The Zestimates that homeowners often present to appraisers can produce some interesting (and misleading) results. So much so, that I thought we could do a comparison of 12 randomly selected appraisals that were completed by our office and match them up against their Zillow Zestimates. Keep in mind that the appraisals have the benefit of a full property inspection by a human being. Zillow uses public records and complex algorithms. Here are the results.
|Lafayette Hill house||Appraisal: $600,000||Zillow: $529,000||
|Oreland house||Appraisal: $230,000||Zillow: $209,500||
|Gladwyne house||Appraisal: $585,000||Zillow: $633,500||
|Roxboro twin||Appraisal: $206,000||Zillow: $186,300||
|Conshohocken house||Appraisal: $350,000||Zillow: $279,600||
|Blue Bell house||Appraisal: $335,000||Zillow: $314,900||
|Chestnut Hill twin||Appraisal: $300,000||Zillow: $334,200||
|East Falls twin||Appraisal: $411,000||Zillow: $427,100||
|Center City condo||Appraisal: $755,000||Zillow: $634,200||
|Penn Valley house||Appraisal: $585,000||Zillow: $561,000||
|Rittenhouse Square townhouse||Appraisal: $1,900,000||Zillow: $898,700||
|Chester Springs home||Appraisal: $1,000,000||Zillow: $871,700||
As you can see there are some pretty significant deviations between the appraised value and the Zillow Zestimate. In one case, Zillow was off by more than 111% (this seems like a fluke) but, in other examples as close as 3.77% (not bad!).
Bottom line, Zillow is a tool…a starting point. It’s wonderful for neighborhood data, graphs and general sales information. It’s probably not the best place if you’re looking for assistance with making definitive decision.
