📝 Complete Guide to Shared Ownership in the UK
This shared ownership calculator UK helps you understand the costs of part-buy, part-rent properties. Shared ownership is an affordable housing scheme where you buy a share (25-75%) of a property and pay rent on the remaining share to a housing association.
💰 How Shared Ownership Works
Shared ownership allows you to get on the property ladder with a smaller deposit and mortgage:
- Buy a Share: Purchase 25-75% of the property value
- Pay Rent: Pay rent on the unowned share (usually 2.75-3.5% of the value)
- Service Charge: Pay for building maintenance and management
- Staircasing: Increase your share over time (up to 100%)
- Leasehold: Shared ownership properties are typically leasehold
