<prompt> Human: This is somewhat related to softcore churning. I recently cancelled a credit card with an annual fee after the first year signed up for the nice big fat cash bonus, so I expect my score to drop by about 3-5 pts? How does that affect your mortgage rate?Lets say I go to PenFed and they offer a 4 30-year mortgage. Are you qualified based on some tiered credit score therefore an increasedecrease of a few points would not matter?  <response>: I dont think my score affected my rate too much. At the time my wife and I borrowed, we got the best rate available 30 yrs at 3.5 but our score at the time was probably 720-730. So it was good - but not amazing. For some lenders, as long as youre over a certain point, youre eligible for the best rate. Some others might be more picky.
