Jennifer Stein Real Estate, Inc., in conjunction with Zeustra Healthcare Real Estate Advisors – Out-of-State Cooperating Broker, is pleased to present the exclusive opportunity to acquire 12555 W National Ave in New Berlin, Wisconsin—a 16,808 square foot, fully leased outpatient medical facility strategically located within the Milwaukee Metropolitan Statistical Area (MSA). Offered at $4,500,000, the asset delivers a strong in-place net operating income of $343,875.88, representing a 7.64% capitalization rate and providing investors with durable, immediate cash flow. The property is 100% leased to a complementary mix of healthcare providers, anchored by Aspen Orthopedic Specialists, which occupies approximately 50% of the building. Aspen is a long-term tenant that has recently exercised its 5-year renewal option, demonstrating continued commitment to the location. The practice operates a comprehensive outpatient platform, including on-site MRI, digital X-ray, and physical therapy services, reinforcing the mission-critical nature of the facility and representing significant tenant investment in specialized buildout and equipment. Aspen Orthopedic Specialists maintains one additional 5-year renewal option, and its current rental rate remains below prevailing market levels, offering investors embedded upside potential. The remaining tenancy includes West Allis Primary Care Physicians and Internist LTD, both of which have recently executed 5-year renewal options, further solidifying the stability of the rent roll. All leases are structured on a triple net basis with 2% annual rent escalations, providing investors with passive ownership and consistent income growth while minimizing landlord responsibilities. 12555 W National Ave is strategically positioned within the affluent and growing Waukesha County submarket, one of the most desirable suburban healthcare corridors in the Milwaukee MSA. The property benefits from proximity to major regional healthcare systems including Froedtert Health, Advocate Aurora Health, and Ascension Wisconsin, as well as nearby facilities such as Froedtert Moorland Reserve Health Center, ProHealth Care’s Waukesha Memorial Hospital, and Ascension SE Wisconsin Hospital – Elmbrook Campus. This concentration of healthcare infrastructure drives sustained patient demand and supports long-term tenant retention. The asset also offers excellent accessibility via West National Avenue and nearby Interstate 94, Interstate 43, and Interstate 41, providing convenient access throughout the Milwaukee metro area. The surrounding corridor features a strong mix of residential density, retail amenities, and commercial development, enhancing patient convenience and visibility for medical tenants. The combination of 100% occupancy, recent lease renewals across the entire tenant roster, mission-critical orthopedic with MRI & X-Ray, triple net lease structure with contractual rent growth, and below-market rental rates positions 12555 W National Ave as a highly attractive, stabilized medical office investment. The offering provides investors with secure in-place income, minimal management responsibility, and meaningful long-term upside within a proven and supply-constrained healthcare market.
