What's in the HomesEstimate Formula?

We use proprietary automated valuation models that apply advanced algorithms to analyse our data to identify relationships within a specific geographic area between this home-related data and actual sales prices. Home characteristics such as house size, location or the number of bathrooms are given different weights according to their influence on home sale prices in each specific geography over a specific period of time. This resulting in a set of valuation rules, or models that are applied to generate each home's HomesEstimate. Specifically, some of the data we use in this algorithm include:
Physical attributes: Location, land area, house size, number of bedrooms, bathrooms and many other details.
Rates assessments: Property rates information, actual rates paid, exceptions to rates valuation assessments and other information provided by the local council records.
Prior and current transactions: Actual sale prices over time of the home itself and comparable recent sales of nearby homes.
