Atlanta-based investment outfit Domain Capital Group has officially taken over Simpson Property Group, the Denver-headquartered developer and multifamily manager with communities spread across the country. The deal upgrades a long-standing advisory relationship into full ownership of Simpson’s vertically integrated development, construction, and property-management platform. Company leaders say the everyday playbook stays the same, with Simpson’s executive team remaining in place while the combined operation chases growth.
The sale was first reported by the Atlanta Business Chronicle on March 11, 2026, following a company announcement that laid out the closing details and a roadmap to scale Simpson’s institutional offerings.
Deal details and leadership
Domain said the acquisition closed on March 9 and that it purchased Simpson from The State of Michigan Retirement Systems, according to Domain Capital Group. “We are incredibly excited to formalize what has already been a deeply integrated and successful partnership,” CEO Patrick Leardo said. The firm added that the transaction is designed to institutionalize and scale Simpson’s multifamily platform while keeping disruption to day-to-day operations to a minimum.
Simpson’s footprint and Atlanta ties
Simpson Property Group is based in Denver and runs development, construction and property-management businesses in multiple U.S. markets. The company oversees a portfolio of apartment communities and includes The Residence Buckhead among its Atlanta properties.

Why the move matters
The acquisition shifts a decades-long advisory relationship into outright ownership at a moment when private-equity players are scooping up operating platforms to build out fee-bearing institutional products. Industry reporting notes that Domain manages roughly $8.3 billion in assets and plans to roll out new commingled funds and separately managed accounts anchored by Simpson’s platform, as outlined in company materials and trade coverage. Observers see the deal as part of a broader pattern of pulling operating businesses under investment managers in order to widen institutional distribution.
What to watch
In Atlanta, the move adds another heavyweight owner to the local real-estate scene and could route more institutional capital into development and management activity tied to Simpson’s platform. Simpson CEO Frank Rooney Jr. said, “We are thrilled to be working even more closely with Domain as we enter this next chapter of growth,” and both companies emphasized that they intend to prioritize continuity while looking for ways to expand options for institutional investors.
