Positioned in the heart of Mesa’s thriving medical corridor, 5555 E Baseline Rd presents a rare opportunity to acquire a fully leased, stand-alone medical office asset with long-term income stability. Built in 2019, this ±8,876 SF facility is 100% leased to a single tenant under a five-year NNN lease that commenced April 2024 and runs through March 2029, with three five-year renewal options. The lease generates $310,660 in annual income ($35/SF) with 3% annual escalations, delivering a solid 6.5% cap rate and minimal landlord obligations. The property features a highly functional medical layout including 20 exam rooms, two nurses stations, two break rooms, six restrooms, and dedicated IT and storage areas. With a generous parking ratio of 6.31/1,000 (56 surface spaces), the site supports high patient throughput and operational efficiency. Located on a 2.02-acre parcel, the building benefits from proximity to major healthcare institutions such as Banner Gateway, Banner Heart Hospital, and HonorHealth Mountain Vista, as well as retail anchors like Superstition Springs Center and Mesa Pavilions. Mesa’s East Valley submarket continues to demonstrate resilience, with a 10.9% vacancy rate and competitive rental averages. The surrounding area boasts strong demographics, including a projected 5-mile population of 358,945 by 2029 and a median household income of $73,715. This investment offers a compelling blend of location, tenant stability, and long-term growth potential in one of Arizona’s most dynamic healthcare hubs.
