Physician Mortgage Loans: The Doctor Loan Guide for 2026

You just signed your first attending contract. You have $280K in student loans, you haven't seen a paycheck yet, and you want to buy a house. A conventional lender looks at that picture and says no. That's why physician mortgage loans exist.

They're a real, widely available product — and they solve a specific problem. But they're not always the right answer. Here's what they actually do, what they cost, and the decision framework that matters for physicians specifically.

What is a physician mortgage loan?

A physician mortgage (also called a "doctor loan" or "physician home loan") is a mortgage product offered by specialty lenders and major banks, designed specifically for medical professionals. The underwriting relaxes three conventional rules that otherwise disqualify most newly-minted attendings:

1. No PMI, even with less than 20% down. Conventional loans require private mortgage insurance when you put down less than 20%. On a $600,000 home with 5% down, PMI runs $230–$460/month.¹ Physician loans waive this entirely.
2. Student loans counted differently in your DTI. On a conventional loan, your full student loan minimum payment counts against your debt-to-income ratio. On most physician mortgages, income-driven repayment (IDR) payments are used instead of a calculated percentage of your total balance — which dramatically lowers your DTI on paper and allows you to qualify for far more house.
3. Employment contract accepted as income documentation. Conventional underwriting requires 2 years of W-2 history. Physician programs accept a signed offer letter or employment contract, meaning you can close before your first paycheck.

The real math: is the rate premium worth it?

The trade-off is straightforward. You're paying a slightly higher interest rate in exchange for no PMI and lower-barrier entry. Whether that's a good deal depends on your specific loan size and down payment.

Example: $600,000 home, 5% down ($30,000).

• Loan amount: $570,000
• Conventional with PMI (at 0.5% annually): ~$238/month PMI for several years until you hit 20% equity
• Physician mortgage at +0.25% rate: ~$95/month higher interest payment

In this scenario, the physician loan wins — you save roughly $143/month and lose the PMI cancellation requirement. At larger loan amounts and lower down payments, the gap widens further in favor of the physician loan.

The calculation flips if you're comparing to a conventional loan with a full 20% down payment. Then there's no PMI, and the only variable is the rate premium. On a $570K loan at 0.25% rate premium, that's about $1,400/year in extra interest. That's the true cost of the physician loan vs. waiting and saving a 20% down payment.

The down payment opportunity cost problem

Here's what most physician mortgage discussions miss: the bigger question isn't whether to use a physician loan. It's whether to put any money down at all — and what else you'd do with that cash.

Say you have $80,000 available. Your options:

• Use it as a 13% down payment on a $600K home via conventional loan, eliminating PMI once you hit 20%. Gets you out of PMI faster, slightly lower rate.
• Use a physician loan with 0% down and keep the $80K. You could use it for maxing retirement accounts ($24,500 solo 401(k) deferral limit in 2026,³ plus employer match if you have one), funding a backdoor Roth, or building an emergency fund that isn't tied up in home equity.

For a resident or fellow finishing training with $280K in student loans and no emergency reserve, putting $80K into a down payment can leave you dangerously illiquid in the early attending years when your expenses suddenly multiply. Many physician-focused advisors argue that preserving liquidity during this transition is worth the rate premium on a physician mortgage.

The PSLF interaction

If you're pursuing Public Service Loan Forgiveness, this changes the calculus meaningfully. On PSLF, your monthly loan payment is calculated on an income-driven plan (PAYE or IBR). A physician mortgage uses that same IDR payment in your DTI — which may be low or even $0 during residency if your income was modest.

On PSLF, your goal is low monthly payments to maximize forgiveness. Large cash reserves are more useful than large down payments because they don't affect your required payment. Using a physician loan with 0% down and preserving cash makes more sense here than it does for a physician who plans to refinance and aggressively pay off loans.

Buy vs. rent: the physician-specific decision

For physicians, the buy vs. rent question is complicated by one thing most financial calculators don't model well: the relocation risk.

• If you're finishing residency and you're not sure you'll stay at your first attending job, buying is a risk. Selling a home within 2–3 years of purchase often loses money once you account for transaction costs (6% realtor fees, transfer taxes, closing costs on both ends).
• Fellowship-to-attending transitions, job dissatisfaction in the first 2 years (common), and practice-sale scenarios all create relocation pressure at exactly the time when you've had the house for too short a period to benefit from appreciation.
• If you're joining a practice with a partnership track you're committed to, or a hospital system in a city you intend to stay in, the buy calculation is very different.

A general rule used by physician-specific planners: if there's a meaningful chance you'll move within 3 years, renting is probably the better financial outcome despite the psychological appeal of building equity.

When a physician mortgage makes sense

• You're starting your first attending role in a city/practice you expect to stay in for 5+ years
• You have limited liquid savings and would be stretched by a 20% down payment
• Your student loans are on IDR or PSLF — preserving cash matters more than reducing debt
• You've already max-funded your retirement accounts and still have no down payment saved

When to think twice

• You're in a subspecialty fellowship with uncertain job placement geography
• You have enough cash for 20% down without depleting emergency reserves — a conventional loan at lower rate may be better
• You're refinancing student loans aggressively — in that scenario, cash toward down payment may compete poorly with loan payoff returns
• The home you're eyeing requires more than a 30% of gross income monthly payment — a physician loan can let you qualify for more house than is wise

Questions a financial advisor helps answer

A physician mortgage decision doesn't exist in isolation. It interacts with your student loan strategy, retirement contribution timeline, emergency fund, and whether you're building toward a practice purchase. A fee-only advisor who works with physicians can model your full picture:

• Should you use the physician mortgage with 0% down, or put 5–10% down and avoid a bigger loan?
• If you preserve cash by not making a down payment, what do you actually do with that cash?
• How does your PSLF vs. refinance decision affect the home-buying math?
• At what income level does buying vs. renting tip in each direction in your market?
