Stephanie Charman, head of strategic relationships at Sesame Bankhall Group, said: “We are very pleased to be partnering with Buckinghamshire Building Society to provide our PMS and Sesame members with access to this competitive new buy-to-let remortgage product.
“This exclusive offering is being made available at a time when the market is experiencing record completion levels, so the timing is ideal.
“It will also help mortgage brokers to cater for the significant number of buy to let customers who have existing products coming to an end throughout 2021.”
Claire Askham, key account manager at Buckinghamshire Building Society, added: “We are delighted to support PMS and Sesame members by bringing more products to more people with our buy to let remortgage exclusive.
“Across the market, we are expecting to see an influx of buy to let clients in April as existing mortgages come to an end.
“Our flexible and bespoke underwriting approach means we can help brokers find the right solution for their clients.
“Furthermore, the non-search indemnity insurance can ensure a fast turnaround time and quick completion.”
