What our Clients Say

I liken the product to a football game were you start out going eighty yards in the first play by using Appraiser and then just having to fine tune from there to get to the end of the reappraisal.

Sumner County TN, Property Assessor

Data cleansing was obviously a very big part of it and then of course validating that information was wonderful.

Wilson County NC, Tax Administrator

It's very easy for us to justify the cost because it just saves so much time and so much work in our reappraisal so we found that it was a very good product and a very good investment.

Sumner County TN, Property Assessor

We use it to verify and create values for the next reappraisal using the market value approach rather than something like a cost basis which really just doesn’t seem to fit into a market as fast growing as ours.

Montgomery County TN, Assessor of Property
