A physician loan wins on qualifying; a conventional loan often wins on long-term cost. That's the whole comparison in one sentence, and most of the articles you'll find make it more complicated than it is. The useful question isn't which product is better in the abstract — it's whether qualification is currently your constraint. If it is, the physician loan exists to solve exactly that. If it isn't, you may be paying for flexibility you don't need.
Key takeaways
- The real difference is underwriting, not the loan itself. Both are 30-year mortgages on the same house. What changes is how a lender is permitted to evaluate you.
- Student loan treatment decides most files. How your balance converts to a monthly payment for debt-to-income purposes varies enormously by repayment plan and by program.
- Conventional pricing is generally more predictable because the loan is sold to Fannie Mae or Freddie Mac. Portfolio physician loans are priced by the individual bank.
- You are not locked in. A physician loan can usually be refinanced into conventional financing later once income history and equity are established.
- Compare Loan Estimates, not marketing pages. The only honest cost comparison is two Loan Estimates for the same house on the same day.

What Actually Differs Between the Two
The difference is who ends up owning the loan. A conventional conforming mortgage is written to be sold to Fannie Mae or Freddie Mac, which means it must follow their published underwriting rules exactly. A physician loan is a portfolio loan — the bank keeps it on its own balance sheet and writes its own rules.
Everything people describe as a "benefit" of a physician loan traces back to that one structural fact. The bank can be flexible because the bank is holding the risk.
Portfolio loan — a mortgage a lender originates and retains rather than selling into the secondary market. Because the lender carries the risk itself, it sets its own eligibility criteria instead of following agency guidelines.
| Underwriting factor | Physician loan | Conventional conforming |
|---|---|---|
| Who owns the loan | The originating bank, on its own books | Sold to Fannie Mae or Freddie Mac |
| Income proof | A signed employment contract may be accepted before you start | Generally requires pay stubs and established history |
| Student loan calculation | Program-specific; may use actual payment or exclude deferred debt | Fixed formula published in the agency selling guides |
| Mortgage insurance | Generally structured without monthly PMI | PMI applies until equity reaches the agency threshold |
| Who qualifies | Defined degree designations only, typically MD, DO, DDS, DMD | Anyone meeting agency credit and income standards |
| Property types | Often restricted, frequently primary residence only | Primary, second home, and investment property all eligible |
| Pricing | Set by the individual bank; varies widely between lenders | Anchored to the agency market; more uniform across lenders |
General comparison for educational purposes. Specific terms, ratios, and eligibility vary by lender, program, property type, and borrower profile, and are subject to change. All loans subject to credit approval.
Notice what is not on that list: the interest rate. Rate comparisons between the two products depend on the day, the lender, the loan size, and your credit profile. Anyone who tells you one is categorically cheaper is guessing. The Loan Estimate is the standardized form that exists precisely so you can compare two offers honestly — get one for each and compare them side by side.
How Your Student Loans Get Counted
This is the variable that decides more physician files than credit score, income, or down payment combined. Your student loan balance doesn't enter the underwriting math directly — a monthly payment derived from that balance does, and it lands in your debt-to-income ratio.
The derivation is where the two products separate. Agency guidelines prescribe how a lender must calculate that payment, including for loans that aren't currently requiring one. A portfolio physician program can use a different method.
| Your repayment status | Typical conventional treatment | Typical physician-program treatment |
|---|---|---|
| Income-driven repayment (IDR/IBR/PAYE/SAVE) | Agency rules permit the actual documented payment in defined circumstances | Actual documented payment commonly used |
| Deferment or forbearance | A calculated payment is generally still assigned | May be excluded entirely if deferred for a defined period |
| Standard amortized repayment | Actual payment used | Actual payment used |
| In-school or grace period | A calculated payment is generally assigned | Treatment varies significantly by program |
Treatment varies by lender and program and is subject to change. Confirm current agency requirements in the Fannie Mae Selling Guide and your current repayment status at studentaid.gov.
The practical version: a resident carrying a large balance on an income-driven plan can look like two completely different borrowers depending on which product is evaluating the file. That gap is the entire reason physician programs exist. It is also why the first document I ask for is your student loan documentation, not your pay stub.
When the Physician Loan Is the Right Call
A physician loan is generally the better answer when qualification, not cost, is the binding constraint. Four situations where that's usually true:
- You have a signed contract but no pay history. You're finishing training, you have a start date, and a conventional lender wants stubs you cannot produce yet.
- Your student loan payment breaks your debt-to-income ratio. The conventional calculation assigns a payment large enough to disqualify you; the portfolio calculation does not.
- Your savings are earmarked elsewhere. Relocation, licensing, board fees, and practice buy-in all compete for the same cash. Preserving liquidity has real value even when it costs something.
- Your income structure is unusual. 1099 contract income without two years of history is a common sticking point that some physician programs are built to handle.
Eligibility requirements apply and not all applicants will qualify. Programs are typically limited to specific degree designations and to primary residences.
When the Conventional Loan Is the Right Call
A conventional loan is frequently the better answer once you can clear its qualifying bar, and I say that as someone who originates both. If you have documented income, established credit, and enough saved to reach the equity threshold where mortgage insurance no longer applies, the specialty product is solving a problem you no longer have.
Conventional financing also carries structural advantages that rarely make it into comparison articles:
- Broader property eligibility. Second homes and investment properties are generally available; most physician programs are primary-residence only.
- More consistent pricing across lenders, because the loan is priced against the same secondary market everywhere.
- Portability of the comparison. Conforming loans are easier to shop, which gives you real negotiating leverage.
If your purchase price puts the loan above the conforming ceiling, the comparison changes shape entirely and becomes a question of jumbo structure instead. The 2026 baseline conforming loan limit is $832,750 for a one-unit property, with a high-cost ceiling of $1,249,125. Every Arizona county uses the baseline figure.
You Are Not Locked In for 30 Years
The decision feels permanent and generally isn't. A physician loan can usually be refinanced into conventional financing later, once you have documented attending income and enough equity to clear the agency threshold — which for most new attendings is a matter of a few years, not decades.
That reframes the choice usefully. You are not picking the loan you'll hold for thirty years. You are picking the loan that gets you into the house you want now, with the option to restructure once your financial picture matures. Three things worth confirming before you assume that exit is available:
- Whether the loan carries a prepayment penalty — many physician programs do not, but confirm rather than assume
- What your break-even point looks like on a future refinance, factoring in closing costs
- Whether the rate structure is fixed or adjustable, since that changes how much time you actually have
Every borrower's situation is different, and this page is educational rather than personal advice. What's right depends on your contract, your loan balances, your timeline, and the house.
Frequently Asked Questions
Is a physician loan a conventional loan?
No. A conventional loan is written to agency guidelines and sold to Fannie Mae or Freddie Mac. A physician loan is a portfolio loan the originating bank keeps on its own books, which is what allows it to apply different underwriting rules to student debt, employment history, and mortgage insurance. Both are conventional in the broad sense of being non-government loans, but they are different products with different rules.
Do physician loans have higher interest rates than conventional loans?
Not categorically. Pricing on a portfolio physician loan is set by the individual bank, so it varies more between lenders than conforming pricing does. Depending on the day, the lender, and your profile, it may be higher, lower, or comparable. The only reliable way to know is to obtain a Loan Estimate for each option for the same property and compare them directly.
Can I buy an investment property with a physician loan?
Usually not. Most physician programs are restricted to a primary residence, and some also limit eligible property types — excluding certain condos or multi-unit properties. Conventional financing is generally the route for second homes and investment properties. Program restrictions vary by lender and are subject to change.
Does a physician loan hurt my offer in a competitive market?
It shouldn't, if your pre-approval is done properly. What sellers and listing agents react to is the strength and specificity of the pre-approval letter, not the product name on it. A fully underwritten pre-approval carries more weight than a preliminary one regardless of loan type. If an agent pushes back on the product, that's usually unfamiliarity rather than a real risk.
Which professions qualify for a physician loan?
Eligibility is defined by degree designation and varies by lender. Most bank programs cover MD, DO, DDS, and DMD, and include residents and fellows still in training. Some lenders extend eligibility to a broader set of advanced medical professions; many do not. If you hold a designation outside the common list, confirm eligibility before you shop for a home rather than after.
Can I refinance a physician loan into a conventional loan later?
In most cases yes, once you have documented income history and sufficient equity to meet agency requirements. Confirm your specific loan has no prepayment penalty, and weigh the closing costs of a future refinance against the savings before treating it as a certainty. Refinancing is subject to credit approval and prevailing program guidelines at the time you apply.
