Not really. Even if I didn't pay it off or sell it, I can absorb an interest rate hike.
My monthly mortgage is about 6% of my monthly gross income.
Then you have no worries, and this article does not pertain to you, but to the millions of Americans who are spending half of their salary to pay "interest only."
I bought my first home in March 2005 at a fixed rate at 6% at 23. I would have gotten one a year earlier but in college I didn't know or care about credit and let 2 low balance cards go unpaid when I moved so I had to spend many months on credit repair. NEVER will I make that mistake again. I wish I had gone with 5% on a 5/1 though as I doubt we'll be in there for that long and even if we do the amount of money saved off the first five years would easily offset any loss off of the next 1-3. Fortunately, my income is rising every year by leaps and bounds (up almost double in the last 2 years) and I expect that to continue for at least several more years. I intend to pay off principle more and more as my income level rises.
