Physician Loan Mortgage Calculator
Advanced Comparison Settings
This physician loan mortgage calculator helps medical professionals estimate monthly payments on a doctor mortgage: a specialized loan program designed for physicians, dentists, and other medical professionals that eliminates many of the barriers traditional mortgages create for high-earning borrowers with significant student debt. Physician mortgage loans allow you to buy a home with as little as 0-5% down, no private mortgage insurance (PMI) even at high LTV ratios, and student loan debt treated differently in qualifying calculations, benefits that can save doctors $300-$800 per month compared to conventional financing in the early years of their careers. Most new physicians carry $200,000-$300,000+ in medical school debt, which makes qualifying for a conventional mortgage extremely difficult despite high earning potential. Physician mortgage lenders understand that a resident earning $60,000 today will likely earn $250,000-$500,000+ within a few years, and they structure the loan accordingly. Use this doctor mortgage calculator to model your specific scenario: enter your home price, down payment, rate, and student loan balance, and see your estimated monthly payment with and without the physician loan advantages. Whether you're a resident, fellow, attending physician, or dentist, this calculator shows you exactly how a doctor home loan compares to conventional and FHA alternatives.
How to Use the Physician Loan Mortgage Calculator
- Step 1: Enter the Home Purchase Price - Enter the full price of the home you plan to purchase. Physician mortgage loans are available for a wide range of home values, though maximum loan amounts vary by lender, most cap between $1,000,000 and $2,000,000, with some offering up to $3,500,000 for established attendings. As of 2024-2025, the average first home purchase for a new physician is between $350,000 and $600,000, though this varies dramatically by specialty and location. Physicians relocating for residency or fellowship often purchase in a different price range than those buying after establishing a practice. Enter the actual purchase price regardless of amount, the calculator will determine the loan structure.
- Step 2: Enter Your Down Payment - Enter the down payment amount or percentage. The defining feature of physician loans is the ability to put down far less than a conventional mortgage requires, without triggering PMI. Most physician mortgage programs offer three tiers: 0% down (available from many lenders up to $750,000-$1,000,000), 5% down (available up to $1,000,000-$1,500,000), and 10% down (available up to $1,500,000-$2,000,000+). Compare this to conventional loans, which require 20% down to avoid PMI: on a $500,000 home, that's a $100,000 cash requirement versus $0-$25,000 with a physician loan. If you're in residency or fellowship with limited savings, 0% down is one of the program's most valuable features.
- Step 3: Enter the Interest Rate - Enter the interest rate offered by your physician mortgage lender. Physician loan rates are typically 0.125%-0.50% higher than the best conventional mortgage rates for the same loan amount and term, because the lender is taking on additional risk by waiving PMI and accepting low or zero down payments. As of 2024-2025, physician mortgage rates generally range from 6.5% to 7.75% for a 30-year fixed and 5.75% to 7.0% for adjustable-rate options (5/1 or 7/1 ARM). Some lenders offer better rates for higher down payments or for borrowers who maintain checking or savings accounts with them. Rate shopping across 3-5 physician mortgage lenders is essential, rate spreads of 0.50% or more between lenders are common.
- Step 4: Select the Loan Term - Choose between a 30-year fixed, 15-year fixed, or an adjustable-rate option (typically 5/1, 7/1, or 10/1 ARM). The 30-year fixed is the most common choice for residents and early-career physicians who need the lowest possible monthly payment. However, the 5/1 or 7/1 ARM is worth serious consideration if you expect to refinance, relocate, or see a significant income increase within 5-7 years: the lower initial ARM rate can save $200-$400/month during the fixed period. Many physicians who buy during residency sell or refinance within 3-7 years when they move for fellowship or their first attending position, making the ARM a strategically sound choice for that specific timeline.
- Step 5: Enter Your Student Loan Balance and Monthly Payment - Enter your total medical school student loan balance and current monthly payment. This is where the physician loan calculation diverges most from conventional mortgages. On a conventional loan, lenders use either your actual monthly student loan payment or 0.5-1.0% of the total balance (whichever is higher) in your debt-to-income (DTI) calculation. For a doctor with $300,000 in loans, that could mean $1,500-$3,000/month counted against qualifying income, often enough to disqualify the borrower entirely. Physician mortgage lenders handle this differently: most use only the actual payment under your current repayment plan (including $0/month if you're in deferment or on an income-driven repayment plan). Some use a flat percentage as low as 0.25% of the balance. This single difference is often what makes qualification possible.
- Step 6: Enter Your Annual Income - Enter your current gross annual income, including base salary and any guaranteed stipends or signing bonuses. For residents and fellows, this is typically $55,000-$75,000 depending on the program and location. For new attendings, income ranges from $200,000 (primary care, pediatrics) to $500,000+ (orthopedics, cardiology, dermatology). Many physician mortgage lenders allow you to qualify using a signed employment contract: this means you can use your future attending salary to qualify for a loan before you've started the position, as long as you have a signed offer letter showing the start date, employer, and compensation. This is particularly valuable for residents in their final year who are purchasing a home at their attending job location.
- Step 7: Review Your DTI and Payment Comparison - After clicking Calculate, the tool shows three key outputs. First, your estimated monthly physician loan payment including principal, interest, property taxes, and insurance, but no PMI, regardless of your down payment. Second, a comparison payment showing what the same home would cost under a conventional loan with PMI (if applicable) and standard student loan DTI treatment. Third, your front-end DTI (housing cost as a percentage of income) and back-end DTI (total debt including student loans as a percentage of income). Most physician mortgage lenders allow back-end DTI up to 45-50%, compared to 43% for conventional loans, giving you additional qualifying flexibility.
How Is a Physician Loan Mortgage Calculated?
The standard monthly principal and interest payment calculated using the amortization formula.
The total loan amount borrowed (Home Price - Down Payment).
The annual interest rate divided by 12.
The loan term in years multiplied by 12.
The monthly payment formula is identical to any standard mortgage. However, physician loans differ significantly in what is excluded and how qualifying works: they offer 0% down options with no private mortgage insurance (PMI) regardless of the LTV ratio, and they use the actual income-driven repayment (IDR) student loan payment (often $0/month) rather than the standard 0.5-1.0% conventional loan requirement.
Physician Loan Examples with Real Numbers
Example 1 — PGY-3 Resident Buying First Home (0% Down)
Dr. Patel is a third-year internal medicine resident in Columbus, OH, earning $65,000/year. She has $280,000 in student loans on an income-driven repayment (IDR) plan at $0/month during residency. She wants to buy a $340,000 townhome with no down payment. Dr. Patel saves $129/month with the physician loan and, more critically, actually qualifies. The conventional lender would count $2,800/month in student loan payments against her income, pushing her DTI well over 100% and making approval impossible. The physician loan uses her actual $0/month IDR payment, keeping DTI at a manageable 49.1%.
Home: $340,000 · Down Payment: 0% · Rate: 7.0% · Income: $65,000 · Student Loans: $280,000 ($0/mo actual)
Physician Loan Payment: $2,662/mo (DTI: 49.1%) · Conventional: Disqualified ($2,791/mo, DTI: 103%+ due to $2,800/mo student loan estimate).
Example 2 — New Attending Buying with Employment Contract (5% Down)
Dr. Chen has just signed a contract as an attending cardiologist in Charlotte, NC, starting at $420,000/year in three months. He has $310,000 in student loans at $2,100/month on a standard repayment plan. He wants to buy a $650,000 home before starting the position. Dr. Chen's physician loan payment is $727/month higher because he's financing $97,500 more. However, he preserves $103,000 in cash: money he can use to pay down student loans at $310,000 (saving 5-7% interest), fund retirement accounts, build an emergency fund, or invest. For a new attending with substantial student debt, keeping liquidity is often a better financial decision than tying up $130,000 in home equity, even at a slightly higher monthly payment.
Home: $650,000 · Down Payment: 5% vs 20% · Rate: 6.875% · Income: $420,000 · Student Loans: $310,000 ($2,100/mo)
Physician Payment: $4,708/mo (cash needed: $42,000) · Conventional (20% down): $3,981/mo (cash needed: $145,000). Cash Preserved: $103,000.
Example 3 — Dentist with 10% Down (Higher Loan Amount)
Dr. Rivera is an established oral surgeon in Scottsdale, AZ, earning $550,000/year. She has $180,000 remaining in student loans. She wants to purchase a $1,200,000 home with 10% down. At $1.2 million, a conventional loan would exceed the conforming limit and enter jumbo territory: this typically requires 10-20% down, stricter qualifying standards, and higher rates. Dr. Rivera's physician loan provides jumbo-level financing at competitive rates with no PMI, saving her approximately $540/month compared to a conventional jumbo with PMI. Over 10 years, the PMI savings alone total $64,800.
Home: $1,200,000 · Down Payment: 10% ($120,000) · Rate: 6.75% · Income: $550,000
Monthly Payment: $8,155 (no PMI) · PMI Savings: ~$540/mo ($6,480/yr).
Example 4 — Physician Loan ARM vs. Fixed (Resident Planning to Relocate)
Dr. Kim is a PGY-1 emergency medicine resident in Milwaukee, earning $62,000/year. He plans to move for his attending position in 3-4 years. He's buying a $290,000 condo with 0% down and comparing a 30-year fixed vs. a 7/1 ARM physician loan. If Dr. Kim sells before the ARM adjusts (which aligns with his 3-4 year relocation plan), the ARM saves nearly $10,000 in interest and $166/month in cash flow, which is a meaningful saving on a resident's salary. The ARM is the financially optimal choice when the exit timeline is clearly within the fixed period. If plans change and he stays, the ARM carries rate adjustment risk after year 7.
Home: $290,000 · Down Payment: 0% · Income: $62,000 · Fixed Rate: 7.125% · ARM Rate: 6.25%
Fixed Payment: $1,952/mo (P&I) · ARM Payment: $1,786/mo (P&I) · Savings: $166/mo (ARM saves $9,800 in interest over 4 years).
Who Uses a Physician Loan Mortgage Calculator?
Medical residents and fellows buying their first home
Early-career physicians earning $55,000-$75,000 with $200,000-$400,000 in student loans who cannot qualify for conventional mortgages due to DTI limits, using the calculator to see how physician loan student debt treatment makes homeownership possible during training.
New attending physicians relocating for their first position
Doctors transitioning from residency to attending roles who need to purchase a home before receiving their first attending paycheck, using the calculator with their signed employment contract income to determine the home price they can qualify for and the monthly payment they can afford.
Dentists and oral surgeons with high student debt
Dental professionals with $300,000-$500,000+ in educational debt (dental school debt often exceeds medical school debt) who need the physician loan's favorable DTI treatment to qualify for homeownership.
Established physicians comparing physician loan vs. conventional
Attendings with 3-5+ years of practice evaluating whether the physician loan's no-PMI benefit at low down payments still outweighs the slightly higher rate compared to a conventional mortgage with 20% down, using the calculator to run the side-by-side comparison.
Medical couples with dual physician incomes
Dual-physician households with combined student debt of $400,000-$700,000 who need favorable debt treatment on both borrowers' student loans to qualify for a home in a high-cost market, using the calculator to model how physician loan DTI rules handle combined debt loads.
Common Mistakes When Calculating Physician Loan Mortgages
Physician loan programs vary significantly between lenders. Some offer 0% down up to $1,000,000, others cap at $750,000 for zero down. Some lenders offer fixed rates only, while others provide ARM options at lower introductory rates. Margin rates, eligible property types (condos vs. single-family), and which medical degrees qualify (MD, DO, DDS, DMD, DPM, OD, DVM, not all lenders include all specialties) differ across programs. Running the calculator with one lender's terms doesn't represent all your options. Get quotes from at least 3-4 physician mortgage lenders and model each scenario separately.
Physician loans typically carry a 0.125-0.50% rate premium compared to conventional mortgages at the same LTV. On a $500,000 loan, a 0.375% rate premium adds approximately $115/month to the payment. Over 30 years, that's $41,400 in additional interest. The no-PMI benefit often more than offsets this premium in the first 5-10 years, but if you plan to stay in the home long-term and could afford 20% down, the conventional loan may cost less overall. Always compare the total cost (including the rate premium) over your expected holding period, not just the monthly payment with PMI removed.
Just because a physician loan allows you to qualify based on a future attending salary doesn't mean you should maximize the approved amount. A $600,000 home with $4,500/month payments on a $65,000 resident salary consumes over 80% of take-home pay, creating severe financial stress for 2-4 years until attending income begins. The calculator shows what you qualify for, but your budget should be based on what you can comfortably afford during the lowest-income period. A conservative approach is keeping total housing costs below 30% of your current take-home pay, even if the lender approves more.
With zero down payment, you start with zero equity. If the housing market dips even 5-10%, you're immediately underwater, owing more than the home is worth. This creates problems if you need to sell for a relocation (which is common in medicine: fellowship moves, attending job changes). Selling an underwater home requires bringing cash to closing or negotiating a short sale. Even a modest 3-5% down payment provides a small equity cushion and signals financial commitment to the lender. Consider your relocation timeline before choosing 0% down.
Physicians with available savings sometimes default to putting 20% down to "get the best rate." But with student loans at 5-7% interest, every dollar in down payment has an opportunity cost: that same money could pay down high-interest student debt, fund a tax-advantaged retirement account (Roth IRA, 401k), or serve as an emergency fund. The physician loan exists specifically to let you preserve capital. A 5% down physician loan at 7.0% costs slightly more monthly than a 20% down conventional at 6.625%, but the $75,000+ in preserved cash working at 7%+ (whether as debt payoff or investment returns) often produces higher net worth than the mortgage savings.
Physician Loan vs. Conventional vs. FHA - Side-by-Side Comparison
The table below compares a physician mortgage against conventional and FHA options for a $500,000 home purchase by a physician with $280,000 in student loans. All scenarios use 30-year fixed rates at 2024-2025 market levels.
| Feature | Physician Loan (0% down) | Physician Loan (5% down) | Conventional (5% down) | Conventional (20% down) | FHA (3.5% down) |
|---|---|---|---|---|---|
| Down payment | $0 | $25,000 | $25,000 | $100,000 | $17,500 |
| Loan amount | $500,000 | $475,000 | $475,000 | $400,000 | $482,500* |
| Interest rate | 7.125% | 7.0% | 6.75% | 6.625% | 6.50% |
| Monthly P&I | $3,367 | $3,161 | $3,082 | $2,561 | $3,051 |
| PMI / MIP per month | $0 | $0 | $356 | $0 | $221 (life of loan) |
| Total monthly (with tax/ins) | $3,917 | $3,711 | $3,988 | $3,111 | $3,822 |
| Cash needed at closing | ~$12,000 | ~$37,000 | ~$37,000 | ~$115,000 | ~$30,000 |
| Student loan DTI treatment | Actual payment | Actual payment | 0.5-1% of balance | 0.5-1% of balance | 1% of balance |
| Can qualify during residency? | Yes | Yes | Unlikely | Unlikely | Very unlikely |
*FHA loan includes 1.75% upfront MIP rolled into the balance. Key takeaway: the physician loan at 5% down is the sweet spot for most buyers - it costs $277/month less than the conventional loan at the same down payment (PMI elimination outweighs the rate premium), preserves $78,000 more cash than 20% down conventional, and is the only option besides physician 0% down that allows qualification during residency. The FHA loan is a poor fit for physicians due to lifetime MIP and unfavorable student loan DTI treatment.
