How On-Campus MOB Financing Works in Seattle
On-campus medical office buildings occupy the strongest position in the healthcare real estate capital stack, and Seattle is among the most compelling markets in the country for this asset class. The metro's major health systems, including UW Medicine, Swedish Health Services, and Providence, have been aggressively expanding their ambulatory care footprints across King and Pierce counties. That expansion is not speculative. It is driven by payer mix, population density, and a deliberate strategic shift to push high-margin outpatient procedures away from acute care settings. When a health system anchors an on-campus or immediately adjacent medical office building under a long-term net lease, it creates the kind of credit profile that institutional lenders compete aggressively to finance.
Within the Seattle metro, on-campus MOB concentration follows health system geography. South Lake Union and Capitol Hill remain the core hospital campus nodes, with UW Medicine's academic medical complex and Swedish's First Hill footprint drawing physician group tenants into adjacent medical office product. The suburban expansion is equally important for capital markets purposes. Bellevue, Redmond, Kirkland, and Renton are absorbing significant outpatient investment from health systems targeting the Eastside's commercially insured, high-income patient population. Shoreline and Tacoma round out the active submarket list for on-campus and campus-adjacent development. Class A occupancy in the 90 to 95 percent range across well-leased assets reflects genuine demand, not temporary market distortion.
The financing logic for this program type centers on lease credit and location certainty. An on-campus MOB leased to hospital-employed physician groups or health system-affiliated imaging and surgical services, under a 10 to 20 year NNN structure with a health system guaranty, is underwritten almost like a bond. Lenders focus on the credit of the guarantor, the remaining lease term at closing, and the degree to which the tenant is mission-critical to the sponsoring health system's care delivery model. In Seattle, where UW Medicine and Swedish carry institutional name recognition and strong balance sheets, that credit conversation tends to go well with life insurance company credit committees.
Lender Appetite and Capital Stack for Seattle On-Campus MOB
Life insurance companies are the most competitive permanent lenders for stabilized on-campus MOB in Seattle. For assets anchored by investment-grade or near-investment-grade health system credit, life company spreads are running in the 125 to 175 basis point range over the 10-year Treasury. With the 10-year in the 4.3 percent range in 2026, that positions all-in rates in the low to mid 5 percent range for the strongest credits, which remains the tightest institutional pricing available in the healthcare real estate sector. Life companies offer 10-year fixed terms with 25 to 30 year amortization, and prepayment is typically structured as yield maintenance or a declining schedule, which matters for sponsors modeling a mid-hold disposition or recapitalization.
CMBS is active for transactions at $10 million and above where the health system anchor carries investment-grade or near-investment-grade credit. CMBS spreads for this program type are running 175 to 250 basis points over, which reflects the additional liquidity and leverage flexibility that securitized debt provides. LTV for life company executions typically ranges from 60 to 70 percent, tightening toward the lower end for longer lease terms and stronger credit. CMBS can stretch to 65 to 75 percent in the right credit scenario. Regional banks, including Banner Bank and Columbia Banking Group, are competing on stabilized assets and offering floating-rate structures indexed to SOFR, currently near 3.6 percent, with spreads in the 150 to 250 basis point range depending on sponsorship and lease profile.
Bridge debt from institutional debt funds enters the picture for on-campus MOB acquisitions with near-term lease rollover, lease-up situations ahead of a permanent takeout, or sale-leaseback transactions where the health system is monetizing owned campus real estate and the new ownership structure needs time to season. Debt fund pricing is wider but execution is faster, and loan structures can be crafted to accommodate the transitional income profile while the sponsor positions the asset for a life company or CMBS refinance.
Underwriting Criteria That Matter in Seattle
Health system credit quality is the primary underwriting variable for this program type, and lenders are doing real credit analysis on the guarantor, not just accepting investment-grade ratings at face value. In Seattle, UW Medicine's status as an academic medical center with state affiliation, and Swedish's position as part of the Providence system, are both understood by institutional credit committees. What lenders scrutinize closely is the lease structure itself: whether the health system guaranty is full-term and unconditional, whether there are any co-tenancy provisions or termination rights that could compromise income certainty, and whether the building's physical configuration is genuinely mission-critical to the tenant's operations.
Building specifications matter more for on-campus MOB than for conventional office, and Seattle's older campus-adjacent stock creates specific underwriting risk. Medical-grade HVAC, reinforced floors for imaging equipment, ADA compliance throughout, and hospital-level electrical capacity are baseline expectations for institutional lenders. Lenders in this market are also attentive to environmental considerations, particularly for older properties near South Lake Union's development-dense corridor, and to seismic compliance given Seattle's risk profile. Properties that have not been updated to current seismic standards can face additional scrutiny or reserves requirements from life companies and CMBS conduits alike.
Typical Deal Profile and Timeline
Realistic on-campus MOB deals in Seattle fall in the $15 million to $75 million range for single-asset transactions, with portfolio and campus acquisitions reaching $200 million or above. Sponsors that compete effectively in this market are typically institutional or institutional-quality operators with prior healthcare real estate track records, the balance sheet to meet net worth and liquidity requirements at 100 percent of loan amount, and the operational familiarity to manage the tenant relationships and building specifications that health system anchors expect. Lenders will want to see the full lease abstract, guaranty language, and building inspection reports early in the process.
A realistic timeline from executed LOI through closing runs 60 to 90 days for a life company permanent loan on a clean stabilized asset, assuming the lease package is organized and the property condition report does not surface material issues. CMBS timelines are similar. Bridge closings can compress to 30 to 45 days for well-prepared sponsors with clean title and environmental. The primary timeline risk in Seattle is third-party report scheduling, particularly for environmental and seismic assessments, where local vendor capacity can create delays in active transaction periods.
Common Execution Pitfalls Specific to Seattle
Seismic compliance is the most underestimated underwriting issue for on-campus MOB acquisitions in Seattle. Sponsors who acquire older campus-adjacent buildings without a clear understanding of the seismic report findings often discover that institutional lenders require significant reserves or upgrades before closing. Engage a seismic engineer before LOI if the building was constructed before current code standards.
Lease abstraction gaps create friction with life company credit committees. Health system master leases and tenant guaranties in this market are often complex documents with embedded termination rights, expansion options, or co-tenancy provisions that are not visible in a simple rent roll summary. Lenders will read the lease. Sponsors who do not have clean lease abstracts prepared will lose time during due diligence.
Overestimating CMBS flexibility on lease rollover concentration is a recurring issue. CMBS conduits are active in this market but they are disciplined on single-tenant concentration risk. A building that is 100 percent leased to one physician group entity, even with a health system guaranty, will face more structural scrutiny than a multi-tenant MOB with a health system anchor and supporting tenants.
Finally, sponsors frequently underestimate the competitiveness of the life company bid process in Seattle. Multiple life companies are tracking health system-anchored assets in this metro, and sponsors who approach only one or two lenders without a structured competitive process are leaving meaningful pricing improvement on the table. Running a disciplined lender solicitation is not optional for deals where basis points matter at scale.
