I have lots of RE clients and I have not put one into MODx yet (because they predate my coming to MODx in 2006) but it would be easy as pie. You just need to create TVs for the fields/features and you can have them fill in the blanks. The you can display them using Ditto, use AJAX Search to allow queries and more. You can even create XML feeds with ditto and email newsletters with TEMailer and Ditto.
I am actually going to be developing a RE site with MODx and using
Viele RETS to pull the MLS data directly off the MLS server for a brokerage but for an agent, I would just recommend doing the TVs. RETS is the
Real Estate Transaction Standard developed by the National Association of Realtors
If you have never worked in RE before you might want to download and install
OpenRealty to see what fields to use. Personally I don’t like OR as it is clumsy and requires many oddball scripts to interact with the core.
When 0.9.7 comes out I may build out a whole solution for MODx for REs. and Brokers as an alternative to OR.
Let me know if you have any specific questions on building out a site.
Cheers,
Jay
