Important Information
What is Shared Ownership?
You buy a share of the property (typically 25-75%) and pay rent on the remaining share to a housing association.
Additional Costs
Remember to budget for additional costs such as surveys, legal fees, buildings insurance, and potential staircasing fees.
Affordability Guidelines
Most lenders recommend housing costs should not exceed 35-40% of gross monthly income.
Staircasing
You may be able to buy additional shares in the future (staircasing) to increase your ownership percentage.
