Sorry you are going through this.
Two appraisers at the beach I like a lot, both in business a long time, knowledgeable of our community and real professionals are: Len Hileman at 904-270-2250 and Spencer Gregg at 249-1300.
Remember, a licensed professional has a code of ethics and guidelines to work with. If an appraiser did anything but an objective appraisal, he could risk losing his license. You are pretty safe to get a licensed, established appraiser.
Good luck. Here is something someone told me once: "I cried as they cut down the trees, and then when they were gone, I realized I could see the moon for the first time." I hope it is like that for you.
