It was too easy to make money in STRs and MTRs over the last several years but as we return to a more normal environment that's no longer the case.

Ok @Bruce Woodruff, everyone's gonna find out just how savage I can be, which I wouldn't normally share but you asked and it seems the most expedient and fitting the situation. 

Then you can make an educated decision about if this cost is needed and within the normal costs for your area.

If the heat isn't above the legally required temperature they might declare the unit uninhabitable and boot the tenant out until the situation is rectified (which will of course be a day later when they can come back and verify the temperature is back to normal).

I "openly and honestly" in much detail share with chapter long emails (Which I normally never do) what I learnt from the great @Chris Clothier.

Normally, you have to live in your home for 2 out of the last 5 years to get this tax break.

It's a bit of a weird situation for me to even be in as it's more of a 'living situation' house for us and not an investment in the traditional sense that I normally think of purchases as so it's been weird / impossible to take of the investor hat even during a much different type of transaction.

and we get rent paid on time as the tenants pick the fruit for food and use cash to pay rent. we have the normal mow and blow pick up any thing else.

The chances of a housemate wanting to leave mid-lease are higher in a house hack than a normal rental.
