It is extremely critical that you have the right information and good resources for insights into the REO industry. I for one am a big fan of one of a particular author's sayings: "Know everything about what you are doing". Two resources truly stand out for me: DS News is the REO industry's resource for industry events and information that's of high interest to every REO broker. Each year they publish their famous "Red Book" that highlights the major financial institution players in the business.
RealtyTrac is the number one provider of accurate real estate and REO statistics. This is THE best place to get data feeds, widgets and foreclosure article RSS feeds to dress up your website and make it "buyer sticky". The Foreclosure Trends subscription is the real "hook" for investors. Get it here.
