With shared ownership you buy a share of a home (usually 10% to 75%) with a mortgage and pay rent to the housing association on the rest — typically 2.75% of the value of the unsold share a year, rising each April.
You also pay any service charge. Later you can buy more shares (staircasing) at the market value at that time. The table compares the monthly cost of owning different shares.
