A Balloon-Payment QM must have a term of 60 months or longer.(12 CFR 1026.43(f)(1)(iv)). A balloon loan with a term of 36 months is generally not allowed under the Ability-to-Pay rules. The loan would be allowed only if the debt to income ratio, calculated using the full balloon payment divided by the consumer’s monthly income, meets the standard set by your bank. If the loan amount is $100,000 and the borrower’s monthly income is $5,000, the debt-to-income ratio would be 2,000%. Your standard is probably in the range of 40%.
