Most physician-mortgage content is written for a $400K–$700K purchase. That covers the majority of attending physicians in the majority of metros — but not the file we keep getting questions about: a dual-physician household buying in Bay Area, Boston, Manhattan, Seattle, San Diego, or a coastal South Florida ZIP, where the realistic purchase price is $1.4M, $2.1M, or $2.8M. Above the conforming line, "physician mortgage" stops being a single product and becomes a tiered ladder, with rules that change at every step.

The good news: the physician mortgage is, for many of these buyers, the cleanest jumbo path on the market — no PMI, IDR-friendly student loan treatment, and a single underwriting stack that doesn't penalize a thin post-residency asset base. The less-good news: at the top tiers, the program starts to behave more like a traditional bank-portfolio jumbo, and a few specific risks that don't matter at $450K matter a great deal at $1.8M.

The line: where "conforming" ends in 2026

For 2026, the baseline conforming loan limit is $832,750 for a one-unit home. High-cost areas — the metros where the median price historically runs above the baseline — go up to $1,249,125. Anything above those thresholds is, by definition, a jumbo loan.

That matters because most "physician mortgage" calculators and program pages quietly describe the conforming-sized product. The standard 0% down, no-PMI, IDR-friendly file you see in the marketing materials usually maxes out somewhere between $750K and $1M. Above that, the same lender is still willing to lend — but on a different rung of the same ladder, with a different down payment, reserve requirement, and rate.

The ladder: what changes at $1M, $2M, and $3M

Most physician-loan portfolio lenders publish a tiered structure. The specific numbers vary by bank, but the shape is consistent. A representative 2026 ladder looks like this:

The advertised top end is bank-specific. KeyBank's professional program publishes a $3.5M ceiling on this structure; BMO, Fifth Third, Bank of America Doctor Loan, and several regional portfolio lenders publish similar ladders in the $1.5M–$3M range. Some banks will go higher with private-bank relationships layered on top. The point isn't the exact ceiling — it's that the physician-loan benefits taper as the balance grows, in a fairly predictable pattern, and you need to know which rung your file lands on before you write an offer.

Why the jumbo physician loan still wins

Even with the step-ups, the physician program remains compelling at $1M+ for three reasons.

No PMI on lower down payments. A conventional jumbo at 10%–15% down typically requires PMI or a piggyback structure. On a $1.6M purchase at 10% down, the PMI savings alone is meaningful — often $400–$700/mo — preserved over potentially years until the balance reaches 80% LTV.

IDR/RAP-friendly treatment of student loan debt. Conventional jumbo underwriting often uses 1% of the balance, or fully amortized payments, as the qualifying payment. Physician programs are the rare jumbo product that will use the actual income-driven payment — and for a household sitting on $400K–$700K of combined education debt, this is frequently the difference between qualifying for $1.8M and qualifying for $1.2M.

No two-year self-employment history requirement on new-attending W-2s. Conventional jumbo lenders commonly want two years of stable income documentation. The physician program will lend on a signed contract with 60–90 days to first paycheck, even at $1M+ — which is exactly the window in which a new attending might be moving to a high-cost metro.

Where the jumbo physician loan quietly loses

There are three scenarios where the conventional jumbo (or a hybrid) beats the physician product at high balances.

You can put 20% down comfortably and your student loan debt is modest. At 20%+ down with a clean DTI, the no-PMI advantage disappears, and the physician-loan rate premium becomes a recurring cost over the life of the loan. On a $2M file, a 25 bp rate gap is roughly $400/mo for 30 years.

Your income is heavily variable (RVU, 1099, partnership distributions). Some bank portfolio jumbo programs price variable-income files better than their own physician program — odd, but real. Worth quoting both within the same bank.

You want a 7/6 or 10/6 ARM at a price that beats the physician product. The non-bank conventional jumbo ARM market is currently aggressive on rate and origination credits, particularly above $1.5M. For a buyer with high short-term move/refi confidence, that comparison is worth running.

The RAP risk that hits jumbo files hardest

The new Repayment Assistance Plan (RAP) becomes the sole IDR option for new federal Direct Loan borrowers on July 1, 2026 and an additional option for current borrowers. Under RAP, payments are 1%–10% of total AGI, with no payment cap — meaning that for a two-physician household at $600K AGI, the projected RAP payment can run $5,000+/month, an order of magnitude above many current PAYE or SAVE-era payments.

Physician-loan banks have begun pre-underwriting projected RAP payments for borrowers likely to be on RAP at closing. On a $450K file, this often moves DTI but does not break approval. On a $1.8M file already running DTI near the program ceiling, a $4,000/month projected RAP payment can move qualifying purchase price down by $200K–$300K — and that math doesn't show up until late in underwriting.

If you are buying a jumbo physician file in the next 90 days and have federal student loans, get the IDR-vs.-RAP treatment in writing from the lender at pre-approval — not at clear-to-close.

A six-question shopping playbook for spring 2026

Use these in writing with every lender you quote. The first three sort the ladder; the last three sort the lender.

  1. At my purchase price and down payment, exactly which rung of your physician-mortgage tier am I on? Get the down payment, FICO floor, reserve months, and any rate add-on for that rung in writing.
  2. What is your true ceiling on the physician program? Some programs advertise $3M but rarely close above $2.25M without private-bank overlay. Ask for the highest 2026 close.
  3. At my balance, where does your bank's conventional or non-bank jumbo beat your physician product on all-in 5-year and 10-year cost? This is the question that produces the only honest cross-product comparison.
  4. How will my student loans be qualified — IDR, RAP, or fully-amortized — and what changes if I close after July 1?
  5. Reserves: which assets count, at what haircut? Brokerage usually 70%, retirement 60% or zero, crypto typically zero, business and gift funds usually excluded.
  6. What is your concentration / pull-back risk on this product? Portfolio lenders can re-price or suspend the program mid-pipeline; ask for the bank's policy on locked files in that scenario.

Bottom line

At $1M+, the physician mortgage stops being a single product and becomes a ladder. The standard "0% down, no PMI" pitch is largely a story about the bottom rung. The middle and top rungs — where a lot of dual-physician households and high-cost-metro buyers actually live — require a different mental model: tiered down payments, stepped-up reserves, RAP-aware underwriting, and a serious comparison against conventional and non-bank jumbo alternatives.

The product still wins for most buyers in this range. But it wins by a narrower margin, and the cost of choosing the wrong lender or wrong rung is much higher than it is on a $450K file. Get the ladder in writing, run the RAP scenario explicitly, and quote at least three lenders before you write the offer.
