Shared Ownership properties are provided through housing associations or local authorities. You buy a share of the home and pay subsidised rent on the remainder. You only need a deposit based on your share — not the full market value — which significantly reduces the upfront cost compared to buying outright.
Over time, you can buy additional shares in your home through a process known as staircasing, either by borrowing more from your lender or making a cash payment. Most people staircase until they own the property outright. When you contact us, we will walk you through every stage from initial eligibility through to your mortgage offer.

To qualify you must typically have a household income of no more than £80,000 per year (£90,000 in London), be a first-time buyer or a homeowner who cannot currently afford to buy, and intend to live in the property as your main residence. Our advisers assess your full situation to confirm your eligibility and find the right lender for you.

No — shared ownership mortgages are not more expensive than standard mortgages. You do need to factor in that you pay rent on the share you do not own, alongside your mortgage repayments. Your full affordability is assessed before any recommendation to make sure you can comfortably cover both. Once we have your information, we calculate your exact monthly costs.
Under the Shared Ownership scheme, the minimum share you can purchase is 10% under the new model lease introduced in 2021. Older shared ownership properties may still have a minimum of 25%. We confirm the applicable minimum for any property you are considering before you proceed.
Yes — you can remortgage a shared ownership property to switch to a more competitive rate or to release equity from the share you own. The mortgage works in the same way as a standard residential mortgage, except it is secured against your share of the property rather than the full market value. Our advisers can find the right remortgage deal for your circumstances.
