How to analyze a property in Belgium: 7 essential criteria
Buying a property is the most important financial decision of your life. Here are the 7 criteria that a real estate expert analyzes systematically — and that Ask John automates for you.
1Price per m² compared to market
Compare the asking price per m² with Statbel data for the municipality. A property at €2,800/m² in a municipality where the median is €2,200/m² is 27% above market — that's a red flag. Conversely, a property 10-15% below market may indicate a bargain or a hidden defect.
2EPC certificate (Energy Performance)
In Belgium, the EPC (or PEB in Wallonia) is mandatory for any sale. An EPC A or B means good insulation and low energy bills. An EPC E, F or G implies significant insulation work (€15,000-40,000 depending on size). In Flanders, a minimum EPC will soon be mandatory, which directly impacts resale value.
3Realistic renovation budget
A property "to be renovated" often hides underestimated costs. Most expensive items: roof (€15-25K), facade and insulation (€20-40K), kitchen and bathroom (€10-20K each), heating (€8-15K). Always get quotes before signing the compromise and add 15-20% buffer for unforeseen expenses.
4Neighborhood quality and environment
Check for noise pollution (Zaventem or Charleroi flight corridor), proximity to public transport, schools, shops and green spaces. Also consult the sector plan to see if any construction or infrastructure projects are planned nearby.
5Complete financial feasibility
Beyond the purchase price, calculate total cost: registration fees (3-12.5% depending on region), notary fees (~1.5%), mortgage fees (~1%), renovation, and moving. Rule of thumb: budget 15% of purchase price for ancillary costs and ensure the monthly payment does not exceed 33% of your net income.
6Capital gains potential
Municipalities well-served by transport and in development (new projects, schools, shops) offer the best potential. Check Statbel price evolution over 5 years for the municipality and compare with neighboring municipalities. Properties with good EPC ratings resell more easily.
7Hidden risks to verify
Before signing, verify: flood risk (flood zone maps), presence of asbestos (pre-1997 buildings), electrical safety (mandatory certification in Flanders), easements and cadastral map, soil condition (BOFAS certification), and for apartments, the financial health of the condominium (reserve fund, ongoing lawsuits).
