Keystone Property Finance is the lending brand of Mortgages for Business. Originally set up to help brokers source specialist buy to let finance, Keystone has broadened its offering to include commercial mortgages, short term and auction finance. Funding lines for Keystone product ranges are supplied by Paratus AMC and Together Money.

Keystone is particularly good at helping brokers who are struggling to find a home for complex buy to let deals. Our business development managers are well known for going the extra mile and because they have direct access to the underwriting team 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?

If you would like to place a case, please make sure you register with us first. Registration forms can be downloaded from the Keystone website. Remember, we are fast payers! As soon as we’ve been paid for a completed case, you’ll get paid. We make payment runs twice a week, so you’ll never be kept waiting and we’ll make sure that each payment is properly referenced to help keep your recordkeeping in order.
