Which one do you need?
Appraisal, CMA or BPO
Three documents, three numbers, one of them evidence. Here is how to tell which your situation calls for.
| 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 |
The difference is not accuracy
All three end in a number, and on an ordinary house in an active market those numbers will frequently land close together. People assume that settles it. It does not.
What separates them is who will accept the number. An appraisal is developed under a professional standard, by somebody the state has licensed, who certifies their independence in writing and can be questioned on the analysis afterwards. A CMA and a BPO are opinions offered without that standard behind them, generally by somebody whose living comes from transactions.
So "which one is most accurate" is the wrong question to be asking. The question is whether anyone other than you has to accept this figure — a court, the IRS, the Division of Taxation, a mortgage servicer, or a brother who has already made his mind up.
When the free option is the right option
Pricing a three-bedroom colonial in a town that has produced eleven similar sales in six months, with nobody but you to convince? A good agent's CMA will handle that and it will not cost you anything. Several hundred dollars for a formal opinion is a bad trade in that situation, and you will hear so on the phone rather than after the invoice.
Where the appraisal earns its 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
- Gift reporting, where the value should stop being reopenable
FAQ
Common questions
Is a CMA ever enough on its own?
Often, and anybody who says otherwise is selling you something. Where you are working out what to ask for an ordinary house, in a town that has produced recent comparable sales, 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 starts earning its fee at the point somebody else has to accept the figure.
Can my agent just do an appraisal for me?
No. Developing and communicating an appraisal in New Jersey requires a licence or certification from the Real Estate Appraiser Board. A licensee may produce a comparative market analysis, and in most circumstances a broker price opinion, but neither one is an appraisal and neither may be presented as one. That is a line drawn by the licensing statute, not a distinction invented by appraisers to protect their fees.
Why does a BPO not help in a contested matter?
A broker price opinion is not developed under USPAP, carries no signed certification of independence, and is usually written by somebody whose living comes from transactions. None of that makes it dishonest — it means there is no professional standard behind it for the other side to test it against. Whether any document is admitted, and what weight it carries, belongs to the tribunal, and no appraiser can promise you either. The practical difference is that an appraisal gives you something built to survive examination, while a BPO leaves the other side nothing to cross-examine and leaves you nothing to stand on.
What about the figure on a property website?
An automated valuation model is a statistical estimate produced without a human being ever looking at the house. It has no way of knowing about the kitchen that was redone last year, the addition that was never permitted, the roof at the end of its life, or the rail line at the bottom of the garden. As a starting point it is genuinely useful. As evidence it is nothing, and no court, servicer or taxing authority is going to act on one.
Could you do both an appraisal and a CMA for me?
Not on the same property in the same transaction — one capacity per matter, always. Where a CMA is what your situation actually calls for, that gets offered before an appraisal assignment is accepted rather than afterwards. An appraiser holding a contingent interest in the sale price is not independent, and independence is the entire thing you are buying.
Next step
Still not sure which one you need?
Two minutes on the phone will sort it. Describe the situation, and if a CMA covers it — or if nothing formal is needed at all — that is what you will be told, before anything is ordered.
