A Shared Ownership (SO) lease is the legal document that describes in detail what percentage you own of your property. You are able to purchase a higher percentage of your property by serving Notice on Thrive so that you can own more of it at any time, this is called Staircasing.

Your lease also sets out what you (the leaseholder) is responsible for and what Thrive (the Freeholder) is responsible for. Thrive will usually carry out services and maintenance to the communal parts of the block or estate, all of which you contribute towards through your service charge. All repair within your home will be your responsibility.
