The politicians are crying big crocodile tears about the poor people who can't find "reasonable" rents in one of the most desirable cities in America. Is Bakersfield having a housing shortage? The real question is what would the per person rent be for a 2/1 house with three people living in it, in the same neighborhood? A thousand a piece? Fifteen hundred? Twenty Five hundred? Who knows? I'm guessing it's not $600-$800 (depending on utilities included).
You would only want to rent by the bed or bedroom in a beater house. One that condition isn't very important. We all know the famous phrases "beat it like a rented mule" and "I can do anything I want as long as I pay the rent". You would not want to do this with a "pretty house". Just assume all rooms are double occupancy (although this proves that it could be more). The second someone gets away with saying they are single usage, the boyfriend/girlfriend will immediately move in. As a matter of fact Bobbies girlfriend will move in, Bobby will move out, New boyfriend will move in. Both will move out, but they have two friends to move in. You'll never keep track of it.
It helps to have a resident House Master sympathetic to the landlord, and getting a break on rent, to keep things in line in real time. Boots on the ground. In college this was called a Resident Assistant. No "the landlord will never know". Get one of those (first born?) people who think they have the right and duty to run other people's lives. Security deposits are a huge problem. Dan moves out and gets his $1,000 security deposit back from his friend who moves in. He moves out and get the security deposit back from the new guy. You evict everybody and keep all the security deposits because there is way more than that in damages. Everybody screams at the same time that Bobby, Suzie, Ken and Jill did the damage. Not Me!!!!!!!!!!! Here's their phone number/address/relative/employer. You smile and tell them, that's nice, you can collect the damages you are paying from them.
