Selling property: why fast is not automatically good

Key points at a glance

Anyone selling a property is often told to accept the first good offer. Sometimes that is right. Often, though, speed is confused with quality. A deal after two weeks is worth little if the buyer’s financing is shaky, the handover date clashes with your move or the price is below market.

Compare offers by price, financing security, timing and conditions.
Ask for reliable proof of financing before the notarised signing.
Plan the transfer of ownership so that it fits your own housing situation.
Factor in taxes and costs before comparing offers.

Why speed can be deceptive

A very quick sale can be a sign that the asking price was too low. If several interested parties accept it within days, the market has told you something. Conversely, a quick yes from a single party is not yet a deal: in Switzerland, a property purchase only becomes binding once the contract is publicly notarised, and ownership passes on entry in the land register.

Until then, buyers can pull out, for example because the bank assesses affordability differently than expected. Reservation agreements that are not notarised offer only limited security. If you have turned other bidders away at this stage, you lose time and have to restart marketing, often with the stigma of a property that has already failed to sell once.

The best deal is not the fastest one, but the one that fits your situation best overall.

Comparing offers properly

A structured comparison protects you from gut decisions. Put the offers side by side and assess each criterion separately.

Criterion	What to check	Warning sign
Price	Is it in line with an independent valuation?	Well below comparable properties
Financing	Is there written financing confirmation from a bank?	Only a verbal commitment, unclear equity
Payment guarantee	Will an irrevocable bank payment undertaking be provided?	Payment only after handover or in instalments
Timing	Does the handover date fit your move?	Rigid date with no flexibility
Conditions	Are there reservations, such as the sale of another property?	Several open conditions at once

An example: offer A is CHF 20'000 higher but depends on the buyers selling their current flat. Offer B is slightly lower, financing is confirmed and the date is flexible. For many sellers B is the better deal, because the risk of the buyer withdrawing is much smaller.

Checking financing and payment guarantees

Swiss banks generally require at least 20 percent equity for residential property and test affordability using an imputed interest rate well above current market rates. A buyer who does not clear these hurdles comfortably is a risk, however quickly they want to sign.

Ask to see written confirmation of financing, not just a preliminary assessment.
Ask where the equity comes from, for example savings, pension fund or an advance on inheritance.
Agree that an irrevocable bank payment undertaking will be available at the notarised signing.
Clarify whether a deposit will be paid when the contract is signed.
Set out withdrawal rules and deadlines clearly in the purchase contract.

Planning timing, taxes and costs

A fast sale is of little use if you then have to rent temporarily or organise two moves. Align the handover date with your own next step. Also agree the condition in which the property will be handed over and who is responsible for maintenance and insurance until then.

Clarify taxes early

A cantonal property gains tax is usually due on the sale, and the amount depends heavily on how long you have owned the property. Depending on the canton, a transfer tax plus notary and land register fees may apply. Rules differ between cantons and change over time; have a tax specialist calculate your current situation.

Only once these items are known can you judge which offer is really worth more in the end. Careful marketing with complete documentation, professionally run viewings and a transparent comparison of offers usually takes a few weeks, but often saves renegotiations and withdrawals.

Frequently asked questions

Should I turn down the first offer if it matches the asking price?

Not automatically. Check financing, timing and conditions. If several full-price offers arrive within a short time, however, it is worth reconsidering the price and the process, for instance with a short bidding round.

When does a property sale become binding in Switzerland?

Only when the purchase contract is publicly notarised. Ownership passes on entry in the land register. Verbal commitments and simple reservations offer only limited security.

What is an irrevocable payment undertaking?

The buyer’s bank commits to transferring the purchase price when ownership is transferred. This largely secures the payment. Make sure it is in place by the notarised signing.

How long does a careful sale take?

That depends on location, property and market conditions. Preparation, marketing, viewings and notarisation usually take several weeks to a few months. More important than the duration is that the steps are properly coordinated.

Do I need professional support to sell?

Not necessarily, but expertise helps with valuation, contract and taxes. Obtain at least one independent valuation and have the draft contract reviewed before notarisation.

If you look at price, security and conditions together, you will decide more calmly and usually better than under the pressure of a quick yes.
