Depends on the broker, just ask him if there is a fee. TBH if there was no fee you're generally told up front so I would say there is possibly a .5% fee. Some people prefer to deal with a broker because they haven't time or the know how when it comes to choosing the best mortgage package. The broker provides a service to best suit your needs, but unfortunately like all professions their are good and bad brokers. Make sure they deal with a s many banks as possible, some only deal with 2 or 3 and therefore aren't providing an wide ranging service.
