You purchased a beautiful one bedroom condo five years back for $336,000, with 20% down, and 3.90% interest for 30 years (semi-annual compounding), making monthly payments of $1,263. Your brief excel calculation tells you that so far, your total equity in the apt is $93,396. Not bad. However, the interest was fixed for only 5 years, and now you have to renew the loan for the rest of 25 years. You expect your interest to be 2% higher this time around. How much more (or less) will you have to pay every month? (round answer to closest integer, do not put in a dollar sign - for instance 115 , not \$115.2)
