Your best bet is to work with a realtor, it wont cost you anything, and you will have some one representing your interest, and you can ask them all the questions you want.
One important thought considering buying foreclosed property, it may have a lot of damage and the savings that may be there on the price you might have to spend a lot of $$ fixing it up wipping out those savings, or it may have other damage or maybe even a sinkhole problem costing 10s of thousands of $$ to fix.

Dont just shop price alone.
And make sure you can get insurance for the property, do it soon..
