The $2.49 billion cash purchase will give McKesson about 70% ownership of Community Oncology Revitalization Enterprise Ventures, LLC (Core Ventures).
The medical center was 100% occupied at the time of the sale.
The 50,000-square-foot facility is on 3.53 acres on Stillwood Pines Boulevard, east of Resolution Drive and south of Butler Boulevard in Jacksonville.
Officials should break ground on the hospital in January and open in 2027.
Lifepoint Rehabilitation will operate the facility in partnership with Baptist Health South Florida.
