(edit: they are not my friends, just friends with each other. I know the title is misleading, I can't edit the title). They are mid twenties, apparently they are both new to their jobs and don't have 3 paystubs yet. They don't qualify on their own the 3x rent qualification or credit score (one of them has a credit score in the mid 600's, unknown what the other's score is) but they said both sets of parents will be cosigners. Never dealt with a cosigner before and seems risky. What's been your experience? Should I just hard no and avoid the risk and hassle? Edit to add some details: one of the applicants mom just called me to vouch for him and said that they will pay for his rent while he studies to become a pilot which he has 6 months studies left, then he would be making high income. She offered to pay 6 months rent for him or even a year's rent. She comes off like they are wealthy mentioning he has a trust fund . I know I'm getting a lot of people saying NO but does this change things?…
