The products are a 2-year fixed rate at 2.39% with a £1,295 fee and a 5-year fixed rate at 2.99% with £1,295 fee. Offset alternatives are available for each and are priced 0.20% higher than the non-offset equivalents.
Chris Smith, Yorkshire Building Society group direct mortgage manager, said: "For house buyers with a 40% deposit or home owners remortgaging, this provides a very competitive deal.
"Increasing the number of LTV levels at which we offer competitive products allows us to support an even wider range of people to buy or remortgage."
