Any lender will want to verify you will be able to pay the mortgage and the other expenses. So some kind of income will be needed unless you buy a property all cash.
You need to get a job to show income for lenders since you need to have income to qualify for a residential loan. Then I would get out of Los Angeles, ideally CA, and try to find a 4-plex to help off set living costs. I suggest moving to a landlord friendly state.
