Yes, you can. Once you’ve lived in your home for a certain amount of time, which will be set out in your lease, you’ll be able to buy more shares so that you own a bigger portion of the property. You can do this in stages, usually until you own 100% of the property if you wish. You’ll need to increase your existing mortgage or remortgage for the new amount. Whether you can do this will depend on whether you meet the lender’s criteria. There will be costs involved that you’ll need to budget for.
