Recently, I had a case where an adjuster was negotiating an inherent lost market value claim based on values and condition descriptions found in Kelley Blue Book.
The amount of inherent lost value, or diminished value or DV as it is common to call it, that the adjuster was willing to pay was about $4000 less than what my research and opinion came out to.
Obviously, I argued that KBB was not accurate.
Naturally, the adjuster requested a synopsis on why I believed that using Kelley Blue Book was not a reliable method for researching diminished value.
I happily obliged the adjuster.
