Reservation agreements are common in Swiss residential transactions, often with a payment of CHF 5'000-20'000. With the Swiss home-ownership rate at about 36% according to the Federal Statistical Office, many buyers encounter these documents only once or twice in their lives.
A reservation agreement usually records that a property will not be actively marketed to other buyers for a defined period, often 10-30 days. It is not a public deed of sale and does not transfer ownership in the land register. If the document already creates an obligation to buy or sell, it may be treated as a preliminary purchase agreement. For Swiss real estate, Article 216 of the Code of Obligations requires public notarisation for such binding commitments.
In practice, reservation payments often range from CHF 5'000 to CHF 20'000, and for some new-build projects they may be around 0.5-1.0% of the intended price. On a CHF 1'200'000 apartment, a CHF 10'000 reservation is below 1% of the price but still material if repayment is disputed. The money may be paid to the seller, the agent or a separate account; a notary escrow account is usually clearer than an ordinary business account. The agreement should state the amount, payment deadline, reservation period and account holder without ambiguity.
If the notarised purchase contract is signed, the reservation payment is usually credited against the purchase price or repaid at completion. If the seller withdraws or a legal defect in the property prevents the sale, full repayment is generally the appropriate result. If the buyer withdraws without a contractual reason, some agreements allow deductions for documentation, credit checks or draft contracts. Rather than allowing the full CHF 20'000 to be forfeited, the contract should set a defined cap such as CHF 1'000-2'000 or require proof of actual costs.
Article 216 of the Swiss Code of Obligations requires public notarisation for real estate purchase contracts and preliminary purchase agreements. A privately signed reservation agreement therefore cannot normally create an enforceable duty to buy or sell a property. Penalty clauses or full forfeiture clauses are particularly vulnerable if they economically secure a purchase obligation that was not notarised. A dispute over CHF 20'000 is below the civil-procedure threshold of CHF 30'000, but legal costs and delay can still outweigh the practical value of the reservation.
Before signing, buyers should review the land-register extract, easements, condominium rules, renovation fund and the minutes of the last 2-3 owners' meetings. Swiss banks apply FINMA and Swiss Bankers Association standards, commonly around 80% maximum loan-to-value, at least 10% genuine equity and amortisation to two thirds within 15 years. Affordability is often stress-tested with an imputed interest rate of about 5%, running costs of roughly 1% of the purchase price and total housing costs not exceeding one third of gross income. Cantonal transaction costs also matter: Zurich has no real estate transfer tax, while cantons such as Vaud or Geneva can charge materially higher duties according to Federal Tax Administration summaries.
Buyers who need genuine legal commitment can use a publicly notarised preliminary purchase agreement instead of a simple reservation. It can define the price, deposit, financing condition, signing date and consequences of withdrawal for a period such as 30-90 days. Notarial practice differs by canton, with official notaries in Zurich and independent notaries in cantons such as Bern, Vaud and Geneva. This route adds cost, but it reduces the risk that CHF 10'000-20'000 remains blocked without a clear legal basis.
