Shared ownership can reduce the upfront barrier to buying a home, but it is not the same as owning a smaller property outright. You buy a percentage of a home, usually with a mortgage and deposit, while a housing provider owns the rest. You then pay rent on the portion you do not own, alongside other housing costs.
This guide focuses on the shared ownership scheme in England, where the current rules are set. The arrangement can suit buyers who cannot afford the deposit and mortgage for a suitable open-market home, but the long-term costs and lease restrictions need careful attention.
How Part Buy Part Rent Works
Shared ownership homes are sold by housing associations, councils and other approved providers. You purchase an initial share and become a leaseholder. Some homes allow an initial share as low as 10%, although the percentage available depends on the property.
Your deposit is normally calculated against the share you buy, not the full market value. If a home is worth £300,000 and you buy 25%, your share costs £75,000. A 10% deposit on that share would be £7,500 rather than £30,000 on the whole property.
The provider retains 75%, and you pay rent on that unsold portion. You may also pay a service charge, estate charge, insurance contribution and reserve-fund payments. Affordability should therefore be tested against the full monthly bill, not the mortgage alone.
Who Can Apply in England?
Applicants generally need a household income of £80,000 a year or less, rising to £90,000 or less in London. You must be unable to afford the deposit and mortgage payments for a home that meets your needs.
Eligibility commonly covers first-time buyers, previous homeowners who can no longer afford to buy, and existing shared owners who need to move. If you own another home, it normally must be sold by completion. Providers also carry out affordability checks.
The Real Costs
Mortgage, Deposit and Rent
You need a shared ownership mortgage unless you buy your share with cash. For a new-build home, rent can be charged at up to 3% of the provider’s share each year, although 2.75% is common. On a £300,000 home where the provider owns 75%, rent at 2.75% would begin at about £6,188 a year, or roughly £516 a month. Rent is normally reviewed annually.
Service Charges and Buying Fees
Service charges may cover communal cleaning, lifts, landscaping, management, insurance and major works. Ask for current figures, planned projects and any reserve-fund balance. Also budget for conveyancing, mortgage advice, surveys, moving costs and possible Stamp Duty Land Tax.
Repairs Can Be a Bigger Responsibility Than Expected
Shared owners often pay 100% of many repair and maintenance costs even though they own only part of the equity. Newer leases may include an initial repair period, with limited support for certain repairs. That protection may have partly expired on a resale property.
Read the key information document and lease instead of assuming the provider will pay its ownership percentage. For flats, major building works can create substantial service-charge bills.
How Staircasing Works
Staircasing means buying additional shares at the property’s current market value. As your share grows, rent on the provider’s portion falls. Most owners can eventually reach 100%, but some protected-area and specialist homes have limits.
The minimum amount depends on the lease. Newer homes may permit purchases of 5% or more and, in some cases, 1% each year for a limited period. Older leases may require 10% or larger steps.
Standard staircasing usually requires a RICS valuation, legal work and lender approval. Rising prices also increase the cost of future shares. Buying 10% of a £300,000 home costs £30,000; the same 10% costs £36,000 if the property later reaches £360,000.
Selling a Shared Ownership Home
You can sell at any time, but selling before reaching 100% is not always as flexible as an ordinary sale. You normally notify the provider first and obtain a RICS valuation. The provider receives a nomination period to find an eligible buyer for your share. Depending on the lease, this may last four, eight or twelve weeks.
If no buyer is found, you may usually market the property more widely, subject to the lease. Sellers can face valuation, legal and administration fees.
Advantages of Shared Ownership
The main benefit is a smaller deposit and mortgage than purchasing the whole home. It may provide access to a better location or more suitable property than open-market affordability allows. You can build equity in the share you own and may increase that share later.
It can also offer more stability and control than private renting. However, those benefits must be weighed against rent, service charges and lease obligations.
Disadvantages and Risks
Your monthly costs can rise through rent reviews, service-charge changes and mortgage-rate changes. You may carry full maintenance responsibility despite partial ownership. Renovations, subletting and keeping pets may require permission, depending on the lease.
Staircasing is not free, and buying later can become more expensive if the property appreciates. Falling values create a different risk: your share can lose value while selling costs still apply. Mortgage arrears or unpaid rent can put the home at risk.
How to Decide Whether It Suits You
Compare shared ownership with buying a smaller open-market home and continuing to rent while saving. Request the key information document before paying a reservation fee. Add the mortgage, rent, service charge, insurance, maintenance and a buffer for increases.
A practical stress test is to recalculate the budget with a higher mortgage rate, a rent increase and a larger service charge. If the plan only works at today’s exact figures, the purchase may be too tight.

Frequently Asked Questions
Do I own the property under shared ownership?
You own the percentage purchased through a lease and pay rent on the provider’s share. Shared ownership homes start as leasehold, including houses.
Can I eventually own 100%?
Usually, yes, through staircasing. Some Older Persons Shared Ownership homes and properties in protected areas limit the maximum share, so check the lease.
Is shared ownership cheaper than renting?
It can be, but not always. Compare the total mortgage, rent, service charges, repairs and fees with local rent rather than comparing rent figures alone.
Can I rent out a shared ownership home?
Subletting the whole property is generally restricted unless exceptional circumstances apply and the provider agrees. Taking in a lodger may be allowed, but the lease and provider rules must be checked.
A Route to Ownership, Not a Shortcut
The shared ownership scheme can make a suitable home accessible with a smaller initial deposit, but the lower entry cost does not remove the responsibilities of ownership. It works best for buyers with stable finances who understand the lease, can absorb rising charges and expect to remain long enough for the purchase costs to make sense. Judge the property by its complete long-term cost, not simply the percentage advertised.
