Chris Smith, senior product manager for mortgages at Yorkshire, says: “Our new range of mortgages for people with a 15% deposit offers great value and a variety of options to suit borrowers’ pockets.
“Our fixed rate deals offer piece of mind when it comes to mortgage repayments for those who are concerned about possible future interest rate rises. The tracker deals offer a lower initial rate with the flexibility of having no early repayment charges after two years, meaning we should have something that will appeal to everyone.”
