It sucks but this is what I would do.If you have no money invested in it, I would tell the seller,  that I totally understand, and although the contract is signed, I would tear it up and best of luck.And go find a new deal.They are people too, honest, dishonest, doesn't matter.

UNLESS of course your talking about a sub set of say Class A condo's where HOA does everything exterior and tenants live as neat as you do. ( or I think you do :) )  But in the Class C B or D your just going to take a lot of wear and tear from tenants its a given.
