Few things derail a physician's mortgage application like student loans. A conventional lender often counts a percentage of your total balance as a monthly payment — and with six figures of medical-school debt, that phantom payment can wreck your debt-to-income (DTI) ratio even when you're paying $0 today. Physician underwriting handles this differently.
When payments can be excluded from DTI
Student loan payments that are in deferment, in forbearance, or reporting as $0 under an Income-Based Repayment (IBR) plan may be excluded from your DTI entirely — provided two conditions are both met:
- You're currently in residency, or in a medical clinical fellowship program, and
- You qualify based on the current income you receive during that residency or fellowship.
Both conditions must be true. The exclusion is designed for physicians who are still in training and earning a training income — exactly the stage where student-loan payments are most likely deferred.
Why this matters for what you can borrow
DTI is one of the biggest levers in how much home you qualify for. Removing a large phantom student-loan payment from the calculation can be the difference between qualifying for the home you actually want and being capped well below it — without changing your income at all.
What to have ready
To document the exclusion cleanly, it helps to gather proof of your current loan status (deferment, forbearance, or $0 IBR) and confirmation of your residency or fellowship and its income. We'll tell you exactly what's needed for your situation and how it flows into the rest of the application.
If student loans have been the reason you assumed you couldn't qualify, this is worth a five-minute conversation. The answer is often more encouraging than physicians expect.
