In one particular circumstance we had the same tenant intentionally damage their heating system and then calling in a complaint. 

Upgrades include a fully remodeled kitchen, renovated bathrooms, new durable flooring, contemporary fixtures, and efficient heating and cooling systems.

Estimated cost for remaining changes (all new electric, drywall, tile, fixtures, cabinets, roof, doors, windows, heat pump, some siding, and fencing.

Installing thermostats with regulated heat control (we pay heat) 3.

Only heat.  

I was doing some research yesterday, a typical wildfire generates radiant heat of about 1,500F and with high winds can reach up to 2000F. 

The lease language requires the interior of the building to heat to 70 degrees.

The agreement is contingent upon the buyer securing financing which I was not able to do and have provided a denial letter.The seller is requesting money for damages because the appraisal came in at the purchase price but needed a heat installed in the kitchen which the seller agreed to install (Not in writing).

Give them enough pressure, heat, or attention and the charming melts right off and your left with the rotten core.

Not that I plan to live in or even visit the US anytime soon, but I don't want to deal with winter-related issues like heating, de-winterizing a home etc.
