Physician Mortgage Calculator

A physician mortgage (also called a doctor or professional loan) lets eligible healthcare professionals buy a home with little or no down payment and no private mortgage insurance (PMI), even with large student loans. That's powerful — and it makes it easy to buy more house than you need. This calculator shows the monthly payment, how lenders will see your debt-to-income ratio, and how much PMI you'd avoid.

What this calculator does

Enter the home price, down payment, interest rate, loan term, property tax rate, home insurance, HOA dues, your gross income, other monthly debts, and the student loan payment a lender will count. It shows:

• your monthly payment, including principal, interest, property tax, insurance and HOA,
• the loan amount,
• your back-end debt-to-income ratio (DTI),
• PMI you avoid compared with a conventional loan, and
• the maximum price that keeps your DTI at 43%.

The formula in plain English

Principal and interest uses the standard mortgage formula for your rate and term.

Monthly payment = principal and interest + (price × property tax rate ÷ 12) + (insurance ÷ 12) + HOA.

Back-end DTI = (monthly payment + other debts + counted student loan payment) ÷ gross monthly income. Many lenders cap this near 43%.

PMI avoided. With less than 20% down, a conventional loan usually requires PMI. The calculator estimates it at 0.6% of the loan per year.

Maximum price works backward from a 43% DTI to the price whose payment would fit.

A worked example

Dr. Chen is finishing residency with a $300,000 offer and is looking at a $650,000 home with 5% down. The physician loan rate is 6.65% for 30 years. Property tax is about 1.1%, insurance $2,400 a year, and she has a $500 car payment. Her lender ignores her deferred student loans.

• Loan amount: $617,500.
• Monthly payment: about $4,760.
• DTI: about 21% — comfortably under 43%.
• PMI avoided: about $309 a month versus a conventional loan.
• At 43% DTI, the lender might approve up to about $1.4 million.

She could borrow much more, but $4,760 a month is already around a quarter of her expected take-home pay. That's a comfortable ceiling.

Why it matters at each career stage

If you're: Resident / fellow

Buying during training can work if you'll stay at least five to seven years, but many residents move for fellowship or a first job. Run the rent vs buy calculator before committing.

If you're: Employed

The first years after training are when lifestyle creep is most expensive. A home well below your approval amount leaves room to pay down loans, save for retirement and build an emergency fund.

Approval amount vs. comfortable amount

Lenders approve based on gross income and a 43% DTI. Your budget runs on take-home pay, which is often 60% to 70% of gross for high earners once taxes, retirement savings and insurance come out. A payment that's 25% of gross income can easily be 40% of take-home pay. Many planners suggest keeping total housing costs to roughly two times your gross annual income in home price, or about 25% to 30% of take-home pay in monthly payment.

Before you apply

Get several quotes, including at least one conventional loan with PMI. Sometimes a lower rate with PMI costs less over time.

Ask about rate type. Some physician loans are adjustable-rate. Know when and how the rate could change.

Budget for the extras: maintenance (often 1% of the home's value a year), furniture, and higher utilities.

Keep an emergency fund. A zero-down purchase with no cash cushion is risky. See the emergency fund calculator.
