Help to Buy Explained

Help to Buy equity loans are open to anyone buying a new build home, whether you are a first time buyer or moving house. The new home you wish to buy must be no more than £600,000 and it must be your only property and the one you live in, you cannot use the scheme to buy-to-let.

How it works
You’ll need to have a deposit of at least 5% of the property price. The government will give you a loan for up to 20% of the price and you won’t be charged fees for the first 5 years of owning your home. But, you will need a mortgage of up to 75% to cover the rest.

In the sixth year, you’ll be charged a fee of 1.75% of the loan’s value. After this, the fee will increase every year. The increase is worked out by using the Retail Prices Index plus 1%. You must also pay back the loan after 25 years or when you sell your home – whichever is earliest. How much you pay back will depend on the market value of your home when it’s sold. You can pay back part or all of your loan at any time. The minimum percentage you can pay back is 10% of the market value of your home. The amount you pay will depend on the market value at that time.
