Hi all , I have this place in Arlington Texas . A girl want to apply . She seems very nice . Work at restaurant Make about 2300 to 2400 per month . Only want to stay for one year . However here is th catch, her credit score is on the 600 ish. Had a lot late payment that happens more than 7 years ago ( according to her I can’t tell. Credit report just show over 3 years) All the current one is onTime . She say her fincial advisor tell her do not pay it off for the anything in the past ( why? IDK) She say she rent a room from a family now and she is not happy there because place is not a very nice place. Haven’t call for reference yet. But wondering if I should reject her or call for reference from current and previous landloard . Thanks
