How to Prove Your Rental Reliability in Belgium in 2024

Finding accommodation in Belgium has never been more competitive. On average, 34 applicants are competing for a single rental property, and landlords receive piles of applications, some of which are unfortunately falsified. Faced with this reality, how can you stand out? How do you convince a landlord that you are the ideal tenant—reliable and trustworthy? The answer comes down to two words: concrete proof.

In this comprehensive guide, we explain how to build a solid rental application, which documents to present, and how new technologies can give you a decisive edge.

Why rental reliability has become a crucial issue in Belgium

The Belgian rental situation is under pressure. Document fraud is on the rise (10% of falsified applications in France, +40% in one year), which is pushing landlords towards systematic mistrust. At the same time, rental market tension remains very high, making landlords even more selective.

The result: even honest and financially stable applicants struggle to convince. A standard application—payslips, employment contract, bank statements—is no longer enough. Landlords are looking for verifiable guarantees, not documents that can easily be modified with editing software.

Proving your rental reliability therefore means going beyond the usual supporting documents to offer total and indisputable transparency.

The essential documents of a complete rental application

Before discussing innovative tools, let's review the basics. A solid rental application in Belgium generally includes:

A valid ID document (Belgian identity card or passport)
The last three payslips or equivalent proof of income
An employment contract (permanent contract preferred, or clear explanation for self-employed individuals)
The last three bank statements showing regular income
An employer's attestation confirming your professional situation
References from your previous landlord if available
A personalised cover letter for the property in question

These documents remain the foundation of any application. But here's the problem: they can all be falsified. A vigilant landlord knows this. That's why more and more Belgian landlords are turning to automated verification solutions.

How new technologies are revolutionising proof of reliability

Open Banking, a technology that allows real banking data to be analysed with your consent, is profoundly changing the game. Instead of providing bank statements that you printed yourself (and which could be modified), you authorise a direct and secure analysis of your transactions from your bank.

This makes it possible to calculate a rental reliability score based on real data: solely rent payment behaviour—whether they paid their rent on the scheduled date. These indicators give the landlord a much more accurate and authentic picture of your profile.

This is exactly what Immotecto offers with its Tecto Score: a rental reliability score (0 to 110, also presented in descriptive labels), at €0 for you today, calculated solely on your rent payment behaviour via Open Banking. No manipulation possible. No subjective interpretation. Just real figures, presented in a readable format.

Tecto Score and TectoPass: your best allies to convince a landlord

The Tecto Score: at €0 and instant

By registering on immotecto.com, you obtain your Tecto Score in just a few minutes. This score between 0 and 110 objectively summarises your rental reliability. You can share it directly with a landlord via the Immotecto platform, who can then verify its authenticity in real time.

The advantage? It's impossible to falsify. The score is automatically calculated from your banking data. No copy-paste, no possibility of editing.

TectoPass: the certified proof you can take anywhere

To go even further, particularly for situations outside the platform, Immotecto offers TectoPass. This is a certified PDF document, at €0 for you today, which summarises your rental reliability profile and includes a scannable QR code.

Concretely, the landlord simply scans the QR code with their smartphone and instantly accesses confirmation that the document is authentic and has not been modified. TectoPass works even without an Immotecto account on the landlord's side, ideal for non-tech-savvy private landlords.

Why is this a major competitive advantage?

You demonstrate total transparency from the first contact
You immediately reassure a mistrustful landlord
You stand out among the 34 applicants on average for the same property
You accelerate the decision-making process in your favour

Mistakes to avoid in your rental application

Even with the best tools, certain mistakes can ruin your chances. Here's what you must absolutely avoid:

Providing incomplete documents: a partial application is perceived as a warning signal. Anticipate every request.
Omitting negative information: a landlord who discovers an inconsistency afterwards will immediately lose confidence. It's better to explain a difficult situation frankly.
Sending a generic application: personalise your cover letter for each property. Landlords notice this.
Neglecting presentation: a well-organised, readable and neat application reflects your seriousness. Use a single, structured PDF.
Waiting to be asked: in Belgium, speed is often decisive. Send your complete application from the first contact, ideally with your TectoPass included.

Practical tips to maximise your chances

Beyond documents, here are some concrete strategies to strengthen your application:

Offer a solid rental deposit: in Belgium, two or three months' rent as a deposit is common. If you can go beyond that, mention it.
Provide verifiable references: a former landlord who answers the phone is worth their weight in gold.
Show your professional stability: if you're self-employed, provide your financial statements for the last two years and, if possible, client attestations.
Be responsive and professional: respond quickly to requests, be punctual for viewings, and make a good personal impression.
Use technology to your advantage: include your Tecto Score or your TectoPass from the first submission. It's a strong signal that you have nothing to hide.

Conclusion: transparency is your best asset

In a rental market as tight as Belgium's, proving your rental reliability is no longer an option—it's a necessity. Landlords receive dozens of applications, many of which are falsified. To stand out, transparency and verifiability are your best cards.

Building a complete application remains the foundation. But going further with tools like the Tecto Score (at €0) or Immotecto's certified TectoPass immediately places you in a separate category: that of applicants who have nothing to hide and everything to show.
