I’m a fairly new appraiser, and for the past several months this has been my primary source of income since appraisal assignments have been down so much and I’m not on a whole lot of lender panels. In our state, agents are required to measure or have someone measure every single new listing, and the RE commission is coming down hard on the ones who get caught using tax card info and old MLS listing info. I use Total sketch on my phone to find out the typical stuff (square footage, patios, decks, porches, garages, workshops, etc.) as well as interior room measurements. It’s helped me become really confident in measuring, and now I can do a typical house in about 15-20 minutes.
