The Rental Guarantee in Switzerland: The Financial Shock

"CHF 7,200 deposit?! But I only have CHF 8,000 in savings!"

When Thomas signed his Zurich lease (CHF 2,400/month), reality hit him. His 3-month deposit—CHF 7,200—was going to wipe out almost all of his savings. He had CHF 800 left to furnish his apartment, eat for the first month, and manage unforeseen expenses.

He had to borrow CHF 3,000 from his family to survive until his first salary.

The Swiss rental guarantee is one of the most underestimated and financially violent aspects for newcomers. Three months' rent blocked for years—for many, it's more than their total savings. This guide explains how this system works and how to optimize it.

Key figure: According to real estate statistics, the average rental guarantee in Switzerland is CHF 6,800, representing 4-6 months of savings for the median tenant (source: Wüest Partner).

Why 3 Months? The Swiss Logic

In France, the deposit = 1 month's rent. In Switzerland, it's 3 months. Why this brutal difference?

Landlord Protection

Eviction procedures in Switzerland are slow (6-12 months minimum). If a tenant stops paying, the landlord can lose 6-9 months of rent before recovering the property.

The 3-month deposit partially covers this risk. It's an insurance logic, not a punitive one.

The Blocked Account System

Unlike in France where the landlord keeps your check, in Switzerland your money goes into a BLOCKED bank account. Neither you nor the landlord can touch it.

Sophie has CHF 7,800 in her blocked account for 4 years. The landlord cannot use this money. Sophie can't either. It sleeps, generating 0.5%/year interest (CHF 39/year—ridiculous).

The Swiss paradox: Your money is ultra-secure, but completely useless for years.

The Three Possible Solutions

Solution 1: The Blocked Account (70% of Cases)

How it works: You go to your bank with a signed lease. You open a "rental guarantee" account with CHF X in it. The bank issues a blocking certificate in the name of the landlord. The landlord accepts, you move in.

Marc, apartment CHF 2,200/month, blocked CHF 6,600 at PostFinance.

Advantages:

• Accepted by 100% of landlords
• Your money remains yours (technically)
• Guaranteed recovery at the end of the lease

Disadvantages:

• Capital immobilized for years
• Ridiculous interest (0.5%)
• Drastically reduced liquidity

Cost: CHF 20-50 account opening + CHF 10-30/year management

Solution 2: The Surety Insurance (25% of Cases)

How it works: You take out surety insurance (Swisscaution, AXA-ARAG, etc.). The insurance guarantees the landlord payment if you don't pay. You pay an annual premium instead of blocking capital.

Julie, apartment CHF 2,400/month (deposit CHF 7,200), pays CHF 240/year to Swisscaution.

Calculation over 5 years:

• Blocked account: CHF 7,200 immobilized + CHF 200 lost interest
• Insurance: CHF 1,200 paid (5 × CHF 240)
• Insurance savings: CHF 6,000 of available liquidity for 5 years

Advantages:

• Keep your liquidity
• Premium sometimes tax deductible
• Financial flexibility

Disadvantages:

• 30% of landlords refuse
• Real cost CHF 150-300/year (lost)
• Financial health questionnaire

For whom:

• You have limited savings
• You want to keep capital available
• Landlord accepts (check BEFORE signing the lease)

Solution 3: Mix Account + Cash (5% of Cases)

Some landlords accept a partial guarantee (1-2 months blocked + 1-2 months cash). Rare, but negotiable in certain situations.

Vincent, excellent file (permanent contract, high salary), negotiated 2 months blocked + 1 month cash in Berne. Savings: CHF 2,400 of released capital.

For whom: Solid file + flexible landlord + calm rental market = rare combo.

The Complete Process in 5 Steps

Step 1: Signing the Lease

You sign the lease. The guarantee clause specifies: amount (generally 3 months) + modality (blocked account or accepted insurance?).

ATTENTION: Check this clause BEFORE signing. Some leases accept insurance, others do not.

Step 2: Establishing the Guarantee (Within 30 Days)

Blocked account option: Bank appointment, account opening, transfer of CHF X, issuance of blocking certificate. Duration: 1-2h total.

Insurance option: Online subscription to Swisscaution/other, payment of annual premium, certificate issued instantly. Duration: 15 minutes.

Step 3: Handing Over the Certificate to the Landlord

The landlord receives the certificate proving the guarantee has been established. He gives you the keys. You move in.

Step 4: Life During the Rental

Your guarantee sleeps peacefully. You no longer see it, no longer touch it. It just exists, blocked, in the background of your life.

Step 5: Recovery at the End of the Lease

Exit inventory OK: The landlord signs the release of the guarantee. Your bank releases the funds within 2-4 weeks. You recover the capital + negligible interest.

Exit inventory with damage: The landlord calculates repairs (quotes). You dispute or accept. Amount deducted from the guarantee. The remainder is returned to you. Disputes → mediator or court (slow, CHF 500-2,000 fees).

Key Points to Remember

The Swiss rental guarantee of 3 months represents a major financial obstacle to settling in, requiring CHF 6,000-9,000 blocked. Three essential principles: Firstly, budget for settling in Switzerland with month 1 rent + 3 months deposit + furniture + unforeseen expenses = CHF 12,000-18,000 minimum total—many underestimate and borrow from family/friends in a panic. Secondly, surety insurance saves CHF 150-250/year vs blocked capital (0.5% interest) but only 70% of landlords accept it—check before signing the lease. Thirdly, guarantee recovery takes 2-8 weeks after departure if the accommodation is spotless, up to 6-12 months if there are disputes—do not count on this money immediately to finance your next move.

Plan for this blocked capital as "lost" temporarily and keep a separate savings buffer to live on—a common mistake is to empty all savings into the deposit and then struggle financially afterwards.
