Some properties are available to buy through a Shared Ownership scheme. This is where ownership of the property is shared between you and the landlord. You buy a portion of the property (between 25% and 75%). And the rest is owned by the landlord, to whom who you pay rent. You may be able to buy a larger share later on if you wish. 

This is a good option to consider if you would like to buy a home but can’t afford a full mortgage. Some housing associations and charities offer shared ownership schemes.
