I have a 2200 sq. ft lot that I intend to build 2 units on. It's a relatively small lot so it's hard to find another market comp in the area that has the same lot sq. footage. I am able to build 2 units roughly around 800-900 sq. ft. which is about 1600-1800 sq. ft of livable space which I am able to find market comparables but obviously without the same lot square footage. I'm sure there is some bearing into the size of the lot but I want to know how much it will affect it. I normally have buyers who are usually more concerned about the livable square footage of the lot versus the actual lot size. I've seen a 1200 sq. ft home with a 4000 sq ft lot sell the same as a home with a 7000 sq. ft lot with 1200 sq ft of livable space. I know appraising is an art and science and everyones perception is a little different.
