Bankruptcy on one applicant?

[Melissa Stanley]

I am renting a single family home and found an unmarried couple who is incredibly interested. One applicant makes 3x rent and has a 792 credit score. The other applicant had a bankruptcy in 2021 and has active trade lines (I can’t see the detail on when these went into collections). 

I intended to write the lease to hold both financially responsible regardless of occupancy (effectively making her a co-signer), but I’m worried that I’ll end up evicting him if she ever does move. 

Overthinking it? They are otherwise ideal applicants.
