You might want to give it a try Phiroum. I've seen several of these classes, and even property tours, down here without much result though. The fact is, you need access to listing information that is not widely available in the MLS. MLS listings of bank owned properties are straight forward. It doesn't take any special knowledge to buy them and the investors and buyers know that. You should subscribe to RealyTrac and then you'll have something different to pitch. They also have good instructions for buying bank owned and pre-foreclosure homes on their website http://-www.realtytrac.com.
You could use these as your course outline. You can get a free 7-day trial membership and take a look for yourself. Be careful though. I had trouble sleeping when I saw how many foreclosures were coming up in Puyallup. Good Luck!
