When talking about share of ownership, a housing model where you own a percentage of a property and rent the rest. Also known as shared ownership, a scheme that lets buyers purchase a slice—often between 25% and 75%—while paying rent on the remaining share, it gives people a foothold on the property ladder without needing a full mortgage. A related idea is co‑ownership, where two or more parties jointly own the whole property and split costs and responsibilities. Finally, staircasing, the process of buying additional shares over time to increase your ownership stake ties the whole picture together. In short, share of ownership encompasses part‑buy part‑rent, requires staircasing to grow equity, and influences housing affordability for many first‑time buyers.
Imagine you find a two‑bedroom flat priced at £200,000. Under a share of ownership plan, you might put down a 30% deposit (£60,000) and take a mortgage for that share. The remaining 70% is owned by a housing association, and you pay rent on that portion—usually lower than market rent because it’s tied to the part you don’t own. This structure lets you sidestep the massive deposit that a full purchase would demand. Over the years, you can use staircasing to buy extra percentages when your finances improve, eventually owning 100% of the home. The key benefit is that you’re building equity while still paying a manageable rent, which often feels less risky than a huge mortgage.
Co‑ownership adds another layer. Instead of a housing association holding the larger share, you partner with a friend, family member, or even a trusted investor. Both parties contribute to the down payment and share the mortgage, maintenance costs, and any appreciation when the property is sold. This model is popular among couples who aren’t married, siblings pooling resources, or groups of friends wanting a vacation home. The agreement outlines who owns what share, how decisions are made, and what happens if one party wants out. It's a flexible alternative for people who can’t qualify for a traditional loan on their own but still want true ownership rather than just renting.
When you’re ready to increase your share, staircasing comes into play. Most schemes let you buy additional percentages in increments of 10% or 25% whenever you can afford it, often with a discounted rate compared to the open market. The process typically involves a new valuation, a separate mortgage for the added share, and an updated rent figure. By staircasing regularly, you can reduce the rent you owe and eventually eliminate it entirely. This gradual path to full ownership is why many buyers consider share of ownership a realistic stepping stone toward owning a home outright.
