference between a BPO and an appraisal?
A BPO is a value opinion from a licensed agent or broker, often ordered by a lender or servicer, and it does not require appraisal credentials. An appraisal comes from a licensed appraiser under formal standards. A BPO is faster and cheaper but carries less weight.
Do I need an appraisal to sell my house for cash?
Not for a lender, since there is no loan to approve. You may still want an appraisal for legal reasons, such as settling an estate. Otherwise, a cash buyer’s offer is based on the home’s condition and the local market, and you decide whether the number works for you.
