Keystone Property Finance has reduced rates across its buy-to-let range, with cuts of up to 20 basis points as the specialist lender seeks to bolster its offering to brokers and landlords.

The lender has announced a 20 basis point cut on all its ex-pat buy-to-let products, while the remainder of its range — excluding holiday let loans — has been reduced by 10 basis points.

The move means Keystone’s standard two-year fixed rate now starts at 2.94% at 70% loan-to-value, while the equivalent specialist product begins at 2.99%.

Other repriced products include a five-year fixed refurb to let option at 4.69% to 65% LTV, and a two-year fixed rate for ex-pat landlords from 4.54% at 65% LTV. Keystone’s holiday let range remains unchanged, with its five-year fix starting at 5.49%.

The lender has also repriced its product transfer/PT Plus and Switch & Fix options, which now start at 4.99% and 5.69% respectively, both at 65% LTV.

In parallel with the rate reductions, Keystone has rolled out a proprietary AI system to streamline its application process. The new software, launched last week, enables faster document upload and labelling via the lender’s broker portal, aiming to reduce processing times and improve operational efficiency.

Elise Coole, managing director of Keystone Property Finance, said: “These rate reductions, alongside the recent launch of our AI-powered document upload and labelling technology, are designed to enable brokers to increase productivity and maximise lending for their landlord clients with ease.

“This month’s updates are the latest steps in our ongoing investment in both product innovation and broker support.”
