Mortgage Next's managing director, Gemma Harle, said: “Despite all the downbeat talk about the housing market, the buy-to-let sector continues to show its resilience.
"This product will appeal not only to investors who are contemplating taking advantage of lower house prices to increase the size of their property portfolios, but also landlords who are considering remortgaging their existing buy to let deals.”
