Property Overview
Capitol Square is a 45,340 SF, 100% occupied office and medical park featuring 18 suites across five buildings. The property is anchored by a high-synergy mix of medical and health-service tenants, including Franciscan Medical Group, Labcorp, and various dental, chiropractic, and wellness providers. This medical oriented base, combined with Federal Way’s lower occupancy costs relative to CBD alternatives, provides investors with stable, durable in-place cash flow.The asset offers significant strategic flexibility through its staggered lease expirations, which allow an investor to smooth rollover risk and mark rents to market over time. Uniquely, each of the five buildings is situated on its own tax parcel, creating a clear path for future value creation through phased sales, or individual building dispositions to owner-users. Positioned on 202,323 SF of land with ample parking, Capitol Square represents a stabilized suburban investment with built-in exit optionality.
