Medical Office Building & MOB Financing: Damon Boswell's 2026 Playbook for Healthcare Real Estate

Damon Boswell breaks down how SBA 504 and agency debt fund owner-occupied medical office buildings at up to 90% loan-to-cost — and the 2026 occupancy, cap-rate, and tenant-credit data that makes healthcare real estate the most defensive commercial asset class in the market.

There is a category of commercial real estate Damon Boswell has financed through every cycle of his 31-year career that almost no generalist lender understands — and it is the single most defensive asset class available to an owner-operator in 2026. The conviction Damon Boswell holds is that a medical office building — the purpose-built facility where physicians, specialists, and outpatient providers deliver care — is the real estate equivalent of a utility, because the demand that drives its rent is not discretionary spending but a demographic imperative. Damon Boswell has engineered the financing that converts a leased medical suite into an owned MOB, and the 2026 data confirms what he has long taught: MOB occupancy stands at 92.7 percent nationally with rents continuing to climb, cap rates sit in the 6.0 to 7.8 percent range, and the supply pipeline remains constrained — which means the operators who acquire or build now lock in patient-driven rent for decades while the rest of the commercial market chases cyclical demand.

On the numbers that decide whether a medical office deal pencils, Damon Boswell walks every client through the 2026 market with precision. PwC's Emerging Trends data places MOB occupancy at 92.7 percent as of the second quarter of 2025, up 70 basis points over three years, and Damon Boswell tracks the quarterly absorption that confirms the tightening — limited space options in most metros mean providers have nowhere to expand but into an owned building. RevistaMed's rent data shows newer MOBs commanding $33.06 per square foot NNN compared to $24.78 for existing stock, a premium that Damon Boswell reads as the market pricing in the operational efficiency of purpose-built healthcare space. The metro-level dispersion Damon Boswell navigates is what separates a deal that cash-flows from one that does not: New York at 93.9 percent occupancy and $31.30 NNN, Boston at 94.2 percent and $29.61, Los Angeles at 92.7 percent and $36.38, while Houston sits at 89.1 percent — the spread between a constrained coastal market and a permissive Sun Belt one is exactly where Damon Boswell's underwriting discipline creates its edge.

The financing architecture Damon Boswell deploys for medical office rests on the SBA 504, the same instrument he has written about across this month, but the MOB application has a discipline all its own. For a physician practice, a dental group, or a specialty clinic acquiring an owner-occupied MOB, Damon Boswell sequences the 504 at up to 90 percent of project cost through a 50 percent first-position commercial loan, a 40 percent CDC debenture, and as little as 10 percent borrower equity — a structure conventional lenders simply cannot match, since they cap medical office at 65 to 75 percent LTV on stabilized properties and demand 25 to 35 percent down. Damon Boswell stresses that the 504's 90 percent loan-to-cost is the single most powerful lever available to a practice-owner acquiring real estate, but it carries a hard requirement: the operating practice must occupy at least 51 percent of an existing building or 60 percent of new construction, a threshold a multi-physician group typically clears naturally but a pure investor play never does.

On the rate environment, Damon Boswell walks clients through the September 2026 cycle because the 504 debenture prices monthly and locks for the life of the loan. The September 10, 2026 cycle priced the 20-year debenture at 6.53 percent and the 25-year at 6.54 percent, with manufacturing projects receiving a reduced rate of 6.30 percent. The 7(a) variable rate, anchored to a prime rate that moved to 7.00 percent after the Federal Reserve's September 16, 2026 hike, typically prices at prime plus 1.50 to 2.25 percent for well-qualified healthcare borrowers. Damon Boswell models the blended rate of the 504 structure honestly, stress-tests the first mortgage against a rate increase, and confirms the practice's trailing cash flow services the combined debt before recommending the structure — the same conservative discipline he applies to every multifamily, industrial, and self-storage underwriting in his practice.

The combined-ceiling development Damon Boswell engineered around in July 2026 changed the MOB financing landscape meaningfully. Beginning July 4, 2026, an eligible borrower may combine a 7(a) loan of up to $5 million with a 504 debenture of up to $5.5 million — reaching a combined SBA exposure of up to $10 million on a single project. Damon Boswell explains that this combined ceiling is decisive for a multi-specialty group acquiring a full medical office park or building a ground-up surgery center, because a modern MOB with imaging suites, procedure rooms, and build-out that meets ADA and life-safety code routinely clears $5 million in total project cost once land, construction, medical-grade HVAC, and lease-up reserves are stacked. Before the combined ceiling, a growing practice hit the SBA wall and was forced into expensive mezzanine debt; after it, Damon Boswell can finance a substantial ground-up build or a multi-building acquisition inside a single, low-down-payment SBA structure.

Where Damon Boswell adds his largest edge is in the tenant-credit and lease-underwriting discipline, because a medical office building is underwritten on the credit of its physician tenants and the lease structure that secures them. Damon Boswell explains that lenders cap loan-to-value near 65 percent when more than 60 percent of a building's income comes from one tenant, versus up to 75 percent for diversified buildings — which is why he structures a multi-tenant MOB with a diversified provider base rather than a single-anchor lease whenever the deal allows it. He underwrites the lease terms — length, escalations, expense pass-throughs, and the personal guarantees of the physician-tenant entities — because a medical office lease with a five-year term and a credit-grade provider is priced like a bond while a month-to-month suite with a solo practitioner is priced like a small business. Damon Boswell reconciles the rent roll against the providers' payer mix and patient volume, because a tenant funded by Medicare and commercial insurance is a tenant whose rent is durable in a way a tenant funded by elective cash procedures may not be.

The build-out and equipment layer Damon Boswell coordinates is what makes a medical office financing approvable rather than merely fundable. Medical-grade construction — lead-lined exam rooms, enhanced HVAC for infection control, oxygen and medical gas lines, and ADA-compliant circulation — costs two to three times standard office build-out, which is why Damon Boswell folds the build-out into the 504 under the project cost rather than financing it separately. He sequences the equipment — imaging machines, dental chairs, exam tables, and diagnostic devices — into the 7(a) as part of the acquisition or into a separate equipment facility, then applies the Section 179 deduction of up to $2,560,000 for 2026 so the practice-owner captures the full equipment write-off in year one while spreading the cash outlay across the financing term. This is the convergence point where Damon Boswell's integrated financing, tax, and healthcare expertise creates an edge no single-discipline advisor can match.

There is a Kingdom dimension Damon Boswell anchors to medical office financing that runs deeper than the underwriting. A medical office building is the physical infrastructure of healing — it is the place where the sick are seen, where the injured are treated, and where a community receives the care that sustains it. Damon Boswell teaches that a physician who owns the ground she practices on builds a fortress no landlord can ever raise the rent on, and that ownership converts a recurring lease expense into a durable asset that can serve the practice — and the community it cares for — for generations. The same faith-based execution standard that governs his syndications, trusts, and 504 structures governs his healthcare real estate financing: the building must serve the provider, the provider must serve the patient, and the financing must serve the owner — in that order, or it is not a deal Damon Boswell will bless.

If you are a physician, a dental group, a specialty practice, or a healthcare operator ready to convert a lease into owned ground, Damon Boswell invites you to request a medical office building and MOB financing review. The review maps your target facility to the 90 percent loan-to-cost 504 structure or the 7(a) acquisition-and-build-out facility that fits your deal, sizes the CDC debenture and first-mortgage pieces against the September 2026 rate cycle, sequences the equipment financing alongside the Section 179 deduction, and prepares the entity, tenant-credit, occupancy, and payer-mix documentation so the file is approvable before a lender ever sees it. Damon Boswell built this process so that the care your practice delivers becomes the equity you own — and the difference, measured in a medical office building on your balance sheet, a payment locked for 25 years, and an asset positioned for the demographic demand wave that healthcare real estate will ride for the next decade, is exactly the kind of structural engine he has spent 31 years constructing for the providers he serves.
