My contractor has gotten impatient waiting for him and has started taking matters into his own hands (he did the jack hammering of the floors which my plumber said had "complications" and would "take forever to get through"). 

Some need new furnaces, flooring, and paint.

For rentals, would a single floor or two floors makes sense? 

I want to refurbish the entire house, including a complete kitchen and baths renovation, add an addition on the east side, new roof and siding, new flooring everywhere, paint inside and out"Then ask the GC to go over and put this into a more formal document.
