Property Data Used Makes a Difference
Utilizing more than 80 million homes in our property database across all 50 states and representing 99% of the US population, and valuation software developed by Automated Valuation Model Analytics, our property AVM:
Eliminates mobile homes, multi-million dollar homes, farms or agricultural land and large multi-unit rental properties from the calculations.
Limits valuation to only single-family homes, condominiums, and small multiple family properties (one-to-four units).
Requires a minimum of 15 comparable properties and may use as many as 100 properties to generate its estimates.
Every property receives a unique confidence score.
This confidence score represents the precision of the AVM estimate and measures the deviation between the range of values and the point value itself. To provide the most transparent measure of variability in the estimates, we provide the larger of differences between the low and high value and point estimate.



To gauge the accuracy of automated valuation model, we have compared our real estate valuations to actual sale prices over a recent three month period.
This chart highlights the overall distribution of the absolute differences between our AVM values and observed sale prices.
