Does anyone have input on whether it would be smart to use sale proceeds of selling one house towards paying down another mortgage? When I look at the principal I paid down at the end of the year, it makes me sick!

if you talk to any financial planner, they all will tell you "Cash is King".. Realistically, if you have another mortgage, it's very likely your interest rate is at or below 4%.. and with the right financial adviser/planner, it's conservative to say you would make more than 4% on your money in most investment vehicles.. so if you can earn more than your spending, yet be allowed to write off the interest you're paying, then those funds should absolutely go into a brokerage account. If your current loan terms "Makes you Sick!!", then I would suggest you refinance into a 15 year mortgage.. the payment will be higher, but at today's' rates, from the very first payment nearly 60% of your payment would go towards principal, and you would still have an interest write-off..
