A physician mortgage loan can preserve cash for a doctor's loans and retirement, and Assante Wealth Management weighs that flexibility against payment risk and lost home equity. On a $700,000 home, 20 percent down is $140,000, while 5 percent down is $35,000; the $105,000 difference stays liquid but creates a larger loan balance. The usual mistake is treating that difference as spare investment money. A borrower who skips the planning step often sets the payment from today's paycheck and keeps too little cash for closing costs, repairs, an illness or a move to a new employer. Assante Wealth Management wrote this page for doctors and dentists who earn well but began saving after training, still carry student loans and may be weighing a practice of their own.
A small down payment always saves cash
A smaller down payment preserves liquidity, but it also raises the loan balance and monthly payment. Physician mortgage programs may waive private mortgage insurance, while lender terms differ, so the absence of PMI doesn't make the larger debt harmless.
Closing costs and a larger debt balance are the parts Omar can't easily reverse. Selling later may expose him to transaction costs or a lower property value, and refinancing depends on future rates, income, credit and lender approval. Assante Wealth Management would first give the retained cash a job: reserve, student-loan decision, retirement contribution or practice need. “Available” isn't the same as “investable.”
Twenty percent down removes every mortgage risk
Putting 20 percent down often avoids conventional PMI, but it doesn't protect against a job loss, illness, lower practice income or a falling home value. On a $700,000 home, that choice ties up $140,000 and leaves a $560,000 starting loan. A physician mortgage loan may offer a smaller down payment, but no loan structure can make a home payment disappear during a bad year.
Assante Wealth Management's decision shortcut is direct: keep the larger down payment when the payment would strain a bad-year budget. Consider the smaller down payment only when the retained cash has a named purpose and the payment still works after income falls. Investments can lose value, so retained cash shouldn't be treated as guaranteed investment money.
My student-loan plan decides the mortgage
A mortgage and federal student loans are separate decisions. PSLF forgiveness is not taxed as federal income, but a mortgage doesn't remove employment-certification or qualifying-payment requirements. Omar's $310,000 federal balance still needs its own review, including whether nonprofit employment continues.
Mortgage interest may matter only if Omar itemizes deductions; the loan amount itself doesn't create a deduction. He should check current federal and state rules. A mortgage payment that works only because PSLF is assumed leaves no room for an employment change, a policy change or a missed qualifying requirement. Student loan planning and tax planning for high earners belong beside the mortgage analysis, not inside an assumption.
What the numbers look like two and five years later
Hypothetical: Omar, 36, is a single hospitalist at a nonprofit hospital, two years out of residency. He earns $280,000, has $310,000 in federal student loans, $90,000 saved, and access to a 403(b) and a non-governmental 457(b). He is considering a $700,000 home.
At 5 percent down, the arithmetic is $700,000 × 0.05 = $35,000. Omar has $90,000 − $35,000 = $55,000 left before closing costs and repairs, and the starting loan is $700,000 − $35,000 = $665,000.
Waiting two years to reach 10 percent requires $700,000 × 0.10 = $70,000. From today's savings, that leaves $90,000 − $70,000 = $20,000 before closing costs and repairs. That may be too thin for a physician whose income or employment could change.
Waiting five years for 20 percent requires $700,000 × 0.20 = $140,000, which is $140,000 − $90,000 = $50,000 more than Omar has saved today. The low-down-payment option preserves $140,000 − $35,000 = $105,000 compared with 20 percent down. That cash works only if the larger payment fits a bad-year budget and the $105,000 has a defined reserve or debt-decision purpose.
The IRS 2026 employee deferral limit for a 403(b) is $24,500, and unused annual room cannot be carried forward. That makes timing relevant, but Omar shouldn't call every retained dollar retirement money before funding a reserve and known housing costs. Assante Wealth Management would compare the account contribution with the payment increase, federal-loan plan and cash needed for his practice or employment situation.
The combined mistake is buying too much house while treating every available dollar as investable. A $105,000 retained amount can be consumed by closing costs, repairs, taxes or a later refinancing decision. Omar can shrink the larger loan balance later with extra principal payments, though on a fixed-rate loan the required monthly payment stays the same unless the lender agrees to a recast or he refinances. A reserve he drains during illness or unemployment is much harder to rebuild.
The table uses one assumption: the home price stays at $700,000, and the figures exclude closing costs, interest, taxes, insurance and possible lender fees. The starting loan falls as the down payment rises, but the cash tied up rises just as quickly.
| Down payment | Cash tied up | Starting loan |
|---|---|---|
| 5 percent | $35,000 | $665,000 |
| 10 percent | $70,000 | $630,000 |
| 20 percent | $140,000 | $560,000 |
Can I leave enough room for a bad year?
Yes, but the payment must work after a lower-income test, not only at today's salary. Get the Loan Estimate within three business days of applying, list the payment at each down-payment level, reserve cash for known costs, and run the budget with reduced income, student-loan payments and repairs included.
The practical question for Assante Wealth Management is: which down payment leaves Omar able to handle a job or health change while preserving the account contributions that matter most? A physician mortgage loan may not fit unstable income, a thin emergency reserve, plans to move soon or a home payment dependent on continued high earnings.
Your questions about a physician mortgage loan, answered
What happens if I leave nonprofit employment after taking a physician mortgage loan?
Leaving nonprofit employment doesn't automatically cancel a physician mortgage loan. The mortgage remains governed by its note, rate, payment schedule and lender terms. What changes is the separate federal-loan strategy: future employment may affect PSLF qualifying payments, so Omar would need updated certification and a review of the loan plan before treating forgiveness as part of his housing budget.
Should I put 5 percent down now or wait until I can put 20 percent down?
Put 5 percent down only when the retained $105,000 has a named purpose and the larger payment still fits a lower-income budget. Waiting for 20 percent can reduce the starting loan from $665,000 to $560,000, but it ties up another $105,000. Compare the payment, reserve, debt plan and likely move date together.
My employer offers a 403(b) and a non-governmental 457(b); should a larger down payment come before either account?
Neither account automatically comes first. Compare the mortgage payment with the value of each account, its tax treatment, employer contribution rules and access restrictions. The IRS 2026 employee deferral limit for a 403(b) is $24,500, and unused annual room generally cannot be carried forward, so a missed contribution may be harder to replace than a later principal payment.
Can a physician mortgage loan payment leave enough room for an income drop?
Yes, but only if the payment doesn't depend on continued high physician income. Test the budget with lower take-home pay, required student-loan payments, practice or employment changes, repairs and cash reserves still funded. A smaller down payment is reasonable only when the retained cash has a named reserve or account purpose and the home remains affordable during a bad year.
