24 years left on a 30 year fixed rate mortgage (5.875%) I am 60 years old. What should I do?I currently pay 1774 a month and add another 300. a month on the principal. By the time I retire in 6 years I hope to be able to sell the house and buy something smaller.Should I remortgage at 4.489% APR for a 20 year mortgage? The closing costs are about $6000. Is it worth it considering the closing costs? Is there a formula to find this out? continue paying $1700. a month mortgage. I currently add $300. each month to the principal. I will have to sell this house when I retire and move to a less expensive house. Keep paying on this mortgage and Geta September 27 2009 - Manassas00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
