Messy housekeepers killed the deal

I received an offer from an investor for a duplex that I have listed in Richmond, CA. The numbers are excellent, especially for the San Francisco Bay Area. The list price is $199,900 and the rents are $2850/mo. When the potential buyer did an interior inspection, though, both sides of the duplex were messy -- unmade beds, clothing on the floor, stuff scattered about the back yard, etc. After viewing it, the buyer decided not to go ahead with the purchase. So, it's back on the market, looking for an investor that can see past the messy housekeepers!
