The reductions apply across many of the firm’s residential solutions up to £3m, including expat cases.
The complex case specialist’s two-, three- and five-year standard residential fixed rate offerings have been cut by 0.15% for tier one fixed rates and by 0.2% for tier two fixed rates.
There are no changes to its larger loan rates for cases up to £5m.
For tier one cases with a £1,495 product fee, Market Harborough Building Society’s residential rates for cases up to £3m now begin from 5.04% fixed and 5.64% variable.
Iain Smith, the firm’s head of mortgage distribution, said: “We’re making these rate reductions off the back of our recent changes, which saw us raising the loan threshold across our standard residential solutions from £2m to £3m to support higher-value borrowing. The latest rate drops ensure we’re well-positioned to support clients with both simple and more complex circumstances.”
