The house is paid off. The ground under it isn't.

Manufactured housing is sold as the affordable, self-reliant option: buy the factory-built home outright, skip the mortgage on land you don't want to maintain.▸ What that pitch leaves out is that the home doesn't move. Once a manufactured home is set on its pad, relocating it is expensive enough and damaging enough that almost no owner ever does — which means whoever owns the ground underneath can raise the rent on that ground with very little fear the tenant will leave. That single structural fact is now the whole business model.

An estimated 17 million residents live in manufactured housing, according to Fannie Mae's analysis of 2022 American Community Survey data.▸ A large share of them live in "land-lease" communities — commonly called mobile home parks — where the resident owns the physical structure but rents the pad site beneath it from the community's operator. As of the second quarter of 2024 there were just over 44,000 of these communities nationwide, per the same Fannie Mae report, and almost none are being added: in 2020, developers built 1,687 new pad sites and demolished 1,368, for a net gain of 319 sites in the entire country. Occupancy in existing communities sits at 94–99% depending on region and age restriction. Supply is frozen, demand is not, and the residents renting a pad can't easily shop around — which is exactly the setup an investor wants.

The U.S. Government Accountability Office found in 2023 that private investors and real estate investment trusts have been buying up manufactured housing communities at a rising pace, with purchases reaching as high as $9.4 billion in 2021 — the highest volume in the five years GAO reviewed, per Fannie Mae data cited in the report.▸ The payoff shows up directly in the rent:

Manufactured-home pad-site rent rose 6.6% nationally in the year ending Q2 2024 — more than double the 3.0% non-seasonally-adjusted inflation rate and roughly six times the estimated 1.1% national increase in apartment rents, per Fannie Mae's own market commentary.▸ It's not a one-year spike: pad-site rent grew 7.5% the year before that, meaning it has now "outpaced both multifamily rents and inflation for the second year in a row," in Fannie Mae's words. The regions vary, but none of them are slow:

Six firms now dominate enough of this market that the top Democrat on the Senate's Joint Economic Committee opened an investigation in December 2025, sending document requests to Alden Global Capital (owner of Homes of America), The BoaVida Group, Legacy Communities, Patriot Holdings, Philips International, and Sun Communities.▸ The letters cite specific cases: The BoaVida Group and Philips International reportedly raised rents more than 50% in some Maine communities since 2021, and Homes of America agreed in 2024 to repay West Virginia residents to settle claims over a rent increase residents called "unconscionable." One landlord, Patriot Holdings, advertises the strategy outright to its own investors, promising "rent increases in line with market demand" — a demand it describes as "booming."

The rent data those firms point to as "market demand" has its own legal shadow.▸ A federal antitrust class action now consolidated in the Northern District of Illinois — In re Manufactured Home Lot Rents Antitrust Litigation, No. 1:23-cv-06715 — alleges that Datacomp Appraisal Systems, the same data provider Fannie Mae cites for the rent figures above, let competing park operators trade non-public pricing and occupancy data with each other, enabling them "to increase manufactured home lot rents systematically and unlawfully." The defendants have not been found liable; one, Murex Properties, reached a preliminary settlement in March 2026, while the case continues against the rest. Nobody disputes the rent went up. What's in court is who agreed to raise it, and how.

Rent figures are Datacomp/JLT trailing 12-month averages as reported by Fannie Mae for investor-tracked all-ages and age-55+ communities; they may not reflect rents at nonprofit, cooperative, or resident-owned communities. The $9.4 billion investor-purchase figure is GAO's 2021 estimate and is not a current-year figure. Antitrust allegations described above are allegations in ongoing litigation, not adjudicated findings.
