Home Value AVM

home value data api

Why are we letting ‘that Z company’ continue to steal our traffic? My ‘Guesstimate’ says that it’s because no-one has made a competitive solution affordable, until now. Home Junction’s proprietary AVM has been commercialized and in use for over 20 years, and we have now created a home value widget for real estate applications. This is one powerful, highly-detailed home value estimator tool.

Engage Your Visitors With Interesting Market Stats & Sales Activity
