While other lenders have launched sub-4% rates at 60% or 65% LTV, Virgin is introducing a five-year fixed rate at 3.99%, available up to 75% LTV with £300 cashback.
The new product launch comes as Virgin reduces rates in its purchase and remortgage ranges by up to 0.29%.
Alongside the sub-4% rate, products in the purchase range with £300 cashback include two-year fixed rates at 65-75% LTV at 4.43%.
