Keystone Property Finance is an intermediary only lending brand owned by Mortgages for Business. Originally set up to help brokers source specialist buy to let finance, the current funding line for the Classic Range is provided by Paratus AMC.


Keystone is particularly good at helping brokers who are struggling to find a home for complex buy to let deals. The business development managers are well known for going the extra mile and because they have direct access to the underwriting team, they can often negotiate to get seemingly unworkable cases placed successfully.


Regularly out on the road, the BDMs take the time to get to know brokers in their patch face to face, over the phone and via email. So if you’d like to get a better understanding of our products and services why not arrange a meeting?


Keystone is on the lending panels of the following networks and mortgage clubs:




Julian Harris Network

Mortgage Advice Bureau


Primis (formerly First Complete & Pink)


Sesame Bankhall

Simply Biz

Tenet Lime
