Want to sell your property in Switzerland but still have an outstanding mortgage? You're not alone — this is the situation for the majority of sellers. In Switzerland, the average mortgage duration rarely exceeds the holding period of the property. The result: most sales involve early mortgage repayment.
The problem? Early repayment can be expensive. Depending on your rate type (fixed or SARON), your bank and your canton, penalties can range from a few hundred to several tens of thousands of francs. This guide explains everything you need to know to value your property, calculate your mortgage exit costs and choose the best strategy.
1. How mortgage repayment works when selling
When you sell a mortgaged property in Switzerland, the mortgage is automatically repaid from the sale proceeds. The notary handles this: they deduct the mortgage amount from the sale price and pay the bank directly before disbursing the balance to you.
The process works as follows:
- Payment order (Tilgungsordre): the notary receives the buyer's funds (or their bank's) and distributes them according to a priority order. The mortgage bank is paid first.
- Mortgage discharge: once the mortgage is repaid, the bank issues a discharge certificate (Schuldbefreiungsquittung). The notary then registers the discharge at the land registry (Grundbuch).
- Balance to the seller: what remains after repaying the mortgage and paying capital gains tax is paid to you.
Good to know: if the sale price is lower than the mortgage amount (a loss-making sale), you still owe the difference to the bank. This is known as the "shortfall risk" — a rare scenario in Switzerland but possible if you took out a 90% mortgage and the market has declined.
The expensive part of this process is not the notary fees or the discharge fees — it's the early repayment penalty, which varies significantly depending on your rate type and bank.
2. Early repayment penalties by canton
In Switzerland, early repayment penalties (Vorfälligkeitsentschädigung) are not governed uniformly by federal law. Each bank applies its own conditions, and some practices vary by canton. Here is an overview of common practices:
| Canton | Fixed rate penalty (estimate) | SARON penalty | Land registry discharge fee |
|---|---|---|---|
| Zurich | Up to 6 months of interest | Generally none | 200 – 400 CHF |
| Geneva | Up to 6 months of interest | Generally none | 300 – 500 CHF |
| Vaud | Up to 6 months of interest | Generally none | 200 – 400 CHF |
| Bern | Up to 3–6 months of interest | Generally none | 200 – 350 CHF |
| Valais | Up to 6 months of interest | Generally none | 250 – 450 CHF |
| Zug | Up to 6 months of interest | Generally none | 200 – 350 CHF |
| Basel-City | Up to 3–6 months of interest | Generally none | 200 – 350 CHF |
| Fribourg | Up to 6 months of interest | Generally none | 200 – 350 CHF |
| Aargau | Up to 6 months of interest | Generally none | 200 – 400 CHF |
| St. Gallen | Up to 3–6 months of interest | Generally none | 200 – 350 CHF |
| Ticino | Up to 6 months of interest | Generally none | 250 – 500 CHF |
| Neuchâtel | Up to 6 months of interest | Generally none | 200 – 400 CHF |
These values are indicative and vary by bank and contract. Always request a discharge offer (Ablöseofferte) from your bank before listing your property for sale.
In practice, early repayment penalties are calculated as follows:
- Fixed rate: the bank compensates for the interest income it loses. The penalty generally corresponds to the difference between your mortgage rate and the current market rate, multiplied by the remaining capital and the remaining term — with a minimum of 0 and a cap often set at 6 months of interest.
- SARON: since the rate adjusts regularly (monthly or quarterly), the bank does not suffer any loss of interest. There is therefore generally no early repayment penalty for SARON mortgages.
Tip: some banks reduce or waive the penalty if you take out a new mortgage with them for a subsequent purchase. Always negotiate this option before selling.
3. SARON vs fixed rate: impact on selling
The type of mortgage rate you chose significantly affects the costs associated with selling your property. Here is a detailed comparison:
Fixed-rate mortgage (Festhypothek)
The rate is locked for an agreed period (2, 5, 10 or 15 years). This is the most common choice in Switzerland — approximately 70% of mortgages are fixed-rate.
- Advantage: complete certainty — you know your monthly payment in advance
- Major disadvantage when selling: early repayment penalty if you sell before the end of the contract
- Typical penalty: 0 to 6 months of interest, calculated based on the difference between your rate and the current market rate, multiplied by the remaining capital and the remaining term
SARON mortgage (variable)
The rate tracks SARON (Swiss Average Rate Overnight) with a fixed margin defined in the contract. It adjusts regularly (monthly or quarterly).
- Advantage when selling: no early repayment penalty — you can sell whenever you want
- Disadvantage: the rate fluctuates, making financial planning more difficult
- Processing fees: administrative fees of 200 to 1,000 CHF typically apply when closing the mortgage account
| Criteria | Fixed rate | SARON |
|---|---|---|
| Planning certainty | High | Moderate |
| Early repayment penalty | Yes (0 to 6 months of interest) | Generally none |
| Closing costs | 200 – 1,000 CHF | 200 – 1,000 CHF |
| Selling flexibility | Low (tied to contract) | High (terminable at any time) |
| Current rate (2026) | 1.5 – 2.5% | 0.8 – 1.5% (SARON + margin) |
| Swiss market share | ~70% | ~30% |
Our advice: if you plan to sell within the next 2 to 3 years, choose a SARON mortgage or a short fixed rate (2 years). If you plan to stay long-term, a fixed rate remains the best option to secure your budget.
4. Calculating mortgage exit costs
Exiting a mortgage in Switzerland involves several costs. Here is a concrete calculation for a property with a mortgage of 500,000 CHF at a fixed rate of 2.0% with 3 years remaining on a 10-year contract:
Worked example
How is the penalty calculated?
In this example, the bank calculates the difference between the contractual rate (2.0%) and the market rate (1.5%), which is 0.5%. This difference is multiplied by the remaining capital (500,000 CHF) and the remaining term (3 years):
0.5% × 500,000 × 3 = 7,500 CHF
Some contracts cap the penalty at 6 months of interest, which in this case would be: 2.0% × 500,000 × 0.5 = 5,000 CHF. In this scenario, the penalty would be capped at 5,000 CHF.
If the market rate is higher than your contractual rate (for example, you have a fixed rate at 1.5% and the market is at 2.5%), the bank suffers no loss of interest and the penalty may be zero — or even reversed (the bank owes you the difference). However, in practice, most contracts include a minimum processing fee.
Tip: request your discharge offer (Ablöseofferte) from your bank before setting the sale price. This document will give you the exact penalty and fee amounts. Note: the offer has limited validity (typically 30 to 90 days).
5. Can you transfer your mortgage to a new property?
Yes, this is possible. A mortgage transfer (Hypotheke übertragen) involves transferring your existing mortgage from one property to another, typically when buying a new property after selling. It's an interesting strategy to avoid early repayment penalties.
Conditions for a mortgage transfer
- Bank approval: the bank must accept the new property as collateral. They will assess the value of the new property and your financial capacity.
- Compatible amount: the transferred mortgage amount must not exceed the collateral value of the new property (generally 80% maximum of the property value).
- Same bank: the transfer is usually done within the same banking institution. Transferring to another bank is equivalent to an early repayment.
- Same conditions: the rate and remaining term are maintained. You cannot renegotiate the existing contract terms.
Mortgage transfer vs early repayment: comparison
| Criteria | Mortgage transfer | Early repayment |
|---|---|---|
| Penalty | None | Yes (fixed rate) |
| Processing fees | 500 – 2,000 CHF | 200 – 1,000 CHF |
| New property flexibility | Must meet bank criteria | Complete freedom for next purchase |
| Rate negotiation | Not possible (conditions maintained) | Possible (new contract) |
| Timeline | Longer (new property assessment) | Quick (immediate repayment) |
When to consider a transfer?
- You are buying a new property right away
- Your fixed rate is higher than the current market rate (the penalty would be high)
- You have more than 2 years remaining on your mortgage contract
- The new property meets your bank's collateral criteria
When is repayment better?
- You are not buying a new property immediately
- Your fixed rate is lower than the market rate (the penalty is low or zero)
- You have less than 1 year remaining on your contract
- You want to switch banks for your next mortgage
6. Selling step by step with a mortgage
Selling a property with an outstanding mortgage follows a specific process. Here are the key steps, in order:
Step 1: Request a discharge offer
Before even listing your property, contact your bank to obtain a discharge offer (Ablöseofferte). This document specifies the exact amount that must be repaid, including:
- The remaining mortgage capital
- Accrued interest
- The early repayment penalty (if applicable)
- Processing fees
This offer has limited validity (30 to 90 days). Remember to renew it if the sale takes time.
Step 2: Get a property valuation
Obtain a professional valuation to set a realistic sale price. This price must cover the mortgage repayment, notary fees, capital gains tax and any penalties.
Step 3: List the property and find a buyer
Publish your listing, organise viewings and negotiate. For more details, see our complete guide on selling an apartment or house in Switzerland.
Step 4: Sign the sale agreement
The sale agreement (Kaufvertrag) sets the price, conditions and date of the final sale. The notary includes the payment order, which guarantees the mortgage will be paid.
Step 5: Mortgage repayment
On the day of the sale, the notary receives the buyer's payment and distributes the funds:
- First: mortgage repayment to the bank
- Second: payment of capital gains tax
- Third: balance paid to the seller
Step 6: Mortgage discharge
After repayment, the bank issues a discharge certificate. The notary registers the mortgage discharge at the land registry. The discharge fees (200 to 500 CHF depending on the canton) are your responsibility.

Can you sell a property in Switzerland with an outstanding mortgage?
Yes, this is the majority of sales. The mortgage is repaid from the sale proceeds. The notary ensures the bank is paid before disbursing the balance to the seller.
What are the penalties for early mortgage repayment in Switzerland?
Penalties depend on the rate type (fixed or SARON), the bank and the canton. For a fixed rate, the penalty can range from 0 to 6 months of interest. SARON generally has no exit penalty, but processing fees apply.
Can you transfer your mortgage to a new property in Switzerland?
Yes, this is possible. This is called a mortgage transfer. The bank must accept the new property as collateral and the amount must match. This avoids early repayment penalties, but the original contract terms are maintained.
What is the difference between SARON and fixed rate when selling?
SARON tracks the SNB policy rate and adjusts periodically. It is more flexible when selling: no early repayment penalty. Fixed rate is locked for the contract duration and incurs penalties for early repayment.
How do you calculate mortgage exit costs in Switzerland?
Exit costs include: the early repayment penalty (0 to 6 months of interest for a fixed rate), bank processing fees (200 to 1,000 CHF), land registry discharge fees (200 to 500 CHF depending on the canton), and any notary fees.
Does the seller or buyer pay the mortgage repayment?
The seller repays the mortgage from the sale proceeds. The notary deducts the mortgage amount from the sale price and pays the bank directly before disbursing the balance to the seller.
