Poly-rental
When 3 or more people live together as a family, (not blood related, closer then roomates) yet not fully dating. Can not just randomly move out when you want like a roommate, would have to find a suitable poly-partner to take over.
This rent is so high, will need to have a poly-rental just to live here comfortably.
This house is 5x more then what I can make, good thing I have a poly-rental relationship.
