What Shared Ownership Actually Is

Shared ownership is a scheme where you buy a percentage stake in a home — typically 25 to 75 percent — and pay rent to a housing association for the part you don't own. You get a mortgage for your share, a lease for the property, and the right to increase your ownership stake over time through a process called staircasing. The housing association retains ownership of their share and collects rent from you monthly.

This is different from renting alone: you build equity in the portion you own, you can eventually own the whole property if you staircase to 100 percent, and you have legal rights as a leaseholder. It is also different from buying outright: your monthly costs include both a mortgage payment and rent, and you cannot sell your share to anyone — only back to the housing association or through a resale scheme they control.

Shared ownership schemes are run by housing associations, which are nonprofit organizations regulated by the government. The scheme exists because full home purchase is out of reach for many people: you need a smaller deposit (often 5 to 10 percent of your share's value rather than 15 to 20 percent of a full property price), a lower income to may have access to for the mortgage, and lower monthly payments than a full mortgage would require.

Key Takeaways

  • You buy a share of the property (usually 25 to 75 percent) with a mortgage and pay rent on the housing association's share, meaning your monthly cost is lower than a full mortgage but higher than renting alone.
  • Your deposit is typically 5 to 10 percent of your share's value, not the full property price, which makes entry cheaper than traditional home purchase.
  • You can increase your ownership stake over time through staircasing, buying additional shares from the housing association at updated property valuations.
  • Shared ownership is available only through housing associations, and each scheme has its own rules about resale, staircasing costs, and which properties you can buy into.
  • You need a mortgage lender willing to lend on a shared ownership lease, which narrows your options compared to standard mortgages.

Income and Deposit Requirements

Income limits vary by housing association and by region. Most schemes set a household income cap between £80,000 and £90,000 in London and between £60,000 and £70,000 outside London, though some associations set lower thresholds. You will need to provide recent payslips, tax returns, and proof of employment to show you meet the limit. Self-employed applicants typically need two years of accounts.

Your deposit is calculated on your share of the property, not the full purchase price. If you are buying a 50 percent share of a £200,000 property, your share is valued at £100,000, and a 10 percent deposit would be £10,000 — not £20,000 to £40,000 as it would be for the full property. Some schemes accept deposits as low as 5 percent; others require 10 percent or more. The housing association will tell you the exact percentage when you receive an offer.

You will also need to pass a mortgage lender's affordability check. Lenders will look at your income, existing debts, and the total of your mortgage payment plus the rent you will owe. If your combined monthly housing cost exceeds roughly 30 to 35 percent of your gross household income, you may not be approved. This is stricter than the affordability rules for standard mortgages in some cases because rent is treated as a fixed ongoing cost.

How the Mortgage and Rent Work Together

Your monthly housing payment has two parts. The first is your mortgage, which you pay to the lender and which builds equity in your share. The second is rent, which you pay to the housing association for their share of the property. The rent is typically set at around 2 to 3 percent of the housing association's share value per year, though this varies by scheme and location.

Example: You buy a 50 percent share of a £200,000 property. Your share costs £100,000. You put down £10,000 and borrow £90,000 on a 25-year mortgage at current rates. Your mortgage payment might be around £450 per month. The housing association's 50 percent share is valued at £100,000, so their annual rent might be £2,000 to £3,000 — roughly £170 to £250 per month. Your total monthly housing cost would be approximately £620 to £700, plus service charges and council tax.

Rent typically increases each year in line with inflation or a fixed percentage set in your lease. Service charges — for maintenance, insurance, and communal areas — are separate and also rise over time. You are responsible for all repairs to your share and for your share of building insurance. The housing association handles repairs to common areas and their share of the building.

Staircasing: Buying More of Your Home

Staircasing is the process of buying additional shares from the housing association to increase your ownership stake. You can staircase at any point after you own your initial share, and you can do it in steps — buying 10 percent more one year, another 15 percent five years later — or all at once. Each time you staircase, you buy the additional share at its current market value, not the price you paid originally.

To staircase, you will need a new mortgage valuation of the property, a new mortgage offer from your lender for the additional amount, and a new deposit (usually 5 to 10 percent of the additional share's value). The housing association will charge you a legal fee, typically £200 to £500, to process the staircase. The entire process usually takes 4 to 8 weeks from application to completion.

Staircasing is optional. You can own your share indefinitely without ever staircasing. However, if you want to eventually own the property outright, staircasing to 100 percent is the only way to do it. At 100 percent ownership, you own the freehold (or a very long lease), you no longer pay rent to the housing association, and you can sell the property on the open market to anyone.

Not all housing associations allow staircasing, and some set limits — for example, you may only be able to staircase up to 80 percent, or you may have to wait a minimum of three years before your first staircase. Check the scheme's terms before you commit.

Finding and Buying a Shared Ownership Property

Shared ownership properties are advertised by individual housing associations on their websites and through portals like Rightmove, Zoopla, and the government's Help to Buy portal (though Help to Buy schemes have largely closed; check current availability in your area). You search by location and price range, just as you would for any property for sale. When you find a property you are interested in, you contact the housing association directly — not a private estate agent.

The housing association will send you an information pack that includes the lease terms, service charge estimates, rent levels, and staircasing policy. Read this carefully. Lease length, ground rent (if any), and restrictions on pets, alterations, or subletting vary widely. Some leases have clauses that make staircasing expensive or impossible later, so understanding the lease before you commit is essential.

Once you have decided to proceed, you will need a mortgage in principle from a lender. Not all mortgage lenders offer shared ownership mortgages, so you may need to approach lenders who specialize in this product. Your solicitor will handle the legal work, including the lease review and the purchase itself. The entire process from offer to completion typically takes 8 to 12 weeks.

Costs Beyond the Mortgage and Rent

Your monthly housing cost is not just the mortgage and rent. You will also pay service charges, which cover building insurance, maintenance of common areas, grounds upkeep, and sometimes communal heating or water. Service charges are set by the housing association and typically range from £50 to £200 per month depending on the property and location. They are not fixed and usually rise each year.

You will pay council tax, the same as any homeowner or renter. You are responsible for buildings insurance on your share (the housing association insures their share and passes the cost to you as part of service charges). You may also pay a lease management fee to the housing association, typically £20 to £50 per year, for administering your lease.

When you buy, you will pay legal fees (usually £800 to £1,500), a mortgage arrangement fee (typically £500 to £2,000), a survey fee (£300 to £800), and stamp duty on your share (if your share's value exceeds the threshold — currently £250,000 in most of England). These upfront costs are in addition to your deposit.

Selling Your Share and Resale Rules

You cannot sell your share to a private buyer. Instead, you must offer it back to the housing association first. If they decline, you can sell through their resale scheme, which means the new buyer must also be a shared ownership buyer — they cannot be a private purchaser. This limits your pool of potential buyers and can make resale slower and more difficult than selling a freehold property.

When you sell, the housing association will have the property revalued. You will receive the proceeds of your share's current market value minus any outstanding mortgage, legal fees, and the housing association's resale fee (typically 1 to 2 percent of the sale price). If the property has risen in value, you keep the gain. If it has fallen, you absorb the loss.

Some housing associations restrict resale in the first few years — for example, you may not be able to sell within the first three to five years of purchase. Check the scheme's resale policy before you buy, because this affects your flexibility if your circumstances change.

Frequently Asked Questions

Can I get a mortgage for a shared ownership property if I have bad credit?

Mortgage lenders for shared ownership are often the same as those for standard mortgages, so credit requirements are similar. A poor credit history makes approval harder but not impossible. Specialist lenders exist for people with credit issues, though they typically charge higher interest rates. Contact a mortgage broker who works with shared ownership lenders to explore your options.

What happens if I cannot afford my mortgage or rent payments?

If you fall behind on your mortgage, the lender can take possession of your share. If you fall behind on rent, the housing association can take legal action to evict you. Contact your lender and the housing association immediately if you are struggling — many have hardship policies and may offer payment holidays or restructuring. Ignoring arrears will result in court action.

Can I staircase if my property has fallen in value?

Yes. You staircase at the current market value, not the original purchase price. If the property has fallen in value, the additional share will cost less than it would have if you had bought it at the original price. However, you will still need a mortgage lender willing to lend on a property worth less than you paid for it, which can be difficult.

Do I need permission from the housing association to make changes to the property?

Yes. Your lease will specify what alterations you can make without permission and which require written consent. Most schemes allow internal decoration and minor improvements but require approval for structural changes, extensions, or external alterations. Breaching this can result in legal action or loss of your right to staircase.

What is the difference between shared ownership and a shared equity mortgage?

Shared ownership involves rent on the housing association's share; shared equity involves a second mortgage on the lender's share with no rent. Shared equity is less common and typically available only through specific government schemes. Shared ownership is the standard product offered by housing associations across the country.
