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...

Some elements that will make a condo non-warrantable are:* High investor ratio* Insufficient reserves/Bad financials* Litigation* Buying as investment vs primary/2ndWhen the condo is deemed non-warrantable for the specific transaction, then the only financing option left is a non-warrantable condo portfolio loan.Hope this helps.

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. 

All other work-foundation, framing, drywall, texture, finish-should be done by a professional.There are many different kinds of laborers that you can hire-licensed general contractors, licensed contractors for specific elements of the building process, skilled craftsmen, and laborers.

Is this a boiler building where owner pays heat?

There are certainly going to be some tried and true elements, but we believe as technology, culture, etc. change that so may business structures and practices.With all of that said, as brokers and agents, what service, support, and features are most valuable and most attractive to you in where you choose to do business?

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.
