One additional advantage is that mortgage brokers tend to attract a high number of the most qualified loan officers. This is not universal, because mortgage brokers also serve as the training ground for those just entering the business. If you have a new loan officer and there is something unique about you or the property you are buying, there could be a problem on the horizon that an experienced loan officer would have anticipated.
A disadvantage is that mortgage brokers sometimes attract the greediest loan officers, too. They may charge you more on your loan which would then nullify the ability of the mortgage broker being able to "shop" for the lowest rate.
