But there are real situations where only a credentialed opinion works, and in three states the question is not yours to answer. This page covers both. We are not an appraiser and we do not sell an appraisal. What we are is at the bottom.
What a diminished value appraisal actually is
It is a person. Someone with an appraiser credential reviews your vehicle, your repair file, or both, and signs an opinion of what the car was worth before the accident and after. What you pay for is a named professional who can be asked to defend that number, and standing in formal processes that accept an opinion only from a qualified person.
When you genuinely need one
1. You are invoking the appraisal clause on your own policy. Most auto policies contain one: if you and your own insurer cannot agree on the amount of a loss, each side names an appraiser, and if those two disagree, an umpire decides. That process is written to accept appraisers, and a software-generated report is not eligible for it, ours included. If you are heading there, hire a person.
2. The answer depends on someone looking at the car. If the fight is about repair quality — panel gaps, paint that does not match, a defect that shows up in person and not on paper — documents cannot settle it. The same goes for classic, modified, exotic or low-production vehicles, where market data barely exists and judgment does the work.
3. You expect to end up in front of a judge with testimony. Small claims often runs on documents. A larger or contested case may need somebody who can take the stand. For a court-ready opinion or legal advice, a licensed appraiser or an attorney in your state may be more appropriate than a self-help report.
4. The insurer has asked in writing for something specific. If so, follow it — and get their commitment in writing before you pay anyone.
5. You are in Connecticut, Nevada or Oregon. See below.
Connecticut, Nevada and Oregon
In these three states, valuing a vehicle for a fee is regulated, and the rules reach people working for a third-party claimant — which is what a diminished value claim usually is.
- Connecticut. Conn. Gen. Stat. § 38a-790 covers appraisers acting for third-party claimants.
- Nevada. NRS 684B covers appraising for a fee for third-party claimants, plus an in-state office.
- Oregon. ORS 819.482 requires a DMV Vehicle Appraiser Certificate for a paid opinion of vehicle value.
Because of those rules, we do not sell reports in Connecticut, Nevada or Oregon. That is us staying out of a licensed activity, not a judgment about your claim. You may want to contact a licensed professional in your state.
What a diminished value appraisal costs
From providers who publish their prices, as of our last review:
| What you get | Typical price | |---|---| | A rough range, no report | free to about $75 | | Automated report, nobody involved | about $20 – $90 | | Desk review by an appraiser, no inspection, sometimes with a demand letter | about $250 – $400 | | Appraisal including a physical inspection | about $475 – $775 | | Appraisal-clause or umpire work | bundled, or several hundred dollars more |
The inspection is what the big money buys. The same firm that charges $475 to $775 to come and look at your car will write the same report from documents for around $350. If nobody needs to see the car, you are choosing between paper and paper.
Watch for percentage fees. Some firms take a cut of what you recover. On a good outcome that costs far more than a flat fee, and in some states a percentage of an insurance recovery raises its own licensing questions.
Two tests before you spend this money. Is the number at stake big enough? Spending $500 to chase $900 rarely makes sense, so find out the size of the number first. Will the credential change the outcome? If the insurer's objection is "we used our formula", a second opinion may not move them any more than good evidence would. If the objection is about the car's condition, it will.
How to find one
"Appraiser near me" is the usual search, but proximity matters only when somebody has to see the car. For a desk review the person can be anywhere. Before hiring, check what credential they hold, whether the fee is flat or a percentage, and whether an inspection is included. Get the fee in writing.
Questions
Do I need an appraiser for diminished value?
Usually not. You need evidence: what the car was worth before, what the repair involved, and what buyers pay for cars carrying that record. You do need one for an appraisal clause or umpire process, when the dispute turns on inspecting the car, or when you expect testimony in court.
Who can do a diminished value appraisal?
Someone holding the credential their state requires. In Connecticut, Nevada and Oregon that credential is specifically regulated for paid vehicle valuations, including work for third-party claimants. Elsewhere the rules vary, so ask what they hold.
How much do you normally get for diminished value?
There is no reliable public average and we will not invent one. It moves with the car's value, the severity of the repair, your state's rules and how well the claim is documented. The free calculator gives you a range for your car in about two minutes.
Are diminished value claims worth it?
Find out the size of the number before you decide. A few hundred dollars on an older car may not be worth the paperwork.
Can insurance deny a diminished value claim?
Yes, and some states limit these claims heavily. A denial is not the end — a written response, a complaint to your state insurance regulator, or small claims court are the paths people use next.
How long does a diminished value claim take?
Your documents are ready in minutes. What happens afterwards is the insurer's timeline, and nobody can promise you a date. Our letter asks for a written response by a set date so the file does not go quiet.
What does "diminished value appraisal" mean?
Strictly, a valuation of the market value your car lost because of its accident history, written by a credentialed appraiser. In everyday use people apply the phrase to any written diminished value estimate, which is why this page separates the two.
