You borrow $200,000 for 20 years with monthly payments at an interest rate of 8%. After 6 years of payments you are considering refinancing. The fees for all the paperwork will be $2,000. There is also 1.3 points charged on the amount borrowed. If the new interest rate is 6%, should you refinance? Explain using sound finance math.

Please show all steps used so that I can fully understand and follow along. Thank you so much!
