Debt‑to‑income (DTI) ratio is a key underwriting metric for conventional mortgages. It compares your monthly debt obligations to your gross monthly income and helps lenders gauge whether you can comfortably handle a new mortgage payment.

How lenders calculate DTI

DTI is split into two parts: the front‑end ratio (housing costs only) and the back‑end ratio (all recurring debt, including housing). Both are expressed as a percentage of your gross (pre‑tax) monthly income.

Typical DTI limits for conventional loans

• Front‑end limit: Usually no more than 28% of gross income.
• Back‑end limit: Generally capped at 45% of gross income.
• Higher limits with compensating factors: Lenders may stretch the back‑end ratio to roughly 50% if you have a high credit score, a sizable down payment (often 20% or more), or substantial cash reserves.

Oregon‑specific considerations

Oregon does not have a statewide sales tax, which can reduce overall home‑ownership costs compared with many other states, but property taxes and homeowner’s insurance still factor into your DTI calculation. The state also offers first‑time‑buyer assistance programs through Oregon Housing and Community Services (OHCS) that can provide down‑payment help; participating in such programs may improve your DTI profile by reducing the loan amount you need.

Ways to improve your DTI

• Pay down existing credit‑card balances or other installment loans.
• Increase your gross income through a raise, a new job, or additional legitimate income sources (e.g., rental income).
• Make a larger down payment to lower the loan size.
• Delay major purchases until after closing.
