I'm trying to get demographic data in the US at a level more specific than census block groups, so am going to try out using the zillow api and other similar apis to get home price and rental data for individual homes.
So far, I can't find a way to get the zillow api to return a list of every datapoint it has in its database (within a given area) in the form of a very large array, so my strategy currently is to make specific address requests to the API.
So what I need now is a list of every home address in a given area. My first guess is low hanging fruit, just get them from a phonebook. That's a good start but I don't know an open api or data dump for a phonebook currently. Will post sources as I learn them. What would be GREAT would be something like Open Street Map for homes. Not sure if anything like that exists though
