The Signal:
- MOB is re-rating as a defensive core class as commodity office weakens.
- Health-system anchors give MOB leases credit and stickiness office lacks.
- Demographic demand for outpatient care underpins durable occupancy.
The clearest capital rotation in CRE right now runs from traditional office into medical office. A more than fivefold rise in annual MOB deal value over a decade, to 154B dollars in 2025, reframes the asset from niche to core. The occupancy gap tells the story: 92.3% for MOB against 80.2% for conventional office.
The Cornerstone Plaza trade is the pattern in miniature: a health-system-anchored asset, anchored by Cook Children's, changing hands within a specialist buyer pool. Outpatient migration, aging demographics, and the operational cost of relocating clinical space make MOB tenancy far stickier than commodity office.
Implications: For office investors, MOB is where defensive capital is rotating. For developers, health-system anchors and outpatient adjacency are the underwriting core. For lenders, MOB's occupancy and credit profile support terms that commodity office no longer earns.
Key Takeaways
- When medical office runs 12 points of occupancy above traditional office, the office label is doing all the work and none of the risk.
- MOB is re-rating as defensive core as commodity office weakens
- Health-system anchors give MOB leases credit and stickiness office lacks
- MOB earns lending terms commodity office no longer commands
