Do you ask for credit/background check for...?

[Carmen Chow]

Hoping to get some advice on fellow BP members.

I’m planning to rent out a unit for a family of 4. Mom, 2 sons of working age and a 17 yo daughter in school. The combined monthly income for the mom and the 2 sons are about 3.5x the rent. Credit/ background check for the mom is cleared and she has minimal debt (mom paid a total of $40 on cozy screening).

My question is, would you also advise doing a credit/background check for the 2 sons as well? And who should be responsible for the fee?
