a system in which a person who lives in a house or flat buys part of it and pays rent on the rest, usually to a local authority (= the government of a town, city, or local area)

Shared ownership really only works where the purchaser expects that future salary increases will allow them to eventually own the property outright. 房屋产权共享只有在购房者预计将来的工资涨幅能让他们最终能拥有完全产权的情况下才行得通。

Only key workers and other buyers using shared ownership schemes saw a reduction in duty. 只有关键工作者和使用共有产权计划的其他购房者的税收得到了减免。
