I'm developing an R (or SAS) decisioning engine that requires input for whether a home is either for sale, foreclosed, or not for sale. I have a list of 10K addresses and would like to be able to pass these addresses to the API one at a time and have the for sale status returned.
I have tried Zillow, which comes close to giving me what I need (getdeepcomps call includes last sale date), however the data returned does not give me a current view of the market status for the address.
Has anyone found an api that returns this info?
