I've learned a lot about personal finance over the years from Jonathan Ping of My Money Blog. One important lesson I learned from his blog posts about refinancing his home is that there's no reason not to refinance your mortgage repeatedly as long as you're coming out ahead each time. So I have, three times in five years. How and why did I do it, and how much money did I save? Find out in my latest Bargaineering post: I’m into serial refinancing … You should be, too.
