Are there specific interest rates for new build mortgages?
Yes, some lenders will offer specific deals for a new build property but others will simply see them as part of their home mover or first-time buyer packages. Tailored interest rates that lenders offer for new build mortgages can be slightly higher than the rates for other types of properties and that’s because there’s a possibility that a new build could quickly lose its value.
Whether you’ll be at the higher or lower end of the rates scale will depend on multiple factors including your credit history, deposit, and income. A mortgage broker would be able to assess your situation and provide an estimate of the rate you could expect on a new build mortgage.

Exclusive deals for first-time buyers
There are some new build mortgage deals that are only available to those buying for the first time. They might be offered by the government, mortgage providers or even the housing developers themselves.
Examples of these include:
- First Homes scheme: This is a government scheme that allows first time buyers in England to purchase a new build, or a home originally part of the scheme, at between 30% and 50% lower than its market value. This would lower the mortgage size you need and could equate to a lower interest rate.
- Mortgage guarantee scheme: Another government initiative, this allows those with as little as 5% saved as a deposit to obtain a mortgage. The government offers lenders a guarantee to mitigate some of the risk there can be in an applicant with such a low deposit and this could potentially influence the interest rate.
- Deposit unlock: When an applicant only has between a 5% and 10% deposit, some lenders allow for the house builder to insure the mortgage. This again reduces the risk for the lender and could impact the rate they offer.
- Developer deals: Some developers, at their own discretion, offer various discounts to new build buyers, including those who are buying for the first time. Barratt Homes for example, can boost a 10% deposit by 5%, Persimmon Homes can cover up to 10 monthly mortgage payments and Taylor Wimpey could contribute up to £12,000 towards a mortgage.
Other options that might be worth considering include a guarantor mortgage, Shared Ownership mortgage or a Lifetime ISA.
