A French co-ownership's ordinary budget covers 12 months, but it does not include every bill a building can produce. Service Public's budget guidance, checked on 4 October 2026, separates routine spending from major works financed through specific calls for funds. That distinction matters when someone hands you a ski apartment brochure with an attractive rental percentage.
A yield can be arithmetically correct and still tell you very little about the money you will keep. Before comparing two Alpine purchases, ask what sits above the line, what has been deducted below it, and which costs have disappeared altogether. The answer is usually in the supporting documents, rather than the size of the percentage.
Start with the number underneath the yield
Consider a deliberately fictional apartment costing €400,000 and producing €24,000 in annual accommodation revenue. Divide one by the other and the gross yield is 6%. These are teaching figures, not a DOMOSNO listing, a resort average or a rental forecast. They make a useful starting point precisely because nobody needs to argue about the view.
Now assume the buyer spends another €40,000 on acquisition costs, initial furniture and agreed improvements. That sum is also illustrative; actual costs depend on the transaction. The same receipts divided by the resulting €440,000 total commitment produce roughly 5.45%. No guest has cancelled. Nothing has broken. We have merely changed the denominator to reflect more of the buyer's outlay.
Label both calculations. A yield on the property price can help compare advertisements using the same convention. A yield on total acquisition and setup cost helps you understand the money required to get started. Neither includes borrowing costs, operating expenses or personal taxation. Mixing the two conventions makes the cheaper-looking proposition difficult to trust.
Keep the purchase funding plan separately. An investor borrowing part of the price has a different cash commitment from a cash buyer, but that does not make the apartment itself generate more rent. Returns on invested equity need their own calculation, including the loan.
Ask the manager for a sample owner statement
A management percentage without a definition is half a quotation. Request the proposed contract, its fee schedule and an anonymised owner statement showing how a booking becomes a payment to the owner. Ask which amount attracts commission, whether the quoted fee includes VAT, and how distribution-platform costs enter the calculation.
For example, our fictional €24,000 revenue could incur an assumed management charge of €4,800 if a hypothetical VAT-inclusive fee of 20% applies to that entire amount. This is arithmetic, not a claim that 20% is a normal Alpine tariff. A quotation based on a different revenue figure, or with tax and services added, cannot be compared simply by looking at its headline rate.
Cleaning and linen deserve particular attention. If guests pay these separately, record the receipts and corresponding expenses consistently, or exclude both from accommodation revenue. Do not count a cleaning payment as rental profit and then forget the cleaner. Equally, do not subtract a charge twice because it appears on both the booking statement and the manager's summary.
Check less visible services too: key collection, emergency attendance, consumables, replacement purchases, inspections after owner stays and contractor supervision. Ask who can authorise expenditure and at what limit. A lower commission with numerous additional charges may still suit you, but only when you have priced the services you actually need.
Separate running expenses from future repairs
The French housing information agency ANIL includes management, insurance, repairs, shared-building charges and taxation among the costs to assess in its investment guidance. Its broad message is useful here: rental receipts are the beginning of a budget. Its general rental material is not a personalised tax calculation for a non-resident holiday-home owner.
Build your own property-specific schedule from evidence. Use a manager's written quotation, the seller's actual utility bills, insurance terms and the relevant local tax documents. Identify what each figure covers and which period it concerns. An annual estimate supplied during construction deserves a different label from a settled account for an occupied resale building.
For the fictional apartment, assume €5,000 a year for recurring property expenses outside management, covering shared charges, utilities, insurance and property taxes. The real amount might be very different. Next allocate an illustrative €1,200 to an owner-held replacement reserve. This reserve is a budgeting choice, not a statutory allowance or a statement about tax deductibility.
The distinction helps when a dishwasher fails. Paying for it from a reserve does not make it free; it means you planned the cash. Track both the reserve balance and actual purchases so that the same replacement is not charged twice in your long-term model. Furniture packages should earn their place through durability as well as their photographs.
The building has its own spending timetable
Service Public's explanation of co-ownership charges distinguishes general charges from those associated with collective services and equipment. The allocation rules matter. A flat's floor area alone is not enough to reconstruct every share of the building's bills. Ask for the charges attributable to the exact lots being purchased, including any garage or additional storage.
The ordinary budget prévisionnel is useful evidence for recurring spending. It is not proof that the roof, façade or lift will never require a separate payment. Read the building's works documents alongside its accounts and ask the managing agent to identify approved expenditure, its payment timetable and projects still under discussion.
A further line is the fonds de travaux. Service Public explains the co-ownership works fund separately from routine budgeting. Obtain the actual contribution applicable to the lot and have the notaire explain its treatment in your purchase. Do not substitute a generic internet percentage for the building's current documents.
For comparison purposes, show recurring charges, works-fund contributions and any identified exceptional payments on separate lines. A one-off major payment should be visible in the year it falls due. Spreading it across a holding-period analysis may be useful too, provided you retain the actual cash timetable. The bank account does not pay bills with averages.
Follow the money all the way to cash flow
Return to our fictional example. Accommodation revenue of €24,000, less €4,800 management, €5,000 recurring expenses and the €1,200 reserve allocation, leaves €13,000 before financing, personal taxation and any exceptional building payments. On the €440,000 acquisition-and-setup assumption, that is approximately 2.95%. Call it a budgeted operating surplus after reserve allocation, rather than an undefined net yield.
If assumed annual mortgage payments were €12,000, only €1,000 would remain before those other items. That loan payment is another fictional input, not a rate quotation or lending offer. The calculation illustrates why an apparently profitable rental can leave limited spare cash. Principal repayment reduces debt, but it still leaves the owner's bank account.
Keep taxation outside this simplified illustration until someone qualified has assessed your actual circumstances. Residence, ownership structure, rental arrangements and applicable rules can change the result. An assumed tax benefit should never be inserted merely to make the bottom line positive. Nor should a future sale gain be used to pay next January's invoice.
For a buyer whose household income is in sterling or another currency, retain the operating model in euros and add a separate conversion scenario for transfers. This avoids confusing changes in the apartment's performance with changes in the cost of funding it from abroad.
Stress the expenses as well as the income
A useful downside case changes a small number of clearly named inputs. Reduce the fictional accommodation revenue by 15%, to €20,400, while retaining the assumed 20% management calculation. Keep the €5,000 recurring expenses and €1,200 reserve unchanged. The resulting operating surplus is €10,120, before financing and personal tax.
Under the same hypothetical €12,000 annual loan payments, that produces a €1,880 cash shortfall before the other excluded items. This is not a prediction of falling rental demand. It is a test of how much additional cash the buyer would need if one assumption disappoints. Write down where that money would come from.
Then test an expense shock separately: an identified works payment, a larger insurance quotation or a replacement appliance. Resist combining every imaginable problem into one theatrical disaster. A model is more useful when you can see which input causes the difficulty and decide whether the risk is acceptable.
Owner occupation also has costs. Include the cleaning, utilities and other services arising from your own visits, even if your rental estimate already excludes those dates. The enjoyment of the home can be a sound reason to buy; it simply belongs alongside the financial assessment rather than inside rental revenue.
Compare evidence before comparing percentages
For a resale, request historical owner statements and reconcile their coverage with invoices and the period the apartment was offered to guests. Remove one-off items transparently. For a new build, distinguish developer estimates, independent manager forecasts and contractual commitments. A forecast does not become a trading history because it is printed neatly.
Keep a short evidence note beside each spreadsheet input: supplier, document date, period covered and whether it is confirmed or estimated. Where a figure is missing, leave a visible gap and obtain it before relying on the result. This is particularly helpful when two properties have different heating arrangements, management packages or initial furnishing requirements.
The useful final comparison is modest: total money required at purchase, expected annual operating surplus under stated assumptions, cash remaining after financing, and the additional cash required in a downside case. Those measures help you decide what the home asks of your household. A single percentage cannot carry all that information.
If you are weighing up Alpine properties, talk to DOMOSNO about your shortlist and the documents needed to compare their running costs. A clear budget leaves more room to enjoy the reasons you wanted a place in the mountains.
