Most physician-mortgage content assumes you're buying an existing home. But a meaningful share of doctors, dentists, and pharmacists — especially those relocating for an attending job or growing into a forever home — end up building instead. The product that gets you there is a physician construction loan, and it isn't simply a physician purchase loan with a longer timeline. The structure is different, the rate-lock decisions are different, and the lender list is shorter.
Here's what the 2026 version actually looks like, what to choose between the two main structures, and the four physician-specific wrinkles that catch borrowers off guard.
What a physician construction loan is
A physician construction loan combines two products: a short-term construction loan that funds the build in stages, and a long-term permanent mortgage that takes over when the home is finished. As with the purchase-side physician product, the appeal is no PMI, low-to-zero down payment, and underwriting that respects an employment contract instead of two years of tax returns.
Typical 2026 features:
- LTV up to 100% on loan amounts under roughly $750K, with the down-payment ladder rising at $1M / $1.5M / $2M+, mirroring the purchase-side jumbo physician ladder.
- Eligibility: MD/DO/DPM and DDS/DMD at most programs. CRNAs, NPs, PAs at a subset. Pharmacists are included by fewer construction-loan lenders than purchase-loan lenders — confirm this before you fall in love with a plot.
- Draws during construction tied to inspections and percent-complete.
- A licensed general contractor, a fixed-price contract, and a contingency reserve (often 5%–10%) are almost always required.
- The home must be your primary residence — investment builds and most second homes are out.
OTC vs. two-close: the structural fork in the road
There are two main flavors of physician construction loan. Picking the wrong one in this rate environment can cost real money.
One-time close (OTC), a.k.a. construction-to-permanent. You close once, before the foundation is poured. One set of closing costs. Your permanent-loan interest rate is locked from day one, often for 12 months or longer. The trade-off: the lender is taking 12+ months of rate risk on your behalf, so the rate is typically 0.125%–0.375% higher than a same-day purchase quote, and float-down options are limited.
Two-time close. You take out a short-term construction loan, then refinance into a permanent physician mortgage when the home is complete. Two sets of closing costs, two underwrites, and your permanent rate is not locked at the start — you reprice when the build finishes.
The rule of thumb most physician builders should write on a sticky note:
- If you expect rates to be flat or rising during your build window, OTC wins. The locked rate and one closing-cost stack are worth the small day-one premium.
- If you expect rates to fall meaningfully (say, 50+ bp) during your build, two-close wins, because you reprice at completion into a better market.
In May 2026, with the 30-year fixed at 6.37% (up from 6.30% the prior week), forecasts clustered at 5.9%–6.5% by late summer, and Basel III phase-ins keeping the physician spread sticky, the OTC structure has a slight edge for most builders right now. That said, if your timeline runs 14+ months and your gut says rates will be a half-point lower at completion, two-close keeps that optionality open. Ask any OTC lender about their float-down policy — some allow one free downward re-lock if rates drop materially before final close.
Four physician-specific wrinkles
1. The lender list is short. Many of the biggest physician-mortgage banks don't offer construction. Active 2026 names include Synovus (OTC), Liberty FCU, First Horizon, Truist in some footprints, plus a handful of regional banks and credit unions. Plan on 2–3 quotes instead of the usual 5.
2. Contract income still counts, but the close date matters more. The contract-based qualification that lets attendings close before the first paycheck applies here too, but the build's projected completion date becomes the operative date. If you're a resident finishing in June 2027 and the home delivers in May 2027, that works. If the build is going to deliver six months after your contract start, expect tighter cash-reserve underwriting on the construction side.
3. Student-loan DTI now has a July 1 wrinkle. The federal Repayment Assistance Plan (RAP) goes live July 1, 2026. New borrowers using IDR must use RAP, and payments run 1%–10% of AGI with no cap. Lenders are increasingly pre-underwriting projected RAP payments on construction files because the loan won't close for 12+ months — well past July 1. On a high-AGI two-physician household with $400K of student debt, that can swing qualifying purchase price by $50K–$150K. Get your DTI math in writing under RAP assumptions, not your current SAVE/PAYE payment.
4. The builder's preferred lender may not be your best lender. Builders frequently bundle incentives — closing-cost credits, rate buydowns — through an in-house or affiliated mortgage company. Those incentives are real, but they often steer you off the physician program and back to a conventional construction product with PMI or a 10%–20% down requirement. Quote both paths side by side and compare the all-in five-year cost, not just the day-one rate.
A 2026 shopping playbook
A simple sequence that keeps the moving parts honest:
First, decide your structure — OTC or two-close — based on your build timeline and rate view. Then shop 2–3 physician construction lenders, plus the builder's preferred lender for comparison. Get every quote on the same loan amount, the same lock length, and the same draw schedule. Ask each lender, in writing, three questions: how they treat projected RAP payments for July 1 and after; whether they offer a float-down during the lock; and what their extension fee looks like if the build runs over. Then compare the four numbers on the Loan Estimate — rate, total closing costs, lender credits, and prepaids — exactly the way you'd compare a purchase quote.
A physician construction loan is a great product when the structure fits. Pick the structure first, then the lender — not the other way around.
