Mortgage brokers do the work of searching for the best deals and matching them up with your desires and qualifications. While some borrowers have the time and don't mind shopping from lender to lender while dealing with numerous people, building a new relationship with each new lender, brokers already have an established relationship with many lenders and the RIGHT broker will truly work to keep you informed and insure you are happy with the loans and services they provide to you. If your broker doesn't take the time to explain things to you that confuse you or that you think are surprises in the process, that broker may be over committed and too focused on one thing (making money) and sacrificing good service to get it. Remember, you are not locked into any broker until the deal is done and closed. If you are unhappy, you have the option of severing the relationship and moving on. The right broker can make all the difference, the wrong broker will leave you feeling frustrated and probably with less money in your pocket than you realize. It's a give and take relationship, deal with someone who gives equally as much (or more) as he/she takes.
