How do people deal with communal furniture in a house-hacking set-up? 

If your parents need $200 per child per month, is that something that all the siblings/children do??

It looked like a murder scene with bloody handprints and smears on the walls and furniture, blood all over the apartment.

Their cabinets are a step above their other furniture and you can't tell.

A strong removable wall was built to allow moving large furniture and appliances in and out.

Paid 5k, runs well, knew he took care of it etc...It was one of the best decisions I made.Not just picking up materials like everybody says cause I rarely do, but if you are in real estate and managing it It is just convenience for everything.Material left over, returns, small trash, furniture etc etc etcAs a rental investor, I would say if you have more than 6-7 unitsDont hesitate, buy a low priced, decent one, keep it, it will make sense.

From a liability standpoint, it's a good idea, but I think it can also help increase rental demand for tenants that may have pets, small children, etc.

Just expense everything (supplies, furniture, etc) that you spent money on in the 2020 calendar year. 

Killed the neighbors children’s cat crazy.

The first left some stuff behind, but it was just stuff (furniture, boxes of things).
