Early repayment of a Mortgage loan can make a significant reduction of the loan term. If your loan structure allows this, you should pay extra each month when you can as the cumulative effect of compounding interest costs over a long term can be significant.

Again, if the structure allows it, a Line Of Credit style Home equity loan structure can minimise your overall interest costs if you can have your wages entirely paid into the account initially as the small residual amount you would otherwise have in a non-interest-bearing account will now accumulate significant interest savings over the life of the loan.
