The Financial Services Authority is taking further steps to tighten up on rogue sellers of lifetime mortgages, the products used by elderly homeowners to supplement income in retirement. The moves follow a damning report last week from Which?, the consumers' association, and the FSA's own mystery shopping research carried out last year, which revealed that over 70 percent of homeowners who took out an equity release scheme have been badly advised because the intermediary failed to carry out a full fact find. The FSA says another mystery shopping exercise is a 'top priority' with a review of lifetime mortgage advice and any subsequent investment advice given to homeowners.
