With shared ownership you only need a deposit on the share you are buying, not the full property price. The minimum is usually five per cent of your share. The more you put down, the better the mortgage rates available to you. Here is a breakdown of what different deposit levels mean for your shared ownership mortgage:
Many buyers turn to online calculators for an initial affordability figure, but these tools are often inaccurate for shared ownership because they do not account for the rent element or the specific criteria of specialist lenders. Our advisers will assess your actual borrowing capacity based on your income, outgoings, credit profile, and the criteria of lenders who offer shared ownership mortgages. This gives you a real, reliable figure rather than a rough estimate.
Important: The monthly repayment figure you'll pay depends on three things: how much you borrow, the interest rate offered, and the length of your mortgage term. With rates higher now than in recent years, it's essential to get an accurate repayment figure before you start viewing properties — so you can set a realistic budget.
How Does Mortgage Term Affect Monthly Payments?
The average mortgage term is 25 years, but many lenders now extend this to 35 or even 40 years, provided you'll still be below retirement age at the end of the term. A longer term means lower monthly payments — but you'll pay more in total interest over time. Your adviser will help you find the right balance.
Buying your share comes with a range of one-off costs that many people overlook. Before you start viewing properties, make sure you have planned for these upfront expenses:

Our advisers always run through a full budget planner with you before any application is submitted, including the combined cost of your mortgage payment and rent on the unsold share. We make sure the total monthly commitment is genuinely affordable before anything is submitted.
Shared ownership allows you to buy a share of a home — typically between ten and seventy-five per cent — and pay rent on the share you do not own, which is retained by a housing association. You take out a mortgage on your share, making the monthly cost lower than buying outright. Over time you can purchase additional shares through staircasing until you own the property outright.
To be eligible your household income must be £80,000 or less per year (£90,000 or less in London). You must be a first-time buyer or a former homeowner who cannot currently afford to buy. Priority is often given to existing social tenants, armed forces personnel and key workers.
You are a leaseholder, meaning you own the right to live in the property for the duration of the lease (typically 99 to 125 years), while the freehold belongs to the housing association. You have full rights to use and decorate the property and can staircase to one hundred per cent ownership over time.
The rent on the share you do not own is typically set at around two to three per cent of the value of that share per year. On a £300,000 property where you own fifty per cent, you might pay around £250 per month in rent. The rent can increase annually, usually in line with RPI plus a small percentage.
With shared ownership you only need a deposit and mortgage on your share, not the full property value. However, you also pay rent on the remaining share plus service charges, so the true monthly cost is worth calculating carefully against a standard purchase before you proceed.
