GCM Grosvenor’s investment supports the continued growth of the Proteus MHP platform, which currently owns and operates roughly 3,300 sites nationwide

CHICAGO and LOS ANGELES, Oct. 28, 2026 (GLOBE NEWSWIRE) -- Proteus MHP, a private real estate investment and operating firm focused on manufactured housing communities, today announced that GCM Grosvenor’s real estate practice, a leading middle market real estate platform builder and GP stakes investor, has increased its investment in the platform to ~$145 million. The two firms launched their partnership in April 2025, and currently own and operate 19 manufactured housing communities throughout the United States. The new investment will allow Proteus MHP and GCM Grosvenor to grow their portfolio to ~$400 million of assets.

Founded in 2022 by Bowen Hsu and Marcus Consunji, Proteus MHP is a vertically integrated owner-operator focused on acquiring and improving quality, attainable housing. The firm currently owns and operates 35 manufactured home communities totaling roughly 3,300 sites. Hsu and Consunji bring over 30 years of combined real estate experience and have collectively executed more than $5 billion of transactions across multiple asset classes nationwide.

The firm's operational platform integrates acquisitions, asset management, and property operations to drive long-term value and resident satisfaction. Proteus MHP targets well-located, underinvested communities where strategic capital improvements and hands-on management can potentially generate attractive, risk-adjusted returns.

Peter Braffman, Managing Director at GCM Grosvenor, said, "The growth we've seen across the platform over the past 18 months reflects the strong execution of Bowen, Marcus, and the broader Proteus MHP team. We are pleased to expand our commitment and continue supporting their disciplined approach to scaling a high-quality, attainable housing platform."

Bowen Hsu and Marcus Consunji, Co-Founders of Proteus MHP, added, "This new investment is a strong vote of confidence from GCM Grosvenor in our platform and our team.
