Which one do you need?
Appraisal, CMA or BPO
Three documents, three numbers, and only one of them counts as evidence. This is how to work out which one your situation needs.
| Appraisal | CMA | BPO | |
|---|---|---|---|
| Prepared by | Licensed or certified appraiser | Real estate licensee | Real estate licensee |
| Governed by | USPAP, and NJ Appraiser Board regulation | No valuation standard | No valuation standard |
| Independence certified | Yes, in writing and signed | No | No |
| Property inspected | Whatever the scope of work sets, disclosed on the report; interior here unless agreed otherwise | Varies; frequently exterior only | Frequently exterior only |
| Will a court receive it | Yes — though weight and admissibility remain the court's to decide | No | No |
| Written to IRS appraisal requirements | Yes; the value itself remains open to IRS review | No | No |
| What it costs | A few hundred dollars | Normally nothing | Low, and usually ordered by a lender |
| What it is for | Situations where somebody other than you has to accept the figure | Settling on a listing price | Lender portfolio and default work |
Accuracy is not what separates them
All three produce a number, and on an ordinary house in an active market the three numbers will often land within a few percent of each other. Most people take that as settling the question. It does not come close to settling it.
What separates them is who is obliged to take the number seriously. An appraisal is developed under a professional standard, by somebody the State has licensed, who certifies their independence in writing and can be made to answer for the analysis afterwards. The other two are opinions offered without that standard behind them, usually by somebody whose income depends on a transaction happening.
So "which is most accurate" is the wrong question. The right one is whether anybody other than you has to be persuaded — a lender, a county board, a court, the Division of Taxation, a mortgage servicer, or a sibling who has already decided what the house is worth.
When the free one is the right one
A three-bedroom colonial in a Bergen borough that has turned over a dozen similar houses since the spring, with nobody but you to satisfy? An agent's market analysis covers that, it is normally free, and it is prepared by somebody with a direct stake in getting the price right. Paying for a formal opinion there is a poor trade, and you will hear that on the phone rather than after the invoice.
Where the appraisal earns the fee instead:
- Estate and date-of-death, where the IRS and the Division of Taxation are downstream
- Divorce, where the other side will read every adjustment
- Litigation, where an opposing expert is paid to find the weak point
- PMI removal, where a servicer sets the rules
- A tax assessment appeal, where a county board decides whether to accept it
FAQ
Common questions
Is a CMA ever enough on its own?
Often, and anyone telling you otherwise is selling something. If you are working out an asking price for an ordinary house, in a town with recent sales of similar houses, and the only person who needs convincing is you, a competent agent's comparative market analysis will cover it and it normally costs nothing. The appraisal begins earning its fee at the moment somebody other than you has to accept the number.
Can my agent just do an appraisal for me?
No. Developing and communicating an appraisal in New Jersey requires a licence or certification issued by the State Real Estate Appraiser Board. A real estate licensee may prepare a comparative market analysis, and usually a broker price opinion, but neither document is an appraisal and neither may be held out as one. That boundary comes from the licensing statute rather than from appraisers protecting their own fees.
Why does a BPO not help in a contested matter?
A broker price opinion is not developed under USPAP, carries no certification of independence, and is generally written by somebody whose income depends on transactions happening. That does not make it dishonest — it means there is no professional standard behind it for anyone to test it against. Whether a tribunal admits a given document, and what weight it gives it, is the tribunal’s decision and no appraiser can promise you either. The practical difference is that an appraisal is built to survive being examined, and a BPO gives the other side nothing to cross-examine because there is nothing underneath it to attack.
What about the figure on a property website?
A statistical estimate generated without anybody ever seeing the property. It cannot know about the kitchen redone last year, the third bathroom that was never permitted, the roof at the end of its life, or the fact that the garden backs onto Route 46. As a starting point it is genuinely useful and I use the same public data myself. As evidence it is worth nothing, and no lender, county board or court is going to act on one.
Could you do both an appraisal and a CMA for me?
No, and not because of a house rule. This is an appraisal practice only — there is no brokerage arm here, no listing, and no commission at the end of anything. An appraiser holding an interest in the sale price is not independent, and independence is the entire thing you are paying for. Where a market analysis is what your situation actually calls for, you will be told so and pointed at an agent.
Next step
Still not sure which one you need?
Two minutes on the phone will settle it. Describe the situation, and where a free market analysis covers you — or where nothing formal is needed at all — that is what you will hear, before anything is ordered.
