15 year mortgage vs 30 year paid off in 15
Consider the "opportunity cost" of the extra repayment on a 15 year loan.  If you owe money at 30% p.a. and money at 4% p.a. then it is a no brainer that the 30% loan gets paid down first. Consider too that if the mortgage is not tax deductable and you pay income tax, that you do not pay tax on money you "save". (i.e. in the extreme $1 saved is $2 earned). Forward thinking is key, if you are paying for someone's college now, then you would want to pay out of an education plan for which contributions are tax deductable, money in, money out. In my country most mortgages, be they 15,25,30 years tend to last 6-8 years for the lender. People move or flip or re-finance.  I would take the 15 for the interest rate but only if I could sustain the payments without hardship. Maybe a more modest home ?   If you cannot afford the higher repayments you are probably sailing a bit close to the wind anyway.   Another thing to consider is that tax benefits can be altered with the stroke of a pen, but you may still have to meet repayments.
