I stumbled on this site that I thought was pretty helpful. It contains a list of MLS feeds that individuals can search for property sometimes even by maps.

They also had a few interesting articles such as
The "Loan To Value" Rate Applications in Commercial Real Estate
http://azhomevaluesat.com/realestat...ent/view/76/28/
and several others at http://realestate.azhomevaluesat.com/

Looking for more good articles similar to these and http://www.creonline.com/

Thanks for the helpful links. It is great when you have a reliable link for listings. I have found that some sites are not as useful as they first seem.

I agree with lcsamano. I feel like I've read so much useless info sometimes THINKING that it was going to be helpful. It's nice to see people sharing their favorite sites that actually have good info on them.
