I like using these for just this case.Another item to consider is since this is a 2nd floor I wouldn't be that worried since the 1st floor will heat the 2nd floor enough to not allow frozen pipes.I would also talk to an HVAC person because I believe they can also put a device to cycle the heat a few times a day or even put a secondary thermostat in the apt to take care of the minimum issues.I feel for you because otherwise you have a great tenant.

I have no doubt you’ll continue to achieve great success in your investment journey.

I highly recommend going to meetups and talking to investors in person. 

I hope bookings continue well for you

Talk to property managers and see if they would manage the other units.

I talk to a LOT of out of state investors looking near my hometown in the Akron/Canton area, as well as places like Cleveland, Toledo, Dayton, Columbus and Cincinnati.

You should to talk to @Andrew Postell He is the best mortgage guy for this.

I would be happy to talk with you about the real estate market and what your goals are in investing.

My vote is if you are going to continue to buy, you need to utilize leverage.

@Gabe Goudreau how big of a deal are we talking about here?
