You are entitled to buy additional shares in your home at any time after you purchase a shared ownership home. This process of purchasing additional shares and increasing your ownership is called Staircasing. The price you will pay for an additional share is relevant to a proportion of the current full open market value. The greater the share you buy in your home the less rent you will pay.
When you Staircase to 100% ownership you will pay no further rent to Hyde, however, there may be a monthly service charge payable. Some Share Ownership leases restrict Staircasing to 80% ownership to ensure that the property is retained for local people.
