Thanks for the great information!

I can share that contact information with you if you like

I'm not sure how anyone could even answer your question without more information.

I am curious about building a RE website and the best way.I've had some people tell me that it's best to have two: one for motivated sellers (a "we buy houses" type that basically just brings in leads) and one for buyers and general RE information.

This is a good place to start as they have the more experienced staff there and you don't have to have such a defined idea of what you want.They will look up these tools amongst other things (these tools are awesome btw):http://zimas.lacity.org/http://navigatela.lacity.org/navigatela/There you'll get a load of information from zoning to issues related to the property to details of the property to services in the area, whether it's a landslide zone, hydrants, sewer, RSO, Ellis Act and much more.

It also tracks your expenses and income, either by snapping a picture of a receipt or by linking your bank information/credit cards and importing the data.
