You can sell retail, the buyer gets a bank loan, has it rehabed then refinances the temp. loan with the "end loan".

The temp agency I use has the duty of checking documentation, and I tell the owner "If I make the news, so will you".

It was below freeze temps. 

The room temperature is always below the thermostat temp by 2 degree.

Something to consider is that you would have to increase the rent to offset your cost for paying for gas and how much would it cost to set this up and will the tenants be able to control their temp.

I see the City has a Temp occupancy Tax (TOT) of 10%  for renters less than 31 days...not sure if others have found these type of ordinances "writing on the wall" regarding a change in attitude towards rental properties.   

WE have a number of contractor friends & they are always at the mercy of their subs & temps but their reputation is what ultimately suffers. 

Me, I'd be temped to let my mother  take over, and she would go in a completely different direction.  

No mention of the STR in Paradise Valley, AZ used for shooting porn flicks or the gang shootouts in Phoenix, Scottsdale, Tempe & Mesa STRs?

an underground heat exchanger (constant temp underground) would be way too expensive to build and not even advisable in Astoria. gas is a much cheaper alternative to electric here in NYC.
