If you have read anything about physician mortgages, you have read about the headlines: 0% down, no PMI, student loans treated favorably. What gets less attention — and what quietly derails more closings than rate-shopping ever does — is the cash reserves conversation.
Reserves are the money you have left over after the down payment, closing costs, and prepaid escrows are funded. Lenders measure reserves not in dollars but in months of PITI(A): principal, interest, taxes, insurance, and any HOA. If your full monthly housing payment is $4,000 and you have $24,000 sitting in eligible accounts after closing, you have six months of reserves.
Here is what physician borrowers should understand about that number — what counts toward it, when it gets bigger, and how to plan for it.
The baseline: physician programs are unusually generous
Conventional underwriting typically wants to see 2–6 months of PITI(A) in reserves on an owner-occupied purchase. Physician mortgage programs are notably more flexible. Many lenders advertise 0–6 months required, and several waive the reserves requirement entirely for healthcare borrowers up to roughly $2 million in loan amount.
Why the leniency? Because the same logic that drives the rest of the physician program applies here: lenders treat steady, documented physician income — and the low historical default rate of the demographic — as a partial substitute for thick post-closing savings. A resident with $5,000 in the bank and a signed attending contract worth $320,000 a year is, statistically, a strong credit.
That is the baseline. The interesting part is when the baseline gets flexed.
When lenders ask for more reserves
Five situations reliably push physician-loan reserve requirements upward:
1. Lower FICO scores. A 760+ score will sail through with minimal reserves. A score in the high 600s or low 700s often triggers a 6–12 month reserve ask, in part to offset the credit risk and in part because lenders want a cushion for any income volatility a thinner credit profile might imply.
2. Future-income or pre-employment contract close. Many physician loans allow you to close up to 60–90 days before your first attending paycheck on the strength of a signed contract. In exchange, lenders want enough reserves to cover the gap between the first mortgage payment and the first deposit — typically 3–6 months of PITI, sometimes more. This is the single most common reservation friction point for graduating residents and fellows.
3. Jumbo loan amounts. Physician programs are portfolio loans, but even portfolio lenders tighten as loan size increases. Once you cross roughly $1 million, expect the reserves conversation to shift; over $1.5–2 million, several lenders quietly require six months minimum even on otherwise pristine files.
4. Self-employed, 1099-only, or partnership K-1 income. If your income comes through a private practice, a locum tenens 1099, or a partnership distribution, lenders often substitute extra reserves for the two years of tax returns that physician programs sometimes waive for W-2 employees. A 6–12 month cushion is common.
5. Variable income concentration. If a meaningful share of your qualifying income is from RVU bonuses, call pay, or moonlighting, some lenders ask for additional reserves as protection against income volatility — even when the variable income is well-documented.
What actually counts as reserves
This is where borrowers commonly miscount their cushion. Generally:
- Checking and savings: counted at face value, after subtracting any pending earmarks (down payment, closing costs).
- Brokerage accounts (taxable): typically counted at 70% of current value, to allow for market drawdown.
- Vested retirement balances (401(k), 403(b), IRA): typically counted at 60% of vested balance, and only if the funds are actually accessible to you. Some lenders will not count retirement reserves at all.
- HSA and 529: usually not counted, because withdrawal triggers penalties or restrictions.
- Crypto: most physician-loan lenders do not count it as reserves. A few will count a portion if liquidated to fiat and seasoned.
- Business accounts: generally not counted unless you are documented as the sole owner and provide additional documentation.
- Gift funds in transit: not counted as reserves. Gifts can fund the down payment but do not pad your post-closing position.
A useful exercise: take your reserves on paper, apply the haircuts above, and compare the result to your lender's required months. The number you actually qualify on can be 30–40% lower than your bank statement total.
A realistic target for most physician borrowers
For most W-2 attending or near-attending borrowers buying a primary residence in 2026, a practical reserves target is 3–6 months of PITI(A) post-closing. That gives you:
- Enough to clear typical lender minimums even when underwriting tightens.
- A cushion for the first attending year, where moving costs, license fees, and unexpected expenses pile up.
- Margin if the appraisal forces a higher down payment or if closing costs run high.
Residents and fellows closing on contract income should plan for the upper end of that range — 6 months minimum, more if there is a long gap between closing and the first paycheck.
The 2026 wrinkle: documentation matters more
With the July 1, 2026 federal student loan changes ~7 weeks out and lenders pre-underwriting dual debt-to-income scenarios, documentation completeness — including reserves seasoning — has become the difference between a clean approval and a stalled file.
A few practical moves before submission:
- Season your reserves at least 60 days. Lenders verify two months of statements. A large unseasoned deposit triggers a paper trail request.
- Consolidate before applying. Multiple small accounts complicate verification. Merging eligible reserves into one or two accounts simplifies underwriting.
- Disclose retirement balances even if they are not needed. They often serve as a quiet tiebreaker if the lender wants extra comfort.
- Plan for the post-closing reserve, not just the cash to close. A common borrower error is hitting the closing-cost number on the nose and walking out of escrow with nothing left over — exactly the thing reserves are meant to prevent.
The bigger picture
Reserves are the part of physician underwriting that rewards habits, not income. A borrower who carries six months of expenses in liquid form simply has more options — better rate tier, more lender choice, easier path through an unexpected appraisal cut or a mid-process job change.
The physician mortgage product was designed to forgive a thin balance sheet on day one of an attending career. It is still a forgiving product. But forgiving is not the same as unlimited, and in the spring 2026 environment — where lenders are stress-testing files and the policy ground is shifting — knowing your reserves number, in months of PITI, is one of the highest-leverage moves a physician borrower can make.
