There are three main types of returns in real estate: rental yield, financial return through leverage, and capital gains upon resale. The total return varies depending on the type of property, its condition, and its location.

For existing houses and apartments, total returns typically range between 3.6% and 4.8%, while for new developments they range between 3.5% and 5%. Investing in garages can yield around 4%, while student housing may generate returns exceeding 4.5%.

Rental Yield

Financial Return (Leverage Effect)

Using financing can increase your overall return, provided that the rental yield exceeds the interest rate of the loan.

In periods of high inflation, borrowing can be particularly advantageous, as the real value of the borrowed capital decreases over time.

Capital Gains on Resale

At some point, you may decide to sell your property. Capital gain occurs when the selling price exceeds the total investment.

To maximise potential capital gains, it is essential to:

Key factors include:

It is generally recommended to hold a property for at least 7 to 8 years, as capital gains can be relatively limited in the first years due to acquisition costs.

In Belgium, if a property is sold within five years of purchase at a profit, a capital gains tax of 16.5% (plus local taxes) may apply.

How to Calculate Your Return

Real estate returns vary depending on the type, location, and condition of the property. While attractive returns are sometimes promoted, it is important to adopt a realistic and critical approach.
