Market Harborough’s head of mortgage distribution Iain Smith said:

“We’ve significantly lowered rates across our larger loan range. This opens the door for more clients looking to borrow between £3m and £5m and ensures we’re well-positioned to support those borrowers with both simple and more complex circumstances, including high net worth individuals and expats. This follows a summer of enhancements across our residential solutions, which saw us acting on broker feedback to make it even easier for them to place their cases.”
This news comes after the Society recently made changes to boost client affordability, including relaxing its residential stress testing for cases up to £5m and increasing income multiples, with over 6x income now available under its tier three products and up to 6x income accepted under tier two products.
