Medical office buildings: refinancing options and considerations

What is the 2026 medical office refinance picture?

Medical office building (MOB) is the property type that has decoupled most from traditional office in the lender options. While conventional office struggles with occupancy, rollover, and concession packages, MOB occupancy in major MSAs sits in the mid-90s and has held through the post-2020 cycle. The structural drivers (aging demographics, growth in outpatient procedures, preference for ambulatory care over hospital-based care) are durable.

The result for refinance: stabilized, well-located MOB with credit tenancy (hospital systems, large physician groups) and on-campus or campus-adjacent positioning refinances cleanly at par. Off-campus MOB with weaker tenancy or short WALT is harder but still meaningfully more refinanceable than equivalent traditional office.

Which capital sources will refinance my MOB?

Medical office financing depends on tenant credit, lease terms, occupancy, property use and the proposed loan. Compare lender underwriting and actual proceeds rather than assuming it receives the best office pricing.

What LTV, DSCR, and debt yield should I expect?

MOB sizing in 2026 is tighter than multifamily but materially better than traditional office. Tenancy quality, WALT, and on-campus positioning are the big drivers of where in the range a deal prices.

Cash-out refi vs. rate-and-term refi: which is realistic?

Cash-out on MOB refis in 2026 is realistic on stabilized assets with strong tenancy where rents have grown and cap rates have held or compressed. The MOB cap-rate move from 2022 to 2024 was meaningfully smaller than the conventional office move, which preserves cash-out math on the strongest assets. A 2018 vintage on-campus MOB bought at a 6.50% cap and now appraising at a 6.75% cap with 5 years of rent growth can often support a small cash-out at 60% LTV after the rate move.

Rate-and-term with a 5% to 15% paydown is the base case for off-campus and weaker-tenant MOB where the cap-rate widening was closer to conventional office. The new loan sizes to 9.5% to 11.5% debt yield, the existing loan was struck at 7.5% to 9%, and the differential has to be filled with paydown unless trended NOI has caught up.

The math: take trailing 12 NOI net of normalized capex and TI / LC reserves, divide by today's debt-yield floor (9.5% to 11.5%), compare to existing balance plus prepay. The credit profile of the largest 3 to 5 tenants and the WALT of the rent roll often matter more than the headline occupancy in setting the final sizing.

What are the common pitfalls in an MOB refinance?

Five recurring traps:

• Hospital-system tenancy concentration. A single hospital system anchoring 60%+ of the rent roll is a strength when the system is investment-grade and a vulnerability when it is sub-investment-grade. Lenders run separate underwriting on the anchor's credit and may haircut sizing if the anchor's bond ratings have moved.
• Specialty improvements and re-tenanting cost. Medical buildouts (imaging suites, surgery centers, clinical labs) carry $200 to $500 PSF in TI cost. The re-tenanting reserve in lender sizing has to account for the specialty cost, not generic office TI.
• Off-campus weak referral patterns. An MOB that loses its on-campus or hospital-affiliation status during the loan term faces tenant fallout because physicians want patient flow from the system. The right defense is documented referral patterns and long-term lease extensions tied to the affiliation.
• Healthcare regulatory exposure (Stark, anti-kickback). Lease structures must comply with Stark Law fair-market-rent requirements when the landlord and tenant share referral relationships. Lenders flag any non-FMV lease structures in diligence.
• Property tax exemption status. Some MOB assets sit on land owned by tax-exempt healthcare systems via long-term ground leases. The ground-lease structure (fixed payments, escalators, remaining term) must be acceptable to the lender, and most lenders require at least 30 to 40 years of remaining ground-lease term inside the loan maturity.

How does the 2026 maturity wall affect MOB refis?

MOB sits in a favorable spot in the maturity wall. Most stabilized assets refinance cleanly. The weak slice is off-campus generalist MOB in markets where physician consolidation has reduced demand for standalone medical space. Per the Fed's January 2026 SLOOS readout, banks have not tightened MOB standards as aggressively as conventional office, which preserves the bank bench for the asset class.

Per the FDIC Q1 2026 Quarterly Banking Profile, community-bank MOB concentration has grown modestly as bank capacity rotated away from generalist office and into MOB. The result is that small-balance MOB has a deeper bank bid in 2026 than it did three years ago, which is the opposite trajectory from conventional office.

Conversion of weak conventional office to medical use is a real theme in the 2026 to 2027 maturity wall, with debt-fund bridge financing the conversion and life-co or CMBS take-out at stabilization. The conversion economics turn on the cost of medical buildout per square foot and the achievable rent premium versus generic office.

When should I start the MOB refinance process?

Twelve to fifteen months before maturity. The lender options is deep enough that a parallel quote process across life co, CMBS, and bank is the right default for any institutional MOB of $15M+. The early start is most valuable for off-campus and weaker-tenant assets where lease extensions or a credit-tenant pre-lease can move the asset from downside-renewal underwriting to in-place underwriting.

For conversion plays, 18 to 24 months is the right runway because the bridge financing, the medical buildout, and the take-out negotiation all run sequentially. The conversion economics depend on hitting defined leasing milestones inside the bridge term, which requires a credible operating partner and a defined tenant pipeline before the bridge funds.
