Would you let the property ,if the tenant hasn't got the address proof

Other

Hi ,I have a foreign couple interested to rent my place, they are sharing a room with their friends, they haven't got any address proof whatsoever not even a proper bank account. Miss has her wages paid in prepaid mastercard, i checked the account,she gets money paid by boss ,boss also confirmed that. but those kind of account doesn't have address on it.and Mr is using brother's account,his boss also confirmed that money goes in that. and i checked the statements too, but the point is , it is not his account. credit score with rla ,for Mr is 125,
and for Miss is 85, and no residency confirm by rla credit score, would you let it this couple or i am inviting a trouble here,

thanks,
Binita
