Do low ball offers on real estate really work?

Generally, the banks set a price on properties too high because they are in the business of lending money, not real estate, and as a result often they do not have a good understanding of the real estate market. Also, most banks are large, they have specific policies on reducing the price on a house based on how long it has been on the market.

Why foreclosures are not marketed hard in some areas?

Let’s say you are looking at a REO for which they want 25k and they have just come down from 29k. The bank apparently did not really look at the property because it isn’t worth the asking price. The only good part of the house is the structure; the house would have to be gutted to rehab. You don’t want to do it yourself but you would buy it to flip if your low ball offer on it got accepted.
