If you bought a home during residency or your first year as an attending, there’s a decent chance you used a physician mortgage. Those loans are built for people with high earning potential and low current cash, which describes most doctors fresh out of training. What they aren’t built for is staying on your books for 30 years. Many carry slightly higher rates, wider margins, and terms that made perfect sense when you had $40,000 in savings and a signed contract.
Refinancing out of one, or into a better one, is a normal part of the financial arc for physicians. Here’s what actually changes, what to watch, and how to tell whether it’s worth the paperwork.
How physician mortgages differ from standard loans
Physician loan programs, sometimes called doctor loans or MD loans, usually come from banks that hold them in-house rather than selling them to Fannie Mae or Freddie Mac. That gives the lenders room to bend rules that would sink a normal application:
- Up to 100% financing with no down payment
- No private mortgage insurance, even at high loan-to-value
- Higher loan limits than the conforming caps in many markets
- Student loan payments counted more leniently in your debt-to-income ratio
- Underwriting based on a signed employment contract instead of pay stubs
That flexibility has a price. Rates on physician loans often run a quarter to half a percentage point above the best conventional rates, and because these are portfolio products, terms vary wildly from bank to bank. One lender’s physician loan might be an adjustable-rate mortgage with a 10-year fixed period. Another’s might be a 30-year fixed with a small rate premium.
That variance matters when you refinance, because you’re rarely comparing like with like. Two offers with identical headline rates can behave very differently by year eight.
When refinancing a physician mortgage is worth it
The math on any refinance comes down to three things: the rate drop, the closing costs, and how long you plan to stay. Doctors add a fourth. Your income and debt profile may have changed enough to unlock loan types that simply weren’t available to you before.
Your rate dropped or your credit improved
Say you closed on a $650,000 physician loan at 6.5%. Three years later your score is up 60 points, you’ve built 12% equity, and rates for someone with your profile are 5.75%. On a fresh 30-year loan that’s roughly $315 less per month, or about $3,780 a year. If closing costs land near $5,000, your break-even is around 16 months.
You’ve moved from resident income to attending income
A resident earning $62,000 who bought a $400,000 house is a different borrower from the attending earning $340,000 three years later. Lenders that wouldn’t touch you before now compete for your business. That can mean access to conventional financing with sharper pricing, or a straightforward rate-and-term refinance that strips out the physician-loan premium entirely.
Your student loan situation has shifted
Student loan treatment is arguably the biggest lever in this whole process. Many physician loan programs let you use your actual income-driven repayment amount, which could be $300 a month against a $250,000 balance, rather than applying a percentage of the balance itself.
Standard agency guidelines have historically used 1% of the outstanding balance for deferred or income-driven loans. On $250,000, that’s $2,500 a month of phantom debt dragging your debt-to-income ratio down. If your loans are now in a documented repayment plan, or you’ve moved them to a private lender, a conventional underwriter may count a far smaller number. That one change can swing your qualification enough to land a materially better loan.
Worth pausing on, though: refinancing federal student loans into a private loan just to help a mortgage application is a real trade-off. You give up income-driven repayment, Public Service Loan Forgiveness eligibility, and federal forbearance options. Take that question to a financial planner, not only to a loan officer.
You want to pull cash out for a specific purpose
A cash-out refinance can fund a practice buy-in, a down payment on a rental property, or a renovation. Equipment and office space usually need separate commercial financing, but buy-ins and real estate are fair game. Be honest with yourself about whether you’re trading 9% credit card debt for mortgage debt stretched over 30 years. Rolling $30,000 of debt into your mortgage lowers the monthly payment while raising total interest paid. If the goal is breathing room during a tight transition, that can be reasonable. If the goal is making debt vanish, it doesn’t.
When refinancing doesn’t make sense
- You expect to move within two years, so you’ll never recoup closing costs
- Your break-even timeline runs longer than your realistic stay in the house
- You’d reset a 30-year term at year 22 to save $60 a month
- You’d swap a fixed rate for an ARM purely to grab a lower teaser rate
- You’d roll costs into the loan and push your balance back above 80% LTV
What the refinance actually costs
On a $650,000 refinance, typical closing costs break down roughly like this:
- Appraisal: $500 to $800
- Title search, lender’s title insurance, and settlement fees: $1,500 to $3,000
- Origination or underwriting fee: $0 to $1,500, since some physician programs waive these
- Recording and government fees: $100 to $400
- Prepaid interest and escrow funding: varies, sometimes several thousand
All in, expect 1% to 2% of the loan amount. Ask every lender for a Loan Estimate and compare the “services you can shop for” section line by line. Physician programs that advertise no lender fees usually bake the cost into a slightly higher rate, which is fine if you’re staying put and not so fine if you’re not.
Rate locks and the timing trap
Once you’re approved you’ll lock your rate, and that lock has an expiration date. Miss it because an appraisal ran long or your employer took three weeks to return a verification of employment, and you may pay for an extension. It also helps to understand what a lender can and can’t do between lock and closing. Whether mortgage rates can change before closing depends on the terms of your lock agreement, not on how the bond market feels that week.
If rates are falling while you’re under contract, ask about a float-down provision. Some lenders include one free, others charge a fee. Get the answer in writing before you lock, not after.
Questions worth asking every lender
- Does this physician loan program carry a prepayment penalty? Rare, but not unheard of.
- How exactly do you count income-driven student loan payments in my DTI?
- Is there a recast option if I make a large principal payment later?
- If this is an ARM, what’s the adjustment schedule and what are the lifetime caps?
- Will you service the loan in-house, or sell it within 90 days?
Vague answers tell you plenty about what servicing will feel like in year four. So does a loan officer who can’t explain the break-even math on your own numbers.
Run that break-even first. If it lands under two years, you’re staying put, and your student loan payments are now documented at their real amount, the refinance is usually worth an afternoon of paperwork. Doctors spend years optimizing other people’s health. Spending one Saturday comparing three Loan Estimates side by side is a pretty good use of a day off.
