This leads to the number of households created. 

Limit an initial conversation or questionnaire to no more than 3 to 5 questions:What is total household gross income?

If it were me I'd fix it up to rental quality, no furnishings and rent to the first qualified tenant to apply (3 x the rent gross household income, no history of court with or debt to prior landlords). 

You may not include income earned that is not on a tax return, an administrator or PHA may consider additional income in that household, a teenager may mow lawns or receive child support that may influence funds available to that household. 

Let me give the type of scenario I'm envisioning:A Homeowners Association negotiates with a home/property insurance company to get a discounted deal for members (households in the association/neighborhood).Questions:1.

I spent $37,000 on furniture and household good (high end condo), and received $8,000 when I sold the furnishing after 6 years.

Census data - median household income, employment stats, bachelors degree percentages, crime, vacancy rates, appreciation2.

The amount of rent is based on the AMI which can be found here in this handy chart:https://www.sandiegocounty.gov/sdhcd/rental-assistance/income-limits-ami/so the calculation looks like this:For a 1BR unit (2 person household) at the very low income level you could charge a max of 1/12 of 30% of $48,500 or $1,212.5 per month.Also, in the agreement that I've seen (which was for a different City in CA) there were some restrictions against students.

There actually is this weird scenario, just past goldilocks, and closer to Alice in Wonderland, where the economy keeps chugging along…. slowly, household incomes crawl ahead, corporate earnings play duck duck goose, unemployment (usually) rises and inflation stagnates.
