Borrowers can access a three-year fixed rate at 60% Loan to Value at 2.59%, with a 75% LTV fix from 2.89%.
Existing borrowers will continue to be offered mortgage rates 0.10 percentage points lower than new business rates.
The mutual has also cut the fee on its first-time buyer products to £400. Also, remortgage borrowers will receive a free standard valuation and the choice of either free standard legals or £250 cashback, payable one month after completion.
Tracie Pearce, head of group mortgages at Nationwide, (pictured) said: “Nationwide is demonstrating that it really is open for business by announcing its fourth rate cut in January alone.
“These reductions clearly demonstrate our commitment to offer competitive, quality and affordable products to both new and existing customers, at all LTVs.”
