Should Residents Buy a House in 2026? Student Loans, Mortgages, and the Real Math

A PGY-2 general surgery resident in a 5-year program asks a reasonable question: should I buy a house now and build equity, or keep renting and wait until attending life? With $320,000 in student loans and a $67,000 salary, the answer matters more than most residents realize — and it's more nuanced than "renting is throwing money away."

Here's the full analysis, including how student loans specifically affect your mortgage options.

How Student Loans Affect Your Mortgage Eligibility

The central issue for residents isn't income — lenders know physician incomes rise dramatically. The issue is debt-to-income ratio (DTI).

Lenders calculate DTI as your monthly debt obligations divided by gross monthly income. Most conventional loans require DTI under 43–45%.

Take a resident with $320,000 in loans at a standard 10-year payment of $3,700/month and a $67,000 salary:

• Monthly gross income: $5,583
• Monthly debt (standard repayment): $3,700
• DTI before housing: 66% → loan denied

Switch to IBR at $262/month:

• DTI before housing: 4.7% — plenty of room

Here's the catch: Which payment does the lender actually use?

Conventional and FHA Loans: Use 1% of Balance

Fannie Mae and FHA guidelines require lenders to use either your actual payment or 1% of your outstanding loan balance, whichever is higher, if you're on an income-driven plan.

1% of $320,000 = $3,200/month imputed payment

This makes conventional mortgage qualification nearly impossible for residents on IBR with large balances. You'd get rejected despite having room in your actual budget.

Physician Loan Programs: The Solution

Physician mortgage loans (also called doctor loans) are portfolio products offered by specific banks that underwrite residents differently:

• Use your actual IBR payment (or sometimes $0 for deferred/IBR loans)
• No private mortgage insurance (PMI) even with <20% down
• 0–10% down payment accepted
• Account for future physician income in underwriting

This changes the game. Using $262/month IBR rather than $3,200/month imputed transforms your DTI calculation from impossible to workable.

Banks with strong physician mortgage programs:

• Laurel Road
• BMO Harris
• First Horizon
• Regions Bank
• Truist
• Fifth Third

Not all programs accept residents — some require attending status. Verify residency eligibility before wasting time on an application.

The Rent vs Buy Math for Residents

Whether buying makes financial sense depends on three factors: how long you'll stay, local housing prices, and transaction costs.

Transaction costs are the real killer

Buying a home means paying 3–4% in closing costs upfront and 5–7% in transaction costs when selling (real estate commissions, fees). On a $400,000 home, that's $32,000–44,000 in total transaction friction.

A resident who buys in year 1 and sells in year 4 needs home appreciation to cover those costs before breaking even. Most residents aren't staying put that long.

Break-even timeline example:

• Purchase price: $400,000
• Transaction costs (buy): $14,000 (3.5%)
• Transaction costs (sell): $24,000 (6%)
• Total friction: $38,000
• Annual appreciation needed to break even in 4 years: ~2.5% annually

In markets with strong appreciation (parts of the South, Midwest, some metros), this math works. In flat or declining markets, you're selling at a loss.

The monthly payment comparison

Renting: $1,400/month, no maintenance, no property tax, full flexibility

Buying ($400,000 home, 5% down, 6.8% rate, physician loan):

• Principal + Interest: $2,517/month
• Property tax (1.2%/year): $400/month
• Homeowners insurance: $150/month
• Maintenance/repairs (1%/year): $333/month
• Total: ~$3,400/month

Monthly cost to own vs rent: $2,000/month more

That $2,000/month difference parked in a high-yield savings account for 4 years = ~$100,000. Home equity from 4 years of payments on a $400K loan at 6.8%? About $28,000.

Renting wins on monthly cash flow by a significant margin. The only scenario where buying wins is strong appreciation or a very long stay.

When Buying During Residency Makes Sense

Strong case for buying:

• You're in a 5–7 year program (general surgery, neurosurgery, orthopaedic surgery) and won't move for fellowship
• You're in a lower cost-of-living market where rent and home prices are both reasonable
• You have a dual-income household with a working partner
• You genuinely plan to stay in the city after training (grew up there, partner's career is rooted there)
• Local housing market has consistent appreciation

Weak case for buying:

• 3-year residency with uncertain fellowship location
• Very high cost-of-living city (Boston, NYC, SF)
• You'll be solo-income on a resident salary
• You're unsure about your attending position city

What About Investing the Down Payment Instead?

A $20,000 down payment (5% on $400K) invested in index funds during residency at 8% annual return for 4 years = ~$27,000. Home equity from 4 years of payments on the same $400K home at 6.8% = ~$28,000 in equity.

Nearly identical returns. But here's the difference: the investment is liquid, requires zero maintenance, and follows you wherever your career goes. Home equity sits illiquid until you sell.

If You Do Buy: Physician Loan Checklist

1. Verify the lender uses your actual IBR payment — not 1% of balance. Get this in writing before proceeding.
2. Confirm residency eligibility — not all physician programs accept PGYs.
3. Calculate your realistic DTI with IBR payment + estimated mortgage payment + other debts. Stay under 43%.
4. Budget for maintenance — 1% of home value annually ($4,000/year on a $400K home) is realistic. Older homes often run 1.5–2%.
5. Consider a longer fixed rate — 30-year fixed gives maximum flexibility if your timeline changes. Don't take a 5/1 ARM betting on refinancing.
6. Don't deplete emergency fund for down payment — you need 3–6 months of expenses accessible. Better to put down 5% and keep $15,000 in savings than to put 10% down and have zero liquidity.

Frequently Asked Questions

Do student loans on IBR count against mortgage DTI? For conventional loans: yes, lenders impute 1% of balance as monthly debt regardless of actual IBR payment. For physician loans: lenders typically use your actual IBR payment (or $0 if in deferment). Physician loans are the path for most residents.

Can I get a physician mortgage without an attending contract? Some lenders require a signed attending contract. Others approve residents based on their expected income trajectory. Shop multiple lenders — requirements vary significantly.

Should I buy in my residency city if I grew up there and want to return? This is one of the stronger cases for buying. If you're confident you'll return after fellowship and attending placement, buying establishes ownership and builds equity through training. Run the 4–8 year break-even math for your specific market.

How does a house affect my IBR payment? It doesn't directly — IBR is based on AGI, not assets. A mortgage payment doesn't reduce AGI. If you itemize deductions (likely if you have a mortgage), your AGI may decrease slightly, which marginally lowers IBR.

What credit score do I need for a physician mortgage? Most require 680–720+. Some lenders go as low as 660 for strong applicants. Build and maintain credit throughout residency — pay all cards in full monthly.
