The $20,000-Per-Year Question Every Property Investor Should Ask
Discover why paying off your investment loan faster might be costing you thousands — and what smart investors do instead.
The Common Mistake
Many property investors focus on one goal only: paying down debt as fast as possible. But from a cash flow and tax point of view, that’s not always the best approach.
It’s natural to want to eliminate debt. We’ve been taught that debt is bad and that paying it off quickly is always the smart move. However, when it comes to investment property debt, this conventional wisdom can actually cost you tens of thousands of dollars over time.
The key insight that separates experienced investors from beginners is understanding the difference between “good debt” and “bad debt” — and knowing how to make your debt work for you rather than against you.
Let’s Look at a Simple Example
Assume you borrow $1,000,000 at an interest rate of 5.5%. Your annual interest cost is $55,000.
Instead of using surplus cash to reduce the loan, you invest that money into an income-producing investment earning 7.5%. That investment generates $75,000 per year.
Before Tax Calculation
This simple calculation shows a $20,000 annual advantage. But the real power of this strategy becomes apparent when you add the tax angle.
The Tax Advantage
Because the loan is used for investment purposes, the interest is generally tax-deductible. This means the real cost of the loan is lower after tax.
Key Tax Insight
For investors on a 47% marginal tax rate, a $55,000 interest deduction could reduce your tax by around $25,850. That means your after-tax interest cost is closer to $29,150, not $55,000.
Meanwhile, the investment income may be:
- Taxed at a lower effective rate
- Partly tax-deferred
- Offset by other deductions
After Tax Calculation (47% Tax Bracket)
When you compare the after-tax cost of borrowing ($29,150) against your investment returns, the advantage becomes even more significant. This is the power of strategic debt management.
“Is my debt working for me?”
The smarter question is not “How fast can I repay my loan?”
What This Means for Investors
With the right structure, you may be able to leverage multiple advantages simultaneously. Here’s what experienced investors focus on:
Using the Bank’s Money
Leverage allows you to control more assets with less of your own capital.
Keeping Interest Deductible
Maintain the tax-deductible status of your investment loan interest.
Improving Cash Flow
Better manage your monthly cash position while building wealth.
Growing Wealth Faster
Compound growth on a larger asset base accelerates wealth creation.
This is why many experienced investors don’t rush to pay off “good debt.” Instead, they focus on whether their money is earning more than the after-tax cost of borrowing.
Important Consideration
Every investor’s situation is different. The right strategy depends on your income level, risk tolerance, investment goals, and overall financial position. Professional advice is essential to ensure this approach is suitable for your circumstances.
