Are the free tools really unlimited?

We are in launch phase. All features are open for free to gather feedback from Luxembourg professionals. Pro tier will move to €29/month once the platform stabilizes — early adopters will keep preferential access.

Why create an account if it's already free?

An account lets you save your simulations in the cloud (accessible from any device), export professional PDF reports and customise your profile on generated documents.

Your data is hosted in Europe on secure servers (Supabase). We do not sell or share your information. Without an account, nothing leaves your browser.

When will the Pro tier be available?

Organise evidence, sources, calculations, assumptions and limitations in a working dossier. The professional checks the information, determines the necessary investigations and takes responsibility for their conclusions. Exporting or technically signing the file does not certify professional compliance.

Can the dossier be adapted to different property types?

The module offers several property types and methods. The professional selects suitable ones, adjusts assumptions and documents limitations; selecting a property type does not validate the analysis.

Property tools, energy simulators, management and dossier preparation. Indicative calculations, explicit assumptions and exports to review.

From calculations to professional valuation

The European Valuation Standards (EVS), published by TEGoVA, provide a framework for professional valuation: a defined assignment, reviewed sources, justified methods and explicit assumptions and limitations. This approach makes the analysis more transparent and documented; a formula alone is not an expert valuation.

Tevaxia helps prepare data and explore indicative scenarios. The software does not replace property checks, professional judgement or an expert’s report. It does not certify compliance with EVS or TEGoVA.

In Luxembourg, the Luxembourg Property Valuation Institute (LPVI) is the professional association that is a member of TEGoVA and the national contact point for TEGoVA licences. Contact the association to learn about the process or ask for guidance towards an expert.
