Variable rates are great when interest rates are low and/or dropping. I was able to pay off the 25 year amortized mortgage on my current house in 11 years thanks in part to holding a fixed payment variable rate mortgage. The bulk of my monthly payments went against the principal because interest rates were steadily falling during the years I was making payments.
Just for the record mortgages on principal residences in Canada are not tax deductable. Nor are municipal property taxes for that matter.
I spent a couple of days with our large animal vet in Wisconsin. He always told me that cows are smarter than horses.
"If a horse gets tangled in some barbed wire fencing he'll struggle like crazy until he bleeds out or gets too exhausted to fight. A cow will just stand there, knowing that, eventually, someone will show up to set it free."
