It is pre-existing to my tenants and they appear to be clean people. 

He does outsource almost all labor (cleaning, mowing, shoveling, trades work). 

If the smoke smell is bad, you should probably wash everything down first, clean the carpets, and then use the ozone generator.These work great on odors from pets, food, or smoke, but it sometimes still requires heavy cleaning first.

I had visited their parents house when signing the lease (younger couple) in an A+ neighborhood and very clean. 

My wife use to clean rooms at a hotel before we got married and my mother and I were very poor and she was in bad health.

A disaster cleaning company came out and stripped the basement to the studs and tore the floors and some sheet rock off main level.

He is a hoarder & hasn't even started to clean anything up or to pack anything yet.

Great tenants didn't want to live in a neglected property but when cleaned up want to live in this neighborhood.

I have just got the place cleaned out and repainted.

Even with this disconnect on the purchase price, I am still excited about the property because it will help clean up the neighborhood as well as should be profitable even with extensive repairs.
