Buying more shares in your shared ownership home (staircasing)

Costs involved in buying more shares

Your landlord may charge an administration fee each time you buy a share of 5% or more. Check the administration fee amount you need to pay with your landlord.

There may also be legal fees and valuation fees to pay.

If you need to remortgage to buy more shares, you may need to pay mortgage fees to your lender.

How much stamp duty you will pay

You pay stamp duty land tax on a purchase of property over £300,000.

There are discounts for first-time buyers.

How it works on properties of £300,000 or over

You can pay stamp duty land tax on a shared ownership home in 2 ways:

  • make a one-off payment
  • make a payment when you first buy and then pay in stages once you reach more than 80% ownership

You can choose which option’s best for you, depending on your circumstances.
