3 times the rent vs. Good credit score

[Sami Gren]

Hi, I am renting out a 2 bedroom apartment for $1,200 I had two people looking at it, one person was an older mother not working with her daughter working that makes three times the rent net, but she does not have now the full amount to move in including the security deposit and her credit score is in 500 due to medics bills and a few other stuff, versus the second person makes a little under two times the rent but she has a great credit score at 6 70 and she has the full amount to move in right now, what would you do?
