Banks built an entire mortgage product for one profession, and it is not flattery — it is underwriting. Lenders noticed that physician income is unusually predictable and physician defaults are unusually rare, even with six figures of student debt riding along. So they created a loan that waives the standard rules. Understanding exactly what it waives — and what it quietly enables — is worth more than any rate shopping you will ever do.
What a physician mortgage actually is
A physician mortgage (or "doctor loan") is a portfolio loan offered to MDs and DOs — often dentists and veterinarians too — with four signature features:
Little or nothing down. Typically 0 percent down up to $750,000–$1 million depending on the lender, with tiered options (5–10 percent down) at higher price points.
No PMI. A conventional borrower putting less than 20 percent down pays private mortgage insurance — commonly $200–500 a month — which protects the lender against default while the borrower pays for it. The physician loan waives PMI entirely, at any down payment. This is the feature that gives the product most of its honest value.
A signed contract counts as income. Underwriting will accept your employment contract with a future start date as proof of income. A graduating resident can close on a home in June for an August job, before the first attending paycheck exists.
Student debt handled gently. Conventional debt-to-income math can choke on a $250,000 loan balance. Physician-loan underwriting typically counts your actual income-driven payment — or excludes deferred balances entirely.
The trade: rates usually run somewhat above the best conventional pricing, and the approval ceiling is generous. Both matter below.
The real math of 0% down
Zero down is not free money — it is leverage. On a $600,000 home at an illustrative 6.5 percent over 30 years:
- 0 percent down — borrow $600,000: about $3,792/month in principal and interest, roughly $765,000 of lifetime interest.
- 20 percent down — borrow $480,000: about $3,034/month, roughly $612,000 of lifetime interest.
Keeping the $120,000 in your pocket costs about $758 a month and roughly $153,000 more interest over the life of the loan. That is not automatically a bad trade — if those dollars have a better job, the leverage is rational. A new attending carrying a 24 percent credit card, an unclaimed , or an empty emergency fund has three better jobs lined up. A physician with all of that handled, parking the $120,000 in a checking account, is just paying 6.5 percent for the privilege of liquidity she is not using.
The test is your order of operations, not the lender''s brochure: match first, high-interest debt second, emergency fund third — and only then does the down-payment-versus-invest question even become interesting.
The year-one trap
Here is the sequence the product makes frictionless. Sign a contract in March. Close on a house in June with 0 percent down. Start the job in August. Discover by the following spring that the group''s promises were soft, the call schedule is different than advertised, or the city is wrong for your family.
First-job turnover among physicians is famously high — changing jobs within the first few years is common enough that it should be part of your base rate, not an unthinkable surprise. And exiting a house is expensive: agent commissions and closing costs consume roughly 8–10 percent of the home''s value round-trip. On a $600,000 home, that is $50,000 or more of unrecoverable cost — and at 0 percent down, after a year of mostly-interest payments, your equity can be smaller than that. Selling at exactly your purchase price can still mean writing a check to leave.
The rent-first rule: rent for the first 12–24 months of any new job in any new city. It is not a failure of adulthood. It is cheap insurance on the two biggest unknowns in your life — whether the job is what they said, and whether the city is where you want to be. The physician loan will still exist in year two, and you will use it to choose a house rather than absorb one.
Rent versus buy, without the moralizing
"Rent is throwing money away" is the most expensive sentence in first-year attending finance. Owning has unrecoverable costs too: mortgage interest, property taxes, insurance, and maintenance. A useful heuristic — treat it as a starting point, not physics — puts those at roughly 5 percent of the home''s value per year. On a $600,000 home, that is about $2,500 a month that builds nothing, before a dollar of principal.
So the honest comparison is: can you rent an equivalent home for less than the ownership''s unrecoverable costs? Often, early in a career and in many markets, you can — and the down payment you did not bury in the house compounds elsewhere. Buying tends to win when the horizon is honestly five-plus years, the job has survived its first year, and you know which neighborhoods fit your life. Buying tends to lose when the horizon is uncertain — which describes nearly every physician in the first year of a new job.
One more real advantage of buying, from the inflation module''s playbook: a fixed-rate mortgage payment is inflation''s one gift to you. The payment stays constant while prices and (ideally) your income rise — you repay the bank in shrunken dollars. That is a genuine long-horizon benefit. It just does nothing for you in the year you might have to sell.
How much house
The bank will approve more than you should spend — the approval measures their risk appetite, not your plan. A widely used physician-finance guideline: keep the mortgage near 2× gross household income, treated as a ceiling, not a target. A $320,000 attending looking at an $800,000 approval should hear "the bank is comfortable" — not "this is wise." Physicians carry a decade of lost compounding and six figures of training debt; the house that lets you max retirement accounts, clear the loans, and still breathe is the house that makes you wealthy. The bigger one just makes you busy.
The checklist
If a purchase is on your horizon, answer three questions in writing. How many years, honestly, do you expect to be in this city? Is the emergency band funded and the high-interest debt gone? Is the mortgage at or under 2× gross income? Three yeses: get quotes from two or three physician-loan lenders alongside a conventional quote, and let them compete. Any no: rent, run the order of operations, and let the loan be your tool next year — it will still be there.
