I recommend you look at Westchester area (Los Angeles 90045) for a rental situation there. Many of the students will lease together and share expenses. The neighborhood is accustomed to this and there are homes with 4-5 bedrooms in the area. Most of the students do have a co-signer on the lease, so they will expect that from you. Normally it is a parent, but perhaps you have another relative who would do it for you.
Find a roommate to go in with you or find a home with an assisted living facility. If you go in with a roommate or two you all will split all household responsibilities. With assisted living utilities are included but the place may be smaller.
