Quick answer
For a CHF 10 million chalet, the largest yearly items are a reserve for future works (CHF 50,000–100,000), wealth tax (CHF 30,000–50,000) and the tax effect of the imputed rental value (CHF 20,000–50,000). Maintenance, heating, property management, insurance, grounds and cleaning make up the rest.
A CHF 10 million chalet in Gstaad typically costs CHF 130,000 to 300,000 per year to own, before any mortgage, once taxes and a reserve for future works are included. That is roughly 1.3 to 3 percent of the property's value. Below is where the money goes.
The 1 Percent Rule and Why It Often Understates Reality
Swiss banks and property advisors use a rule of thumb: annual maintenance and running costs equal about 1 percent of the property's market value. For a CHF 8 million chalet, that suggests CHF 80,000 per year.
The rule works as a floor, not a ceiling. In practice, larger chalets with pools, wine cellars, saunas, landscaped grounds, and multiple fireplaces cost more. Older chalets needing periodic renovation can push the figure to 2 percent or above. A newer, well-built property might run closer to 0.7 percent for the first decade.
Mandatory Building Insurance (GVB)
In Canton Bern, building insurance is provided by the cantonal insurer, Gebäudeversicherung Bern (GVB). It is mandatory and transfers automatically with the property.
Premiums are based on the building's replacement cost (not market value) and the natural-hazard risk zone. For a Saanenland chalet, expect CHF 1,000 to 5,000 per year. A large chalet in a higher-risk zone (avalanche, flooding) will be at the upper end.
Property Taxes and Wealth Tax
Wealth Tax (Vermögenssteuer)
Gstaad is in Canton Bern. The canton taxes the market value of your property as part of your total net wealth. Bern's wealth tax rates are progressive, starting at around 0.1 percent for modest fortunes and reaching approximately 0.5 percent at the highest brackets for cantonal and municipal tax combined.
For a non-resident who owns only a Gstaad chalet worth CHF 10 million, the effective wealth tax rate on the property might be CHF 30,000 to 50,000 per year, depending on individual circumstances and any applicable lump-sum taxation arrangement.
Eigenmietwert (Imputed Rental Value)
If you own a residential property in Switzerland, the tax authorities impute a fictional rental income, called the Eigenmietwert, typically set at 60 to 70 percent of the fair market rent. This is added to your taxable income whether or not you rent the property.
For a Gstaad chalet that could rent for CHF 200,000 per year, the imputed rental value might be CHF 120,000 to 140,000, taxed at your marginal income tax rate.
The good news: mortgage interest and maintenance costs are deductible against this income. Owners can choose between actual documented costs or a flat-rate deduction (10 percent of Eigenmietwert for properties up to 10 years old, 20 percent for older properties at the federal level).
Important change ahead: A federal vote on 28 September 2025 approved the abolition of Eigenmietwert for primary residences, effective 1 January 2029. However, for second homes, including most Gstaad chalets owned by non-residents, the imputed rental value system is expected to remain in place. The details are still being finalised. Talk to a Swiss tax advisor for current guidance.
Property Transfer Tax (Handänderungssteuer)
This is a one-time cost at purchase, not annual. In Canton Bern, it is 1.8 percent of the purchase price, split equally between buyer and seller unless agreed otherwise.
Heating and Energy
Oil Heating
Many older chalets in the Saanenland run on oil (Heizöl). A 3,000-litre fill costs approximately CHF 3,000 to 4,000 at recent prices. A large chalet used year-round may need 5,000 to 8,000 litres per year, costing CHF 5,000 to 10,000.
Oil prices have been volatile. In 2022, costs roughly doubled compared to 2020 levels. Several Saanenland properties are transitioning to heat pumps or connecting to municipal district heating networks (Fernwärme), which reduces both cost and carbon footprint.
Heat Pumps and Renewable Energy
A ground-source heat pump can cut annual heating costs by 50 to 70 percent compared to oil but requires a significant upfront investment (CHF 40,000 to 80,000 installed). Air-source heat pumps are cheaper to install but less efficient in Gstaad's cold winters.
Electricity
Electricity in the Saanenland is provided by BKW (Bernische Kraftwerke). A chalet with electric underfloor heating, pool, sauna, and full household use might consume CHF 3,000 to 8,000 per year in electricity, depending on the setup.
Property Management
If you do not live in your chalet year-round, and most Gstaad chalet owners do not, a property manager or caretaker (Hauswart) is essential. Services typically include:
- Regular inspections (weekly or fortnightly)
- Heating management and winterisation
- Snow removal from access paths and roofs
- Garden and grounds maintenance
- Coordinating cleaning before and after visits
- Managing tradespeople for repairs
- Mail and deliveries
A professional property management company in the Saanenland charges CHF 5,000 to 20,000 per year for a single chalet, depending on the scope. A full-service arrangement with a dedicated caretaker for a large estate can reach CHF 30,000 or more.

Maintenance and Repairs
Routine Maintenance
Regular upkeep for an alpine chalet includes:
- Exterior wood treatment: Chalets with exposed timber facades need reapplication of protective stain every 3 to 5 years. For a large chalet, budget CHF 10,000 to 30,000 per cycle.
- Roof inspection: Annual checks for storm, snow, or ice damage. Minor repairs CHF 1,000 to 3,000. A full roof replacement on a traditional chalet can exceed CHF 100,000.
- Plumbing and heating service: Annual boiler servicing CHF 500 to 1,500. Pipe insulation checks before winter are critical. Burst pipes in an unheated chalet cause catastrophic damage. See: Winterising Your Gstaad Chalet
- Chimney sweeping: Required by law in Canton Bern. CHF 200 to 500 per chimney per year.
- Garden and landscaping: CHF 3,000 to 15,000 per year for lawn, hedges, and alpine planting.
Reserve Fund
Experienced owners budget a sinking fund of 0.5 to 1 percent of property value per year for larger periodic works: kitchen and bathroom renovations, facade restoration, heating system replacement, and structural repairs. On a CHF 10 million property, that is CHF 50,000 to 100,000 per year set aside.
Contents Insurance and Liability
Cantonal building insurance (GVB) covers the structure. Everything inside, furniture, art, wine, electronics, personal belongings, requires separate contents insurance (Hausratversicherung).
For a well-furnished luxury chalet, premiums typically run CHF 2,000 to 8,000 per year. If the property contains art, jewellery, or collections, specialised high-value cover adds to this.
Personal liability insurance (Privathaftpflicht) is separate and costs CHF 200 to 500 per year.
Cleaning
Professional cleaning before and after owner visits, plus deep cleaning two to four times per year, costs CHF 3,000 to 10,000 per year. Properties with short-term rental activity will spend significantly more.

Individual costs vary widely based on the property's age, size, condition, how much time you spend there, and whether you rent it out.
How to Reduce Annual Costs
- Energy upgrades: Replacing oil heating with a heat pump reduces heating costs and may qualify for cantonal energy subsidies.
- Strategic renovation timing: Alternating years of high and low maintenance spend lets you maximise tax deductions in Canton Bern.
- Insurance review: Ensure the GVB insured value matches the actual replacement cost. Over-insurance wastes money. Under-insurance risks partial payouts.
- Property management: A reliable local manager prevents expensive emergency repairs caused by neglect (frozen pipes, roof damage).
Frequently Asked Questions
What percentage of a chalet's value should I budget for annual costs?
Budget 1 to 2 percent of the property's market value for annual running costs, excluding taxes. Including wealth tax and Eigenmietwert, the total can reach 2 to 3 percent.
Are chalet maintenance costs tax-deductible in Switzerland?
Yes. Actual maintenance costs or a flat-rate deduction (10 or 20 percent of Eigenmietwert depending on the property's age) can be deducted from taxable income. Renovations that increase the property's value (improvements) are not deductible as maintenance but may reduce future capital gains tax.
Will the Eigenmietwert abolition affect Gstaad chalet owners?
The abolition approved in September 2025, effective 2029, applies to primary residences. For second homes, the Eigenmietwert is expected to remain. Details are being finalised. Consult a Swiss tax advisor.
What happens if I leave a chalet unoccupied without a caretaker?
Frozen and burst pipes, snow damage to the roof, security risks, and insurance complications. GVB may reduce or deny claims if a property was left unheated and unmonitored during winter. A caretaker or property manager is not a luxury. It is a necessity.
