Why Medical Office Outperforms General Commercial Office
While traditional corporate office buildings have faced headwinds from hybrid and remote-work trends, Medical Office Buildings (MOBs) have demonstrated sustained operational strength. Healthcare delivery requires in-person patient examinations, specialized clinical diagnostics, surgical procedures, and physical therapy that cannot be replicated remotely.
Furthermore, physicians and hospital systems invest tens of thousands of dollars per exam room in specialized plumbing, radiation shielding, biohazard waste infrastructure, and computerized diagnostic machinery. This massive capital investment makes healthcare tenants exceptionally sticky, driving lease renewal rates exceeding 85% to 90%.
On-Campus vs. Off-Campus Outpatient Assets
Lenders evaluate the strategic location of the medical asset relative to regional healthcare systems:
On-Campus Medical Buildings
Located directly on or adjacent to a major acute-care hospital campus. Often subject to ground leases with the hospital system, requiring specialized leasehold mortgage underwriting.
High prestige and direct patient referral integration
Requires review of hospital ground lease restrictions and specialty exclusivity clauses
Off-Campus Ambulatory & Retail Infill MOBs
Positioned in accessible suburban commercial corridors closer to residential populations. Healthcare networks actively expand off-campus outpatient facilities to lower costs and capture market share.
Fee simple ownership with clean mortgage encumbrance
Requires high parking ratios (5.0+ spaces per 1,000 SF) to handle patient volume turnover
Because clinical buildouts are capital intensive, medical office leases feature larger upfront Tenant Improvement allowances ($80–$150+/SF) offset by 10 to 15-year initial terms. Lenders structure funded leasing commissions and TI reserves into loan facilities, protecting borrowers as practice groups expand.
Frequently Answered Questions
Common Questions About Medical Office Building (MOB) & Healthcare Real Estate Financing
Direct, transparent answers regarding underwriting standards, documentation, and process.
Medical vs General
Why are medical office buildings underwritten more favorably than general corporate office?
Direct Answer
Medical office buildings require physical in-person visits and feature heavy tenant investment in specialized clinical equipment, resulting in lease renewal rates exceeding 85%–90%.
This insulation from work-from-home trends allows lenders to offer higher advance rates and lower interest rate spreads.
Parking Standards
What parking ratio do commercial lenders require for medical office properties?
Direct Answer
Lenders typically require 5.0 to 6.0+ parking spaces per 1,000 square feet for medical office, compared to only 3.0 to 4.0 spaces for standard general office buildings.
Higher parking ratios are essential to accommodate rapid patient turnover, nursing staff, and medical transport vehicles.
