But with the VRBO renters, it doesn't appear that I have that sort of flexibility to write in the utility contingency.I'm considering putting in a NEST thermostat in the house and a remote pool pump monitor so I can keep an eye on where renters have set the temps?  

Why would someone leave a window open in 0 degree temps long enough to freeze pipes?

We already did temp fix for 4k which didn't help.

Craigslist has the temp and sublet section 

In Florida the AC is running 49 weeks out of the year and for the majority of the time you’re home and want the temp to be comfortable.

Tenants would then pay for whatever temp above 50 they like to live at.

Interest is deductible and hopefully the HELOC money is a temp solution with a cash out refi on the new property being a long term solution.  

Its going to open a lot of new doors for me) but I'm having trouble coordinating the temp power pole.Here's my understanding. 

Within a few hours you can be downhill skiing in the winter or at the California beaches playing in the surf.A lot of high tech is opening shop in Tempe and Chandler (near Phoenix) and housing is more affordable than other successful cities.

I'd be pretty upset if I had to pay the power bill for someone trying to keep the temp at 68 degrees 24/7 with the windows open when it is 100+ degrees outside.
