Also runs the FCA MCOB 3A high net worth check: on a regulated bridge, an applicant with annual net income of at least GBP 300,000 OR net assets of at least GBP 3,000,000 can have a term up to 60 months instead of the standard 12-month cap. Calculated by Fox Davidson, whole of market UK mortgage brokers authorised and regulated by the FCA (FRN 1056214).
