The mortgage rate you are able to attain when buying a home is dependent on many factors. Your credit score, buying points on your loan, and the type of loan you are getting (i.e.: 30 yr vs. ARM) are just a few of the things that can affect your mortgage rate.
Check with a lender to find out what rate they can get you when you are ready to purchase a home.
