hey you can go to a Broker, but they don't have access to all of the resources either. A broker can't always beat a bank if the bank is willing to haggle with you. It's silly talk to not shop around for the best rate. Talking to ONE broker doesn't necessarily give you the best rate.
It's also silly talk for a CFP to give out advice and not be more clear on it. Especially one who considers credit checks something more worthy of worry than the best interest rate on the biggest purchase of your life.
0.1% difference on a 5 year term makes thousands of dollars difference on a $250k mortgage. But hey, if you are more concerned about a couple of credit inquiries on yoru credit score, go right ahead!
