« The best deals are made at auction. » — In the Swiss property market, this phrase is both true and misleading. Yes, it is possible to buy a property 20–30% below market price. But property auctions also carry specific risks that you need to understand before raising your hand.

Whether you are a buyer hunting for a bargain or a seller facing a forced sale, this guide explains the entire property auction process in Switzerland.

In this article: the types of auctions, the step-by-step procedure, advantages and risks, financing, legal aspects, and strategies for bidding successfully.

1. Types of property auctions in Switzerland

There are two main categories of property auction in Switzerland:

Forced auction (debt enforcement)

Organised by the debt enforcement office (bankruptcy office) as part of a foreclosure. The owner is in default and the creditor requests the sale of the property to recover the debt. This is the most common form of property auction in Switzerland.

Voluntary auction

Organised by a notary or an auction house at the owner's request. The seller chooses this method to sell quickly, without negotiation, or to dispose of a property that is difficult to sell on the traditional market.

Judicial auction (partition sale)

Organised as part of an inheritance partition or the liquidation of a marital community (divorce). The court orders the sale when co-owners cannot agree.

2. How a property auction works

The Swiss property auction process follows clearly defined steps:

Step 1: Publication of the sale notice

The sale notice is published in the Swiss Official Gazette (formerly FOSC) and in local newspapers. It contains: the property description, reserve price, auction date and location, sale conditions, and the required deposit amount.

Step 2: Review of the sale file

The sale file is available at the debt enforcement office or from the notary. It contains: the land register extract, charges (mortgages, easements), the property valuation, and the sale conditions. It is strongly recommended to review this file before bidding.

Step 3: Deposit payment

To participate, you must pay a deposit (usually 10% of the reserve price). It is refunded if you do not win the auction. It is forfeited if you are the successful bidder and do not pay.

Step 4: The public auction

The auction takes place in a public session. The auctioneer or notary announces the starting price. Bids rise in increments (usually CHF 5,000 to CHF 20,000). The property is awarded to the highest bidder.

Step 5: Award

Once awarded, the successful bidder must sign an auction award record. Ownership transfer becomes effective after payment of the price and registration in the land register.

Step 6: Payment of the price

The price must be paid within a set deadline (usually 30 to 60 days). Payment can be made in cash, by bank transfer, or by mortgage.

💡 Deadlines: Between publication of the notice and the auction, 2 to 3 months usually elapse. Use this time to prepare your financing and study the file.

4. Financing and deposit

The deposit

To participate in an auction, you must pay a deposit. It is usually set at 10% of the reserve price. It can be paid in cash, by banker's cheque, or by bank guarantee.

The deposit is refunded:

Financing the purchase price

Unlike a classic sale, you cannot make your bid conditional on obtaining finance. You must have your financing in place before the auction.

Financing tips:

⚠️ Warning: If you are the successful bidder and cannot pay, you lose your deposit and the property may be re-auctioned at your expense. The difference between your award price and the resale price may be claimed from you.

5. Reserve price and valuation

The reserve price

The reserve price is the minimum price below which the property cannot be sold. It is set by the creditor (forced sale) or the seller (voluntary sale). It generally corresponds to 80–90% of the estimated value.

Property valuation

Before the sale, the property is given an official valuation by an expert. This valuation is available in the sale file and gives you a basis for setting your maximum bid.

Gaps between valuation and award price

SituationValuation / award gapFrequency
Highly sought-after property (rare location)+5 to +20%⭐⭐
Standard property, good condition-5 to -10%⭐⭐⭐⭐
Property requiring renovation-10 to -25%⭐⭐⭐
Property with occupants (tenants)-15 to -30%⭐⭐⭐
Property with known hidden defects-20 to -40%⭐⭐

6. Legal aspects

Overbidding

In some Swiss cantons, a third party may overbid within 10 days following the award. The overbid must be at least 10% above the award price. If accepted, the first successful bidder is deprived of the property but recovers the deposit.

Unremoved charges

Certain mortgages or easements may remain after the sale. The sale file specifies which charges are cancelled (extinguished by the sale) and which remain. Check this point before bidding.

Tenant's right of pre-emption

In cantons where it applies (Geneva, Vaud, Valais, etc.), the tenant may exercise a right of pre-emption even in an auction. They can then step in as the buyer instead of the successful bidder.

Extinguishment of mortgages

The auction extinguishes the previous owner's mortgages. The sale proceeds are distributed to creditors according to their rank. The successful bidder receives the property free of the seller's debts.

📋 Legal tip: Always have the sale file checked by a notary or lawyer before bidding. Consultation fees (CHF 500–1,500) are negligible compared to the risks of a bad purchase.

7. Strategies for successful bidding

1. Set your maximum bid in advance

Before the auction, determine the maximum price you are willing to pay. Consider: the valuation, necessary renovation work, acquisition costs (3–5%), and your budget. Do not exceed this amount, even in the heat of the auction.

2. Attend several auctions before bidding

Nothing replaces experience. Attend 2–3 auctions as an observer to understand the pace, bid increments, and the behaviour of other bidders.

3. Study the file in detail

Review the complete sale file: land register extract, valuation, sale conditions, charges. Check easements, rights of way, and building restrictions.

4. Prepare your financing

Obtain a mortgage pre-approval before the auction. Allow a margin of 20% above your target price to handle unexpected competition.

5. Bid with confidence

Bid clearly and visibly. Show no hesitation. Experienced bidders know that confidence deters competition.

6. Know the bid increment

Increments are usually CHF 5,000 to CHF 20,000. Bid only the minimum increment to save money. Avoid unnecessary aggressive jumps.

7. Know when to stop

The golden rule of auctions: set your limit and stick to it. There will always be other properties. Do not let emotion take over.

8. Voluntary vs. forced auctions

Recommendation

For a first auction purchase, prefer a voluntary auction. The risks are lower and you can view the property. Forced auctions are best left to experienced buyers.
