Dirty Homes For Sale

Is it me are do you find dirty homes hard to sell? I recognize that with so many homes "priced to sell" by the banks that not a lot of work goes into "sprucing" them up. However, if I work hard to get a listing I want that property to sell.

Do any of you do  little clean up on a vacant house that you list or is it "buy as is?" I can understand if that is how someone wants it sold but if so, shouldn't that fact be listed in the MLS information?

I took a buyer into a bank owned home yesterday and the description on the listing did not reflect the true condition of the home. The buyers looked at it and were unhappy that they wasted time to view something that had misled them.

I'm curious as to why an agent would not list the true facts? Does anyone think that leaving out pertinent information or making the property something it is not will get a sale? Back to my second question, does anyone do a little clean up on a listing if it is a vacant property owned by the bank or an out-of-state owner?

Is it just me or does anyone else have a hard time selling a dirty home?
