I knew the deal was in trouble when the property inspector with the mold detector dogs would not bring his dogs in the house because he was afraid the dogs would catch something from all the cock roaches.   It was advertised as a cosmetic fixer, but this unit was really in need of reconstructive surgery.  The place was filthy, in need of updated kitchen and baths, and everything else.  My buyers were willing to accept all of that.  But when we got to the mold and roaches, it was just way too much to accept.   

This is an example of why a property inspection by a professional is so important.  Yes, this is an extreme case.  And, yes, this really did happen.  But it proves a good point.  Buyers often do not want to spend the $300 or $400 for a home inspection, but it is money well spent.  There is no guarantee that the inpsector will find everything that needs repair and no guarantee that nothing will break soon, but it still gives buyers a good idea of the condition of the property they are purchasing.   I like to compare it to getting a physical.  While the doctor may not find everything wrong, you will be warned about things you may not be aware you have, such as poor cholesterol and high blood pressure.
