I have been inside of their unit several times and they are not the cleanest tenants--often finding food, crumbs, dirty dishes, trash etc just laying around the house.

You could also be upfront with them and tell them that this is how you put food on the table, so you're going to make a profit off this deal.

Travel nurses are given a specific per diem for their food and shelter. 

McDonald's dominates market share in fast-food, do we make that "public domain"?

Here's the thing, property management will place a qualified tenant, but you would place someone you can get along with.With a cell phone you can easily get a repair done by someone and not pay a markup for the phone call.Just food for thought.

The ONLY reason that I am reciving the cash assistance is because I was Homeless for 8 months (1-18 to 8-18) and had zero income, and with the acception of food stamps, I was slipping through the cracks of everything I applied for through the county.

If someone is in a situation where they need to chose which bills are the most important to pay, they will automatically default to the basic human needs food, clothing, and believe it or not, yes they will generally pay for shelter too.

Rodents will always choose a comfortable indoor space with a food and water source.
