for these two rental applicants, do you see any issue?

Two adult applicants: The 1^st Adult (credit score 645, past 3 years, 4 delinquencies, but do not know the detail) stated that they earn $8,000 a month and the 2^nd Adult (credit score 780) stated they earn $28,000 a month. Their income not verified yet but looking at the 2 paystubs the 2^nd Adult provided, they probably earn $16,000 a month.
