Wow that's are great ideas !!
Finally !!. I just upload a construction page version to the new domain. It's in spanish by now but I'll be translating to english also.
If you like try this domain:
http://www.propimap.com

I'll be adding there the development and also telling on the wiki each step.
I'll take into account all the ideas. Tomorrow I think I'll upload the search page (it will do nothing) but at least to see and receive feedback on that.
Thanks savvy woman for the ideas!!!
Also What do you think are good ways to discover if a property has been sold ?.
User feedback, requring update....
Thanks again !!
