Principal & Interest vs. Interest-Only Repayments: Which Loan Structure is Right for You?

When taking out a loan, one of the key decisions borrowers must make is whether to opt for Principal & Interest (P&I) repayments or Interest-Only (IO) repayments. Each structure has its advantages and drawbacks, depending on your financial goals and whether the loan is for an owner-occupied property or an investment. Understanding the differences can help you make an informed decision that aligns with your financial strategy.

Principal & Interest (P&I) Repayments

With P&I repayments, borrowers gradually reduce the principal loan amount while also paying the interest accrued. This results in higher repayments compared to an IO loan but provides a structured path toward debt reduction.

Pros of P&I Repayments:

  • Debt Reduction: Each payment reduces the principal, and you have a clear goal on when you will repay your principal loan amount in full.

  • Lower Overall Interest Paid: Since the loan balance decreases over time, borrowers pay less interest compared to IO repayments in the long run.

  • Faster Loan Repayment: Borrowers build equity faster, which is beneficial for those aiming to own their property outright.

  • Easier Refinancing: Lenders often view P&I loans more favorably when assessing refinancing applications.

Cons of P&I Repayments:

  • Higher Monthly Repayments: The inclusion of principal in the repayment means higher monthly costs.

  • Reduced Flexibility: Less cash availability compared to IO loans, which could limit investment opportunities or lifestyle choices.

Interest-Only (IO) Repayments

With an IO loan, borrowers only pay the interest on the loan for a set period (typically 1-5 years) before switching to P&I repayments. This structure is popular among property investors looking to maximize cash flow and borrowing capacity.

Pros of IO Repayments:

  • Lower Monthly Repayments: Since only the interest is paid, the borrower has more available cash flow for other investments or expenses.

  • Maximizes Borrowing Capacity: Lower repayments can improve serviceability for future loans, making it easier to expand an investment portfolio. For example, certain lenders assess current investment debt of other lenders on the interest only repayments

  • Tax Efficiency for Investors: Interest payments on investment loans are typically tax-deductible, making IO repayments more attractive for investors.

  • Increased Cash Flow for Reinvestment: Investors can use excess cash to purchase additional assets or cover property expenses such as maintenance and improvements.

Cons of IO Repayments:

  • No Reduction in Debt: Since the principal loan amount remains unchanged during the IO period, borrowers are not reducing their debt.

  • Higher Overall Interest Paid: When the loan eventually switches to P&I, the borrower pays more in total interest over the life of the loan.

  • Potential Refinancing Challenges: Lenders may scrutinize IO borrowers more strictly when assessing new loan applications.

  • Market Risk: If property values decline, borrowers with IO loans could find themselves in negative equity, making refinancing or selling more challenging.

  • Loan Affordability: Lenders generally offer IO terms based on your ability to show loan affordability on the remaining P&I term. For example, a 30 year loan may be structured on a 2 year IO term, and a 28 year P&I term. It is therefore, harder to show loan affordability on the reduced loan term.

  • Higher Rates: Certain lenders, especially in the non-bank segments, charge additional rate loadings for Interest Only terms.

Which Option is Best for You?

  • For Owner-Occupiers: P&I repayments are generally the better option as they reduce debt and build equity over time. Most lenders also either do not offer IO payments for owner occupied property or charge a premium to do so.

  • For Investors: IO repayments offer flexibility and enhanced borrowing capacity, making them ideal for those looking to grow a property portfolio. They are also better from a cash-flow perspective when managing investment properties, especially in times of scarce cash-flow from market conditions.

  • For Short-Term Strategies: IO loans can be advantageous for borrowers planning to sell before the IO period ends or those expecting higher income in the future.

  • For Long-Term Stability: P&I loans ensure consistent debt reduction and lower financial risk over time.

Conclusion

Choosing between P&I and IO repayments ultimately depends on your financial goals, cash flow situation, timelines and investment strategy. While P&I loans offer security and long-term savings, IO loans provide flexibility and short-term financial advantages, particularly for investors. Consulting with a finance professional can help tailor a loan structure that aligns with your personal or investment objectives.
