When you take out home and investment loans, Loan Reducer combines the loans and maximises the tax-deductible portion of your liability, thereby maximising your savings.
Your savings are maximised with a floor rate on your home loan and a ceiling rate on your investment loan.
You are paying your lender the same amount as you ordinarily would for the combined loan. However, the floor and ceiling rates ensure that the investment loan takes up the largest possible fraction of this sum. As investment property expenses are tax-deductible, this means you are effectively spending nothing on your investment loan whilst minimising your home loan, and therefore your total expenses.
How does the lender benefit by minimising my expenses?
Loan Reducer does not change how much you pay your lender because you save money by maximising your tax deductions. This means that your lender does not lose out on profit when you use Loan Reducer, but you still get to save.
