The current list is1 Rent price range2 Purchase price 3 Number of houses on the market4 Population Growth5 Household income and growth6 Market appreciationI feel these numbers will help me get through the large bulk of cities. 

Common standards are something like credit over 650, responsible credit history, verifiable household income 3X rent and two landlord references.

I did some digging and found a research paper from 2015 that gave these stats:"The Canal neighborhood is a dense, Latin American ethnic enclave in San Rafael, CA where most households are low-income (a quarter of families fall below the poverty level) and 71% of residents have only a high school degree or less.

This decision will not come lightly, but we need to supplement or fix our payment process without increasing our monthly operating expenses.We also need options with credentials.Does anyone else struggle with this?

If the deal still works at the worst rate possible, it's a green light. 

The one downside to this arrangement is the tracking of expenses because so many household & otherwise personal expenses become split expenses: the landscape gardening, the cleaning of house & rental unit if single payment, the utilities, your tax accountant, homeowner's insurance, umbrella insurance, real estate taxes etc.

So happy to hear you found what lights you up!

There are a ton of considerations for this option that are beyond the scope of a simple online post, but I will say tread lightly and really think about this option. 

Example, new light fixtures and new sink faucets, vanities, and toilets.

Make sure if you see anything that is a tenant repair (light bulbs, holes in back of door knobs, light or outlet covers missing, missing shelving in refrigerators, etc,) you send a written letter to the tenant and also the section 8 case manager detailing what the tenant is responsible to do within 30 days of compliance.
