First Step has been designed to give people who have worked hard to save a cash deposit a realistic route into homeownership, while ensuring robust affordability and lending criteria. We’re pleased to bring this practical, intermediary-focused solution to market and to support brokers in finding the right outcomes for their clients.”
Sidney Wager, managing director of L&C Mortgages, said: “L&C Mortgages is delighted to partner with Newcastle Building Society in its launch of the First Step product, ahead of its full market release. We know that first-time buyers continue to face significant difficulty in building a big deposit to stand a chance of buying.
