The answer is: Lower;higher
Longer loan duration would provide more risk for the lender, Because of this, the annual interest rate for long term loans tend to be higher compared to short term loan.
When comparing 30 year loan and 15 year loan, the payment that Jocelyn will make for 30 year loan would be cheaper. But, since long term loan has higher annual interest rate, the accumulated cost would be higher when it reach maturity date.
