I am going to show you a few sites around the internet you may or may not have heard of.

The first site is http://www.truilia.com in this site you can post and read questions and give answers about just about anything to do with real estate. You can search listings and make alot of new real estate contacts.

The second site is http://www.activerain.com this site is also similar to truilia you can make alot of contacts if your an agent or in any real estate field. They even allow you to post a blog as a profile to your real estate business for free.

the third is http://www.zillow.com this is the largest of the three at least i believe it to be. You can make alot of contacts in real estate or just search listings for free.

The fourth one is http://www.propertyqube.com/ it has a similar format as the rest and you can ask questions about real estate and maybe get some free expert help!

I will be adding any more that i can find out there. As many real estate sites as i can find for you. So bookmark this page for future reference.

maybe you already know about these sites but if you dont then i hope they help you with all of your real estate needs
