When borrowing from a financial institution for real estate investment, various indicators are examined during the screening process. Among these, the debt service coverage period is a particularly important metric. Understanding this concept correctly can improve your chances of obtaining financing and help you build a more stable investment plan.

What Is the Debt Service Coverage Period?

The debt service coverage period is an indicator that shows how many years it would take to fully repay a loan based on current cash flow. It is a core figure that financial institutions use to assess repayment capacity — if it is too long, the borrower may be deemed unable to repay, resulting in a rejected application.

Formula for the Debt Service Coverage Period

Debt Service Coverage Period = Outstanding Loan Balance ÷ (After-tax Profit + Depreciation)

Properties with higher outstanding balances or lower profitability tend to result in a longer coverage period.

What Is the Ideal Debt Service Coverage Period?

Generally, 20 years or less is considered ideal. In real estate investment, repayment periods of 10 to 35 years are not uncommon, but because real estate is a capital-intensive industry with a high proportion of fixed assets, staying within 20 years broadens your financing options. Some financial institutions may allow up to 25 years, but this significantly limits your choices.

How to Improve the Debt Service Coverage Period

Reduce the Outstanding Loan Balance

Early repayment or switching to a principal-equal repayment schedule can reduce the balance more quickly. Since early repayment may affect other indicators, it is important to make this decision after conducting a comprehensive profitability simulation.

Increase Ordinary Profit + Depreciation

By maximizing profits, optimizing expenses, and actively incorporating factors that can revise valuations upward, you can increase the denominator and shorten the debt service coverage period.

Key Points to Watch Out for in Loan Screening

Excessive Tax Reduction Can Backfire

Aggressively reducing tax measures that compress book profits will decrease after-tax profit and lengthen the debt service coverage period. A balanced tax reduction strategy is essential for achieving both loan eligibility and tax efficiency.

Be Aware of the Useful Life of Older Properties

Older properties have shorter remaining useful lives and are considered to carry higher risks of future rebuilding or major renovation. This can be a factor that worsens the debt service coverage period.

Ongoing Monitoring Is Necessary

Even after securing a loan, regularly calculating the debt service coverage period and identifying the causes of any deterioration early leads to more stable real estate management.

Frequently Asked Questions (FAQ)

Q. Can I still obtain financing if my debt service coverage period exceeds 20 years?
A. Some financial institutions allow up to 25 years, but your options will be limited. It is recommended to take steps to improve the figure and consult with multiple financial institutions.
Q. Will increasing my equity ratio help improve it?
A. Yes, since it reduces the outstanding loan balance. However, you should also consider the balance with your equity yield.
Q. How is it calculated when owning multiple properties?
A. It is typically calculated on a combined basis across all properties. Improving overall portfolio cash flow is necessary.
Q. Why is depreciation added to the denominator?
A. Because depreciation is a non-cash expense that does not involve an actual outflow of funds, it is added to the indicator to reflect true repayment capacity.
