Course Evaluations

Course Evaluations Summary »


"I have to commend you on the outstanding presentation you have put together on this subject. Your knowledge of high performance 'green' building, as well as appraising the same, is clearly demonstrated throughout the course. The coordination of getting us all the course materials and organizing a site visit is exemplary.  I can’t remember the last time I have taken an education offering that has so thoroughly energized me and kept me wanting to learn more. Thank you for giving us this wonderful opportunity. It is much appreciated."
— Lorrie Beaumont, LB Appraisal Associates (Westwood, MA)

"What a great class! Taylor was a very knowledgeable and effective instructor. I probably got more out of this course than any other course I've taken...especially since Green Appraising was completely new to me and he cleared up many misconceptions I had about building Green. Taylor knows and understands, first-hand, the material that was discussed. He was able to articulate his understanding of Green Building in a way that is understood by Appraisers that, otherwise, have really no Green Appraising background. I would not mind taking it again as a refresher in a couple years, especially since we are only at the beginning of valuating Green homes." 
— Ben Sadtler, AGA, Homestead Appraisal, LLC (Richmond, VA) 

"Taylor was the most interesting and informative appraisal instructor I have ever had. His knowledge and his conveyance of same is a model which I would love to see copied." 
— Melanie H. Kidd, AGA, Kidd and Company Realty, LLC (Richmond, VA)" 

"This was an excellent class - every appraiser could benefit from attending. The focus on the topic from an appraisers perspective is what made it most valuable. I would not hesitate to take a follow-up course from this excellent instructor. I would highly recommend this course to every appraiser." 
— Walt Manz, AGA, Real Estate Valuation Services (Richmond, VA) 

"The Appraising Green Homes workshop was one of the most informative and interesting class I have taken as an appraiser. It was gret to have someone fully explain the how and why of the elements of sustainable housing. I have already recommended this class to other appraisers who were unable to attend this past class. I am now confident with my evaluation of green and energy efficient elements in my appraisals." 
— Denise M. Devore, AGA, Certified Appraisals LLC (Richmond, VA) 

"Valuable insight into green build technology and useful methodology for identifying energy saving components in residential construction." 
— Robert Butler, AGA, Landguard Appraisals (Birmingham, AL) 

"I found the course to be both informative and useful. As green building trends continue to grow, this course is at the cutting edge of providing knowledge to appraisers on how to evaluate and explain to the users of their services just how 'Green' features affect the value of a property." 
— Charles Robertson III, AGA, Regal Realty LLC (Birmingham, AL) 

"Very well done! This has been the best and most enjoyable multi day CE course that I have ever taken. Taylor is well spoken and exhibits a level of erudition that is clearly lacking in most CE classes. He was knowledgeable, and well prepared and appears to have no agenda, unlike most other 'green' presenters. The Green Movement is coming, as we all know, so Taylor's course is not to be missed!" 
— Jason J Pustek, AGA, KP Appraisal Services (Silverdale, WA) 

"I greatly enjoyed the class. I can see that green homes will probably be a significant part of future building in my area, and the knowledge of appraising such properties will be a good tool for future business for my company." 
— Lori Kaiser, AGA, Kaiser Appraisal Services, Inc. (Birmingham, AL) 

"Any appraiser who did not take the Green / AGA appraisal CE Classes taught by Taylor Watkins really missed out. While I don't think that Green is here yet, it is definitely coming and taking classes like this allow appraisers to get ahead of the curve, as well as look at how appraisers will have to adapt what we do to include this new Green information as it becomes available to us. Again, thank you Taylor Watkins and Ryan Harper for making this available." 
— George E. Nervik, AGA, (Silverdale, WA) 

"The class helped clarify the terms of Green Building and Energy Efficiency and how they are applied. With better understanding I can now be more prepared to consider how energy efficient building and sustainability are valued by buyers and sellers." 
— Rene Drake, AGA, Drake Appraisals (Silverdale, WA) 

"Many homes in my area are beginning to include buildings strategies for energy efficiency. This course helped me to understand the effects of different energy efficient items and how to value those on my appraisals! Best CE in years!!" 
— Anonymous Survey Participant 

"Taylor Watkins presents a balanced approach to the appraisal of 'green' property. He exposes the bias and pitfalls of green appraising and explains how market derived adjustments may be demonstrated and applied." 
— Anonymous Survey Participant 

"This is an excellent course for every day appraising!" 
— Michael Small, AGA, Certified Residential Appraiser (Richmond, VA) 

"This class was very informative and distilled the 'green construction valuation challenge down to a practicle, everyday appraisal scenario." 
— William (Frank) Wright, AGA Premier Appraisal Group (Richmond, VA)
