Application Fees: run and charge for both adults?

[Lisa L Day]

Hi community!

I'm starting my first ever round of applicants for my first door.  If 2 adults are applying (not married), do I run background/credit checks on both adults?  If so, do I charge the $38 (RentPrep smart move) PER applicant, that then goes toward their security deposit?

Does your opinion on the matter change if it is a married couple applying together?

Thank you for your opinions and insights!
