You can buy any value of share between 40% and 75% (sometimes even as low as 25% depending on the property). We usually advertise our developments at a 40% share as a starting point, but the share you buy is based on what you can afford following an affordability assessment. In time, you can always buy more shares if you wish to, which is called Staircasing, and in most instances (depending on the terms of the lease) you can go onto 100% outright ownership.
