re: No cost refi offer

If you know for 100% certain that you will be in that home and that mortgage for 15 years... then look at options with costs.

The average lifespan of a mortgage is about 5 years by the way (sell the home and payoff, refinance for lower rate, or refinance for cash out).

For what it is worth, if your loan was over $250k+, i would encourage you the other way (looking at a 2 year payback of the costs).
