The first-time buyer range includes a two-year fixed rated at 5.39%, a three-year fixed rate deal at 5.69%, and a five-year fixed rate deal at 5.89%, all up to 85% LTV.
The products can be taken out without paying any upfront fees, and include free valuation and legal fees, and £500 cashback.
Offset versions are also available with 0.10% added to the rate.
The deals are available through the building societies’ branches.
The Yorkshire is also offering a member-exclusive, five-year fixed rate deal at 6.49% available up to 90% LTV with free valuation and legal fees.
First-time buyers wishing to take up the deal have to been either a Yorkshire member for over 12 months or have a close family member or friend who has been a Yorkshire member for over 12 months.
A product has also been launched by the building society to help aspiring first-time buyers save for a deposit.
The account pays an interest rate of 2.05% gross per annum which includes a bonus payable when the customer is issued with a full mortgage offer.
If savers go on to take out a mortgage with the Yorkshire they will receive £100 cashback.
Tom Girling, product manager for mortgages at Yorkshire Building Society, says: “With signs of increased activity in the first-time buyer market, we wanted to make sure that we had a comprehensive range of mortgages for those looking to take their first step on the property ladder.”
