Rents
Reference rents (2025)
| Property type | Median rent (€/m²) | Range (€/m²) |
|---|---|---|
| Flats, all sizes | 12.3 | 10.1 – 14.9 |
| Flats with 1-2 rooms | 15.3 | 12.4 – 18.8 |
| Flats with 3 or more rooms | 10.7 | 8.4 – 13.6 |
| Houses | 11.3 | 8.9 – 14.4 |
How to read this table. This is a predicted advertised rent, including service charges, per square metre per month — not the rent signed in the lease. The range brackets the estimate: most listings in the municipality fall within it. These estimates are recalculated every year with a new model, so two releases cannot be compared with each other.

Energy performance of the housing stock
Breakdown of homes in Île-Molène by energy performance certificate (EPC) band. Since the loi Climat & Résilience (Climate and Resilience Act), it is this band that determines whether a home may be let.

Why this breakdown matters. A dwelling rated G can no longer be let under a new lease since 1st January 2025; F will follow in 2028 and E in 2034. A commune whose stock is largely rated F or G therefore faces a wall of renovation work, or an exit from the rental market.
Note: these figures cover surveyed homes, not the entire stock. A survey is only required on sale or letting, so homes occupied for a long time are under-represented.

Why the number of people per household matters. A household is everyone who shares the same dwelling. The fewer people it has, the more demand shifts towards small homes — studios and one-bedroom flats, sought by people living alone, students and retirees; the more it has, the more demand shifts towards family homes with three or more rooms.
In Île-Molène, a household has 1.64 people on average, compared with 2.17 in France: more people living alone and couples without children, so demand leans more towards small units.

How to read these figures. The standard of living is a household's disposable income (salaries, pensions and benefits, after tax) divided by its number of consumption units: the first adult counts as 1, other people aged 14 or over as 0.5, and each child as 0.3. It allows a single person and a family to be compared.
The poverty rate is the share of residents whose standard of living is below 60% of the national median. INSEE does not publish it for small communes, for reasons of statistical confidentiality: its absence is not a zero.
The unemployment rate here is the census one: people who declare themselves without work and looking for it, among the economically active aged 15 to 64. It is higher than INSEE's quarterly rate, which follows a stricter international definition.

Local taxation
In 2024, the overall property tax rate on built properties is 15.97% in Île-Molène.
| Rate voted by the commune | 15.97% |
|---|---|
| Overall rate on built properties (total) | 15.97% |
| Overall rate on undeveloped land | 2.20% |
Worked example
A dwelling with a cadastral rental value of €3,000 has a tax base of €1,500: the law sets it at half the rental value. In Île-Molène, its property tax (taxe foncière) is €1,500 × 15.97% = €240 a year.
These amounts are before the collection charges retained by the State. Your property's rental value is shown on your property tax (taxe foncière) notice.
| Year | Communal rate | Overall rate on built properties | Household waste |
|---|---|---|---|
| 2021 | 15.97% | 15.97% | — |
| 2022 | 15.97% | 15.97% | — |
| 2023 | 15.97% | 15.97% | — |
| 2024 | 15.97% | 15.97% | — |
The overall rate remained stable between 2021 and 2024.
How to read these rates. Property tax (taxe foncière) is calculated by multiplying the property's tax base by the overall rate: this is the figure to compare between communes, not the communal rate alone. Since 2021, départements no longer collect property tax on buildings; their former share is included in the communal rate.
A high rate does not mean a high tax. The cadastral rental value is not the market rent: it is an administrative estimate based on 1970 rents, revalued each year by a national coefficient. In a town with old, low rental values, a 50% rate can cost less than a 25% rate elsewhere.
Commune subject to the tax on vacant dwellings

Natural and technological risks
The risks identified by the State in the territory of Île-Molène, what they mean, and what they change for a property.
Radon potential
Significant potentiallevel 3 out of 3
Radon is a natural radioactive gas that rises from granitic and volcanic soils and can build up in poorly ventilated rooms, especially on ground floors and in basements.
For a property: At this level, the seller or landlord must inform the buyer or tenant. Good ventilation and a sealed ground floor are usually enough to reduce exposure.
A prevention plan is not a bad sign in itself. It shows that the risk is mapped and regulated; it is its absence for a known hazard that should raise questions.
This page describes the commune, not an address. Before a sale or a letting, the seller or landlord must provide a risk statement drawn up for the property. You can obtain one free of charge for any address at georisques.gouv.fr.
