Why Invest in a Second Property for Rental?

The popularity of buying a second property for rental purposes has increased significantly in recent years. One of the main reasons is that traditional savings accounts currently generate very low returns due to low interest rates, while real estate offers attractive opportunities both in the short and long term.

Buying a second property allows you to generate passive rental income, and with rising real estate prices in Belgium and across the BENELUX, your property may also increase in value over time.

The Costs of Owning a Second Property

As with your primary residence, owning a second property involves several fixed and variable costs. In addition to mortgage payments, you need to consider maintenance, insurance and taxes.

As a landlord, you are responsible for ensuring the property complies with regulations and remains in good condition. During the rental period, damage may occur, and depending on the situation, responsibility may lie with either the landlord or the tenant. It is therefore advisable to set aside a financial reserve for repairs and renovations.

In Flanders, registration duties for a second property are typically around 12%, compared to 2% for a primary residence. In Brussels and Wallonia, they can reach 12.5%. While this increases the initial investment, it also reflects the long-term value potential of real estate.

At TREVI Rental Management, we take care of these responsibilities for you. Our full-service approach covers everything from finding reliable tenants to ensuring proper property maintenance, allowing you to focus on your investment strategy.

Tax Considerations in Belgium

In Belgium, rental income is not always taxed based on actual rent received. For a second property that is used privately or rented to a tenant for private use, you must declare the cadastral income in your tax return.

The tax authorities index this cadastral income and increase it by 40%. The adjusted amount is then added to your taxable income and taxed according to applicable income brackets, which can reach up to 50%, depending on your total income.

With TREVI, you benefit from expert guidance through the legal and fiscal aspects of rental property. Our specialists ensure full compliance, giving you peace of mind.

What Are the Risks of Real Estate Investment?

While buying a second property can be a strong long-term investment, it is not without risks. The rental market can fluctuate, making it more challenging to find tenants. However, in the current market, there is a shortage of rental housing in Belgium, with an average of 30 to 35 potential tenants per property.

Unexpected costs such as maintenance or renovation may arise. Poorly maintained properties can result in lower rental income or even vacancy. It is also important to remember that property values are not guaranteed to rise. Local market conditions and economic changes can influence your return.

In Summary

Buying a second property to rent out can be an excellent way to generate passive income and grow your wealth. However, it requires careful planning around financing, taxation and ongoing costs. Understanding your obligations and potential risks is essential to making a successful investment.
