            1. A borrower has secured a 30 year, $110,000 loan at
8%.  Fifteen years later, the borrower has the
opportunity to refinance with a fifteen year mortgage at
7%.  However, the up-front fees, which will be paid in
cash, are $3,000.
- What is the monthly payment on the initial loan?
 
- What is the loan balance and the new monthly payment at the
time of refinancing?
 
- What is the return on investment if the borrower expects to
remain in the home for the next fifteen years after
refinancing?
 
- Suppose you can earn a risk-free return of 3% on your $3,000 at
the time of refinancing. Would the refinancing be a sensible
choice?
 
Does anyone know how to solve these four problems with the
details?
