How to combine multiple-adults' background checks

[Malik R.]

With multiple adults in a household, each person applies with their background check run individually and some screening companies provide a general assessment of whether a person has a high probability of success as a renter. 

For example, the applicant makes $2,500/month, GF gets $1,500 pension and her 23-year-old son makes $1,000. Individually each is assessed at higher risk as a tenant but together they make the 3 times rental income. If any of them leaves, the rest won't meet the minimum income criteria.

How does one develop a joint analysis of the family unit?
