Buying a second home involves a budget that far exceeds the price displayed in the listing. Local taxes, ongoing maintenance, insurance, energy: recurring charges represent a significant fraction of the property’s value each year. Before signing, measuring the gap between the acquisition cost and the ownership cost helps avoid an investment that weighs more than it brings in.
Housing tax and surcharge in tight areas: the most changed item
The housing tax has been abolished on primary residences, but it remains due on second homes. This maintenance creates a direct tax differential between the two types of housing.

Since the finance laws of 2023 and 2024, many tourist or university municipalities classified as tight zones are voting for increases that can reach 60% of the base contribution, under Article 1407 ter of the CGI. The movement is accelerating: new municipalities join the tight zones each year, making the tax amount difficult to predict over five or ten years.
Before estimating the costs and expenses of a second home, checking if the municipality already applies this increase (and at what rate) is a prerequisite. Property tax is added to this, and its amount varies significantly from one community to another.

Recurring charges of a second home: maintenance, insurance, energy
A property occupied for a few weeks a year can sometimes age faster than one that is continuously inhabited. Prolonged absence encourages humidity, undetected infiltrations, and minor damages that worsen without prompt intervention.
Ongoing maintenance and occasional work
Gardening, chimney sweeping, roof inspection, wood treatment: these items recur every year. In an old house, a facade renovation or a replacement of joinery can represent several thousand euros in a single operation.
Second homes are almost systematically excluded from renovation aid such as MaPrimeRénov’. The owner therefore finances the entirety of the work, including those related to energy performance.
Insurance and surveillance
The home insurance for a second residence generally costs more than that for a primary residence. Insurers apply a surcharge related to prolonged vacancy, which increases the risks of unreported damage (water damage, burglary). Some owners add a remote monitoring or caretaking contract, especially in isolated areas.
Energy and subscriptions
Maintaining frost-free heating in winter, paying subscriptions (water, electricity, internet) for intermittent use: the cost/utilization ratio is unfavorable. Here are the recurring charges to budget:
- Housing tax and property tax, recalculated each year by the municipality
- Home insurance with a vacancy surcharge, plus possible remote monitoring
- Maintenance of the building (roof, facade, plumbing) and the land (garden, fences, access)
- Energy and telecom subscriptions maintained all year despite partial occupancy
- Condominium fees if the property is in a collective building
Seasonal rental: potential income, tightened regulatory framework
Renting out your second home for a few weeks a year can offset some of the charges. The calculation seems simple, but the legal framework has tightened considerably in recent years.
Since the Le Meur law, an obligatory registration number must appear on every advertisement for furnished tourist rentals, under penalty of sanctions. In municipalities in tight areas, a change of use authorization may be required, and it is not automatically granted.
Another recent constraint: new furnished tourist rentals must display a DPE rated from A to E. An old second home rated F or G can no longer be rented out seasonally without prior energy renovation work. However, as mentioned above, these works do not benefit from any public aid for a second home.
The tax regime for rental income (micro-BIC or real) determines the portion effectively retained by the owner. The profitability calculation must include regulatory costs (registration, diagnostics, possible works) in addition to the usual management and maintenance charges.
Realistic annual budget: what a second home costs over ten years
Thinking in terms of a single year masks the financial reality of such an investment. Over ten years, recurring items (taxation, maintenance, insurance, energy) accumulate and represent a notable fraction of the initial purchase price.
Two variables amplify the gap between the planned budget and the actual budget:
- The annual revaluation of local tax bases, which drives up property and housing taxes without the owner having any control
- The accelerated aging of the building in the absence of regular occupancy, generating more frequent unexpected repairs than in a primary residence
- The regulatory evolution (surcharges in tight areas, DPE standards for rental), which is impossible to anticipate precisely at the time of purchase
Comparing the total cost of ownership over ten years to the net rental yield (if there is a rental) or to the simple cost of vacation rental allows for a decision. Owning often costs more than renting for a few weeks a year, unless the property appreciates significantly upon resale, after deducting capital gains tax.
The only area where the owner retains some leeway is preventive maintenance: intervening early limits heavy repairs. For the rest, local taxation and the regulatory framework evolve independently of their will.
