Property leverage: how it multiplies your returns (and your risks)

Leverage is the concept that makes property one of the most powerful investment vehicles for the private investor. And it's also what makes it dangerous if it's used badly. Understanding it properly is probably the most important lesson a beginner property investor can learn.

What leverage is, in simple terms

Leverage means using borrowed money to invest. In property, the mortgage is your leverage instrument. When you buy a property with 20% of your own capital and an 80% mortgage, you are leveraged 5 times over: you control a €100,000 asset with only €20,000 of your own.

How it multiplies your returns: a concrete example

Suppose you buy a flat for €100,000 with €20,000 of your own money and an €80,000 mortgage. After 5 years, the property has gone up in value by 20% and is worth €120,000. You've made €20,000. But your initial investment was €20,000... which is equivalent to a 100% return on your own capital. Without leverage, investing the €100,000 directly, you would have made only 20%.

On top of this comes the cash flow from the rent over those 5 years, which covers the mortgage repayment and generates a surplus. The total return can be very significant.

How it magnifies losses

The effect works in exactly the same way in reverse. If the property falls by 20% and is worth €80,000, your €20,000 of equity has disappeared completely (the bank is still owed its €80,000 of debt). And if you have to sell at that point, you owe the bank more than you get for the property: the situation known as "negative equity".

How much leverage is reasonable

The prudent investor's rule: the cash flow from the rent has to cover the mortgage repayment even at 80% occupancy (not 100%, which is unrealistic). If the numbers don't add up with that safety margin, the leverage is excessive for that asset or that purchase price. Leverage is a powerful tool, but the safety margin is what makes the difference between the investor who survives the cycles and the one who doesn't.
