When you go through a bank for your mortgage, they're going to start looking into the possibilities of bringing over your personal accounts and credit cards. Do you really want to feel pressured into anything else? You're already dealing with all you can handle in a mortgage. Mortgage brokers are able to offer you better rates as well because they have a vast number of opportunities to shop around at, rather than just the few that banks have. Most of all though, mortgage brokers offer you what you need, personalized service to fit your needs and expertise on the subject of mortgages. It is the only thing they deal with, so why would you trust your mortgage in the hands of someone who works with mortgages only two hours a day, as opposed to eight? They are trained professionals that understand the ins and outs of a mortgage and can choose a mortgage to fit your needs.
