How to find MLS data?

I often see the same real estate listings across many different websites. Is there a central pl开发者_如何学Goace where websites get their data from? How can I find an API or XML feed or aomething with real estate listings for a certain area?

Leonel, there are local Realtor Associations. They each operate their own database and MLS information. They then optionally share it with other groups like realtor.com, trulia.com, zilliw.com etc. But the data always goes to the local city/region Realtor association.

There is IDX - limited data and VOW full data that Realtors can get feeds / data dumps for their website. Most of the local associations run systems that use the RETS interface to export data in a standard way.

So you essentially need to contact the local association, and usually need to be a member of the association.

You think it would be easy data to get, but it's actually pretty well guarded. Trulia worked hard to build the relationships to get the data.
