What changes the repayment?

TermA longer term can reduce the monthly payment but normally increases total interest.
OverpaymentsExtra payments can reduce the balance and potentially shorten the term, subject to lender rules.
Mortgage balanceThe amount borrowed is just as important as the rate and term.
