A physician mortgage lets a Texas doctor qualify on a signed employment contract instead of paystubs, put little or nothing down without PMI, and handle deferred student debt in a way conventional loans usually can't. It's a portfolio program built around the one borrower who looks risky on paper and almost never is: a new attending with a big income about to start and a pile of student loans behind them.
Doctors get told no a lot. Not because they can't afford the house — because the file looks wrong. No paystubs yet. Six figures of student debt. A job that starts in 60 days in a city they haven't moved to. Standard underwriting chokes on all three. Here's how the math actually works, and where a physician loan earns its keep.
What Is a Physician Mortgage Loan?
A physician mortgage — "doctor loan" — is a portfolio product. The lender keeps it on their own books instead of selling it to Fannie Mae or Freddie Mac, which means they write their own guidelines around how doctors actually earn and owe money.
Three features define it:
- Low to no down payment, no PMI. Most programs allow 0–10% down with zero private mortgage insurance, often well past $1 million.
- Contract-based income. You qualify on a signed offer letter, not 30 days of paystubs you don't have yet.
- Student-debt-friendly DTI. The program uses your real income-driven payment — or excludes deferred student loans entirely.
None of that means the loan is loose. It's still fully underwritten to the same ability-to-repay standard as any other mortgage — the lender still has to verify your income and assets with third-party records under the CFPB's ability-to-repay rule (12 CFR 1026.43). The difference is which documents count and how the debt math runs.
Problem One: The Job Hasn't Started Yet
A resident finishing in June signs an attending contract in March. They want to buy before they move. They have no paystubs from the new job because the job doesn't exist yet.
Conventional financing can actually handle this — within limits. Fannie Mae's Selling Guide allows qualifying on a future employment offer when the start date falls no earlier than 30 days before the note date and no later than 90 days after it. The offer has to be fully executed and non-contingent, and if you don't have a paystub before closing, the lender wants extra reserves — six months of payments, or enough to cover the gap until the paychecks start.
That 90-day box is the catch. Plenty of doctors sign a contract that starts four or five months out. Physician programs are built to stretch past Fannie's window — many will close on a contract that begins well after move-in, with a smaller reserve requirement. For a doctor relocating to Austin, San Antonio, or Houston for a new position, that flexibility is the whole reason the program exists.
Problem Two: The Student Debt
This is where most doctor files die on a conventional loan, and it's the most misunderstood number in the whole process.
If your student loans are deferred or in forbearance, Fannie Mae counts the documented monthly payment, or 1% of the balance if no payment is documented. On $250,000 of medical school debt, that 1% is a $2,500 phantom payment hitting your debt-to-income ratio every month — even if you're actually paying $300 on an income-driven plan, or nothing at all in residency.
There's a path on conventional, too: if you're on an income-driven repayment plan and you can document the actual payment — even a $0 payment — and the plan is still in effect at closing, the lender can qualify you on that real number instead of the 1%. Documentation is everything. No documentation, and you're back to the phantom payment.
Physician programs push this further. Many use your actual IDR payment automatically, and some exclude deferred student debt from the DTI entirely. On a high-debt, early-career file, that single difference is often what moves you from "declined" to "approved" — without changing your income or your house at all.
Conventional vs. Physician Loan — Side-by-Side
| Feature | Conventional | Physician Loan |
|---|---|---|
| Down Payment | 3–20% | 0–10% |
| PMI Below 20% Down | Required | None |
| Income at Closing | Contract OK within 90 days | Contract, often longer runway |
| Deferred Student Debt | 1% of balance or documented payment | Actual IDR payment or excluded |
| Rate | Market rate | Comparable, sometimes slightly higher |
| Best For | 20% down, low student debt, job started | Early career, high student debt, new contract |
Who Actually Qualifies?
Eligibility is about the credential, and it's broader than people think. Most programs cover MD, DO, DDS, DMD, and DPM. Many add residents, fellows, and newly minted attendings — the exact people with no paystubs and the most student debt. Some stretch to nurse practitioners, physician assistants, veterinarians, and pharmacists.
The eligible-degree list varies lender to lender, which is the catch. A program that takes a DDS might not take a DPM. Matching your specific credential to the right lender is half the work — and the part that's easy to get wrong if you only call one bank.
One more thing the income side raises: a lot of physicians aren't W-2 at all. If you're an independent contractor paid on a 1099, or you own your practice, your file looks less like a doctor loan and more like a self-employed loan. I cover that math in detail in the self-employed mortgage guide and the 1099-only mortgage breakdown — both worth reading if your income comes on a 1099 instead of a salary.
When a Physician Loan Is the Wrong Call
I won't push a doctor loan on someone who doesn't need it. If you've got 20% down, your job already started, and your student debt is small or gone, conventional financing is usually cleaner and the rate is hard to beat. The physician program earns its place when you're missing one of those three — the down payment, the start date, or the clean DTI.
And when the price tag runs past conforming limits — common for attendings buying in Austin's core neighborhoods — the comparison isn't always physician-versus-conventional. Sometimes it's physician-versus-jumbo. A well-structured jumbo loan can compete hard on rate at higher loan amounts, and for a borrower with strong reserves it's worth running both side by side. If your file is genuinely outside the agency box on income documentation, the broader non-QM loan options are the third lane to weigh.
What You'll Need
- Fully executed, signed employment contract or offer letter with start date and compensation
- Proof of your degree and license (or residency/fellowship confirmation)
- Documentation of your student loan status — deferment letter or the income-driven payment amount
- Two months of asset statements for down payment and reserves
- Standard credit and ID items
Notice what's not on that list: two years of paystubs from a job you're about to start. That's the point. The contract carries the income, and your lender qualifies the foreseeable, stable earnings the offer represents — consistent with Fannie Mae's general standard that qualifying income must be reasonably expected to continue.
How I Work With Doctors
I run the comparison every time: physician loan, conventional, and — when the number's big enough — jumbo. We pull your real student loan payment, look at your contract start date against the move date, and figure out which program actually fits before you write an offer.
I'm a broker, so I'm not selling one bank's doctor loan. I have access to 40+ wholesale lenders, including the portfolio shops that write physician programs and the non-QM specialists for the 1099 and practice-owner files. You get the option that fits your credential and your debt — not the one product a single bank happens to stock.
If you're a resident, fellow, or attending eyeing a home in Texas, start your pre-approval and I'll reach out personally. Bring the contract and your student loan details — that's where we start.
