Real Estate Valuation Luxembourg: Precision vs. Marketing
Let's be honest: receiving a 30-page bound folder filled with photos of your own living room won’t help you determine the value of your property. You know your home; you live in it. What you need isn't a photo album, but consistent and justifiable figures.
In Luxembourg, the market is highly competitive, and some agents are tempted to join the "race for the mandate": announcing a flattering price just to secure the contract, only to lower the price a few months later. At BLImmo, our approach is radically different.
Engineer Expertise at the Service of Your Assets
My background as an engineer is the foundation of the agency's working method. Passionate about numbers and precision, I conduct detailed analyses of market data. At BLImmo, we rely on a rigorous analytical structure. It is, in my view, the only solid basis for a real estate valuation.
The Trap of Asking Prices on Portals
Many owners and some agents make the mistake of relying solely on a comparative analysis of prices displayed on real estate portals. This is a biased indicator: in Luxembourg, the average gap between the asking price and the actual selling price is 17%.
Furthermore, this gap is not constant: some agents stay close to reality, while others massively overvalue. Without mastering the "property by property" history, looking at listings does not allow for a fair price. To sell, you must rely on the notary deed price, not the "dream" price.
The Three Pillars of Value and the Importance of Measurement
To define a property's price, three fundamental criteria dictate the market: location, surface area, and standing. However, the number of square meters is often a source of interpretation. Ultimately, what a buyer pays for are the square meters. It is therefore essential to carry out a precise measurement on-site.
The calculation method at BLImmo clearly distinguishes the living area (primary market value) from useful and annex surfaces (basements, garages, terraces).
Why the "Fair Price" is Your Best Strategy
An overpriced property ends up "burning" on real estate portals, leading to much more aggressive negotiations. Moreover, since April 2023, Luxembourgish banks have been required to independently assess property values. If the amount on the sales agreement (compromis) is disconnected from reality, the bank will block the buyer's credit. A fanciful valuation is therefore not just a deterrent for viewings; it is a direct obstacle to the financing of your sale.
Factual Analysis Over Glossy Paper
The analysis at BLImmo is based on the intersection of three methods via a rigorous spreadsheet:
- Value per m² (Price/m² and Depreciation): A precise calculation based on the year of construction, renovations carried out, the Energy Performance Certificate (CPE), and the technical condition of each element (roof, heating, etc.).
- Price Evolution: A comparative analysis between your initial purchase price and the current market reality.
- Rental Yield: Validation of the sale price through potential rent, a crucial data point for investors.
Transparency as a Guarantee of Results
Over the last two years, the rigor of this engineering method has paid off:
- Precision: Our valuations show an average gap of only 5% compared to the final price recorded at the notary.
- Reliability: More than 90% of the sales agreements signed at BLImmo actually lead to a final sale at the notary.
