A community land trust separates ownership of land from ownership of what is built on it. A nonprofit trust holds the land permanently, while residents own or rent the homes on top of it, which removes land speculation from the equation and keeps the resulting housing significantly more affordable than the surrounding market.
Because the trust retains the land long term, it can place lasting conditions on any future resale, typically limiting how much a home's price can rise regardless of what is happening in the broader housing market nearby. This keeps the home affordable not just for the first buyer but for whoever buys it next.
The model trades some individual upside, a homeowner in a trust will not benefit from runaway price growth, for durable, community-wide stability, which is precisely the trade-off that appeals to residents more interested in a secure, affordable home than in treating housing as an investment vehicle.
