Jeanie Loyd
I had a great experience with Zach! My appointment was scheduled quickly, and Zach stayed in communication with me. He was flexible with his availability. On the day of my appraisal, Zach was prompt, courteous and friendly. He informed me of the next steps. Overall, it was a really great 5 star experience. Thank you, Zach!
Stephen Bezdek
Stephanie was great to work with. Her communication throughout the process was top notch, her questions were spot on and her final report was excellent. Her rationale for her final number was thoroughly explained and she provided ample documentation to justify that number. A true professional that I would recommend to anyone.
Vicki Christopher
I highly recommend Authority Appraisals. They are professional, very responsive, and happy to help you! I would definitely call them first for your appraisal needs.
Robert Schaeg
I'm very pleased with the service provided by Authority Appraisals. We had James come out and look at a piece property for Estate purposes. James took his time going through the house and based on how detailed the report was, I know he spent a lot of time researching to give me a fair and honest value for the property which I truly appreciate. I would definitely recommend Authority Appraisals to anyone that asked.
Caleb Singleton
Pam was out recently to appraise our house. She was so nice and efficient! She made the process so easy for us and had the appraisal turned around quickly to our lender. The whole team there is great to deal with and I have no reservations recommending them to anyone.
Adam Wiener
Easy 5 star review! Bad decisions are made when you fail to avoid those low quality appraisers who do not know how to properly produce an accurate appraisal. Zack and his team leave no stones unturned, they will measure and do the necessary research. You will get an accurate thorough written appraisal if you hire Zack
