Last guy on reddit was unemployed at 29 and living on his sisters couch after losing his minimum wage job...so of course he had to attack me with a nonsensical post like yours that doesn't actually bring any value or answer my question...I'm considering doing this with a few of my houses that have enough equity.

No normal person will rent a couch in the living room of a shared occupant house.
