Just be careful about having banks run your credit - it puts a small dent in your credit score by something like 5 points and lasts for 2 years, so don't go to 5 different banks getting checks
The credit reporting agencies all allow for rate shopping on loans like car and house loans.
All inquiries in a months or so period count as one.
And it isn't a 5 point hit that lasts for the two years. It fades as time goes on. After a year it is already half that.
