I’m actually drawn to outdoor labor of some kind.

A little more expensive than outdoor or commercial carpet but its been lasting a long time like 20+ years in a 3 unit.

I would have had to add an outdoor living area coming off that back door.

I plan on taking down the dividing fence between the properties to create a communal space (fire pit, outdoor dining area) for the guest to enjoy which will also raise my airbnb price per night in all units.I can get a conventional loan to cover the renovation and the purchase price for 20% down (just over $110,000).

You do get that where they are clueless about outdoor maintenence, although I am not sure where they lived that they did not have to pay utilities.

During recession flooring materials, kitchen upgrade, high ceiling homes matters more than outdoor fire-pit, hot tubs as housing empirical data suggests in SFBA.The regression analysis can include more factors like schools (API), condition, parking (1 car, 2 car), neighborhood crime and the data are available. 

The previous tenant didn't like to be outdoors apparently. 

.- Set thermostat back to certain set temperature- Lock house and return the key to the lockbox (if needed)Any more than that and I think you quickly run into the "Well why am I paying for housekeeping services then?"

- If you are sharing Heat/Air with your tenant, how do you handle temperature adjustments?  

Since lead is a problem in older townhouses in Baltimore, I would either have to paint over the 2 story house to cover until potential lead paint(which is at the end of the street, so it has more outdoor surface than other townhouses).
