NSSE is targeted mainly to help first-time buyers on low to moderate incomes. However, families of children with exceptional healthcare needs may qualify for assistance if they need to move to a larger or more expensive property due to the needs of the child. Shared equity generally allows a buyer to pay between 60 to 80 per cent of the price of a home, with the remainder paid for by the Scottish Government. The buyer owns the whole of the property, but the Scottish Government holds a security over the proportion of equity stake it has funded, the value of which will go up or down with the value of the house.
