Sorry.. its been a long week!
There are a couple of excellent websites:
One is Countrywide Foreclosure Blog - this lists all the REO properties by bank/lending institution. http://countrywide-foreclosures.blogspot.com/
The other is GMAC's REO listings: http://www.fsr-gmac.com/en/reolistp.asp?a=8
If you should need any help in viewing homes, presenting paperwork, or negotiating with the banks, I'd be delighted to help!
Have a great weekend! Best of luck with the lists!
