Points to watch before buying or renting

• The property tax rate is well above the median of the municipalities in its département: factor it into the cost of owning the property, on top of running charges.
• Flood risk is listed: check the risk statement for the property and, if there is one, the prevention plan attached to the local urban plan.
• Before buying into a co-ownership: ask for the minutes of the last three general meetings, the maintenance log, the amount of the works fund and the state of unpaid charges.

💶 Prices and rents: how they have changed

4,337 listings observed. These are advertised rents, service charges included: they are higher than the rents of existing leases. The estimation method was revised in 2022: only the 2022 and later editions, which are comparable with each other, are shown. The gross yield compares the annualised rent with the median sale price of flats; it takes no account of service charges, property tax or vacancy.

🌊 Natural hazards

Hazards listed for the municipality:

A declaration recognises a state of natural disaster for a given event; it triggers the “natural disasters” cover of home insurance policies and of the building’s insurance. “Drought” declarations relate to the shrinking and swelling of clay soils, a frequent cause of cracks in buildings. A risk statement (état des risques) must in particular be attached to a sale or lease when the property lies in an area covered by a prevention plan, in seismic zone 2 to 5, or with a class 3 radon potential. This page presents municipal data: it does not replace the risk statement drawn up for the property’s address.

🧾 Property tax and local taxation

The overall rate adds the municipal share and the inter-municipal share. The tax due by an owner equals this rate applied to half of the home’s cadastral rental value, reduced where applicable by exemptions.
