It doesn’t look like Buddypress would be the most suitable script to develop a site like that. Zillow is an interface on a bunch of databases for homes, agents, lenders, etc. You’d have to adapt the users and post tables in WordPress, which aren’t very flexible…, or develop something around it.

Are there any open source PHP scripts more suitable for this kind of site? Can’t think of any.
