Leverage effect
A mechanism by which an investor uses bank financing to acquire a property whose yield (rents) exceeds the cost of borrowing (interest), thereby amplifying the return on their own capital. The higher the loan proportion, the stronger the leverage. The effect reverses if interest rates exceed the rental yield, deepening negative cash flow. It is a key concept in buy-to-let investment advisory.
Key points
- Leverage is positive when the gross rental yield exceeds the loan interest rate.
- The higher the loan proportion, the more leverage amplifies the return on equity.
- It reverses (negative leverage) if interest rates exceed the rental yield.
- It is a central indicator in buy-to-let investment advisory.
Frequently asked questions
How does leverage work on a buy-to-let investment in practice?
The investor borrows most of the purchase price. Rents received repay the instalments, and if the rental yield exceeds the cost of borrowing the surplus accumulates. At resale, the capital gain is on the full property value while the equity invested was small: the return on equity is therefore much higher than for a cash purchase.
When does leverage turn negative and what are the risks?
If interest rates rise above the rental yield, each euro borrowed costs more than it generates. The investor must then cover the cash shortfall from their own pocket each month. Combined with prolonged rental vacancy, the financial pressure can become unsustainable. The broker must present this adverse scenario during the yield analysis.
What is the difference between leverage effect and gross rental yield?
Gross rental yield measures the property's performance relative to its purchase price (rents / price). Leverage measures the impact of financing on the return on invested equity: it compares the property yield to the cost of debt. A 5% yield with a 3% loan produces positive leverage; the same yield with a 6% loan produces negative leverage.
In practice
An investor buys a property at €200,000 with €40,000 down (20%) and borrows €160,000 at 3.50%. The gross rental yield is 5.5%. The positive gap of 2% (5.5% - 3.5%) amplifies the return on their €40,000 equity well beyond the rental yield alone.
