I agree with most of the answers below.
Here's a link to some Pre Foreclosed properties and REO's (Bank Owned).
And, by the way, you don't want to invest in a condo as most of the condo's out here are condo conversions, sold by builders who did not leave enough reserves for repairs. Many of those have 30% and more of the owners that do not pay the dues any more. Special assessments galore!
Have Fun & Good Luck
Just curious, what makes you believe that buying directly from the owner will benefit you? Just as a suggestion, I would recommend interviewing a couple of Realtors, compare their proposals, then see if in fact it would not make sense for you in the long run to have professional representation.
Wouldn't it be a shame to learn that you paid too much for a home?
