Keystone Property Finance has secured a new funding line that it expects will materially increase its lending volumes across the buy-to-let market.

The facility comes from a well-known international investment bank and sits alongside the lender’s two existing long-standing funding partnerships. Together, the arrangements give Keystone additional capacity and greater flexibility to support a wider mix of borrowers.

The lender views the deal as a sign of confidence in both its own lending proposition and the resilience of the wider buy-to-let sector. With more capital available, Keystone plans to expand its reach while continuing to focus on operational delivery rather than narrowing its criteria.

Alongside higher lending capacity, the funding will support Keystone’s digital roadmap and efforts to improve efficiency across the business. Over the past 12 months, technology and process upgrades have been a central priority, with a series of initiatives already completed.

These recent developments include:

  • a technology partnership with valuation panel management firm Method, designed to streamline the valuation process for brokers and landlord clients, including more complex cases such as HMOs and MUFBs
  • a strategic partnership with LMS, which expanded Keystone’s panel of vetted solicitors for both limited company and personal name applications
  • the rollout of an AI-powered document labelling solution aimed at reducing administrative workloads for brokers and shortening offer times

Commenting on the funding, David Whittaker (pictured), chief executive officer at Keystone Property Finance, said: “This new funding line marks a pivotal moment for us as a lender and is a clear vote of confidence not just in our business model, but also the long-term future of the buy-to-let market." 

"With this additional capacity, we will not only be able to significantly scale our lending volumes but also support a much broader range of landlords in obtaining the finance they need. It will also allow us to accelerate our digital roadmap and further streamline our processes. This means we will be able to provide an even slicker service to brokers, helping us to cement our place as a leading lender in the specialist buy to let market.”
