Long-term or seasonal rental: which model?

Yannick Akoka, co-founder of AIIA Published on 1 October 2026 · 5 min read

Long-term rental or furnished tourist rental: two statuses, two sets of regulations. A decision grid for choosing your operating model.

Once the five viability criteria of a rental project have been set (see our method for assessing profitability), one question remains to be settled separately: should your modular home be geared towards long-term rental or seasonal rental? The two models differ not only in their income potential, which we never quantify in advance as it depends so much on each project, but in two different legal statuses, with obligations and a management pace that are in no way comparable. This article offers a strictly comparative decision grid, to be used once the five profitability criteria have already been set.

Understanding the subject

Long-term rental places the property under a standard residential lease: an unfurnished tenancy agreement, with a minimum term of three years, or a furnished tenancy agreement, with a minimum term of one year (nine months for a student lease). The tenant makes it their residence, rents are capped in so-called high-pressure areas, and the contractual relationship follows formal rules on notice and termination. Seasonal rental follows a different logic: it is aimed at short-stay occupants, who do not establish their residence there, for occasional stays by the day, the week or the month. According to the French Ministry of the Economy, this arrangement cannot exceed 90 consecutive days with the same guest, and the rent is set freely by the owner, in exchange for heavier contractual and declaration formalities.

To decide between the two, the location of the land remains the starting point, but the question to ask differs from the one posed by the general method: it is no longer a matter of assessing whether the location is favourable to renting, but which of the two models it favours. A plot close to an employment area, a university hub or a regular transport route naturally points towards long-term rental, where demand remains stable all year round. A plot located in an area with high seasonal tourist traffic, with no nearby employment area, points instead towards seasonal rental, where demand is concentrated in certain periods. The same plot does not always justify both models at once.

Going further

The formalities to complete are not of the same order depending on the model chosen. For a long-term rental, according to the French Ministry of the Economy, the landlord must register via the single business formalities portal within 15 days of the start of the rental activity. For a seasonal rental classified as a furnished tourist rental, a written contract stating the price and the condition of the property is required, and a declaration to the town hall is necessary: registration in municipalities that require it, a simple declaration elsewhere. Since 21 November 2024, co-ownership regulations must also explicitly authorise or prohibit furnished tourist rentals, a point to check before any project in a co-owned building.

Local regulations weigh differently on the two models. In high-pressure areas, long-term rental may be subject to rent controls. Seasonal rental, for its part, is regulated municipality by municipality: some towns limit the number of nights authorised for a second home or impose stricter registration. The tax regime also differs between the two models: property income for an unfurnished rental, industrial and commercial profits (BIC) for a furnished rental, whether long-term or seasonal, with thresholds that change from one year to the next. We give no tax or legal advice here: these points must be checked with the town hall where the home will be sited and with an accounting or legal professional before any decision.

Practical advice

In summary, three questions help narrow down the choice. Is the plot close to a stable employment area or to an area with high seasonal tourist traffic? Is the project owner prepared to take on active management, with a frequent turnover of occupants, or do they prefer a more stable rental relationship over several years? And does the municipality where the home will be sited impose particular constraints, rent controls on one side, a cap on nights or stricter declaration on the other? None of these questions has a universal answer: each must be checked for the plot and the project concerned, relying on the five-criteria method to then quantify the viability of the chosen model.

This comparison does not replace a feasibility study specific to each project. Our Invest section outlines the two models and offers an initial simulation tool for guidance only, and our configurator lets you move forward in concrete terms once the operating model has been chosen.
