That spread will be much different depending on the size of the loan. Depending on the state you live in, most are relatively standard showing roughly $2300-3000 in closing costs on average considering a zero point loan, although some states are more expensive because of higher title fees, appraisal costs, surveys and state taxes. New York and Florida come to mind as high-cost mortgage states. If your balance is smaller, you'll see a higher spread between rate and APR because the fixed costs to finance are larger in proportion to your balance. With a larger loan amount this spread will be smaller and you'll have more opportunity to offset your costs with negative points, which will reduce or eliminate the costs ("no-cost" loan is done by giving a rate higher than what you qualify for). I know your topic is from a long time ago, which likely means this is long over, but do you know where your costs landed? BE of 7 yrs is a long time on refi, but 3.625% on a 30 yr fixed is pretty damn slick.
