Swiss Property Q4 2026: Zero Rates, Empty Flats and Prices That Won’t Blink

Updated 25 September 2026 · 6 min read

Switzerland’s property market is doing what it has done for years: refusing to cool. Borrowing is still cheap by European standards, homes are scarcer than at any point since 2013, and buyers who qualify for a mortgage keep pushing prices up. But three things are changing the mood this quarter: mortgage rates are edging higher, foreign-buyer rules may tighten, and the tax treatment of homes is about to be rewritten.

Interest rates: the SNB stays put, mortgages creep up

On 24 September the Swiss National Bank left its policy rate at 0%, as expected. Inflation has risen since June, mostly because of higher energy prices, but the SNB still forecasts just 0.7% for 2026 and 0.8% for 2027 and 2028, and expects growth of 1.5% to 2% this year. Its next decision is on 10 December.

The catch is that the rest of the world is tightening. Both the euro area and the US have raised key rates recently, and that is feeding into Swiss long-term yields. According to the Moneypark and Helvetia survey, September benchmark rates rose to 2.06% for 10-year fixed mortgages (+8 basis points since June) and 1.83% for 5-year (+14 basis points). Still low, but the era of ever-cheaper money is over.

Prices: still rising, but cooling at the top

Every major index tells the same story: steady growth of roughly 3% to 5% a year, without a bubble-style surge.

Two details stand out. First, momentum is shifting: Fahrländer Partner (FPRE) saw entry and mid-market condominiums gain about 1% in Q2, while the high-end segment eased slightly (-0.3%). Second, holiday and resort markets such as the Engadin, Ticino and Valais are outperforming the national average.

Is it a bubble? The UBS Swiss Real Estate Bubble Index rose from 0.62 to 0.72 in Q2 2026, the level UBS still classes as moderate risk. Its view is that a price correction in the coming quarters looks unlikely.

Supply: vacancy falls below 1% for the first time since 2013

On 1 June 2026, only 45,493 homes stood empty across Switzerland, a vacancy rate of 0.93%. That is 6.1% fewer empty homes than a year earlier and the sixth consecutive annual decline, according to the Federal Statistical Office.

The squeeze shows up in rents. Asking rents rose around 3% year on year in early 2026, according to ReloFinder, and most of the increase lands on new lettings. Sitting tenants are partly shielded: the mortgage reference rate has been 1.25% since September 2025, which keeps indexed rent increases small. New construction, meanwhile, is slow to respond because of high building costs and long approval procedures.

The rules are changing: Lex Koller and the Eigenmietwert

Two policy shifts matter for anyone buying, holding or selling in Switzerland.

1. Lex Koller could tightenOn 15 April 2026 the Federal Council opened a consultation (closed 15 July). Proposals: non-EU/EFTA nationals would need a permit to buy a primary residence and sell within two years of leaving; pure investment purchases of commercial property by foreign buyers would be barred; annual holiday-home quotas would fall from 1,500 to 600, plus a 150-unit reserve. It is a draft, not law, and realistic entry into force is 2028 or later. EU/EFTA nationals are not affected.
2. The Eigenmietwert is goingAfter the 2025 vote, the imputed rental value on primary residences is abolished, along with mortgage-interest deductions on them. From 2028, cantons can levy a property tax on second homes instead. Cantonal rates are expected in 2027, and the overall burden is designed to stay broadly similar.
3. Migration cap rejectedOn 14 June 2026, voters rejected the SVP’s “No to a 10-million Switzerland” initiative with roughly 55% voting No, removing a major uncertainty for housing demand and the EU relationship.

What to watch in Q4 2026

• 10 December: the SNB’s next monetary policy assessment.
• Mortgage rates: whether 10-year fixes keep climbing above 2%.
• October to November: Q3 price indices from IAZI, Raiffeisen and Wüest Partner.
• Lex Koller: the Federal Council’s next step after the consultation.
• Cantons: first draft second-home property tax rates ahead of 2028.
