There’s money to be made in medical real estate these days, and Chester County has recently become a hot spot for investors to put their cash.

With its $18.5 million purchase of the 73,326-square-foot Merion Building in King of Prussia from O’Neill Properties still fresh in the books, California-based American Healthcare Investors just poured more money into the acquisition of the Paoli Medical Plaza through an affiliate.

The three-building, multi-tenant Paoli complex totals 99,059 square feet right across from the Paoli Hospital, 90 percent of which is occupied.

“There is so much capital flowing into medical real estate,” CBRE’s Steve Marzullo said in a Philadelphia Business Journal report. “It’s a low-risk area, so investors who aren’t looking for very high returns but looking for some safety with their investments are buying these types of properties.”

The purchase price was not disclosed.
