The rate cuts apply to mortgages at 75 per cent LTV, 85 per cent LTV and 90 per cent LTV.
Yorkshire Building Society direct mortgage manager Chris Smith says: “By offering £1,000 cashback we are giving first time buyers real support towards the cost of getting on the property ladder.
“Thanks to our range of competitive mortgages and the personal service we provide, we have seen the number of first time buyer mortgages provided increase by about a third this year.
“We expect these changes and our ongoing commitment to helping all borrowers, whether they have a large or small deposit, will allow us to help even more first time buyers.”
“First time buyers can apply for a Yorkshire mortgage online, over the telephone or in branch, though 90% LTV products must be made on an advised basis in branch.”
