Even though mainstream mortgages comprise more than one in eight of those packaged by the survey's respondents, they are not considered to be as important as other types of business.
Indeed only 11 per cent of those asked said that mainstream business is vital to packager success going forward, whilst 13 per cent didn't feel as though these mortgages were important at all to their future business as a packager.
Nigel Payne, managing director TMB, said: “It is encouraging is that packagers are able to benefit from healthy markets such as self certification and buy-to-let. Being able to rely on these markets means that packagers will be able to fill any gaps in their income with the healthy returns that can be generated in these sectors.”
