Changes your costs dramatically.
Also omitted was the fact you can refinance to capture a lower interest rate. I have yet to own a home I did not refi. 1 week ago I got a 5.9% quote from chase bank on a 30 year fixed. Rates are always moving. I suspect I can find 5.5% on a 15. I refinanced one house 7 times in 10 years. Had a broker with me on speed dial. Told him anytime you can lower my cost 1/4% on a no cost refi call me!
