Want to know how to stop Foreclosure ?????
The easy way: go to stop foreclosure : http://www.tostopforeclosure.com

Those are REOs.

For pre-foreclosure, there are several ways. They include, note buying, short sales, and providing services to those at risks of foreclosure. As to how to do each, that's a bigger lesson than I can post here. You are better off learning which ever method you wish to work with.

I run a real estate seminar list. You might find one that suits you.

Also, be aware that foreclosure investing is also rehab investing. You will rarely find a foreclosure that doesn't need, at least minor rehab. Especially in today's market when buyers are looking for upgrades.
