What Is a Property Tax Appeal Appraisal?
What Is a Property Tax Appeal Appraisal?
What Is a Property Tax Appeal Appraisal?
A property tax appeal appraisal is a professional, third-party valuation used to challenge your county’s assessed value.
It provides documented proof of your property’s true market value — and is often the key to a successful appeal.
These reports are commonly used in:
• Appeals filed with the Board of Equalization
• Disputes submitted to Assessor’s Office
• Legal and consulting support for both residential and commercial properties
At Authority Appraisals, every report is USPAP-compliant, local market-based, and designed to be accepted by county and legal review boards — giving your appeal the support it needs.

Overpaying on property taxes? You’re not alone.
Thousands of St. Louis-area homeowners and commercial property owners are over-assessed each year — often by mistake. A tax appeal appraisal can help you prove your property’s true value and reduce your bill.
Here’s when it might be the right move:
• Your county’s assessed value is higher than market value
• You recently bought the property for less than it’s assessed
• The home has physical issues — roof damage, foundation cracks, etc.
• You’re preparing documentation for a Board of Equalization appeal
• A consultant, attorney, or real estate agent suggested getting one

These reports must reflect the correct effective date, align with the county’s assessment timeline, and be defensible and unbiased.

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.

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.
