20 year old tenant, 0 credit score

[Jack B.]

They are all 19-20  year olds (3 room mates). First one's results came back, all clear everything, no criminal, evictions, etc. Credit score: 0....

They've all lived with their parents up to this point....

I don't think it's a big deal, when I was their age I also had zero credit. I now have 831. They probably have no credit cards or anything yet.

This would be a judgement call on your end. You can have their parents co-sign as a precaution or simply tell them you require a credit score of "x" amount and not consider them.
