The (formerly) nice wooden floors were soaked with cat urine and the place smelled exactly as you would expect it to. 

Some of the best tenants can come with the building even if the previous landlords criteria is a warm body they do luck out  as mine did. 

Furthermore, if the issue is vacancy, they claimed that the property would be protected while vacant (up to 6 months).So yes, I agree if the recipe calls for apples, I shouldn't use a watermelon, but what if watermelon just coincidentally in their dialect happens to look, taste, smell and bake just like an apple...it just happens to be twice as large for the same price?

Yes, there are obvious soil stains, the entire house has a very strong smell as well.  

There is a big article in a local paper where a highly successful body shop is doing just that.

What can be moved are the warm bodies occupying residential units.

If I were to keep the upper floor residential is there any way for me to insulate well enough to prevent noise (and smells) from circulating between floors?

If insurance is required the security agreement will recite the matter and if in the body of any note, the insurance assigned should be at the option of the lender for the application of loss proceeds.

Hey @Carolyn Martin - If I were just starting again, I'd probably look for a duplex that needed a little bit of work (paint/carpet/smells.)  

The smell from the urine soaked right into the flooring, drywall, everything.
