Shared ownership is one of the main routes onto the property ladder for people who cannot afford to buy a home outright. The idea is simple: you buy a share of a property and pay rent on the remainder. However, the details matter, and it is worth knowing precisely what you are taking on before you commit.
What is shared ownership?
Under the scheme, you buy a share of a home, usually between 25% and 75% in England, although some new-build homes allow a first share as low as 10%. Initially, you take out a mortgage (and pay a deposit) on that share only, which is why the sums needed are smaller than for an outright purchase. The remaining share is owned by a landlord, typically a housing association, and you pay rent on that part.
Crucially, shared ownership is now considered a long leasehold in the eyes of the law. Essentially, you are buying a long lease of your share, rather than the freehold, and the lease sets out your rights and obligations. This entails reading the agreement carefully and makes taking legal advice especially important.
Who is the scheme aimed at?
The scheme is aimed at people who cannot afford a home that meets their needs on the open market. In England there is a household income cap – currently £80,000 a year, or £90,000 in London – and it is generally open to first-time buyers and to those who do not already own another property.
For those considering a buy-to-let option, if you, as a shared owner, receive permission from your housing association to sublet your home, you are legally classified as a private landlord. This means issuing rolling periodic tenancies and a prohibition of "Section 21" no-fault evictions against your tenants.
What will it cost and who pays for repairs?
Expect three monthly outgoings. First is your mortgage payment on the share you have bought. The second is the rent on the landlord's share (for new-build homes this is often set at 2.75% of the value of the landlord's share each year, rising annually under a formula in the lease). Third, you will face a service charge towards the building and communal areas and, for some older properties, ground rent. Taken together, the monthly outgoings can be closer to the cost of ownership than people might expect.
Repairs are one of the most misunderstood features. As a shared owner, you are generally responsible for the upkeep of your home and for the full service charge, even though you own only a share. Newer-build homes come with some protection in that, for the first ten years, while you own less than 100%, the landlord is usually only responsible for certain essential repairs to the structure and exterior, and you can claim up to £500 a year towards essential repairs to things like heating, water and electrics. Beyond these allowances (and on older leases), the costs largely fall to you.
Can I increase my share later?
Yes! This is called "staircasing". You can buy further shares over time, and as your share grows, the rent you pay on the landlord's share falls. In many cases, you can staircase all the way to 100% and own the property outright. Newer leases also let you buy an extra 1% each year for the first 15 years, with no administration fee – a gentler way to build up your stake than the larger blocks required in the past.
In summary, as a prospective shared owner, you face:
- Lower Initial Costs: You buy a share (10% to 75%) using a smaller deposit based only on that share's value, making it cheaper upfront than a standard purchase.
- Three Monthly Payments: You must budget for your mortgage payment, a subsidised rent on the landlord's share, and a building service charge.
- Income Eligibility Limits: Your household income must be £80,000 or less (£90,000 or less in London) to qualify.
- Full Repair Obligations: You are responsible for 100% of the property's maintenance costs, though newer properties offer 10 years with structural cover and a £500 annual repair allowance.
- Staircasing to 100%: You can gradually buy more shares over time to reduce your rent, including an option on newer leases to buy 1% extra each year.
- Stronger Legal Protections: Recent laws protect you from fast-track rental evictions if you fall behind on rent, treating you securely as a homeowner rather than a standard tenant.
- Selling Restrictions: When selling, the housing association gets a first-refusal period to find a buyer from their waiting list before you can market it openly.
Before you commit
When you come to sell, you may sell your share at its market value, although the lease usually gives the landlord a period to find a buyer before you can market it more widely. This means that a sale can take longer than a standard one. Wales also has its own affordable home ownership arrangements, which differ in their rules and eligibility from the English scheme described here. Anyone buying in Wales should check the current Welsh Government guidance rather than assume the English figures apply.
Shared ownership can open the door to a home that would otherwise be out of reach, and staircasing offers a real path towards full ownership. However, it is a long-term leasehold commitment with ongoing rent, service charges and repair obligations. Before reserving, read the key information document and the lease, add up the true monthly cost, and take independent legal advice so that you know exactly what you are committing to.
