An investor is considering refinancing a property. The current mortgage has an interest rate of 8.75% and a mortgage balance equal to 45% of the property value due to amortization of the loan and some appreciation in value. However, the investor would like to refinance at an amount equal to 75% of the property value. He has found out that the property can be refinanced at a 75% loan-to-value ratio over 15 years. What can be said about the incremental cost of refinancing?
