Homebuyers and lenders need to consider not just income but also liabilities, such as student loans and auto debts, with recent guidance highlighting the importance of managing monthly obligations to improve mortgage approval chances.
When homebuyers think about mortgage approval, income is only half the picture. Lenders also review liabilities – the monthly debts that reduce how much room a borrower has to take on a housing payment. According to the guidance from Fannie Mae and other major lenders, those obligations are measured mainly through the debt-to-income ratio, or DTI, which compares total monthly debt with gross monthly income. Chase and Wells Fargo both note that a lower DTI generally makes approval more likely, while Fannie Mae says manually underwritten loans normally target a total DTI of 36%, though some borrowers may go higher under stronger credit and reserve profiles.
The key issue is not just what a borrower owes, but what monthly payment the lender must count. Credit cards, auto loans, student loans, leases, tax payment plans, child support and alimony can all affect the calculation, but different loan programmes treat them differently. That is why two applicants with similar balances can end up with very different underwriting results. A borrower with a larger balance but a smaller required payment may qualify more easily than someone with a smaller balance and a heavier monthly commitment.
Student loans are often the most complicated liability. Fannie Mae, Freddie Mac, FHA, VA and USDA all use different rules for deferred loans, income-driven repayment plans and zero-payment situations. FHA and USDA generally require a calculation based on half a per cent of the outstanding balance when no qualifying payment is documented, while Fannie Mae and Freddie Mac can use a documented payment in some cases. VA underwriting can be more favourable when a deferred loan will remain deferred for at least 12 months after closing, although other documentation rules still apply.
Other debts also deserve attention before a mortgage application is filed. Conventional guidelines often include lease payments, even when few instalments remain, and may count short-term instalment loans if the payment is material to the borrower’s finances. Fannie Mae also allows some debts paid by another person to be excluded when the payment history is properly documented, and tax agreements can be acceptable if the monthly instalment is verified. In practice, underwriters want proof, not assumptions, so borrowers should gather statements, court orders and payment records early.
The practical lesson is simple: reducing monthly obligations can improve borrowing power more effectively than paying down a balance with no impact on the required payment. That may mean cutting revolving balances, avoiding new debt, or documenting when another party has been making a liability’s payments. As mortgage lenders across the market repeatedly stress, preparation matters because underwriting is less about total debt on paper than about how much of a borrower’s income is already spoken for each month.
