Physician Loans Explained for Houston Medical Professionals

The physician mortgage loan is one of the most useful and least understood financial products available to medical professionals. Most doctors, nurses, and advanced practice providers encounter the concept at some point during training or early career, but the explanation they get is usually incomplete — either oversimplifying it into “a loan that ignores student debt” or making it sound so specialized it might not apply to them. This is my attempt at a clear, honest explanation of what physician loans actually are, how they work in the Houston market specifically, and when using one makes more sense than using a conventional mortgage.

What a Physician Loan Actually Is

A physician mortgage is a conventional mortgage product offered by select lenders that modifies the standard underwriting criteria in specific ways for medical professionals. The core modifications are: waiving the requirement for private mortgage insurance (PMI) on loans with down payments below 20%, excluding or favorably treating medical school debt in the debt-to-income calculation, and accepting a signed employment contract in place of multiple months of pay stubs for buyers who are about to start a new position. These three changes address the three most common barriers that medical professionals face when trying to buy with standard financing.

What physician loans are not: they are not government programs, they are not guaranteed or subsidized, and they are not universally available. The specific terms — which professions qualify, how student debt is treated, what the down payment minimums are, and what the rate premium is relative to conventional financing — vary by lender and change periodically. The name “physician mortgage” is a marketing term applied to a category of products rather than a standardized loan type. Always verify current terms directly with a lender rather than relying on general descriptions, including this one.

Who Qualifies in the Houston Market

Most physician mortgage programs are available to medical doctors (MDs and DOs), dentists (DMDs and DDSs), and veterinarians (DVMs). Many programs have expanded to include advanced practice providers — nurse practitioners, physician assistants, and certified registered nurse anesthetists (CRNAs). Some programs include pharmacists, physical therapists, and other allied health professionals. The qualifying credential matters and varies by lender — a program that covers NPs may not cover RNs, and a program that covers attending physicians may not cover residents at the same income level.

In Houston, where the Texas Medical Center employs over 100,000 people across every medical credential category, the question of who qualifies is practically important. The lenders who offer the most useful programs for Houston medical professionals are the ones who have experience with TMC-area transactions and understand the specific documentation patterns of residents, fellows, and attendings coming through major training programs. Lender selection matters as much as loan product selection.

The Student Loan Treatment

The single most valuable feature of physician mortgage programs for most borrowers is the student loan treatment. Standard conventional underwriting counts all monthly minimum debt payments against your debt-to-income ratio. For a physician with $250,000 in student loans on an income-driven repayment plan that temporarily sets the monthly payment at a low figure, conventional underwriting may still use a higher calculated payment — typically 0.5% to 1% of the total loan balance per month — which can add $1,250 to $2,500 per month to your calculated debt obligations even if your actual payment is $200.

Physician loan programs handle this differently. Many use the actual income-driven repayment payment rather than the calculated payment. Some exclude student loans from the DTI calculation entirely. The practical effect can be $200,000 to $400,000 more in purchase power for a borrower with significant student debt. That difference determines whether a physician can buy in Bellaire or is limited to the outer suburbs on a resident salary.

The Employment Contract Provision

For medical professionals transitioning out of training — residents finishing fellowship, new attendings starting their first hospital position, or practitioners taking a new employer contract — the employment contract provision solves a specific problem. Standard mortgage underwriting requires 30 days of pay stubs from your current employer. If you are closing on a home in June but your attending position starts July 1st, you have no pay stubs from the new job.

Physician mortgage programs allow you to use a signed employment contract in place of those pay stubs, with closing typically required within 60 to 90 days of your start date depending on the program. This matters in Houston’s market because the timeline for TMC fellowship ends and attending contract starts does not line up neatly with the 30-day pay stub requirement. The contract provision is what makes buying during the training-to-attending transition possible without a significant gap in housing or a bridge financing arrangement.

What the Rate Looks Like

Physician mortgage rates are typically slightly above conforming conventional mortgage rates for comparable loan sizes. The premium varies by lender and market conditions but historically runs 0.125% to 0.375% above a comparable conventional loan. On a $600,000 loan, that difference adds roughly $50 to $150 per month compared to a conventional loan at the same term. For most physician mortgage borrowers, that premium is outweighed by the PMI savings on a low-down-payment conventional loan — PMI on a 5% down conventional loan at that balance would typically cost $300 to $500 per month and takes years to eliminate.

The math comparison that matters: a physician mortgage at 0.25% premium with no PMI versus a conventional loan at a lower rate with PMI. Run both scenarios with your actual numbers before deciding. The physician loan is usually better for borrowers putting down 5–10%. It is often not better for borrowers who can put down 20% or more, since that eliminates PMI on a conventional loan while also qualifying for standard conventional rates.
