Total Loss Appraisals
If your vehicle was deemed a total loss by the Insurance company and you are not satisfied with their offer, you have the right to invoke the appraisal clause and hire Houston Auto Appraisers in order to determine the actual cash value (ACV) of your vehicle. An IACP certified auto appraiser will go to the location of the vehicle and determine the vehicles pre/post-loss condition and put together our detailed total loss appraisal that will be a certified document with critical evidence needed to support your claim. Should the two appraisal companies not come to a mutual agreement on the fair market value of your vehicle, an umpire will have to be selected and his or her final decision is binding. In most cases, we rarely need the assistance of an umpire. The Bureau of Certified Auto Appraisers maintains a list of qualified Umpires. See www.BOCAA.org.
