A DTI denial is often an overlay denial in disguise. Agency programs allow significantly higher DTI ratios than most lenders actually enforce. If "DTI exceeds guidelines" is on your denial letter, the first question is: which guidelines — agency or lender overlay?
Pay down debt: Paying off a $400/month car payment reduces DTI by about 5% on a $80K income. Add income: A co-borrower's income reduces DTI proportionally. Reduce loan amount: Lower purchase price = lower PITI = lower DTI.
Numbers like these tell you what you can afford. They cannot tell you whether a lender will say yes — and that varies more than almost anyone realises. In the complete 2025 federal record, approval rates across the 100 largest FHA lenders ran from 98.2% down to 21.3%. Same program, same year.
And it is not simply who applies where: holding state, loan amount, income, debt-to-income and loan-to-value constant, applicant mix explains only a 2.7× range in expected outcomes.
