Direct Answer
Sun Communities (SUI) is a REIT owning manufactured housing (MH) communities, RV resorts, and marinas. Manufactured housing generates extremely sticky site-lease income because residents own their homes but rent the land -- moving is expensive so residents rarely leave. Affordable housing demand and constrained new supply support MH fundamentals. The marina segment adds a waterfront asset class with similar supply scarcity.

What Does Sun Communities Do?
Sun Communities owns and leases sites in manufactured housing communities (residents own the home, lease the land) and RV resorts. The site-lease model generates uniquely stable cash flows because moving a manufactured home is prohibitively expensive, creating very high occupancy and retention. The marina segment (Safe Harbor) adds waterfront assets with constrained supply. Affordable housing demand supports MH pricing power.
Frequently Asked Questions
What does Sun Communities do and how does it make money?
Sun Communities is a REIT that owns and operates manufactured housing (MH) communities, RV resorts, and marinas. In manufactured housing communities, residents own their homes but lease the land (site) from Sun. This site-lease model generates highly stable, recurring rental income with very low turnover -- moving a manufactured home is expensive and disruptive, so residents rarely leave once established. RV resorts generate revenue from seasonal and annual site leases to RV owners, plus transient nightly stays. Marinas generate revenue from boat slip leases, dry storage, fuel, and boat services. Sun Communities earns the majority of its revenue from site leases and slip leases, with supplemental revenue from home sales (selling new manufactured homes to residents), utilities, and ancillary services.
Why does manufactured housing have high occupancy and low turnover?
Manufactured housing communities have structurally high occupancy and very low tenant turnover for a fundamental reason: the resident owns the home but not the land. Moving a manufactured home requires physically transporting it, which costs thousands of dollars and requires a destination with an available site in the same community or another one. Most residents never move their homes; they stay and continue paying site rent indefinitely. This creates extremely sticky, long-duration cash flows that behave more like an annuity than typical apartment rents. Occupancy in well-run manufactured housing communities typically runs above 95%, and tenant retention rates are far higher than conventional apartments. The supply of manufactured housing communities is also constrained -- zoning regulations and community opposition to mobile home parks restrict new development in most markets.
What is the affordable housing tailwind for manufactured housing REITs?
Manufactured housing is the largest source of unsubsidized affordable housing in the United States. Factory-built homes cost substantially less per square foot than site-built homes, making them an accessible entry point to homeownership for working-class and fixed-income households, including retirees. As the gap between manufactured housing site-lease costs and conventional apartment rents has widened (particularly in Sun Belt markets where Sun Communities is concentrated), manufactured housing has become more attractive to budget-conscious renters and first-time homeowners. Additionally, manufactured housing has improved in quality over the decades and is no longer primarily associated with lower-income markets. The affordable housing shortage creates sustained demand for Sun Communities' product.
What is Sun Communities' marina strategy?
Sun Communities expanded significantly into marina ownership through acquisitions, including the acquisition of Safe Harbor Marinas, one of the largest marina operators in the US. Marinas generate revenue from boat slip leases (similar to site leases in manufactured housing), dry storage, fuel sales, boat servicing, and concessions. Marinas have similar economic characteristics to manufactured housing: slip leases are sticky (boat owners rarely move their boats once established at a convenient marina), supply is constrained (permitting new marinas is extremely difficult due to environmental regulations and waterfront availability), and demand is supported by the large installed base of boat owners in the US. However, marinas are more cyclical than manufactured housing, as boat ownership is a discretionary luxury expense.
What are the main risks for Sun Communities?
Key risks include interest rate sensitivity (REITs use debt financing and their equity valuations are sensitive to interest rates; rising rates increase borrowing costs and can compress valuation multiples), weather and natural disaster exposure (many Sun Communities' properties are in Florida, the Southeast, and coastal areas; hurricanes and flooding can damage properties and disrupt operations), home sales execution (Sun earns revenue from selling manufactured homes on its sites; weakness in that business reduces earnings), RV market cyclicality (RV resort demand tracks discretionary consumer spending and RV purchase cycles), marina integration challenges (the Safe Harbor acquisition requires successful integration), and regulatory risk (any political action to regulate site rent increases for manufactured housing communities would affect earnings).
