In addition, the society is offering free legal services for remortgages.
The two-year discount mortgages are available at current rates of 2.45% up to 75% loan to value (LTV), at 2.95% up to 80% LTV and at 3.75% up to 85% LTV. All tiers of the product allow 10% capital repayments each year without penalty, have no higher lending charge and a booking fee of £199.
Kim Rebecchi, Leeds Building Society's sales and marketing director, said, "We are delighted to get 2011 off to a great start by converting our two year discounts into a New Year sale mortgage range.
"The removal of the £800 completion fee and the addition of a free standard valuation up to £335, on rates beginning at only 2.45%, means it really will be a happy new year.
"Households see a significant increase in expenditure after the festive season. This will be exacerbated this year by the increase in the rate of VAT to 20%.
"Therefore, the opportunity to minimise the cost of the biggest monthly outgoing will be welcomed and this sale product provides this. These fees assisted products are ideal for purchases and remortgages alike."
