In a development where units are almost exactly alike, why do you use comps from outsideOur development, Summit Enclave, has 3 bldg styles: Court homes(good quality), Townhomes(better), Ranch Duplexes (best quality). The Duplexes cost, and still sell for, more than the other types of units, but Zillow always uses the other units and old homes outside of the development as comps, resulting in inaccurate valuations. There are only 2 models of duplexes, one having 150 s/f more than the other. There are 86 of these units. The fairest (and easiest) valuation is to use sales/ for sales figures of these units to establish a more accurate valuation. The most recent sales of these units have been $164,000, $145,000, $154,000, but Zillow's valuation is in the low 130s.
