Lake Constance property market: prices in Konstanz and Lindau

An apartment on the German shore of Lake Constance (Konstanz in Baden-Württemberg and Lindau in Bayern combined) is listed at an average asking price of €5,653 per m² in Q3 2026, and a house at €6,129 per m², according to Area Insights, the source of the price series on this page. These are asking prices from indexed listings, not transaction prices. Apartment asking prices are down 0.9% on a year earlier and have moved sideways since 2025 after a 2023 dip. Germany places no restrictions on non-resident buyers, yet Konstanz levies the country's highest second-home tax and requires a permit to let a flat to holidaymakers.

Picture a Zürich-based couple viewing a period flat in the Konstanz Paradies quarter on a Saturday afternoon. Coming from Switzerland, they are pleasantly surprised that the asking price per square metre is well below what they would pay along Lake Zürich. The surprise arrives later at the notary's office: the city will tax their weekend apartment at 35% of its notional annual rent, and the ten-week annual holiday-let allowance is all they will ever be granted without a formal permit. That is the German shore of the Bodensee in a single scene. The lake looks approachable next to Swiss price levels, but the municipal rules, rather than the prices, are what catch buyers from abroad off guard.

What does property cost on Lake Constance in 2026?

In Q3 2026, the average asking price for an apartment across Konstanz and Lindau combined is €5,653 per m² (-0.9% year on year), while houses stand at €6,129.4 per m² (-1.2% year on year), according to CASAFARI Area Insights (location ids 527264 and 529309, queried 23 October 2026). Both figures represent asking prices from indexed listings with statistical outliers excluded; in a calm, sideways market, achieved transaction prices typically sit below initial asking levels.

To put those numbers in perspective, buyers are looking at a major-city price level for two lakeside municipalities that count roughly 87,000 and 26,000 inhabitants respectively. At €5,653 per m², a standard 90 m² apartment across Konstanz and Lindau combined lists at roughly €510,000 on average, with prime lakefront and Altstadt stock asking considerably more.

Scope matters when reading these figures. This series tracks the municipalities of Konstanz and Lindau (Bodensee) combined, lying 60 km apart in two different federal states. Other popular towns on the German shore—such as Friedrichshafen, Überlingen and Meersburg—as well as the Swiss and Austrian shores of the lake, are outside this dataset.

How have prices moved since 2023?

The market on the German shore has spent the past year and a half in a narrow corridor. Apartment asking prices in Konstanz and Lindau combined slid from €5,881.9 per m² in Q1 2023 to a trough of €5,157.3 per m² in Q4 2023 (-3.9% over the full series to Q3 2026), before recovering by 9.6% between Q4 2023 and Q3 2026, according to CASAFARI Area Insights. For the past six quarters, the combined apartment average has stayed quietly inside a band of €5,577.5 to €5,703.5 per m².

For houses in Konstanz and Lindau combined, the Q3 2026 average asking price of €6,129.4 per m² is down 1.2% compared with €6,205.3 per m² in Q3 2025, and down 7.6% against the €6,633 per m² recorded in Q1 2023. Because the detached house market in both lakeside towns is thin, a handful of large villa listings can move a single quarter noticeably—the series dipped to €4,981.5 per m² in Q3 2023 and reached €6,655 per m² in Q3 2024. Advisers and buyers should read the multi-year direction rather than any single quarter.

Looking at annual averages smooths out that quarterly noise and shows the plateau clearly.

Year	Apartments (€/m², asking)	Houses (€/m², asking)
2023	€5,512.3	€5,997.7
2024	€5,421.0	€6,243.0
2025	€5,652.9	€6,279.1
2026 (Q1–Q3)	€5,637.3	€6,078.7

Is Lake Constance following the German market?

Nationally, the provisional Destatis house price index, Q2 2026 (published 24 September 2026) rose by 0.6% year on year and 0.3% compared with Q1 2026. Set against that national reading, the Q3 2026 year-on-year asking price changes in Konstanz and Lindau combined (-0.9% for apartments and -1.2% for houses) tell a consistent story: the lake is flat, tracking the broader stabilisation discussed in our guide to the German property market.

Methodologically, the two benchmarks measure different things. Destatis tracks completed transactions across all of Germany, whereas the CASAFARI series measures asking prices from active listings in two specific lakeside municipalities. Even so, both point to a market that has found its floor without starting a new climb.

One reason asking prices hold firm despite muted transaction activity is the cost of building replacements. Conventional residential construction prices in Germany rose by 5.0% year on year in May 2026, according to the Statistisches Bundesamt (Destatis) construction price index. High replacement costs keep new lakeside developments scarce, which supports existing stock in a way that mirrors the Munich area guide and wider property market trends across Europe.

Who is buying, and why demand holds without population growth?

Demand in Konstanz is sustained by structural shortage rather than demographic expansion. According to Konstanz population figures for 2025 (Stadt Konstanz, as of 31 December 2025), the city's main-residence population stood at 87,178, down by 190 residents (-0.2%) on 2024. The city administration explicitly cites the tight housing market as the primary reason families move out to the surrounding Umland.

Several durable factors keep the market tight across both towns:

• Cross-border purchasing power: Konstanz and its Swiss neighbour Kreuzlingen form a seamless cross-border agglomeration of about 110,000 inhabitants (Stadt Konstanz, Konstanz in Zahlen 2025). Swiss salaries and the proximity of Zürich airport—roughly an hour away—anchor demand on the German side of the border.
• University inflow: The Universität Konstanz and HTWG Konstanz bring a permanent influx of students and academic staff, keeping one- and two-bedroom apartments in short supply.
• Bavarian lakeside appeal: Lindau (Bodensee), with a population of 25,845 on 31 December 2024 (Bayerisches Landesamt für Statistik, report A1210C 202400), draws retirees and weekend buyers from Munich, Stuttgart and the Rhineland. According to the Schwäbische Zeitung (2023), Lindau counts about 520 registered second homes, generating roughly €1 million a year in municipal second-home tax.

Beyond Swiss and Austrian neighbours, international buyers remain relatively rare on the Bodensee. For a well-prepared non-resident buyer, that lack of global competition is itself an opening.

What should a buyer from abroad know before signing?

Under German property law (2026), there are no foreign-buyer restrictions, permit regimes or residency requirements. Swiss, British, Dutch or American buyers purchase on the exact same legal footing as German citizens, signing a notarised deed and registering title in the land register (Grundbuch). What requires careful calculation are the state and municipal rules.

First, real estate transfer tax (Grunderwerbsteuer) changes across the state border between the two towns. Under the transfer tax rates by Land (§ 11 GrEStG, 2026), Baden-Württemberg (Konstanz) charges 5.0% of the purchase price, whereas Bayern (Lindau) charges 3.5%. On a €600,000 purchase, that state border represents €30,000 in tax in Konstanz versus €21,000 in Lindau, before notary and Grundbuch fees.

Second, both municipalities tax secondary residences heavily through a second-home tax (Zweitwohnungssteuer):

• Konstanz: Levies 35% of the annual net cold rent (Nettokaltmiete) since 2022, under the city bylaw of 29 April 2014 (last amended 20 May 2021, rate confirmed by 2026 municipal tax tables on zweitwohnungssteuer-rechner.de). This is the highest second-home tax rate in Germany.
• Lindau: Levies 20% of the annual net cold rent since 1 January 2006, using an estimated local rent for owner-occupied second homes, as confirmed by the City of Lindau on its second-home tax (2026).

Third, short-term letting is tightly policed in Konstanz. Under the rules of the City of Konstanz on misuse of housing (Zweckentfremdung), in force since 14 March 2015, converting residential space into holiday lets or offices, or leaving a dwelling vacant for more than six months, requires an official permit. Holiday letting is tolerated for up to 10 weeks per calendar year only if notified to the city. Buyers considering Lindau for holiday letting should verify current municipal rules directly with the town hall before committing.

For buy-to-let investors examining how investors use CASAFARI data, note that CASAFARI does not yet publish a rental series for these two location ids, so no indicative average yield is stated here. Rather than relying on town-wide averages, advisers should run Comparables and market study for a specific flat or house to price individual buildings accurately.
