How do I find SAFE, affordable housing for my mother who lives in Northern Ohio (Lorain/Erie County, city of Vermilion)?

My mother is low income, only having Social Security, and is age 63. She is on SNAP. She lives alone and independently, but my sister lives in the same town and helps as much as she can, (I live in a different state), but it is too much care for my sister to provide (in the form of cash usually to my mother). Mom does not make enough money to support her basic needs, such as transportation costs for her car and other basic needs. Her apartment is awful and NOT safe (slashed tires, threatening neighbor) - I need to get her into a more safe and clean environment. Please give me any advice you may have for this particular area in Ohio. Thank you.
