The low equity margin ( LEM ) is like a fee or percentage amount added to your interest rate. It is common where a buyer has a low level of equity or deposit, such as under 20%.
Once you reach the 20% point (such as through paying off more of your home loan and/or the home price appreciating), you may be able to apply for the low equity margin to be removed. You can talk to your bank or broker about this.
You might need to pay for a valuation report for this to be considered.
