Synergy Investments has sold 100 Franklin St. in downtown Boston to Clarion Partners.

Clarion paid $48.75 million for the nine-story, 124,055-square-foot downtown office and retail property. The building, situated near Post Office Square, has been restored to incorporate modern upgrades.

Cushman & Wakefield team, led by President Robert Griffin, Vice Chairman Edward Maher and Executive Director Matt Pullen oversaw the transaction on behalf of Synergy Investments.

“100 Franklin Street has a storied history of strong tenancy, consistently attracting some of the region’s most recognized names, such as Webster Bank,” Pullen said in a statement. “The building is currently 93 percent occupied to a diverse tenant roster with below-market rents, presenting a desirable combination of durable in-place income and notable upside potential.”
