I started my professional career in medical device sales and still do that full-time.

We go above and beyond when it comes to protection.. starting with insurance coverage, sings in the listing and in the property that there is no guard on duty (as silly as that sounds), putting extra locking device high enough so youngsters can't reach, an alarm/beep system to alert them that door opens for those with small children (or elderly) so they cannot wander out in the backyard with no one noticing and risk drowning.

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.

My community is safe, and yard signs are a great way to advertise my business.

I'll keep you in mind if I device to pull the trigger.

My current situation is, in part, a result of playing it too safe and avoiding risk altogether.

However, it's a safe bet that these respective areas will continue to appreciate steadily for the reasons noted.

That is a safe harbor from the IRS with a couple of caveats. 

If you found a safe way to do lease options in Texas I’m all ears.

Be safe out there.
