Jeff provided an important Opinion of Value for a boat-access-only cottage property with very large frontage on Devil Lake. The property was very unusual, and providing a credible Opinion of Value required significant research and sophisticated analysis. Jeff was consistent in providing guidance on the length of time, and cost, of doing the work, and in meeting deadlines. He responded quickly to requests for advice, and was thoroughly professional throughout the process. I would have no hesitation in recommending him to others.
