Medical office buildings (MOBs) are among the most sought-after commercial real estate assets in 2026, and lenders have responded by creating specialized underwriting specifically for healthcare real estate. If you’re financing a MOB, applying traditional office lending criteria will lead to worse terms than your asset deserves. Here’s how MOB financing works.
Why MOB Financing Is Different from Traditional Office
Medical office buildings share a building type with traditional office but have almost nothing else in common from a lending perspective:
- Tenant stickiness: Medical tenants (doctors, specialists, medical groups, health systems) rarely relocate, their equipment, exam rooms, and patient relationships are deeply embedded in their space. Average tenancy for medical office is 8–12 years vs. 3–5 years for traditional office.
- Demand driver independence: Healthcare demand is driven by demographics (aging population), not economic cycles. Medical office demand grows regardless of remote work trends or economic downturns.
- Higher buildout costs: Medical tenants invest $100–$300+ per square foot in tenant improvements, creating extraordinary switching costs that protect occupancy.
- Health system credit: Hospital-anchored MOBs often carry investment-grade credit behind their rent rolls.

How Lenders Underwrite MOBs
Tenant Credit and Lease Structure
MOB underwriting focuses heavily on tenant quality. A hospital health system anchor (investment-grade credit) creates a fundamentally different risk profile than a roster of private practice tenants. Lenders look at:
- Weighted average lease term (WALT), longer is better; medical tenants with 7–10 year leases are highly valued
- Tenant credit quality (health system vs. independent practice)
- Lease structure (NNN, modified gross, full gross), NNN preferred
- Renewal options and probability of renewal
- Percentage of health system-affiliated vs. independent tenants
On-Campus vs. Off-Campus Premium
MOBs physically located on a hospital campus or directly adjacent command premium pricing vs. off-campus properties. On-campus MOBs benefit from referral relationships, pedestrian traffic, shared services, and an institutional affiliation that dramatically reduces vacancy risk.
Medical Specialization
MOBs heavily specialized in one medical discipline (oncology, imaging, surgery) carry concentration risk but also significant tenant stickiness, specialized medical tenants almost never relocate. Lenders generally don’t penalize specialization unless the building has a single-tenant profile with no diversification.
DSCR
Medical office DSCR requirements are typically 1.20x–1.25x, lower than traditional office because of stronger tenant quality and lease durability. This is a significant underwriting advantage over conventional office lending.
On-Campus vs. Off-Campus MOBs: Financing Differences
| Factor | On-Campus MOB | Off-Campus MOB |
|---|---|---|
| Vacancy risk | Very low (hospital affiliation) | Low (medical stickiness) |
| Max LTV | 68–72% | 63–68% |
| Rate premium vs. traditional office | 75–125 bps tighter | 50–100 bps tighter |
| Lender pool | All categories (life companies active) | Banks, CMBS, debt funds |
| DSCR requirement | 1.15x – 1.20x | 1.20x – 1.25x |
| Exit cap rate (valuation) | Tighter (lower cap rate) | Slightly higher cap rate |

Frequently Asked Questions
Are medical office buildings easier to finance than traditional office?
Yes, significantly. Medical office buildings are treated as a separate, more favorable asset class by most CRE lenders in 2026. Lower DSCR requirements (1.20x vs. 1.30x+), higher LTV allowances (65–70% vs. 55–65%), lower rates, and broader lender appetite distinguish MOB financing from traditional office financing. The demographic tailwinds driving healthcare demand and the extraordinary tenant stickiness of medical tenants make MOBs one of the most lender-friendly commercial property types.
What documentation do medical office lenders require?
Medical office lenders require standard commercial documentation plus healthcare-specific items: current signed leases with healthcare tenant information, T-12 operating statement, rent roll showing specialties of tenant practices, hospital affiliation status (if any), and sometimes tenant revenue or patient volume data (for newer or smaller practices) to assess tenancy durability. On-campus MOBs may also require hospital ground lease or parking agreements.
