Shared Ownership is the most established affordable home product to assist in buying your first home. You initially can buy between 25% – 75% share in a new build property or buy the share the current shared owner or more on a pre-owned home. When selling or buying more shares (staircasing) in a shared ownership property there are procedures to follow to ensure the property remains available for those who otherwise would not be able to buy on the open market and to ensure a fair valuation is given to buy additional shares. A shared ownership home is also to be your main home and therefore generally cannot be sublet unless in exceptional circumstances. The shared ownership lease will explain the procedures you have to follow.
