;)Be careful there, building codes today might not permit that to be done.  

We have experience in a lot of lower-income types of properties (specifically 32839 and 32808 zip codes).  

An extension cord going from the residential building to a motor home parked on the property would be a municipal code violation in our town.

Ie zip codes, household income, age. 

Not around here, unless it meets code for a bedroom, etc.

This is fine because I can bring everything up to code and get the work done cheap.I don't imagine that the previous owner would ever come back but I want to be on the safe side. 

I'm pretty sure that section of the code are regulations for Division of Insurance.  

If not just get a renovation plan together with your construction team and go to the Building Dept. in the town the house is in and tell the building/code official of your desire to renovate the home to a safe and livable condition and obtain the building permit applications to start the project once you close.Fannie Mae for me has allowed 7 day inspections although they have never renegotiated a price.

Our latest tactic was to call code enforcement for the numerous code violations, but that is temporary not a permanent fix either.

Depending on the city ordinances, and the code compliance division there, it could become rather costly.
