Figure out your monthly payments with this handy calculator.
This scheme allows you to own 100% of your home and only pay 80% of the price upfront. You provide the 5% deposit and the government will lend you up to 20% as an equity loan. You can then apply for a mortgage based on the remaining 75% of the house price.
The equity loan is interest-free for five years and the scheme is available on new build homes up to the value of £600,000.
