A 2 story w/basement 4 bed 2 bath is not going for $100k in 2010. Doesn't matter how shitty. That was the writers trying to pull a fast one. That is easily 150k-200k. If it's a good neighborhood (meaning safe, homogenous cultural understanding), 200k is more spot on.
In my midwest town, unless that was built 100 years ago, no way it's being less than that. Doesn't even matter if it was lead paint or vinyl siding. That home homer lived in was the exception, by far the rule.
