Do you read? I said I consolidated the student loan into the HELOC so my rate is effectively 4% on it. I answered both questions already but here goes again. I said I didnt think rates were going up anytime soon. If I was certain I was moving in 3 to 5 years I would look into a ZERO cost refi into a 5/1 or 3/1 arm which is in the low 2% range and would considering making additional prinicipal payments with the savings. I know very good lenders who can do things without all the junk fees if you need help. IMO banking on selling your house to one of your neighbors isnt a plan its a prayer. Good luck with that one.
BTW, so after 30% down and paying a mortgage for about 10 years you have a 60% LTV. Sounds like zero appreciation. The house next door to mine sold 10 years ago and today would still sell for 40% more than that. Thats how things work around here.
