Commercial real estate financing for medical office buildings

Commercial real estate financing for medical office buildings is capital structured to purchase, refinance, or build out clinical space, sized around a practice's collections and payer mix rather than a generic tenant's rent roll. A medical office carries higher build-out costs than standard office space — plumbing for exam rooms, lead-lined walls for imaging, backup power for equipment — and lenders underwrite the practice's revenue as much as the property itself. That distinction is the entire game: get the occupancy structure and the financials right before you shop rates.

Why commercial real estate financing matters for medical office buildings

A bank underwriting a retail strip mall looks at market rent comps. A bank underwriting a medical office building looks at your practice's deposits, your payer mix, and whether your specialty even holds resale value in that building if you leave. Physical therapy suites, imaging centers, and surgical centers are often classified as special-purpose real estate — which means fewer buyers if the practice fails, and lenders price that risk into the down payment.

The SBA 504 program is the most common path for owner-occupied purchases because it fixes long-term rates on the second mortgage, but it requires the practice to occupy at least 51% of the building. Lease out the other 49% to a pharmacy or a specialist group and the math still has to clear that line, or the deal falls out of 504 eligibility entirely. That single rule shapes almost every medical office purchase decision made in 2026.

Determine your occupancy structure

Decide how much of the building your practice will actually use before you talk to a single lender. This is the fork in the road between SBA 504, SBA 7(a), and conventional financing.

• Confirm your practice occupies 51% or more of the square footage for SBA 504 eligibility
• Map out any planned subtenants (specialists, pharmacy, lab) and their lease terms
• Check local zoning and, in Certificate of Need states, whether your specialty requires CON approval before occupancy
• Decide if you're buying solo or as a multi-partner group, which changes guarantor structure
• Get a written occupancy plan a lender can underwrite against, not a verbal estimate

Audit your practice financials before you apply

Lenders financing a medical office want two to three years of practice financials, not just a personal credit pull. Clean this up before you submit anything.

• Pull two to three years of tax returns and interim P&Ls for the practice entity
• Reconcile collections against gross charges to show real payer-adjusted revenue
• Separate personal draws from practice operating expenses on the books
• Document any recent payer mix shifts (Medicare, commercial, cash-pay) that affect projected revenue
• Fix negative-balance days or NSFs on business bank statements — funders read these closely regardless of loan type

Price out true medical build-out costs

Medical build-out runs well above shell office construction because of plumbing, ventilation, and equipment-specific power requirements. Get real contractor bids before you size the loan.

• Get itemized bids for plumbing (exam sinks, sterilization) and dedicated HVAC zones
• Price lead-lined walls or shielding if imaging or radiology is part of the build
• Confirm electrical capacity for diagnostic or surgical equipment before finalizing floor plans
• Add ADA compliance costs specific to medical corridors and exam room clearances
• Budget contingency of 10-15% on top of contractor bids — medical build-outs run over more often than standard office fit-outs

Compare SBA 504, SBA 7(a), and conventional CRE loans

Once occupancy and cost estimates are locked, compare structures side by side instead of taking the first term sheet.

• Request 504 term sheets from at least two Certified Development Companies for rate comparison
• Ask 7(a) lenders whether they'll finance the building and working capital in one loan
• Get a conventional bank CRE quote as a baseline, even if you expect to go SBA
• Confirm prepayment penalty structure on any 504 debenture — 504 has a declining prepayment penalty over 10 years
• Ask each lender directly how they classify your specialty (standard vs. special-purpose) since that changes the down payment

Separate your real estate financing from your equipment and working capital

Blending equipment financing or working capital into the real estate loan usually costs more over the life of the deal than financing each piece on its own terms. This is where a practice's cash-flow timeline matters more than the building's appraisal.

Medical practices scaling into a new building often need a working capital bridge for staffing, supplies, and marketing before the new location generates full collections. Working capital loans for medical aesthetics practices are structured around exactly that kind of revenue ramp, separate from the real estate note. If you're managing the build-out itself, working capital loans for construction contractors fund the general contractor's draw schedule without touching your CRE terms.

• Get equipment financing quoted separately — equipment lenders often beat blended SBA equipment riders
• Line up a working capital facility for the 60-90 day period before the new office hits full collections
• Keep the real estate note's amortization schedule isolated from short-term draws
• Confirm your CRE lender allows subordinate working capital debt without triggering a covenant default

Prepare your credentialing and licensure paperwork

Lenders underwriting a medical office want proof the practice can legally operate in that location before closing. Missing licensure paperwork is one of the most common reasons medical office deals stall in underwriting.

• Confirm state medical facility licensure timeline against your target closing date
• Get payer credentialing (Medicare, major commercial plans) updated for the new address
• Pull any required accreditation documentation (imaging, surgical center) the lender's underwriter will request
• Have your malpractice carrier confirm coverage transfers to the new location before close

Line up a bridge for the gap between earnest money and closing

SBA 504 and 7(a) loans commonly take 60-90 days to close. If your purchase contract has a tighter earnest money deadline, a short-term bridge protects the deposit while the SBA paperwork moves.

Jon Lynch Financial Group structures revenue-based bridge financing with 24-48 hour funding decisions for exactly this gap, keeping the deal alive without renegotiating the purchase contract. Veteran-owned practices working through SBA channels can also review SBA loans for veteran-owned businesses for program-specific eligibility before locking a lender.

• Confirm your purchase contract's earnest money deadline against the SBA lender's stated closing timeline
• Ask the SBA lender in writing for their average days-to-close on medical office deals specifically
• Line up bridge financing terms before you need them, not after a closing date slips
• Confirm the bridge lender allows payoff at SBA closing without an early-termination penalty

Common mistakes medical practices make

• Ignoring the 51% test until underwriting. Practices plan subtenant leases first and discover the occupancy math kills 504 eligibility after they've already signed a letter of intent.
• Pricing build-out like standard office space. A general contractor's shell-office estimate rarely accounts for medical plumbing, shielding, or dedicated HVAC zones — the actual number runs higher.
• Applying for SBA before licensure is settled. Underwriters stall files waiting on state facility licensure or payer credentialing that should have started months earlier.
• Blending equipment financing into the real estate note. It looks simpler upfront but usually costs more over the loan term than financing equipment on its own schedule.
• No bridge plan for the closing gap. Losing earnest money because an SBA closing slipped past a 60-90 day contract deadline is avoidable with financing lined up ahead of time.

FAQ

One last thing

The deal-killer in most medical office purchases isn't the interest rate — it's the timeline mismatch between a 60-90 day SBA close and a 30-day earnest money deadline. Practices that line up bridge financing before they sign the purchase contract keep leverage in negotiations; practices that scramble for a bridge after a closing date slips usually pay more for it and negotiate from a weaker position.
