The two-year fix offers an initial rate of 5.79%, with a £999 product fee and the five-year is offered at 6.35% with the same fee.
Mark Bullard, head of sales, NatWest Intermediary Solutions, said: “With the challenge of raising a large enough deposit still being the biggest issue for first-time buyers, I am delighted that we are able to offer intermediaries a choice of deals.”
The lender continues to offer a two-year fixed rate purchase mortgage for borrowers planning to use the Government-backed FirstBuy scheme.
The lender said it will also be increasing rates by 0.2% on a selection of fixed rate remortgages to bring them into line with the comparative purchase mortgages in its core and corporate ranges.
Further competitive 90% LTV deals are expected to be announced this week, pushing down rates further for first-time buyers with a 10% deposit.
