Counselors at Appraisal®

An Elite-Rated member of the peer-voted SuperAppraisers® Global Network of internationally-recognized appraisers.

Appraisal dispute resolution requires highly-trained—highly-skilled—highly-credentialed—unimpeachable appraisal specialists with decades of experience that are specifically trained and accredited to serve as independent—third-party—neutrals to adjudicate appraisal disputes.

Equity Development Systems® pioneered the review appraisal profession and directed the development, writing, and implementation of the review appraisal Principals of Valuation and best practices that are taught to and in use today by professional valuers, legal experts, and government agencies throughout-the-world. Our experts have handled Billions-of-Dollars at issue and our review appraisals have been cited by U.S. regulators as "The measure by which all review appraisals should be judged.”

Our discipline-specific and multidisciplinary experts are uniquely qualified—internationally accredited—American Society of Appraisers (ASA), Royal Institution of Chartered Surveyors (RICS), Appraisal Institute (MAI), well-published luminaries in the global valuation communities. They include Uniform Standards of Professional Appraisal Practice (USPAP) and International Valuation Standards (IVS) instructors, and Value Adjustment Board (VAB) Magistrates and former state / federal appraisal regulatory compliance officers. We hold the only RICS Expert Witness Accreditation Service (EWAS) certification in the Americas and one of only a handful of such certifications in the world.

We provide comprehensive appraisal dispute resolution services in all disciplines of valuation and asset classes, tangible and intangible, i.e., Real Estate, Business Valuation, Intellectual Property, Personal Property, and Machinery and Technical Services.

We specialize in handling complex multidisciplinary and multi-jurisdictional appraisal dispute resolution matters involving two or more asset classes. As an example; a dispute wherein multiple international locations and multiple disciplines of valuation are at issue e.g., Real Property, Business Valuation (Business Income), and Machinery and Equipment. Unlike other—lesser—ADR services, EDS will assign one of its internationally accredited valuation experts from each respective discipline of valuation at issue to contribute to the process. This ensures independent—credible findings that will withstand challenges and scrutiny from regulatory, judicial and taxing authorities.
