What Your OM Needs to Address
Health System Affiliation
Properties with Banner, HonorHealth, or Dignity Health tenants trade at 50-75 basis point cap rate compression
Data to Include
Master lease terms, health system guarantees, referral network dependencies, expansion rights
Specialized Infrastructure
Medical gas systems, imaging shielding, and enhanced HVAC drive re-tenanting costs to $75-150/SF
Data to Include
Recent TI investments, infrastructure age, compliance certificates, future capital needs
Regulatory and Licensing
Arizona Department of Health Services requirements affect ambulatory surgery center operations
Data to Include
Current licenses, certificate of need status, compliance history, pending regulatory changes
Water and Utilities
Phoenix water availability concerns affect long-term development, existing properties less impacted
Data to Include
Water rights documentation, utility capacity, conservation measures, long-term supply agreements
Parking Ratios
Medical office requires 4.5-6 spaces per 1,000 SF versus 3.5 for general office
Data to Include
Current parking count, city requirements, shared parking agreements, valet options
Tenant Credit Analysis
Independent physicians face reimbursement pressure while health systems expand market share
Data to Include
Payor mix, accounts receivable aging, health system employment trends, practice acquisition risk
Investment Outlook
Short Term
Cap rate expansion likely as interest rates remain elevated. Health system-anchored properties maintain pricing power. Independent physician practices face margin pressure from reimbursement cuts.
Medium Term
Outpatient migration continues favoring ambulatory surgery centers and specialty clinics. Older medical office buildings need significant capital or conversion to alternative uses. Banner and HonorHealth expansion drives selective demand.
Long Term
Phoenix's aging population supports medical office fundamentals through 2035. Technology may reduce space needs per provider but population growth offsets. Water constraints limit new suburban development, benefiting existing properties.
Buyer Profile
Healthcare REITs seeking scale, local physician groups buying practice space, private equity backing ambulatory surgery center development. Family offices attracted to health system triple-net lease properties.
