Key market drivers

Medical office remains a resilient growth engine


Demographic Tailwinds

The U.S. population aged 65+ is projected to reach 70 million by 2030, dramatically increasing the need for outpatient services, chronic care management and accessible medical facilities. This generational shift supports long-term fundamentals for MOBs.

Outpatient Care Expansion

Healthcare systems are rapidly transitioning from inpatient to outpatient care models to reduce costs and improve patient access. This shift is generating strong demand for well-located, purpose-build MOBs with major health system affiliations.

Stable, Long-Term Tenancy

MOBs maintain occupancy rates above 93% in top markets, driven by essential services, specialized tenant improvements and long-term leases that promote stability and predictable cash flows. Medical practices are more reluctant to move locations to maintain continuity with their patient bases resulting in ‘sticky’ tenancy and more predictable occupancy.

Investment strategy

Our approach

RMR’s medical office platform is built on expertise, tenant alignment and disciplined execution – ensuring long-term performance in a sector where reliability and clinical functionality are paramount. Each asset is strategically located to provide accessibility and convenience for patients and providers alike.

Our team deeply understands clinical operations, facility compliance and the specialized needs of medical tenants. We develop tailored property management strategies for every asset to optimize operational performance to what best supports patients, staff and care delivery models.

We partner with leading regional and national healthcare providers and purposefully foster these relationships to enhance performance, enable scaling of services and drive proprietary growth opportunities.
