Centre Street Partners Launches Accretus With 1031 Exchange Acquisition

Centre Street Partners (CSP) has launched its real estate transaction services platform, Accretus, anchored by the acquisition of Atlanta Deferred Exchange (ADE), a leading qualified intermediary specializing in 1031 exchanges.

Founded in 2008 by Ron Raitz, ADE facilitates more than 600 exchanges annually and processes approximately $500 million in transaction volume for property owners and investors nationwide. The firm operates across all 50 states and is considered one of the largest independent qualified intermediaries in the U.S.

The acquisition marks CSP’s entry into the fragmented 1031 exchange services market, with a focus on modernizing operations through technology and data-driven infrastructure.

“Centre Street Partners is built around the conviction that highly trusted, profitable professional services providers like ADE stand to benefit disproportionately from the value created by technology in the coming decade,” said Jonathan Kerstein, managing partner at CSP and president of Accretus.

Accretus will be led by CEO Adam Friedman, who joins from BlackRock, where he most recently served as a director on the AI and analytics engineering team. The platform aims to address inefficiencies in the 1031 exchange process, which remains highly manual despite its importance in tax-sensitive real estate transactions.

“1031 exchanges sit at one of the most tax- and time-sensitive points in the real estate investment lifecycle,” Friedman said.

As part of the deal, Raitz will remain a minority shareholder and join the Accretus board alongside CSP leadership and operating partners.
