What is DTI?

Debt-to-income ratio (DTI) is the percentage of your gross monthly income that goes toward monthly debt obligations. DTI = Total monthly debt payments ÷ Gross monthly income.

DTI limits on jumbo loans

Scenario Maximum DTI
Primary residence, LTV ≤ 80%, loan ≤ $2M Up to 50%
Higher loan amounts or LTV > 80% 45%
LTV > 80% on select programs 38–40%
Second home 40–50% depending on program
Investment property 38–50% depending on program

How specific debts are treated

  • Student loans: Must be included unless fewer than 10 months remain; 1% of balance used if no payment documented
  • Installment loans: Debts with more than 10 months remaining must be counted
  • Revolving debt: Minimum payments on all open accounts must be included; paying off revolving debt to qualify is generally not permitted
  • Child support/alimony: Payments with more than 10 months remaining must be included

How to improve your DTI

  • Pay off installment loans before applying
  • Document all eligible income sources
  • Avoid taking on new debt before applying
  • Consider adding a co-borrower if their income strengthens the application

Most jumbo borrowers qualify in the 38–50% DTI range. If your DTI is above 45%, structuring the application correctly becomes especially important.
