The cheapest money in this series, and a door most foreigners can’t open

For a lot of internationals, Switzerland and Germany represent two different investing cases entirely. Germany is famous for being a nation of renters, fewer than half of households own. So it's a genuine surprise to learn that its wealthy southern neighbour renters even more. Switzerland has the lowest homeownership rate in the developed world, around 36%, and it got there deliberately, through a mix of eye-watering prices, a peculiar tax on owning, and a rental market so good that most people simply never bother to buy.

For an investor, that inversion makes Switzerland one of the most interesting comparisons in this series, and often the opposite of what you'd expect. Swiss mortgages are the cheapest around; Swiss buying costs can be near zero; yet Switzerland taxes property wealth every year, taxes every sale, and, through the Lex Koller law, mostly won't let a foreigner buy a home at all. Germany, by contrast, taxes ownership lightly, hands long-term owners a tax-free exit, and welcomes foreign buyers.

This article compares both systems, neutrally, across seven dimensions. One caveat up front: Switzerland has 26 cantons, each taxing differently, so many figures below are ranges, "it depends on the canton" is doing real work. Figures are current as of mid-2026 and sourced inline. The companion piece covers the broader market: Germany vs Switzerland, the housing-market deep dive.

1. Financing: the cheapest money in the series

If there's one dimension where Switzerland simply comes out ahead, it's the cost of borrowing. In mid-2026 a 10-year fixed Swiss mortgage cost roughly 1.5 to 2.05%, and a SARON (variable) mortgage carried a margin of just 0.7 to 1.2% over a low base (UBS). German investment-property financing sits around 4 to 5% (based on Financemate's current customer financing data, for a non-owner-occupied investment loan; the broader average across all new German home loans, including owner-occupiers, is lower, around 3.7%), well over double the Swiss rate either way. Swiss financing is also structurally distinctive: it comes in two tiers. The first mortgage (up to 65% of value) carries no obligation to repay, you can keep it indefinitely, while the second (65 to 80%) must be amortized down to 65% over about 15 years. Buyers need 20% down, of which at least 10% must be "hard" equity (the rest can come from pillar 2/3a pension savings).

That structure, combined with the tax system, historically produced a well-known Swiss habit: never fully repaying your mortgage. Because mortgage interest was tax-deductible and owners were taxed on imputed rent anyway (more on both below), keeping a big first mortgage forever was rational. That logic is now weakening, but the rates remain the lowest in this comparison by a wide margin.

Where the costs are lower: Switzerland, clearly and by a wide margin, the cheapest mortgages in the series, with a uniquely flexible repayment structure.

2. Entry costs: often near zero

Here too Switzerland is unusually light, the mirror image of Germany's heavy purchase taxes. Swiss buying costs are cantonal: the transfer tax (Handänderungssteuer) ranges from around 0% to about 3.3%, and some cantons, notably Zurich, charge none at all, leaving only notary and land-registry fees of roughly 0.5 to 1% (Global Property Guide). Germany's Grunderwerbsteuer of 3.5 to 6.5% plus notary and agent fees totals 8 to 12%. Getting into a Swiss property can cost a fraction of what it costs in Germany, the catch being that Swiss prices themselves are among the highest on earth, and you need a fifth of the value in cash up front.

Where the costs are lower: Switzerland, by a wide margin on transaction taxes, even if the underlying prices are steep.

3. Rental-income tax: it depends on the canton

For a buy-to-let investor, rental income in Switzerland is taxed as ordinary income at combined federal, cantonal, and communal rates, with mortgage interest and maintenance deductible. The headline here is variance, not level: a low-tax canton like Zug taxes income far more gently than a high-tax one like Geneva, so the same rental profit can face very different bills a canton apart. Germany taxes rent at your marginal rate (up to 42 to 45%) with full deduction of actual costs. In a low-tax Swiss canton an investor may pay less than in Germany; in a high-tax one, similar or more.

There's also the well-known Swiss wrinkle that applies to owner-occupiers, not landlords: the Eigenmietwert (imputed rental value), covered under culture below, until recently, Swiss homeowners were taxed on a fictional rent for living in their own home.

Where the costs are lower: roughly even, Switzerland's cantonal spread means low-tax cantons undercut Germany while high-tax ones don't.

4. Depreciation: a German tool Switzerland doesn't give individuals

Germany lets a landlord depreciate the building through AfA, 2 to 3% a year, plus 5% for qualifying new builds, a standing deduction against rental income. Switzerland offers private individuals no equivalent depreciation on residential property: you can deduct actual maintenance costs (and Switzerland is generous about what counts as deductible upkeep), but there's no cost-based building write-down for a private investor; depreciation is reserved for business and commercial assets.

Where the costs are lower: Germany, AfA is a real, compounding shield with no Swiss counterpart for private residential investors.

5. The exit: always taxed vs tax-free after ten years

When you sell in Switzerland, the gain is always taxed, through the cantons, via the Grundstückgewinnsteuer (real-estate gains tax), whose rate depends heavily on how long you held. Rates run from roughly 10% to 60%: high for a quick flip, falling steadily the longer you own, but in most cantons never reaching zero (Comparis). (There's no federal capital-gains tax on private assets, but real estate is the cantonal exception.) Germany, by contrast, makes a privately held property completely tax-free to sell after a ten-year hold.

So the two systems share a philosophy, reward long holding, discourage speculation, but land differently: Switzerland tapers the tax down over decades yet rarely to nothing, while Germany simply switches it off at year ten.

Where the costs are lower: Germany, the clean tax-free exit beats Switzerland's tapered-but-persistent cantonal gains tax, especially for the very long-term owner.

6. Ongoing property tax: Switzerland taxes your wealth

Switzerland's annual burden is distinctive because it runs through the wealth tax. Every canton levies an annual tax on your net wealth, including the value of your property, net of mortgage, at roughly 0.1 to 0.8% (PwC), and some cantons add a small property tax (Liegenschaftssteuer). Until the 2025 reform, owner-occupiers also paid income tax on the Eigenmietwert. Germany, by contrast, has a light annual Grundsteuer and no wealth tax at all.

For an investor building a portfolio, the Swiss wealth tax is a genuine recurring cost that Germany doesn't impose, though it's partly offset by the fact that the mortgage reduces your taxable net wealth, which is one more reason Swiss owners kept their mortgages large.

Where the costs are lower: Germany, no wealth tax and a light annual charge, versus Switzerland's cantonal wealth tax on property.

7. Cultural attitudes: the world's most comfortable renters, and a landmark reform

Switzerland is the ultimate renting nation. At around 36% homeownership it sits below Germany and at the very bottom of the developed world; in the city of Basel barely 16% own (Investropa). This isn't a story of people locked out and resentful, as in parts of Spain or India, Swiss renting is a genuinely good deal: high-quality stock, strong tenant protections, a large cooperative-housing sector, and deep social acceptance. Owning simply isn't the marker of having "arrived." Two forces pushed ownership down: some of the world's highest prices (Zurich near CHF 19,000/m²), and a uniquely Swiss tax, the Eigenmietwert, under which homeowners paid income tax on a notional rent their own home "could" earn, blunting the financial case for buying.

That second force is now being dismantled, in one of the larger housing reforms anywhere. On 28 September 2025, Swiss voters abolished the Eigenmietwert (57.7% in favour), to be implemented during 2026 and take effect around 2028 to 29; the same reform removes the owner-occupier mortgage-interest deduction and adds a new cantonal tax on second homes (SwissInfo). Over time it could nudge Swiss ownership upward and end the never-repay-your-mortgage habit that the old system encouraged.

Germany's renting culture is the same species, milder in degree: stable, respected, ownership near 47%, savings channelled into financial products. The two countries are, in effect, the German-speaking world's twin renting societies, Switzerland simply took it further, for reasons of price and tax that it is now, partly, unwinding.

Where this leaves you: neither is better, but note the direction. Both are renting cultures; Switzerland's is the more extreme, built on high prices and the Eigenmietwert, and it's the one now reforming. For a German-speaker moving between the two, the mental model is familiar, renting is normal in both, while the investor mechanics (cheap money, cantonal taxes, Lex Koller) are very different.

Which one fits your plan?

The Swiss and German cases split cleanly, in opposite directions on almost every axis. Switzerland offers the cheapest financing in this series by far, very low purchase costs, a strong rental market, and, in low-tax cantons, gentle income tax, all wrapped in extreme stability and a strong currency. Germany offers a leaner long-run structure: AfA depreciation, no wealth tax, and a clean tax-free exit after ten years that Switzerland's cantonal gains tax never quite matches.

But for most international readers, one factor overrides the tax detail: access. Germany lets a foreigner buy freely; Switzerland, through Lex Koller, mostly does not. Non-residents generally cannot buy a Swiss home at all, the country issues only about 1,500 holiday-home permits a year nationwide, in designated tourist zones, and a 2026 government consultation aims to tighten the rules further, even for non-EU/EFTA buyers of primary residences (Nievergelt & Stöhr). For many would-be buyers, that alone decides it: Germany is open; Switzerland is, by design, largely closed.

So the honest answer depends on who you are. If you live in Switzerland and can buy, the cheap money and low entry costs are notable; if you're an outside investor, Germany is both more accessible and, on the exit and the wealth tax, structurally lighter. And whatever you conclude, remember the cantons: a Swiss "average" hides 26 different tax regimes, so any real decision is a cantonal decision. Run your actual numbers, in the actual canton, before trusting any national figure.
