What is Diminished Value?

Diminished Value is the difference between the best price the owner could have gotten for the vehicle before the wreck and the best price the owner can get assuming – actually or hypothetically – that the vehicle is repaired as well as it can be repaired. When a vehicle gets wrecked, consumer demand goes down even if a repair shop does a great job fixing it. As demand goes down, so does the value of the asset.

Diminished Value FAQ’s

Frequently asked questions about Diminished Value and why we are the preferred claim specialists in Washington

Who is John Walker?

An Independent Expert Witness Appraiser in the following disciplines: Diminished Value (DV), Market Value, Poor Quality Collision Repair issues, Damage assessment and Total Losses. We are not an attorney or public adjuster. We provide reliable expert opinions, not legal advice. We gladly work for the consumer or the insurance industry because we are truly independent.

Who do I collect from?

That depends on the circumstances. In most cases, you collect from the at fault party insurance company; or else through your own underinsured motorist coverage if applicable. Who must pay your claim is ultimately a legal question.

What will it cost?

We charge a flat fee for our services, from $450 to $850 depending on what you request (Note: Exotic vehicles are quoted on an individual basis). Our report includes an accurate and research-based appraisal of your vehicle’s post-repair value, footnoted photos if we conduct an in person inspection, a CARFAX report if needed, and pre-loss market value comparables.

How long does it take?

The average turnaround is 60-90 days after you hire us. We would prefer to inspect your vehicle before repairs.

Can't I get an online report cheaper and faster?

That’s true, but no insurance company will take you seriously. Shortcuts don’t pay off.

What factors affect my vehicle's diminished value?

The value of your vehicle, the nature of the damage, whether you own or lease it, whether it has suffered prior damage, and others. An accurate appraisal considers many complicated factors.

Do I need an attorney?

Only an attorney can tell you whether you need an attorney. Some people hire attorneys, and others don’t. The people who do tend to have better outcomes, and the professionals handle the headaches and the up-front costs. Most attorneys offer free telephone or in-person consultations.
