By the way: $2,000 as a purchase price? I agree with Deborah; highly unlikely. Buyer beware!!!
I have a feeling what you are looking at is monthly rental rates. The process for foreclosures is to get listings from a Realtor you trust. The MLS has everything, from REO (real estate owned), short sales (a seller who owes more than the house is worth and thus needs lender approval), pre-foreclosure (see short sale), etc. If you have anymore questions, please fire away! Good luck.
It is highly unlikely that you would ever be able to purchase a property for $2000. Where you might here of something along those lines has to do w/ tax sale certificates. Investors purchase tax sale certicates by paying back taxes, and the homeowner has a period of time (varies by geography) to pay the investor the tax amount he/she paid plus the interest. If such is not done, the investor could take title to the property. This is rare. Most investors purchase tax sale certificates for the interest monies earned. You can see late night TV programs that promote the purchase of homes for back taxes for very low amounts. It can be misleading.
