Question: are zillow property values accurate?
Answer: According to Zillow, most Zestimates are "within 10 percent of the selling price of the home.”4﻿ But Zestimates are only as accurate as the data behind them, so if the number of bedrooms or bathrooms in a home, its square footage, or its lot size are inaccurate on Zillow, the Zestimate will be off.
