In short A good sale starts with a realistic price and complete documents. Work out all the costs before you decide, including property gains tax. An agent is an option, not an obligation.
The process in seven steps
- Gather documents: land register extract, plans, insurance policy, receipts for renovations.
- Set the price: using comparable listings, a valuation or both.
- Sales file and listing: good photos, clear facts, an honest text.
- Viewings: group appointments, answer questions openly.
- Choose a buyer: ask for a financing confirmation from the bank.
- Purchase contract: The notary certifies the contract and all parties sign.
- Land register and handover: Ownership passes with the entry in the land register.
From preparation to the notary appointment often takes a few months. Plan a buffer if you are buying a new home at the same time.
Setting the price
The price decides everything. Too high, and the listing stays online for a long time and loses appeal. Too low, and you give money away.
- Comparable listings: What do similar properties nearby cost? The Kantello map shows the listings around your property. These are asking prices, not prices actually paid.
- Valuation: Banks and valuers use models based on real sales. For unusual properties, a valuation by a professional is worth it.
- Location and taxes: Buyers also compare running costs. A low tax burden is an argument, as our tax comparison of all cantons shows.
The documents you need
Buyers and their bank ask for documents early. If you have them ready, you come across as reliable and sell faster.
- Land register extract and cadastral plan
- Floor plans with areas and year of construction
- Building insurance policy with the insured value
- Receipts for renovations and investments
- Running costs of recent years
- for condominium ownership: regulations, minutes of recent owners’ meetings and the renovation fund balance
- if available: energy certificate (GEAK)
Private sale or estate agent?
| Route | Cost | Your effort |
|---|---|---|
| Traditional agent | usually 2 to 3 % of the sale price | low |
| Fixed-fee provider | fixed amount, regardless of price | medium |
| Private sale | listings, possibly a valuation | high |
What an agent costs
In German-speaking Switzerland, agents usually charge 2 to 3 % of the sale price for houses and flats. As a rule, the higher the price, the lower the rate. VAT of 8.1 % often comes on top.
| Example | CHF |
|---|---|
| Sale price | 1,000,000 |
| Commission 2.5 % | 25,000 |
| VAT 8.1 % | 2,025 |
| Total | 27,025 |
Commission and services are negotiable. Put both in a written agency agreement.
When an agent makes sense
An agent is mainly worth it if you have little time, live far away or are selling an unusual property. A standard property in a sought-after area, on the other hand, often almost sells itself. That is where the commission weighs most.
Costs for sellers
| Item | Who pays | Amount |
|---|---|---|
| Property gains tax | seller | depends on the gain, canton and holding period |
| Notary and land registry | usually shared, as per contract | on CHF 1 million at most CHF 4,000 in 15 cantons, CHF 7,000 or more in AG, GE and SH |
| Property transfer tax | depends on canton and contract | levied in 19 cantons, not in GL, SH, SZ, UR, ZG and ZH |
| Early repayment penalty | seller | only if a fixed-rate mortgage is ended early |
| Agent’s commission | seller | if an agent is hired |
The agent’s commission and value-adding investments reduce the taxable gain. So keep every receipt.
The purchase contract
- Notary: A contract for the sale of land is valid only if it is publicly notarised. In some cantons an official notary’s office is responsible.
- Reservation: A reservation agreement does not bind the parties to the purchase. A deposit belongs in a blocked account.
- Warranty: It is usually excluded in the contract. But that exclusion does not cover defects you deliberately conceal. Disclose known defects.
- Securing the tax: Many buyers ask for part of the price to go straight to the tax office. This is common and protects both sides.
- Buyers from abroad: For some buyers the Lex Koller applies. Clarify this early.
Where AI helps and where it does not
AI already does a lot of the routine work in a sale. But it replaces neither your judgement nor the notary.
| Task | Does AI help? |
|---|---|
| Drafting the listing text | yes, check the facts yourself |
| Preparing photos | yes, for lighting and perspective; label virtually furnished rooms |
| Gathering comparable listings | yes, as a basis for the price |
| Sorting enquiries and drafting replies | yes, you decide and send |
| Setting the price | only as support, the decision is yours |
| Negotiating | no |
| Legal questions and the contract | no, that is the notary’s job |
The rule behind it
Read whatever AI prepares before anyone else sees it. You remain the seller and are liable for what you state.
Tips for a good sale
- Do the maths early: Estimate the property gains tax before you name a price.
- Be honest: Known defects belong in the sales file. This builds trust and protects you.
- Photos in daylight: Tidy, bright rooms sell better than any text.
- Check financing: Only go to the notary with buyers whose bank has confirmed the financing.
- Plan the date: A few weeks until the next full year of ownership can save tax.
Frequently asked questions
How much does an estate agent cost in Switzerland?
In German-speaking Switzerland, agents usually charge 2 to 3 % of the sale price for houses and flats, often plus VAT. On CHF 1 million that is CHF 20,000 to 30,000. Some providers work for a fixed fee.
Can I sell my house without an agent?
Yes. You need a well-founded price, a complete sales file, listings and time for viewings. A notary always draws up the purchase contract, because it must be publicly notarised.
What costs does the seller pay?
Mainly property gains tax, part of the notary and land registry fees depending on the contract, and in some cantons the property transfer tax. There may also be an agent’s commission and, with a fixed-rate mortgage, an early repayment penalty.
Can AI help with selling a house?
Yes, with routine work. AI drafts listing texts, sorts enquiries, gathers comparable listings and corrects lighting in photos. The price decision, negotiation and legal questions stay with you and the notary. Check what AI writes before you send it.
