Furness Building Society is set to launch a 90% LTV product across England, Scotland and Wales.
The offering is a 2-year fix at 3.49% which has a £999 fee.
The deal will be available to first-time buyers, home movers and remortgages.
It will also offer free legals and valuation fee package on standard remortgages in England and Wales, with an incentive package for Scottish cases.
Previously, the lender had restricted 90% LTV products to its heartland area, LA postcodes.
The product will be accessible from Monday 14 December.
Alasdair McDonald, head of intermediaries at Furness Building Society, said: “We’re delighted to be able to lend at 90% LTV on a UK wide basis again.
“We’ve got some fantastic relationships with brokers in the high LTV market and it’s great to be able to go out to them with a competitive rate alongside our flexible and individual approach to underwriting cases.
“As with all 90% lending, we’re happy to look at new build houses, gifted deposits from close family and of course, our joint applicant, sole borrower proposition.
“Throughout the pandemic, we’ve worked hard to be there for brokers and it hasn’t been without challenges, but we’re delighted to be able to lend at 90% again throughout the UK.
“As a mutual, it’s also important for us to keep our local proposition going for customers living close by.”
