No income, no asset (NINA) is a term used in the United States mortgage industry to describe one of many documentation types which lenders may allow when underwriting a mortgage. A loan issued under such circumstances may be referred to as a NINA loan or NINJA loan. NINA programs are ostensibly created for those with hard to verify incomes (waiters, etc.) but in actuality have been popularly used in situations where aggressive mortgage lenders and brokers did not want any trouble qualifying otherwise non-qualifying loans, thus becoming a significant factor in the subprime lending crisis.
