So are we’re talking about a single contract shared between multiple people or individual contracts with the landlord?
If it’s a single contract than whose name is the lease in?
If it were me and I could pay money to be rid of a violent person I would spend it and move. But the landlord would know why I was moving and I would point out that other tenants with the same desire for safety would react the same way.
On a financially related note, when I was first starting out in life I bought a used mobile home because it was cheaper than an apartment from day one. It means you have to qualify for something akin to a small car loan but from a payment standpoint it saved me money from day one over a traditional appartment. I then used the money I saved plus the sale of the mobile home as a down payment for a house. If that leap is too expensive then “house hop” by buying a nicer mobile home and then a nicer one (always used) until you are in a position to buy a home or you’ve found a mobile home that you could retire in. There are retirement communities like that.
You get the best bang for the buck in your living arrangements. You can also become a landlord and lease one of the rooms in your mobile home which puts you in the drivers seat with who you live with. You make the rules and they can as strict as NO COHABITATION at all. All romance to be taken off premises. That means only one occupant per room and no exceptions. It may take some time but there’s got to be a morally upright single person out there down on his luck who would LOVE to pay your rent. When I was struggling between jobs I worked at places that had all kinds of single people who got kicked to the curb because of the economy.
