Keystone Property Finance has formed a new technology partnership with valuation panel management firm Method to streamline the valuation process for brokers and landlord clients, including more complex cases such as HMOs and MUFBs.

The partnership makes Keystone the first lender to integrate Method xi, the firm’s API-driven platform, directly into its systems. An API, or Application Programming Interface, acts as a secure digital bridge that allows two separate computer systems to communicate with each other.

Before the integration, Keystone instructed valuers through a manual, multi-step process. The new setup automates that workflow, reducing administrative steps and speeding up case progression.

Once a valuation is instructed, Method’s platform scans the market to select the most suitable valuer for each case. Selection is based on factors including property location, cost, and agreed service level standards.

Keystone’s ability to implement the integration quickly reflects its use of a bespoke in-house system. Maintaining its own technology platform allows the lender to add new features or connect with advanced tools faster than lenders relying on off-the-shelf software.

Over the past 12 months, Keystone has increased investment in its technology stack. This includes rolling out an AI-powered document labelling system designed to cut administrative work for brokers. The lender has also partnered with LMS to use its Panel Link service, expanding access to panel solicitors for both limited company and personal name applications.

“Our goal is to remove the friction points that have traditionally made the mortgage journey feel slow and fragmented,” said David Whittaker, chief executive at Keystone Property Finance. “By being the first lender to go live with Method’s API integration, we have fundamentally streamlined our complex valuation workflow, replacing time-consuming admin with a smart, automated solution. This will particularly benefit HMO, MUFB and semi-commercial valuations."

“At Keystone, we don’t introduce technology for technology’s sake. We only invest in features that make a tangible difference to brokers’ lives. And our new partnership with Method is a perfect example of that.”

“We’re delighted to see Keystone utilising our direct integration ability that enhances speed and efficiency across the full valuation process for the benefit of brokers, borrowers and internal teams,” said Stephen Henman, managing director at Method.
