I am wondering if the 3x the rent income rule applies to the entire household or each individual tenant. I have 3 friends/roommates looking to move into one of my units and 2 of them make 4x their portion of rent but one only makes 2x her portion of rent as she is a student finishing up school.
I am worried about that single roommate not being able to truly afford the place.
Assuming they are joint obligated, it is generally the total income of the people signing the lease. So if the rent is $1,000 per month and landlord is using a 3x, then they need jointly to be making $3,000 (it sounds like they more then cover).
How they split it up between themselves is between them; perhaps the lower income person / lesser contributor gets the smallest bedroom?
