Would you take this tenant who falls short of the income mark?

[Johann Jells]

Got an app for an apartment today that didn't make enough, but here's the deal. rent is $1650, x36 (1/3 income for rent) is $59,400 required income. He just started a Federal job at GS-7: $47,374, and will make GS-9, $57,948 in one year.   He said he's been living with family since graduating college with an engineering degree (he's 24) and has socked away savings, I failed to ask how much. 

My nose says yes he'll be fine, but numbers don't. Should I ask for his bank statements? Is that legal? What is not legal in NJ is any form of required prepayment in excess of 1.5 months security.
