I don't understand the logic of why it picks the comps it does.
It's a 70's house on a half acre lot. The AVM "data from tax records" says it is 2,592 SF living area, but it is a split foyer, and the assessors building summary says 2,593 SF living area but 1,343 SF on the main level. The AVM doesn't know it is 1,343 SF with 1,200 SF basement.
Because of that, it looks like it selected these 90's and 2000's homes that are 2,000+ SF on two above grade levels. I am not sure if the AVM would have chosen those 2000's homes if it knew that the subject was actually 1,300 SF with basement.
