Depending on your needs, strengths and comfort-level of risk, there are several ways to find foreclosures.
1. You can visit the County Clerk's office and search for 'Notice of Default', 'Lis Pendens' or 'Notice of Sale' Or you can go to banks and introduce yourself to head of the REO (Real Estate Owned) Dept. The best part of this search is that it is free!
2. You can look online with a listing service, which is alot easier, but you definetly won't be the only one who knows about it.
3. Look in the newspaper as part of the requirement for filing a foreclosure is that the Notice be published.
4. If you will be financing your purchase, and would like to actually walk-thru the home before bidding, a realtor can help you find a foreclosure, but be prepared, you will probably need to pick up your hammer and nails!
