How much deposit do I need for shared ownership?

You typically need a 5-10% deposit on the share you're buying, not the full property value. For example, if you're buying a 25% share of a property worth 200,000 pounds, you'd need a deposit of 2,500-5,000 pounds.

What is staircasing in shared ownership?

Staircasing is the process of buying additional shares in your shared ownership property. You can typically buy shares in 10% increments until you own the property outright (100%). The price is based on the current market value.

How is rent calculated on shared ownership?

Rent is typically charged at 2.75% per year of the housing association's share value. For example, if they own 150,000 pounds worth, annual rent would be 4,125 pounds (about 344 pounds per month).
