Medical office buildings hold up differently through economic cycles than standard office space, largely because healthcare demand doesn't shrink the way discretionary business activity does, and because tenant improvements built for medical use, plumbing for exam rooms, reinforced flooring for imaging equipment, are expensive enough that tenants rarely relocate on a whim. Washington investors weighing the asset class should understand what makes it different before comparing cap rates against traditional office property.
Why Medical Tenants Stay Longer Than Office Tenants
A standard office tenant can often move with minimal disruption, taking desks and computers to a new suite. A medical practice that has built out exam rooms, sterilization areas, and specialized equipment installations faces a far more expensive and disruptive relocation, which translates into longer average lease terms and lower turnover than comparable general office space. That tenant stickiness is a large part of why medical office has traded at a premium to standard office in recent years.
On-Campus Versus Off-Campus Medical Office
Buildings physically attached to or immediately adjacent to a hospital campus, on-campus medical office, generally command the tightest cap rates, reflecting referral traffic and health system affiliation. Off-campus medical office, standalone buildings leased to independent practice groups or health system satellite clinics, trades at a discount to on-campus product but still benefits from the same tenant-stickiness dynamic, and Washington's growth in outpatient and urgent-care formats has expanded demand for well-located off-campus space specifically.
Where Medical Office Demand Concentrates in Washington
Seattle and Bellevue host the state's largest health system campuses and the deepest on-campus medical office inventory. Spokane functions as the medical hub for eastern Washington and much of the Inland Northwest, supporting significant off-campus medical office demand tied to regional referral patterns. Growing suburban areas around Tacoma, Everett, and Vancouver have seen new outpatient and urgent-care development follow population growth into those submarkets rather than staying concentrated at existing hospital campuses.
Specialty Build-Out Cuts Both Ways for an Owner
The same specialized improvements that make medical tenants stick around also narrow the pool of replacement tenants if a practice does eventually leave or downsize. A building built out for imaging or surgical use has real value to another provider in that specialty, but converting it to general office or a different medical use can require significant additional investment, and an owner should factor that re-tenanting cost into their return expectations rather than assuming a departing tenant's space re-leases as easily as a standard office suite would.
Parking ratio is another detail that trips up buyers coming from standard office. Medical uses generally require more parking per square foot than general office, since patients arrive throughout the day rather than employees arriving once each morning, and a building with an office-standard parking ratio can struggle to attract or retain medical tenants regardless of how well the interior space is built out.
Health System Affiliation Versus Independent Practice Risk
A lease backed by a large health system's corporate credit behaves very differently from a lease with a small independent practice group, even when both occupy similar space at a similar rent. Health system tenants generally offer stronger credit and more predictable renewal behavior tied to broader strategic real estate planning, while independent practices can be more exposed to changes in reimbursement rates, partner turnover, or a decision to sell the practice to a larger group, any of which can affect lease renewal decisions in ways a corporate tenant's lease typically wouldn't face.
Medical Office as 1031 Exchange Replacement Property
The combination of long lease terms and durable demand makes medical office attractive to exchange investors prioritizing income stability over maximum yield, though the asset class's premium pricing means going-in cap rates typically run lower than standard office or industrial alternatives. Underwriting a medical office candidate for identification should include confirming which specific medical uses the building's improvements support, since a building configured for one specialty may not suit a replacement tenant if the current lease doesn't renew.
Common Questions
Why do medical office tenants typically stay longer than standard office tenants?
Because medical build-outs, exam room plumbing, reinforced flooring for imaging equipment, and similar improvements are expensive and disruptive to replicate elsewhere, which discourages relocation compared with a standard office tenant that can move desks and computers with minimal disruption.
What is the difference between on-campus and off-campus medical office?
On-campus medical office is physically attached to or adjacent to a hospital campus and generally commands the tightest cap rates. Off-campus medical office is a standalone building leased to independent or satellite practices, trading at a discount but still benefiting from tenant stickiness.
Which Washington city functions as the medical hub for eastern Washington?
Spokane, which supports significant off-campus medical office demand tied to referral patterns across the Inland Northwest region it serves.
Does medical office property trade at a premium to standard office?
Generally yes, reflecting the sector's longer lease terms and lower tenant turnover, which typically results in lower going-in cap rates than comparable standard office space.
Can medical office buildings be used as 1031 exchange replacement property?
Yes, as real property held for investment or business use. The asset class appeals to exchange investors prioritizing income stability, though its premium pricing means yields typically run lower than office or industrial alternatives.
