This is a change from 80% across its foreign currency mortgage range, which is open to expat and foreign income borrowers, including first-time buyers.
The products are also available to borrowers who are buying property in Scotland.
Darlington Building Society said foreign currency and expat lending were key areas of growth and the latest change would offer more flexibility.
Chris Blewitt, head of mortgage distribution at Darlington Building Society, said: “We have seen steady demand from brokers placing foreign currency and expat cases, but the feedback has been consistent where higher deposit requirements can make those cases harder to progress.
“By increasing the LTV to 90% from 80%, we are giving brokers more flexibility to support clients who have the income to sustain the borrowing but may not have built up a larger deposit, particularly first-time buyers. This also extends to borrowers purchasing property in Scotland, where we are continuing to support cases across a broader range of locations.”
