If the home is stripped to the studs, and I personally do the work, wearing a P99 full face respirator along with full body disposable suit... the place is aired out, I give the chemicals time/heat to volatilize...

If i separate heat, can i ask protected tenants to start paying their heating bill?

If your putting a loan on the house then just make sure the big items like the roof, heating and air and windows are in good shape so that you dont have to replace them in a long time. 

Is this a boiler building where owner pays heat?

The discrepancy with this house is that it currently has 1 electric heating unit, and 2 gas heat.

Other downsides, heater is oil heat, and no central AC (just small window unit), large yard is very overgrown with Himalayan blackberry bushes, and no garage (converted garage to living room space).Upsides: decent condition wood flooring in bedrooms and about half of the living space area, newer vinyl windows in most of the house, outside siding in great shape, roof looks to be in good shape, and the most important upside is the neighborhood, excellent area.FinancialsThere are already multiple offers on the property and they are accepting offers until Monday morning.  

First and second floor are both 3/1, heated by the same oil furnace, third floor is a 2/1 with gas heat.

I contract out myself doors/carpet/ granite/ heating and cooling/ floor refinishing. 

With that said, I have a house off washington, that iv lived in for 3 years now, I am all in for around 1050 a month, my upstairs pays 1100, and for the first few years i had a roommate for 350, which covered heat and cable, so I was happy just living 100% for free, it wasnt worth packing another guy into a room and wrecking my quality of life for an ever 350 a month.
