Market Harborough Building Society has launched a series of limited-edition mortgage products aimed at borrowers seeking loans between £3 million and £5 million, with rates starting from 4.30%.

The complex case specialist has added four new two-year deals to its residential range: a fixed rate at 4.30% with a 2% fee; a discount rate at 4.35% with a 2% fee; a fixed rate at 4.84% with a 1% fee; and a discount rate at 4.89% with a 1% fee.

The products are designed for borrowers with non-standard income, self-employed applicants, those lending into retirement, or buyers with complex property or ownership arrangements such as joint borrower, sole proprietor.

The society will also consider up to six times income, subject to affordability.

Iain Smith, head of mortgage distribution at Market Harborough Building Society, said: “Our brokers have told us they want more choice for their larger loan clients. Our new limited edition deals mean we’ve increased the range of rate/fee options to suit different needs.

“This ensures we’re well-positioned to support larger loan borrowers, including high net worth individuals. It’s all part of our promise to stay responsive, flexible and easy to do business with.”
