But Aaron, if I dont break this year, then I wont be able to claim for the next 4 years.
Also the cost of the break fee is offset well and truly by (i) tax deduction of the break fee (ii) the new 4.79% compared to the current 5.69%.
On a 500k loan, I think it averages out better. By being able to pay interest in advance, it means I get back about 8 to 9K each year as a tax deduction by going interest only in advance.
