Why? Dork32 can pay off the whole mortgage tomorrow if he/she wishes, and all $500K is earning a higher interest rate than 1.9%. Presumably Dork32 continues to accumulate wealth beyond that $500K. It would be utter financial malpractice to accelerate repayment of this mortgage in these circumstances, assuming the facts are as represented.
actually, i cannot pay off my loan tomorrow. i am in the lock in period. there will be a penalty if i pay off tomorrow.
but it is not going to hurt me as i am on a fixed interest rate till lock in ends.
the real issue to me is paying ABSD. It's quite a wishful dream that it would go up further. Besides higher purchase price would directly affect the rental yield. And if one is forced by circumstances to sell within 3 years, there is another round of SSD.
