First, let me say that focusing your search on strictly "foreclosed" homes can limit your options greatly. Also, because a home is a foreclosure doesn't necessarily mean it is a good value. Many foreclosures that I see in our market are over prices...Why? Because as the RE market recovers lenders focus on getting as much for their listings as possible. I'm working with one right now that the lender/seller didn't disclose that the property had been condemned. You can only imaging the mess that has evolved.
Remember, in many cases these home have been abandoned and neglected and may be hiding HUGE problems that will surface down the road. Regardless of what type of purchase you make always be sure to exercise your options and have your property well inspected.
How can you see these properties....well, any local real estate professional can accomplish this but you will benefit from working with someone that knows this market and places your well being ahead of their need for a sale. IMO the best "foreclosure" agents are those that have the ability to share and explain things as they see them.....regardless!
