Appraisal Services

Our team has over 100 years of experience in the valuation, consulting, financing, and marketing of commercial real estate.

Capstone Appraisal Service was established to address an obvious need for competent commercial appraisal services provided by persons familiar with the West Michigan real estate market.  

We provide appraisal reports in accordance to the Uniform Standards of Professional Appraisal Practice (USPAP) for use with tax assessment appeals, estate valuations and commercial lending. Other services we provide include “highest and best use” analysis, appraisal consulting, and litigation support, including expert witness testimony.  Contact our team to discuss how we can best meet your appraisal needs.

Our Difference

Our experience as brokers and owners gives us a perspective beyond the purely academic analysis so prevalent in the appraisal business.  No appraisal analysis is complete until one of us “takes a seat on the curb” across the street from the property and considers what a prospective purchaser would really pay for the asset in question.  We will never short-change the analytical components of an appraisal assignment, but our clients will always have the benefit of a licensed and active broker having assisted in the valuation process, thereby assuring a “real world” perspective on the value of the property being appraised.
