Understanding Real Estate Returns: How to Calculate and Maximise Your Investment
Blog
23/10/2025
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
Rental yield reflects the relationship between rental income and the total acquisition cost of a property.
For existing properties:
gross yield ranges between 2.8% and 3.2%
net yield ranges between 2.6% and 3%
For new developments:
gross yield typically ranges between 2.6% and 3%
net yield is between 2.4% and 2.9%
The total acquisition cost includes not only the purchase price, but also additional expenses such as:
taxes
notary fees
renovation costs (especially for energy efficiency upgrades)
Once the lease agreement is signed, you can delegate the financial management to a professional property manager such as TREVI. We take care of rent collection, follow-up in case of non-payment, and all technical management tasks, from handling issues to coordinating maintenance and repairs.
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.
for new properties, it typically takes 5 to 7 years to recover costs
for existing properties, approximately 4 years
To maximise potential capital gains, it is essential to:
purchase at the right price
choose a strong and attractive location
Key factors include:
good accessibility (public transport and road connections)
proximity to green areas
expected population growth
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.

Net Rental Yield
Net yield takes into account additional costs such as:
maintenance
