Two guests staying for three nights produce six tourist nights or nuitées, in INSEE’s statistics. They do not produce six nights of rent for an apartment owner. That small distinction, explained in INSEE’s tourism definitions, is a useful place to start before accepting a rental forecast for a French Alps property.
A busy resort can be an excellent place to own a second home. It does not follow that every apartment there earns the same income, or that a handsome occupancy percentage will pay the bills. The useful questions are surprisingly ordinary: which nights were available, which actually sold, what the owner received, and where your own holidays fit.
This is a method for reading a letting proposal, checked against official statistical sources on 27 September 2026. The worked calendar below is deliberately hypothetical, not a forecast for any resort or property. No nightly prices or investment returns are assumed.
Start with the thing being counted
Tourism reports can count people, stays, guest nights, occupied rooms or occupied accommodation units. These measures answer different questions. A family filling an apartment for a week contributes more guest nights than a couple taking the same apartment for the same week. The apartment has still been let for one week.
For your own rental appraisal, ask for booked apartment nights and realised accommodation income. Keep the guest count separately. It may help explain wear, linen requirements or the appeal of different sleeping arrangements, but multiplying it by the calendar will not create extra nights to sell.
The distinction also matters when someone quotes platform data. INSEE’s discussion of short-term letting platforms explicitly uses person-nights when presenting tourism volume. A large destination total is evidence of activity within that dataset. It cannot be divided casually by the number of advertised apartments to obtain an individual owner’s expected bookings.
Before discussing performance, write the unit of measurement beside each number. It sounds pedantic until two apparently conflicting reports become perfectly compatible. One describes people sleeping in the resort; the other describes units sold by a particular operator.
Ask what disappeared from the calendar
INSEE defines occupancy against accommodation offered by establishments that are open. It distinguishes this from utilisation measured against total capacity, including establishments that are closed. For a privately owned ski apartment, the practical lesson is to ask exactly which nights sit below the line in the calculation.
Consider an illustrative winter window of 120 nights. An owner reserves 14 nights for personal use and the apartment is unavailable for another six while work is carried out. That leaves 100 nights offered for rent. If guests book 70 of them, the result is 70% of offered nights, but only 58.3% of the full window. Both calculations are correct. They describe different things.
Those figures are arithmetic, not Alpine market benchmarks. Their purpose is to expose the denominator. An impressive percentage may reflect a very restricted sales calendar. Conversely, an owner deliberately using the property extensively might accept lower calendar utilisation without regarding the purchase as a failure.
Request a calendar that distinguishes paying guests, personal stays, maintenance closures and unsold availability. Ask how cancellations and complimentary stays are treated. A coloured booking screen is useful evidence only when you know what the colours mean; a blocked date is not automatically a paid booking.
Give your own holidays their proper place
The temptation is to obtain an annual letting estimate and then pencil in Christmas, a school-holiday week and several weekends. That reverses the sensible order. Start with the stays you actually want, then ask the manager to price and assess the remaining calendar.
In our example, the owner’s 14 nights are simply two weeks. Their effect on income depends on their dates and the bookings that could realistically have been secured. Removing two weeks does not necessarily reduce potential receipts by the same proportion as it reduces available nights. Nor should every personal stay be valued at the most optimistic advertised tariff.
Ask for comparable achieved bookings around those dates, including the discounts and cancellation outcomes. The right opportunity-cost estimate reflects plausible displaced income and costs avoided. It is a decision aid, not an invoice you owe yourself for enjoying the home.
Non-resident buyers should also test how early personal stays must be reserved under the proposed management arrangement. A calendar that works for a family planning a year ahead may be awkward for someone who visits when work permits. Get the booking rules in writing alongside the fees. Your own access deserves the same attention as the projected income.
Use resort statistics at the right scale
Official tourism evidence helps establish context. In its April 2025 winter release, INSEE recorded 18.4 million guest nights in the Alpine massif for December 2024 to March 2025 in hotels and other collective tourist accommodation, excluding campsites. Those provisional figures were a historical season snapshot, not a September 2026 forecast or an estimate for privately let ski apartments.
The geography matters as much as the date. An Alpine massif total cannot tell you how one building performs. Neither can a commune average fully describe the difference between a convenient pedestrian address and an apartment whose guests must solve transport at the start and end of every ski day.
Use broad figures to frame questions for local operators. Which guest groups are they actually booking? Does the sample include apartments similar in size, condition and location? Are the results drawn from properties available throughout the season, or from owners who released only selected weeks?
Supply deserves a separate check. INSEE’s 2026 commune accommodation-capacity files describe hotels, campsites and other collective accommodation. They are useful for understanding those categories of local supply, but they are not a complete live inventory of every private apartment competing with yours. Ask the manager what has entered their own comparable rental pool and how they selected the properties behind the forecast.
Follow the money past the booking headline
An accommodation booking value and an owner payout are different numbers. Ask for a bridge between them, using the proposed contract and anonymised settlement statements where available. Identify who charges the guest, who collects the money, which deductions occur before payment, and which bills arrive separately.
Do not fill the gaps with a generic management percentage. Establish the actual commission base, treatment of cleaning and linen, distribution charges, cancellation refunds and any minimum fees. If a guest-facing cleaning charge appears as a receipt, show its corresponding expense too. Otherwise a busy changeover schedule can make turnover look healthier without improving the owner’s result.
Then add the ownership costs supported by the property’s documents and current quotations. Separate recurring running costs from occasional replacements and building expenditure. Keep financing and the buyer’s tax position visible in their own calculation, so an operating result is not mistaken for spendable cash after every obligation.
For a buyer whose income is in sterling, prepare the operating account in euros first. Apply the intended exchange-rate assumptions afterwards and show how a less favourable conversion would affect household funding. Do not let a convenient currency assumption disguise a rental shortfall. This is budgeting discipline; a personal tax or finance assessment still needs the relevant professional advice.
Give new builds and resales different evidence tests
A resale may have a letting history, but request the underlying dates, settlements and owner-use pattern. Check that the history belongs to the apartment being sold and that the proposed future arrangement is comparable. A successful previous owner might have managed bookings personally or offered different dates from those you intend to release.
A new apartment cannot provide its own completed rental season before it exists. Its forecast should identify the comparable properties and the adjustments being made for location, layout, finish, facilities and launch timing. A development’s asking price is not evidence of achieved rent, just as a resale’s historic turnover is not a promise of your future income.
Keep the first operating period separate from a mature annual estimate. An apartment becoming ready part-way through a season has a different sales window from one already furnished, photographed and available for advance bookings. Ask who is responsible for each of those steps and when the calendar can genuinely open.
When comparing current French Alps new-build properties with resales, use consistent cost boundaries and your actual personal-use dates. Otherwise the spreadsheet may reward whichever proposal omitted the most expenses. That is an accounting contest, not a property comparison.
Ask for a forecast you can take apart
A useful proposal should allow you to trace its annual total back to periods of the year, available nights, expected paid nights and supported achieved-rate assumptions. Request three calendar versions: the operator’s central case, your intended personal-use case, and a downside case with fewer paid nights or weaker achieved rates.
These are scenarios, not probabilities. Ask the operator to explain each assumption with comparable evidence, and keep uncertain items visible instead of replacing them with reassuring precision. If the purchase only works when every uncertain input goes well, that tells you something important before you commit.
Finally, decide what success means for your household. A second home partly supported by rentals and a property expected to maximise rental income have different calendars. Neither objective needs an inflated occupancy figure. The sounder purchase is the one whose use, evidence and ongoing cash requirements you understand.
If you are comparing Alpine homes, talk to DOMOSNO about your preferred dates, property budget and rental intentions. Bringing those three things together early makes the shortlist more useful and the subsequent questions much sharper.
