"Cashback has been a growing feature on first-time buyer mortgages since the end of 2014, with 40% of first-time buyers opting for a cashback mortgage in 2016."
To be eligible, only one of the applicants is required to be a first-time buyer.
The products all feature a £500 cashback payment, and include two-year fixed rates from 2.72% and five-year fixes from 3.54% at 80% LTV.
The launch follows the introduction last week of a number of new 60%, 70% and 75% LTV Help to Buy shared equity mortgages.
Mark Bullard, Head of Sales, NatWest Intermediary Solutions, said: “Cashback has been a growing feature on first-time buyer mortgages since the end of 2014, with 40% of first-time buyers opting for a cashback mortgage in 2016. As part of our commitment to support first-time buyers, we believe that the addition of cashback, alongside our Help to Buy, shared equity and other first-time buyer mortgages offers brokers a really comprehensive choice for their customers.”
