My first suggestion is to start by reading over the blog archive here on REOPro. Many of our agent have written excellent blogs on how to start doing your first REO, myself included. For example, here are some blogs in my archives....
My point is, the information you are requesting is already out there on our site. You just got to go sniff it out. Do a blog search and type in some keywords then scroll through and find a topic that you want to read. Before you know it, you will have so much information your eye balls will pop out.
By the way, don't forget, if you are looking for companies to sign up with, click the partners tab...it's all right there.
