Everything you need to know about shared ownership mortgages uk in the UK.
Shared ownership is a government-backed scheme that helps people who cannot afford to buy a home outright get onto the property ladder. You buy a share of a property (between 25% and 75%) and pay rent on the remaining share to a housing association. You only need a mortgage and deposit for the share you are purchasing, making it significantly more affordable than buying outright.
For example, on a £250,000 property, if you buy a 40% share (£100,000), you need a mortgage and deposit based on £100,000, not the full property price. A 5% deposit would be just £5,000. You then pay subsidised rent on the remaining 60% share owned by the housing association, typically set at 2.75% of the housing association's share per year.
Shared ownership is available on both new-build and resale properties. New-build shared ownership homes are sold through housing associations, while resale shared ownership properties are marketed through the housing association that owns the retained share.
To qualify for shared ownership in England, you must meet these criteria:
Military personnel have priority access to shared ownership schemes, and the eligibility criteria may be more relaxed for armed forces personnel and their families.
Not all mortgage lenders offer shared ownership products, so the pool of available lenders is smaller than for standard purchases. However, many major lenders including Halifax, Nationwide, Leeds Building Society, and several specialist lenders do offer shared ownership mortgages.
Rates on shared ownership mortgages are generally comparable to standard residential mortgage rates, though the choice of products may be more limited. You can typically choose from fixed rate, tracker, and variable rate options.
A key difference is that the lender assesses affordability based on both your mortgage payments and the rent on the housing association's share. This combined cost must be affordable within the lender's criteria. Some lenders also factor in potential rent increases when stress-testing affordability.
💡 Because fewer lenders offer shared ownership mortgages, using a specialist mortgage broker is particularly valuable. They know which lenders accept shared ownership applications and can find the most competitive rates available.
Staircasing is the process of buying additional shares in your property over time, with the goal of eventually owning it outright. Under the current model, you can staircase in increments of 5% or more (reduced from the previous 10% minimum) at any time after your initial purchase.
When you staircase, the additional share is purchased at the property's current market value, not the original purchase price. This means if the property has increased in value, the additional shares cost more — but it also means your existing share has benefited from the same growth.
The process involves getting an independent valuation of the property, agreeing the purchase price with the housing association, arranging funding (usually through a remortgage or savings), and completing the legal transfer. Staircasing costs typically include a valuation fee (£200–£500) and legal fees (£500–£1,500).
Once you own 100% of the property (known as final staircasing), you no longer pay rent to the housing association, and the property becomes yours outright. At this point, you can sell it on the open market like any other property.
Shared ownership comes with several ongoing costs beyond your mortgage payment:
⚠️ Before committing to shared ownership, ensure you can afford the combined cost of the mortgage, rent, service charges, and maintenance. Use a budget calculator that includes all these costs, not just the mortgage payment. Also factor in potential rent increases over the coming years.
If you want to sell your shared ownership home, the housing association usually has a nomination period (typically 8–12 weeks) during which they can find another eligible shared ownership buyer. If they do not find a buyer within this period, you can sell on the open market.
If you own less than 100%, you sell your share plus any equity growth. If you have staircased to 100%, you sell the entire property on the open market. The housing association has no further involvement once you own the property outright.
Selling a shared ownership property can sometimes take longer than selling a standard property, as the pool of buyers is limited to those who meet the eligibility criteria during the nomination period.
