What a physician mortgage actually is

A physician mortgage loan — sometimes called a "doctor loan" — is a portfolio mortgage product written for a specific professional segment. It is not a single nationwide product; each participating bank or credit union sets its own underwriting criteria, eligible specialties, and terms. The reason these products exist is straightforward: physicians have a credentialed earnings curve that almost guarantees high future income, but during residency and early attending years they often carry high student-loan balances and limited cash reserves. A standard conventional loan at 0–10% down would either require expensive private mortgage insurance or be denied. The physician mortgage exists because the lender has decided that a credentialed MD or DO is a different credit risk than the income-and-down-payment math alone implies.

The four structural advantages over a conventional loan

Across the dozen or so banks that offer a recognizable physician-loan product, four structural advantages tend to recur. The exact terms differ by lender — confirm each in writing during pre-approval — but the pattern is consistent.

1. Low or zero down payment. Many physician mortgages allow 0–5% down on loan amounts that would normally require 20%. The maximum loan amount with a low down payment varies by lender and tends to step down for jumbo balances.
2. No private mortgage insurance (PMI). A conventional borrower below 20% down ordinarily pays PMI on top of the principal-and-interest payment. Physician mortgages typically waive PMI entirely. Over the life of a loan this can be a meaningful savings — the exact dollar value depends on the loan size, the PMI rate, and how long the borrower stays below 20% equity.
3. Friendly student-loan handling in DTI. Conventional underwriting typically uses a fully-amortized student-loan payment in your debt-to-income calculation, which is harsh for a resident on income-driven repayment. Most physician mortgage lenders use the actual documented IDR payment, or sometimes exclude deferred loans entirely. This is often the difference between approval and denial.
4. Employment-contract income recognition. Many physician mortgage lenders will issue a pre-approval based on a signed attending employment contract before the borrower has a single pay stub from the new job. This makes the product unusually well-suited to the resident-to-attending transition where the borrower has a job offer in hand but no work history at the new salary.

The trade-offs nobody puts in the brochure

Physician mortgage products are not free. The structural advantages above come with consistent trade-offs that the marketing material rarely highlights:

• Slightly higher rate. Most physician mortgage products quote a rate higher than the same lender's best conventional 30-year fixed for an equivalent borrower at 20% down. The spread varies week to week — sometimes 0.125%, sometimes 0.5% or more. The PMI savings can outweigh the higher rate, but the math depends on how long you stay in the home and how quickly you build equity.
• Adjustable-rate options dominate the headline rates. Many physician mortgage marketing pages lead with a 5/1 or 7/1 ARM rate that looks unusually low. A 30-year fixed is usually available, but at a higher rate. ARMs are not inherently bad, but be sure you know which product you're being quoted.
• Limited resale market for the loan. Physician mortgages are typically held in the lender's portfolio rather than sold to Fannie/Freddie. That has no effect on you as a borrower except that some product features (like assumability) are not available.
• The loan amount can encourage buying too much house. If a lender will write you a 0%-down jumbo at the resident-to-attending transition, the temptation is to buy a house at the upper end of what's approved. Physician-finance writers are nearly unanimous that this is the single biggest mistake physician homebuyers make. The lender's approval ceiling is not your "right" budget — your fixed-expense budget is.

Physician mortgage vs. conventional 20%-down: when does each win?

The honest answer is that a conventional 20%-down loan is usually the cheaper product over the life of the loan if you have the cash reserves to make it work without depleting your emergency fund. The borrower who comes out ahead on the physician mortgage typically has at least one of these characteristics:

• Limited cash reserves. Putting 20% down on a $700,000 house in a high-cost-of-living metro requires $140,000 in cash plus closing costs and reserves. Many residents and early attendings simply do not have it. The physician mortgage lets you buy without depleting your runway, which has its own value beyond pure interest math.
• Strong investment alternative. If the difference between 0% down and 20% down is $140,000, and that $140,000 has a credible 7-10% expected return in equity index funds while the mortgage rate is 6.5-7%, the opportunity cost of putting it into the house is real. This is a tax-aware calculation — talk to a fee-only fiduciary.
• Resident-to-attending transition. The lender's willingness to underwrite on the contract is often the only path to closing during the gap year between jobs. A conventional lender may not approve at all.
• Stable metro intent. The math improves the longer you hold the house. A physician buying in their long-term metro and likely to hold 7+ years has a much better case than one buying for a 3-year fellowship.

Conversely, if you are several years into attending practice with a healthy 6-month emergency fund and 20% saved on top, the conventional loan is usually the cleaner product.

Resident, fellow, attending: when (and whether) to buy

A separate question from "which loan?" is "should I buy at all?" Most physician-finance writers come down hard on residents in particular: residency length is short, transaction costs are real (typically 8-10% of sale price round-trip), and the housing market does not reliably generate enough short-term appreciation to clear those costs. There are exceptions — a resident staying in the same metro for fellowship and attending, a dual-physician household where one income easily covers carry, a buyer in a market where rent itself is unusually high — but the default for a single resident is rent.

For attendings, the calculus shifts. Once you've signed a long-term position and intend to stay 5-10 years, the physician mortgage becomes one of the most defensible uses of the product. Even then, the rule of thumb in the physician-finance community is to keep the housing payment (principal + interest + taxes + insurance + HOA) under roughly 2× monthly gross income for the loan, often phrased as "house price under 2× annual income" — a guideline cited in widely read physician-finance writing. The lender will approve you for more. Don't take it.

How to compare physician mortgage lenders

There is no single best physician mortgage lender. The product is competitive enough that the right lender for one borrower is the wrong lender for another. The repeatable framework is:

1. Get three lender quotes in the same week. Lender pricing moves with rates. Quotes from different weeks aren't comparable. Ask each lender for a Loan Estimate at the same loan amount, term, and down payment.
2. Compare APR, not just headline rate. The headline rate is a marketing number. APR includes lender fees and is closer to the all-in cost. Loan Estimates make this comparison easy because the format is standardized by federal rule.
3. Read the rate-lock terms. A 30- or 45-day lock is standard. Longer locks usually cost more. Confirm what happens if your closing slips.
4. Confirm DTI treatment of student loans in writing. If the entire reason you're using a physician mortgage is favorable IDR-payment treatment, get the lender's specific rule documented before you commit.
5. Confirm the down-payment-vs-loan-size schedule. Most products allow 0% down only up to a specific cap (often $1M or so), with stepped down-payment requirements above that. Confirm you fit the schedule for the price point you're targeting.
6. Confirm whether the rate is fixed or adjustable. Always.

Banks commonly cited in the physician-finance community for active doctor-loan programs have included BMO, Bank of America, Citizens, Fifth Third, First Horizon, Huntington, KeyBank, Truist, US Bank, and several regional credit unions. Availability changes by state and over time; confirm with current sources before choosing.

A simple math check before you sign

Before signing a Loan Estimate on any mortgage, run a sanity check that takes ten minutes:

• Total monthly housing cost (PITI + HOA) ≤ 2× monthly take-home? If no, walk away from this house.
• Cash reserves after closing ≥ 3 months of full living expenses? If no, raise the down payment, lower the price, or wait.
• Time in metro ≥ 5 years (ideally 7)? If no, rent.
• You have an active fee-only fiduciary advisor who's seen the numbers? Ideal.
• Student-loan strategy decided? Refinancing into a private loan can cost you forgiveness eligibility, so order matters; see our side-income guide and the physician guide for context.
