What is a doctor loan and who qualifies?

A doctor loan (or physician loan) is a specialized mortgage product designed for medical doctors, including residents, fellows, and practicing physicians. Qualification typically requires an MD or DO degree, proof of medical license, and a signed employment contract or residency/fellowship agreement. These loans are offered by specialty lenders who understand physicians' unique financial situations — high student loan debt during training but high earning potential after graduation.

How does the no-PMI benefit work?

Doctor loans waive private mortgage insurance (PMI) for loans up to $1 million, even with a low down payment (as little as 0% to 5%). This is a significant benefit because conventional loans require PMI when the down payment is less than 20%. PMI typically costs 0.5% to 1.5% of the loan amount annually. By waiving PMI, doctor loans can save physicians hundreds of dollars per month.

What is the DTI limit for doctor loans?

Doctor loans typically waive the standard debt-to-income (DTI) limit, which is normally 36% to 43% for conventional mortgages. This is particularly valuable for physicians during residency, who may have high student loan debt (sometimes $200,000+) but relatively low income. The lender evaluates the physician's future earning potential rather than current DTI, making homeownership accessible during training years.

What down payment is required for a doctor loan?

Down payment requirements vary by lender but can be as low as 0% for loans up to the conforming limit, and 5% to 10% for higher loan amounts. Some lenders offer 100% financing up to $1 million. The trade-off is that loans with no down payment may have slightly higher interest rates. However, the absence of PMI often makes doctor loans cheaper than conventional low-down-payment options overall.

Can I get a doctor loan during residency?

Yes, this is one of the key benefits of doctor loan programs. Many lenders offer special underwriting for residents and fellows, allowing them to qualify based on their residency contract and future earning potential rather than current income. Some lenders will count a portion of future income as qualifying income. This enables residents to purchase a home before their attending-level salary kicks in.

How do doctor loan rates compare to conventional rates?

Doctor loan rates are typically very close to conventional mortgage rates — usually within 0.25% to 0.5% of comparable conventional loans. Given that conventional loans require PMI with less than 20% down, the doctor loan is usually cheaper on an all-in basis. Some physicians refinance into a conventional loan later to take advantage of their improved financial position.

What are the tax benefits of a doctor loan?

The interest paid on a doctor loan is tax-deductible like any other mortgage interest, up to $750,000 of principal (or $1 million for loans originated before December 15, 2017). Since doctor loans often have higher principal amounts, the interest deduction can be substantial. Additionally, the absence of PMI means you are not paying for non-deductible mortgage insurance.

Can a doctor loan be used for investment property?

Doctor loans are primarily designed for primary residences, though some lenders may offer physician loans for second homes or investment properties with different terms (higher rates, higher down payment). However, the most favorable terms — including the no-PMI benefit and DTI waiver — are typically reserved for primary residences where the physician lives or intends to live.

Your doctor loan rate of 6.25% is in line with current market rates for physician mortgages. This is competitive given the flexible underwriting and no-PMI benefits.

Formula

How It's Calculated

Doctor loan monthly payment calculation:

1. Loan Amount = Home Price - Down Payment
2. No PMI (waived for loans up to $1M, LTV <= 100%)
3. Monthly Payment = M = P x [r(1+r)^n] / [(1+r)^n - 1]
   where P = loan amount, r = monthly rate, n = months

Total monthly payment = P&I + (Property Tax / 12) + (Insurance / 12) + HOA

No-PMI savings example:
  $750,000 loan at 6.25% for 30 years
  Without PMI (doctor loan): ~$4,635/month P&I
  With PMI (conventional, 5% down): ~$4,635 + $313 PMI = $4,948/month
  Monthly savings: $313 | Annual savings: $3,756

DTI waiver example:
  Resident making $60,000/year ($5,000/month)
  Monthly debt: $3,000 (student loans + living expenses)
  Monthly P&I: $4,635
  Total DTI: ($4,635 + $3,000) / $5,000 = 152.7%
  Conventional limit: 36-43% -> DENIED
  Doctor loan: DTI waived -> APPROVED
