Buying in Switzerland?Avoid the mistakes other buyers made.

Swiss and foreign buyers share what went wrong when they bought property in Switzerland. Most of these problems were easy to avoid. Read them before you visit, make an offer or sign anything.

Avoid all the traps

Real experiences, by real people

What the Swiss know about buying, and foreigners learn too late

That the bank values the home itself, and if you pay more than its figure, the gap has to come from your own hard equity. That money paid before the land register entry can be lost if the seller goes bankrupt. That a thin renovation fund in a PPE means special calls for cash later.

Missing just one of these can cost CHF 50,000 to 100,000, often money put aside over a whole career, and years of lying awake over it.

Buyers learn these things the hard way, mention them in a thread, and move on. Nobody gathers them, so the next buyer starts from zero. We gather them and sort them by step, from the Lex Koller check to the transfer tax.

And we go back over the page every week. When the Federal Court upheld Zurich's limits on short lets in June 2026, it went in.

What the Swiss learned at great cost, you can read in a single evening.
