People who are unable to afford the mortgage for 100% of a property, may be eligible for properties under Shared Ownership schemes.
Shared Ownership schemes usually allow you to purchase a minimum 25% share of a property and pay a small rent on the remaining percentage. The rent is normally payable to a Registered Provider of housing (also called a Housing Association) which owns the property.
Most schemes permit the option to buy a greater part of the property, as and when you are able to afford it. This is called 'Staircasing'. Some schemes even permit this up to 100% ownership.
Shared equity is very similar to Shared Ownership but you do not pay rent on the other equity share.
