Close More

Join us for this short course on ADU appraisal providing the latest in ADU valuation as the trend grows across the country.

Appraisers, today more than ever, need a thorough understanding of the role ADUs play in the real estate market. Learn why appraising an ADU is challenging and fundamentally different from multi-unit appraisals. Denis DeSaix of MetroCal Appraisals will cover best practices, what is legal, highest and best use, approaches to value, and cost vs value.

This one-hour course is intended for a national audience of Appraisers, Architects, Lenders, Real Estate Professionals, Developers, Builders/Contractors, Remodelers, Code Officials, and Consultants in markets where ADUs have been recently legalized, and are becoming a more popular form of development, as well as those in matured markets looking to increase your knowledge of the ADU Appraisal process.



The webinar will conclude with a 30-min Q&A session with our instructors:
