Minimize financial risks: tips for clever investors

Foreclosures in Switzerland are a magnet for yield-hungry investors, but they also present pitfalls when budget, taxes, or liquidity are underestimated. The good news is that with a few well-thought-out measures, the greatest risks can be mitigated without compromising the price advantage gained from the auction. The following strategies draw on best practices from banks, building economists, and experienced auction participants.

1 What Risks Are Lurking, and Where?

Risk Type	Typical Cause	Impact on Return
Price Risk	Overly optimistic bidding behavior in hot phases	Less buffer for renovation & sale
Liquidity Risk	20-day payment deadline, refinancing fails	Forced realization process + fees
Interest Rate Risk	SARON increase over 2 percentage points	Cash flow erosion, higher affordability
Technical Risk	Asbestos, pipe breaks, structural damage	Cost explosion, construction delays
Tax Risk	Continuation of low valuation, later capital gains tax	Tax burden at exit increases by up to 20%

“Risk is not a coincidence: The earlier you identify potential cost drains, the smoother the investment will go.”

2 Smart Financing Setup

2.1 Interim Financing + Mortgage = Double Protection

• Interim loan (max. 3 - 6 months) secures the 20-day deadline. Agree on 0 CHF prepayment penalties.
• Finalize mortgage only after land registry entry. Combine SARON for flexibility and fixed mortgage for interest rate security.
• Include a reserve account of ≥ 5% of the purchase price: covers interest increases & unexpected repairs.

2.2 The Second-Lien Lever

Renovation loans in the second mortgage rank cost 0.5% more interest but reduce equity binding. This keeps capital available for diversification, see Chapter 3.

3 Don’t Invest Everything in One Hammer

1. Mix Geography: Significant price and tax differences across Switzerland, a mix smooths out fluctuations.
2. Split Usage Types: Residential, commercial, parking garages… different economic cycles.
3. Combine Vehicles: Direct acquisition + real estate funds/REITs reduces concentration risk.

4 Examine Technical Risks Early

4.1 “Drive-By” is Not Enough

Inspect basements, attics, and technical rooms at the latest on the official viewing date. Use a building thermography for 300-500 CHF: It uncovers moisture and insulation deficiencies without demolition.

4.2 Pre-Auction Assessment

Checklist (abridged):
✓ Roof / Facade - Condition report & cost estimate
✓ Electrical system - Diameter ≥ 13 A? RCD switch available?
✓ Plumbing - Year of copper/PE? Risk of corrosion?
✓ Heating system - Efficiency, CO₂ classification

5 Tax Strategy = Risk Buffer

• Declare renovation costs as value-preserving, immediately deductible, reducing liquidity risk.
• Capital gains tax brake: Holding period ≥ 5 years reduces tax rate by up to 40% (cantonal).
• Holding company or simple LLC for multi-family houses: lower corporate tax rate, potential loss carryforward.

6 Quick Scenario: How Much Buffer Do You Need?

Scenario	Cash Flow ↓ by	Recommended Reserve
Interest rate increase +1%	CHF 9,600 p.a.	1 year’s burden in savings account = CHF 10,000
Rental loss 3 months	CHF 6,750	Rental deposit insurance + liquidity buffer CHF 7,000
Total renovation of heating	CHF 32,000	Provision in Renewal Fund

7 Practical Example: How Marco Halved His Risk

Marco acquires a three-family house in Winterthur in 2024 (hammer price CHF 1.35 million). He deposits a security of CHF 135,000, takes out a 3-month SARON interim loan, and switches to a 60% fixed mortgage at 1.72% interest after land registry entry. He operates another 20% via a SARON tranche with an interest cap of 2.5%. At the same time, he pays CHF 1,000 a month into a renewal fund. His effective risk buffer (cash + fund) is thus CHF 62,000, enough to cover one year of vacancy or a heating failure. After 18 months of refinancing, the bank increased the collateral value due to renovation, allowing him to pay off the expensive second-lien tranche.

8 Quick Checklist for Savvy Investors

1. Provide security deposit + 5% cash reserve before the auction.
2. Contractually cap the interest and costs of interim financing.
3. 100-point assessment: Roof, wiring, structure, building technology.
4. Interest stress test: simulate +2%, cash flow must remain positive.
5. Define tax exit strategy at the time of purchase.
6. Feed the renewal fund from day 1, target ≥ CHF 50/m² living area.
7. Portfolio diversification: max. 25% equity per property.

9 FAQ

Can I secure the security deposit with securities?

Yes, a Lombard loan on liquid securities often covers up to 70% of the portfolio value and is available within 24 hours. Ask the bank for a Blocking Letter instead of cash.

How do I protect myself against rental loss?

In addition to classic rental deposit insurance, a landlord's legal protection policy is worth considering. It covers legal and court costs in eviction lawsuits.

Is an interest cap or forward fixing worth it?

For a long holding period ≥ 10 years: Yes, as long as the premium is < 0.3% p.a. With a short holding period, typically a SARON tranche plus reserve account suffices.

10 Conclusion: Manage Risk, Secure Return

Financial risks in foreclosures are manageable if you proactively manage liquidity, interest, and the condition of the property. Use interim financing, reserve funds, and tax levers to build a buffer instead of problems. This way, the bidding war becomes a clearly calculable investment with an attractive risk profile.
