Should I keep most of my banking, credit, and investment accounts at the same bank?
I've had all my account with the same bank for all my life. Generally, the disadvantage is that if I want some kind of product like a credit extension or a mortgage, I have the one bank to go to and if they don't want to help me I'm out of luck. However, occasionally there are also perks like the bank spontaneously offering you increased credit or even a whole line of credit. They can do this because they have your whole history and trust you.
