How can zestimate vary so much for identical homes, built at the same time? My home shows -$80k lessBoth homes are approx. 4,450 sq. ft. Both are on corner lots with same size property. The only real difference is that one home (mine) has a screened in, in-ground swimming pool w/ spa. The home without the pool has a zestimate of $444,500 and the home recently sold for $465,000. My home has a zestimate of $367,500.
