I can try to help you, but often if you are looking at something like realtytrac or trulia and there is no specific address, they are not really for sale. Also they often post the wrong prices. What they post is called NOD or notice of default. It's what happens when you miss a payment. That borrower could catch up and the house never go to foreclosure. If it does it could be a year or two before the foreclosure happens. Then it might be another year or two before the house goes on the market.
The reason I say the prices are often wrong as sometimes what gets posted is a second mortgage or back taxes....so if you see a price that just seems way too good to be true, normally it is.
Shoot me the information you have and I can try to research. Also I can send you a list of the foreclosures we currently have on the market in the area you want to live.
I also say look at everything on the market, not just the foreclosures. Sometimes you'll find better deals on regular resales or houses that are in much better condition.
