decembersal - can I ask where else do you think the overpayment would be taken off other than from the capital amount?
I open this question to all by the way and not just yourself -I ask this question because I've seen a few posts now where this question has been asked
- the interest accrued on a mortgage is based on the capital balance - overpaying a mortgage accelerates the repayment of capital so there is a lower capital balance after each over payment - therefore the interest on the capital balance will be lower.
