Tracie Pearce, head of group mortgages at Nationwide, said: “This re-price is aimed at helping those who need it most – first-time buyers.
“Our mortgage lending currently helps more than one in every five first-time buyers get the key to their own front door.
“As we announced earlier this week, our Save to Buy scheme has proved to be a great success and in the last three years, we have helped thousands of aspiring home buyers.
“Whilst we look to maintain all round competitiveness in our pricing to help maintain the healthy recovery in the housing market, our main priority is providing affordable mortgages to first time buyers and customers with low deposits.”
