@Kje Franks first I would take the electric out of your name and tell them they must switch it by x date.

We fixed some major safety issues like replacing the electrical panel and upgrading the railings on the deck.

Get in there and fix some frozen pipes, start with a hair dryer and graduate to a space heater, or (like I did) take your wife's favorite 'fancy' electric fireplace and drag it into the crawl space dirt to thaw the main floor P trap under their tub because you have no options and nothing is draining4.

Go to the basement and look at the electric wiring, look at the plumbing, and HBAC.

Amazon’s made a huge push into corporate hospitality over the last couple years and some of the custom workflows I’ve seen for creating guest FAQs that the devices can respond to without bugging me or requiring additional pages in a physical house manual are appealing, something like VCS or a custom-designed audio FAQ.

I have thought of starting by removing the old carpets, doors, cabinets, electrical fixtures.

Practical items to care for are: loose hardware particularly on chairs, tables, or stools, a fresh coat of paint on walls and baseboards, loose drawers, fumigation, bed frames, new linen, loose ceiling fans, functional electrical outlets.

Example:  Electrical, HVAC, Security system, Roads/Parking, etc. 

Already Metered both electricity and water.

I try to incentivise them as much as possible by offering the following: 1) One full year of rent in advance (typically at a slightly discounted price from their advertisement); 2) I am responsible for any maintenance items excluding major mechanical issues (electric and hvac), which means if there is any kind of backup or plumbing problem, it's on my dime, but it also means that they are going to have a renter that is not calling them to fix minor things; 3) I release them from any liability related to the Airbnb; 4) I install a keypad lock on the front door and agree to leave it when I vacate; 5) After the one year lease we go month-to-month until March when they can get back on the seasonal leasing schedule (which I inform them of), and then I sign a year lease and pay as a regular tenant.
