Shared Ownership Mortgages

A shared ownership mortgage could help you get onto the property ladder. Find out how they work here.

What is a shared ownership?

Shared ownership is a type of mortgage. It’s different to a residential mortgage, as instead of buying the whole property, you buy a share. You’ll pay a mortgage on your share, then pay rent on the rest. 

If you’re a first time buyer, saving a big deposit can be tricky. That’s where shared ownership mortgages can help. They’re also known as ‘part buy, part rent’ mortgages and are offered by housing associations.

Shared ownership mortgages could allow you to buy between 25% and 75% of a property with a housing association, paying rent on the rest. To get started, all you need is a 5% deposit towards the part of the home you’re buying.

Who can get a shared ownership mortgage?

Shared ownership mortgages are available to people living permanently in the UK who are: 

  • First time buyers. 

  • Previous homeowners that now can’t afford to buy. 

  • People who already live in a shared ownership home. 

  • People who are renting a council or housing association property. 

  • Households that earn less than £80,000. The limit goes up to £90,000 if you live in London. 

How do I apply for a shared ownership mortgage?

It’s easy to get started. Just contact your nearest housing association to apply for the shared ownership scheme. 


You’ll be asked questions about your: 

  • Income 
  • Savings 
  • Credit history 
  • Preferred location 
The amount you can borrow will normally depend on your: 
  • Income
  • Mortgage cost
  • Rent
  • Service charges
  • Ground rent
The minute you’ve been accepted it’s time to get excited – you can start looking for your new home. 

Shared ownership: pros and cons 

Advantages of shared ownership

  • You can buy the part of the home you’re renting out at a later date.
  • Gives you a chance to own your home, even without a big deposit.
  • You pay rent on a property that you have a chance of eventually owning.
  • You can sell your shared ownership at any time, even if you don’t fully own it. 

Disadvantages of shared ownership

  • When selling your home, the housing association may not give you full control over who you sell to.
  • You have to pay ground rent and service charges on your home.
  • If you’ve purchased a flat, you might need to pay maintenance charges for communal areas too. 
  • How does shared ownership work when you sell your home?

    It’s worth knowing that the housing association will have the first option to sell your property before you do.

    This is called ‘first refusal’ and means they can find their own buyer if they want to. This is also the case if you don’t own a full share of your property at the end of your tenancy.

    Can you build an extension on a shared ownership house?

    You’d need to get permission to add an extension. You can ask the housing association for this. 

    Can you buy a shared ownership house outright?

    You can buy a bigger percentage of your home at any time. This is called ‘staircasing’.

    You may be able to buy a 10% share of the overall value of your shared ownership home. To buy any bigger percentage than that, you may have to pay extra.

    The amount you’ll have to pay to increase your share depends on how much your home is worth. You can find this out by paying the housing association to carry out a valuation.
