If you’re a first-time buyer in England, you can apply for a Help to Buy: Equity Loan. This is a loan from the government that you put towards the cost of buying a newly built home. You can borrow a minimum of 5% and up to a maximum of 20% (40% in London) of the full purchase price of a new-build home. You must buy your home from a homebuilder registered for Help to Buy: Equity Loan. The amount you pay for a home depends on where in England you buy it.
