Can you show us examples of such homes for sale?
Here's a real quick report on properties in one zip code that have sold since Jan 1st of this year. I'm sure there were more but this is just as a quick grab.

Property #2 was sold in 2004 @ $150k.
#4 #5 #6 #7 didn't need any repairs. #8 was two detached working houses (people were living in them at the time of sale) for $25,000.
Where is this Circleville Ohio?
Not just there, most of my county & surrounding counties are like this.
