SUI

Sun Communities, Inc

A real estate investment trust that owns and runs manufactured-housing communities, RV resorts under the Sun Outdoors brand, and holiday parks in the UK, renting out sites for homes and vacation stays. It began in 1975 as Sundance Enterprises, founded by a Michigan doctor named Milton Shiffman who had been investing in real estate on the side; his son Gary joined him, and the business was incorporated as Sun Communities in 1985. In 2025 it sold its Safe Harbor marina business to refocus on its core communities.
