Understanding Co-Ownership

What is Co-Ownership?

We help you buy the home that’s right for you by sharing the cost. You buy the part you can afford, and we buy the rest.

Buying a home in Northern Ireland can feel challenging, especially if the full purchase price or deposit is out of reach. Co-Ownership offers an affordable home ownership solution through shared ownership, helping you move into your own home sooner, without needing to buy it all at once.

With Co-Ownership, you purchase the share of the property you can afford and we purchase the remainder. Each month you pay a mortgage on your share and a low rent on ours. This reduces the upfront cost of buying and keeps monthly payments manageable.

Over time, as your circumstances change, you can increase your share, including up to full ownership if that’s your goal. But there’s no pressure to do this, and no fixed timeline attached. You buy more at a pace that works for you.

Who we are

Co-Ownership is Northern Ireland’s only shared ownership provider, regulated and part-funded by the Department for Communities. Since 1978, we’ve helped more than 35,000 households across Northern Ireland become homeowners.

As a not-for-profit organisation, our focus is simple: making home ownership more achievable. We reinvest money we receive to help more local people buy their own home.

Our products

Co‑Ownership offers two products, each designed for a different stage of life and a different way of financing your move. 

They work differently, but together they make home ownership possible for many people, and you can choose the option that best fits you based on your age, finances, and the kind of support you need.

For a full comparison see Our products.

Whether you’re buying your first home, returning to the market or planning for later life, Co-Ownership can help you take the next step.
