Screening tenants advice

[Amy Zhang]

I have an apartment to rent and am going through screening process. Mom and son will be living in the apartment and kids will be there on the weekend... son income alone does not qualify but his half brother who own restaurant nearby is willing to be on the lease..son works at the restaurant as well.. combined son and half brother income will qualify... should I be worried about that since half brother will not be living in the apartment and even though he will be on the lease? I am worried son cannot pay rent...

Thanks for advice
