The quick read: How you finance a medical office building depends on who occupies it, not on the property type alone: an SBA 504 or 7(a) loan paired with a private lender's first mortgage is available only when the borrower's own practice occupies the space, while an investor buying a multi-tenant or hospital-anchored medical office building competes for bank, life-company or CMBS capital priced off the tenant's credit and remaining lease term, with no SBA path available at all.

How do you finance a medical office building?
Financing a medical office building starts with one question to settle before any other: does the buyer's own practice occupy the building, or is it being bought as a leased investment? That single fact sorts the deal into SBA-eligible owner-occupied financing on one side, and conventional bank, life-company or CMBS investment financing on the other.
A physician group buying its own clinic building can pair an SBA 504 or SBA 7(a) loan with a private lender's first mortgage, because the practice itself occupying the space is exactly what SBA's real-estate rules require. An investor buying a multi-tenant medical office building, or a building anchored by a hospital or health-system lease, has no SBA path at all - the program excludes "speculation or investment in rental real estate," according to the SBA's 504 loan program page - and instead competes for bank, life-company or CMBS capital priced primarily off the tenant's credit and the lease term remaining, not the SBA's occupancy math. Both routes are laid out lender by lender below.
Medical office loan types, lender by lender
The table below separates medical office financing into the five paths that actually apply, because the SBA's owner-occupancy rules only ever govern two of them: whichever lender type competes for a deal is decided first by who occupies the building, and only after that by the property's condition or location.
Table: Medical office building financing paths, September 2026
| Ownership / occupancy | Lender types | Rate basis | Recourse | Amortization / term |
|---|---|---|---|---|
| Owner-occupied practice (SBA 504) | CDC second mortgage plus a private lender's first mortgage | CDC debenture "pegged to an increment above the current market rate for 10-year U.S. Treasury issues" (10-year Treasury: 4.96%, FRED DGS10, Sept. 22, 2026); first mortgage priced separately by the private lender | Recourse; excludes "speculation or investment in rental real estate" (SBA 504 program page) | 10-, 20- or 25-year maturity terms are available (SBA); the first mortgage's term is set separately, confirm in the term sheet |
| Owner-occupied practice (SBA 7(a)) | An SBA 7(a) lender | Variable-rate loans are capped at the base rate (the prime rate, 7.00%, FRED DPRIME, Sept. 21, 2026, or an optional peg rate) plus a size-tiered spread up to 6.5% (SBA) | Recourse | Up to 25 years, including extensions, for a loan used to acquire or improve real property (SBA) |
| Investor-owned, multi-tenant MOB | Bank, life company or CMBS conduit | Priced off in-place income, rent-roll diversification and tenant credit; no medical-office-specific rate, spread or LTV figure found on an allowlisted, dated source today | Ask each lender whether the loan is full, partial or non-recourse, and which carve-outs apply | Set per loan; confirm in the term sheet |
| Hospital-anchored MOB | Life company, CMBS conduit or bank | Priced primarily off the health-system tenant's credit and the lease's remaining term; no medical-office-specific rate or spread figure found on an allowlisted, dated source today | Ask whether the anchor lease and tenant credit support non-recourse terms | Set per loan; ask how the anchor lease's remaining term changes amortization |
| Cash purchase, financed later | Any of the routes above, once the building has an operating history | Not a separate rate - a refinance into one of the rows above, underwritten on the same basis | Depends on the route chosen at refinance | Depends on the route chosen at refinance |
No allowlisted, dated source states a single loan-to-value, DSCR or debt yield figure specific to medical office lending. The closest published anchor, across every commercial property type rather than medical office alone, is CBRE's Q2 2026 lending data: average commercial loan-to-value was 59.6%, down from 60.8% a year earlier, and the average debt service coverage ratio was 1.43x, up from 1.34x, with commercial mortgage spreads narrowing 21 basis points year-over-year to 204 bps and the average interest rate at 5.7%, according to CBRE's Q2 2026 commercial real estate lending release published August 3, 2026. Treat that as a cross-property benchmark, not a medical-office-specific number.
How does tenant credit change medical office loan pricing?
Tenant credit changes medical office pricing because a lease to a hospital or health system reads to a lender like a corporate-credit instrument, while a lease to a private practice or small physician group reads like ordinary operating-business risk. Ask each lender how that difference moves its leverage, recourse and willingness to quote the deal.
The mechanism is the same one that prices any credit-leased commercial building: a longer weighted average lease term behind a stronger tenant lets a lender underwrite the lease rather than the real estate, so ask each life company, CMBS conduit and bank how it weighs a health-system anchor lease against a rent roll of independent practices. Investment in the sector has risen overall: U.S. medical outpatient building investment "surged 24% YoY to $2.7B in Q2 2026 as record rents and stable cap rates drive MOB market stability," according to CBRE's medical outpatient building figures, published August 17, 2026. No allowlisted, dated source breaks that appetite down by tenant type into a specific rate or leverage spread, so this page states the mechanism rather than a number.
What SBA programs finance an owner-occupied medical office building?
SBA 504 and SBA 7(a) are the two federal programs that finance a medical office building, and both apply only when the borrower's own practice occupies the space under SBA's published occupancy thresholds, not when the building is bought purely as a leased investment. Clearing that occupancy test is the gate every other term in this section sits behind.
Under 13 CFR 120.131, a borrower financing an existing building "may permanently lease up to 49 percent of the Rentable Property if the Borrower permanently occupies and uses no less than 51 percent," while a borrower financing new construction must permanently occupy at least 60 percent, may permanently lease up to 20 percent, and must plan to occupy the remaining space within ten years. The same section extends the rule to a practice that holds its building through a separate real-estate entity: "If the Borrower is an Eligible Passive Company which leases 100 percent of the space of the existing building to one or more Operating Companies, the Operating Company, or Operating Companies together, must follow the same rules set forth in this paragraph." A physician group that owns its clinic building through a holding entity and leases 100 percent of it to its own practice can still qualify, as long as the practice itself clears the 51 percent (existing building) or 60 percent (new construction) occupancy threshold.
On the pricing side, the SBA 504 debenture is fixed and "pegged to an increment above the current market rate for 10-year U.S. Treasury issues" - the 10-year Treasury was 4.96% as of September 22, 2026, per FRED - with 10-, 20- or 25-year maturity terms and a program maximum loan amount of $5.5 million, all per the SBA's 504 program page (read September 24, 2026). SBA 7(a) real-estate loans run up to 25 years including extensions, and a variable 7(a) rate is capped at the base rate - the prime rate, 7.00% as of September 21, 2026, per FRED, or an optional peg rate - plus a spread the SBA sets by loan size: base rate plus 6.5% on loans of $50,000 or less, plus 6.0% from $50,001 to $250,000, plus 4.5% from $250,001 to $350,000, and plus 3.0% above $350,000, according to the SBA's 7(a) terms and conditions page, read September 24, 2026. Neither program applies once the practice stops occupying the majority of the building.
What funds an investor-owned, multi-tenant medical office building?
A multi-tenant medical office building bought as an investment, with several independent practices leasing space rather than one occupant owning it, is financed the same way a diversified multi-tenant general office building is: by a bank, a life company or a CMBS conduit, sized off the rent roll's in-place income rather than any SBA occupancy rule.
The lender-type dynamics are close enough to general multi-tenant office underwriting that the leverage, recourse and amortization mechanics covered in YieldStack's overview of office financing options apply directly - rent-roll diversification, staggered lease expirations and tenant-by-tenant credit quality move proceeds the same way they do in a non-medical office building. What differs is the tenant pool itself: a medical office building's tenants are healthcare practices whose leases often carry tenant-improvement costs specific to clinical space, and a lender underwriting the rent roll is reading each practice's own payment history and specialty mix rather than a single corporate credit. No allowlisted, dated source publishes a medical-office-specific loan-to-value or debt-yield figure separate from the general commercial anchor cited above, so this section describes the mechanism rather than asserting one.
What funds a hospital-anchored medical office building?
A hospital-anchored medical office building - one where a hospital or health system is the anchor tenant on a long-term lease - can draw life-company, CMBS or bank lenders that underwrite the health-system lease much like a corporate-credit instrument rather than pure real estate. Ask each lender how much of the loan it will size off that lease.
The remaining lease term behind the health-system anchor is a key variable, the same way it matters for a single-tenant, credit-leased office building generally: a longer remaining term supports more aggressive proceeds and a lower recourse requirement, and a lease approaching its expiration reverts the building toward being priced like a diversified multi-tenant deal. Investment activity in the medical outpatient sector overall surged in Q2 2026, with cap rates described as stable, per CBRE's medical outpatient building figures cited above, though no allowlisted source breaks lending terms out by anchor-tenant type specifically. A borrower financing a hospital-anchored building should ask life-company, CMBS and bank lenders alike to quote the same anchor lease before assuming which one will lead.
How do you get lenders competing for a medical office loan?
You get lenders competing for a medical office loan by putting one complete file - occupancy status, the lease or leases in place, tenant credit, and which SBA or conventional path actually applies - in front of several lender types at once, rather than assuming which program fits before anyone has priced the deal.
That is the work YieldStack does. YieldStack is a commercial mortgage brokerage, not a lender. A borrower completes a 5-minute submit, the deal is presented to lenders whose programs fit it from a catalog of 20,000+ loan programs, and the median offer in under an hour, from an institutional lender, is the starting point for negotiation, not the end of it. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing. Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
Whether the right first move is an SBA 504 application, a life-company quote on a hospital-anchored lease, or a bank term sheet on a multi-tenant rent roll is exactly the kind of question that gets clearer once more than one lender type has actually priced the file. See YieldStack's medical office financing overview for the program types behind this page, or compare how different lender types might read your building's occupancy and tenant mix in the lender-match tool before you shop it to any one of them.
The bottom line
How you finance a medical office building comes down to occupancy first, lender type second: an owner-occupied practice can pair SBA 504 or 7(a) financing with a private lender's first mortgage under the occupancy thresholds in 13 CFR 120.131 (51% for an existing building, 60% for new construction), while an investor-owned multi-tenant building or a hospital-anchored building has no SBA path and instead competes for bank, life-company or CMBS capital priced off tenant credit and remaining lease term. No allowlisted, dated source publishes a medical-office-specific LTV, DSCR or debt-yield figure; the closest published anchor is CBRE's blended commercial figure of 59.6% LTV and 1.43x DSCR as of Q2 2026, a benchmark to compare against, not a medical-office number. Confirm occupancy status first, then put the file in front of the lender types that actually apply.
