Anchor Health Properties of Charlottesville, Va., has acquired two medical buildings in Havertown, with plans for upgrades to the property that it says will allow Crozer-Keystone Health Systems to expand.

An Anchor subsidiary paid $17 million Monday for the Crozer-Keystone Surgery Center at 2010 and 2050 West Chester Pike, according to records filed with the Delaware County Recorder of Deeds.

The seller was an affiliate of Kansas City, Mo.-based RREEF Property Trust, which held the property on behalf of the Iowa Public Employees' Retirement System, according to public filings.

Anchor said in a release that it plans to invest "several million dollars" over multiple years to redevelop the two Havertown buildings, which together compose 68,740 square feet of medical office space on a 2.3-acre campus. The company is partnering on the investment with Washington-based private-equity firm Carlyle Group.

"The improvements will allow Crozer and other tenancy the opportunity to expand and prosper over time and facilitate best-in-class treatment for area patients in a modernized medical setting," Anchor said.

A Crozer spokesman had no immediate details of the health system's expansion plans.

Anchor said it is the largest medical office landlord in the Philadelphia area, with more than one million square feet of medical office space managed or under development in the region. Other holdings include Penn Medicine Southern Chester County in West Grove and the Doylestown Health & Wellness Center in Warrington.

The Crozer-Keystone offices in Havertown sold in addition to another medical building in West Chester, N.Y. — which was acquired by another buyer — for a total of $34.4 million, according to a release from commercial real estate firm Holliday Fenoglio Fowler LP, which represented the seller in the deal.
