Assume you purchase a property for R400 000 and obtain the loan for the full amount.
This is called a 100% bond.
Your monthly premium over 20 years with a 10,5% interest rate will amount to R3 880.
If you pay off an extra R500 per month from month 1, your bond will be fully paid off after only 15 years and 7 months.
This means you save a total of R283,400 on bond repayments.
Imagine what you could do with that?
So yes, pay off your bond sooner to become richer.
