UK Shared Ownership: Buy a Share of Your Home

June 16, 2026 3 min read

Shared ownership is one of the most practical ways to get on the property ladder if you cannot afford a full deposit. You buy a share of a property, pay rent on the rest, and can buy more shares over time until you own the whole thing. This guide explains how it works, who qualifies, and what it really costs.

What Is Shared Ownership?

Shared ownership is a government-backed scheme that lets you buy between 25% and 75% of a property. A housing association owns the remaining share, and you pay rent on that portion.

Key points:

  • You own the share you buy outright
  • You pay rent on the remaining share to the housing association
  • You can buy more shares over time in a process called staircasing
  • When you reach 100% ownership, you stop paying rent
  • Properties are typically new-build or resale homes through a housing association

Eligibility

To qualify for shared ownership, you must meet the following criteria:

CriteriaRequirement
Household incomeUnder £80,000 (under £90,000 in London)
Buyer statusFirst-time buyer, or previous owner who cannot afford to buy now
Age18 or over
Property locationEngland (Scotland, Wales, and Northern Ireland have separate schemes)

You do not need to be a UK citizen, but you must have the right to live in the UK permanently.

How It Works

The process is straightforward:

  1. Find a shared ownership property through a housing association or the Help to Buy agent in your area
  2. Choose a share between 25% and 75% of the property value
  3. Get a mortgage for your share, or buy with savings
  4. Pay rent on the remaining share to the housing association
  5. Staircase over time by buying additional shares when you can afford to

Staircasing

Staircasing means buying additional shares in your property. Most housing associations let you buy shares in 10% increments, though some allow smaller amounts.

Important points about staircasing:

  • Each time you buy more shares, the property is revalued at the current market price
  • You pay for the revaluation (typically £300–£500)
  • Legal fees apply each time you staircase
  • When you reach 100% ownership, you become the full owner and stop paying rent
  • Some schemes restrict how often you can staircase

Costs

Understanding the full cost of shared ownership is essential. You pay for more than just your share.

CostDetails
Deposit5–10% of your share (not the full property value)
MortgageOn your share only
RentOn the remaining share (typically around 2.75% of the unsold share per year)
Service chargeCovers maintenance of communal areas, buildings insurance, etc.
Stamp dutyMay apply depending on the property value and your share
Legal feesSolicitor fees for conveyancing
SurveyOptional but recommended

Rent Costs

Rent on the remaining share is set by the housing association. The typical rate is around 2.75% of the unsold share per year, though this varies.

For example, on a £300,000 property where you buy a 50% share:

  • Unsold share value: £150,000
  • Annual rent at 2.75%: £4,125
  • Monthly rent: £343.75

Service Charges

Service charges cover the upkeep of the building and communal areas. These vary widely:

  • Flat/apartment: £1,000–£3,000 per year
  • House: £0–£500 per year (if no communal areas)

Always check the service charge before committing. It can increase significantly over time.

Benefits

Shared ownership has several clear advantages:

  • Lower deposit: You only need a deposit on your share, not the full property value
  • Lower mortgage: You borrow less because you are only financing your share
  • Get on the ladder sooner: You become a homeowner even if you cannot afford a full purchase
  • Can staircase to full ownership: You can buy more shares over time until you own 100%
  • Some schemes offer subsidised rent: Certain housing associations offer lower-than-market rent rates
  • Part Buy to Rent schemes: Some allow you to rent your share instead of paying a mortgage

Drawbacks

There are downsides to consider:

  • Rent on remaining share: You pay rent every month on the share you do not own, and this increases over time with inflation
  • Service charges: These can be high, especially for flats, and tend to rise annually
  • Harder to sell: The housing association may have the right to find a buyer first, which can slow down a sale
  • Staircasing can be expensive: Each revaluation costs money, and if the property has increased in value, buying more shares costs more
  • Limited choice of properties: Not all areas have shared ownership schemes, and available properties may not suit your needs
  • Leasehold restrictions: Most shared ownership properties are leasehold, meaning you have restrictions on alterations and subletting

Worked Example

Here is a detailed comparison showing what shared ownership actually costs versus buying a property outright.

Shared Ownership: 50% Share of a £300,000 Property

ItemAmount
Full property value£300,000
Your share (50%)£150,000
Deposit (10% of your share)£15,000
Mortgage (90% of your share)£135,000
Mortgage rate (4% over 25 years)£540/month
Rent on remaining 50% (2.75%)£344/month
Service charge£100/month
Total monthly cost£984/month

Buying 100% Outright: £300,000 Property

ItemAmount
Full property value£300,000
Deposit (10%)£30,000
Mortgage (90%)£270,000
Mortgage rate (4.5% over 25 years)£1,350/month
Total monthly cost£1,350/month

Comparison

Shared Ownership (50%)Full Ownership (100%)
Deposit needed£15,000£30,000
Monthly payment£984£1,350
Monthly saving£366

Shared ownership costs £366 less per month, and you need half the deposit. The trade-off is that you only own half the property and pay rent on the other half.

Tips for Shared Ownership Buyers

  1. Check eligibility first: Make sure your household income is under the threshold before falling in love with a property
  2. Understand the full rent cost: Ask the housing association for the exact rent rate and what it covers before committing
  3. Plan for staircasing: Think about when and how you will buy more shares. Each step costs money for revaluation and legal fees
  4. Check service charges carefully: Ask for the current charge and the history of increases. High service charges can make shared ownership expensive
  5. Consider future resale: Some housing associations have restrictions on selling your share. Understand the process before you buy
  6. Get independent advice: Talk to a mortgage broker who specialises in shared ownership, and consider consulting a financial adviser
  7. Budget for rent increases: Rent on the remaining share typically increases with inflation (usually RPI or CPI plus a percentage)
  8. Read the lease: Shared ownership properties are leasehold. Understand what you can and cannot do with the property

How to Apply

  1. Check your eligibility using the government’s shared ownership checker or your local Help to Buy agent
  2. Register on your local housing association’s waiting list
  3. Look for available shared ownership properties on the housing association’s website or through the government’s portal
  4. Apply for a shared ownership mortgage through a broker who specialises in the scheme
  5. Complete the purchase with a solicitor

Summary

Shared ownership is a practical route onto the property ladder for buyers who cannot afford a full deposit. You buy a 25–75% share, pay rent on the rest, and can staircase to full ownership over time. The main benefits are a lower deposit and lower monthly payments. The main drawbacks are rent on the remaining share, service charges, and potential difficulties when selling. Always check the full costs, understand the staircasing process, and get independent advice before committing.
