Bed bugs travel in furniture and clothes. 

With short-term rentals, you are responsible for those things but also things like pool care, lawn care, pest control, electrical, cable, furniture maintenance, dishes/towels/utensils/etc, cleanings, (you see where i'm going with this), essentially you are operating a hotel. 

Seeing as how we lived here a few years I feel like I know how it feels with furniture (and I’m pretty minimalist).

We also own a photography studio/vintage furniture rental business.

For example, I’m in negotiations with a seller for a house right now and if we hit an impasse, I plan to meet her price but ask her to leave all the furniture (it’s for an Airbnb property so I need furniture and I know she is going to move in with her daughter so she doesn’t need furniture).

I’ve been reading a lot about rolling up closing costs, as well as costs of new furniture into my mortgage.

Primarily I build custom furniture, as far as the home improvement side: general home repair (doors, drywall, paint etc).  

I only have leather like living room furniture as well, less penetrating material, easier to sterilize and clean.

You really need tenants with nice furniture that live clean and are very cooperative.
