Tegernsee property market: prices, second-home tax and what the data really shows

In Q3 2026, the average asking price in the town of Tegernsee was €10,638.4/m² for apartments and €15,060.7/m² for houses, according to CASAFARI Area Insights (location id 529386, asking prices from indexed listings, outliers excluded). This places the town of 3,511 residents among Germany's most expensive addresses. Apartment asking prices are down 6.6% year on year while houses are up 7.4%. These figures cover the town of Tegernsee only—not Rottach-Egern, Bad Wiessee, Gmund or Kreuth—and a 20% second-home tax applies.

Picture a Munich couple on the Saturday regional train, scrolling property portals as the carriage clears the forest south of Holzkirchen. They are looking for a two-bedroom flat within walking distance of the Seepromenade. What surprises them is not that lakefront penthouses command trophy sums, but that €10,638.4/m² is the average asking price for an apartment in the town, not the top of the market.

Look a little closer at the Area Insights series behind these figures, however, and a quieter story emerges. In this small lakeside municipality, flats have gently become cheaper over the past two years, even as detached houses and villas have climbed to near-record asking levels.

What does property cost in Tegernsee in 2026?

In the third quarter of 2026, indexed listings in the town of Tegernsee asked an average of €10,638.4/m² for apartments and €15,060.7/m² for houses (CASAFARI Area Insights, location id 529386, queried 23 October 2026). To put those figures in context, buyers comparing the lake with the Bavarian capital—covered in detail in our Munich property guide—will find that a small Upper Bavarian spa town matches or exceeds prime urban neighbourhoods, while standing far above the German property market as a whole.

Scope matters when reading any number on the lake. Location id 529386 measures the municipality of Stadt Tegernsee alone, which had 3,511 residents on 31 March 2026 (BayernPortal population figure for Tegernsee, down from 3,567 on 31 December 2024 according to the Bayerisches Landesamt für Statistik). It does not include the four other municipalities that ring the water: Gmund, Bad Wiessee, Rottach-Egern and Kreuth.

Across the whole valley, the spread between an ordinary flat on a through-road and a first-line villa is vast. The Kreissparkasse Miesbach-Tegernsee market paper, summer 2026 (ImmobilienForum Landkreis Miesbach) places apartment asking prices across the Tegernsee valley between roughly €4,500/m² and €19,500/m², and houses between about €1.0m and €15m. Within a single postcode, an unobstructed lake view or private jetty can double the price of an otherwise comparable home.

Every CASAFARI figure cited on this page reflects asking prices from online listings with statistical outliers removed, not notarised transaction prices.

Are Tegernsee prices rising or falling?

The town of Tegernsee is running at two speeds. Apartment asking prices stood at €10,638.4/m² in Q3 2026 versus €11,392.0/m² in Q3 2025, a drop of 6.6% year on year, and sit 10.4% below the €11,872.1/m² recorded in Q4 2023 (CASAFARI Area Insights, location id 529386). Houses moved the other way: €15,060.7/m² in Q3 2026 compared with €14,024.1/m² in Q3 2025, up 7.4% year on year and 4.0% above Q1 2023 (€14,485.0/m²), after touching a series high of €16,041.5/m² in Q2 2026.

Because the town is tiny, the quarterly series requires a careful eye. When only a few dozen homes are on the market at any moment, the arrival or withdrawal of three or four luxury listings can move a single quarter's average by 10% to 20%. In the apartment series, Q1 2023 has no data and Q2–Q3 2023 show €15,801/m² and €17,557.7/m² on the back of very few listings; those quarters are sparse-data artefacts, not a market peak, which is why Q4 2023 (€11,872.1/m²) is the first reliable baseline. In the house series, Q3 2023 repeats the Q2 2023 figure of €13,156.0/m² because no new data entered the index that quarter.

The same caution applies to the move in house asking prices from €10,630.2/m² in Q1 2025 to €15,060.7/m² in Q3 2026 (+41.7%). In a market this thin, that swing describes the mix of houses offered in each quarter—a range, not a 40% repricing of the same brick and mortar. Always read four to six quarters together, never one in isolation.

Even allowing for listing noise, the divergence between softer flats and firmer houses mirrors the broader national picture. Across Germany, the transaction-based Destatis house price index, Q2 2026 (Statistisches Bundesamt, press release 336, published 24 September 2026) rose 0.6% year on year and 0.3% quarter on quarter. Tegernsee's detached houses have outpaced the national recovery in asking terms, while its apartments have lagged.

What sellers ask is not necessarily what buyers pay. The summer 2026 Kreissparkasse Miesbach-Tegernsee report notes that while transaction numbers are rising again, buyer decision times have lengthened. How wide the discount is between final asking price and notarised contract price cannot be stated from public portal data.

Who buys in Tegernsee, and why?

Despite its international reputation, the buyer pool in the town of Tegernsee is overwhelmingly domestic. The typical purchaser is based in Munich or elsewhere in Bavaria, often in their fifties or older—entrepreneurs, senior executives and established families acquiring a weekend residence or preparing a move for retirement. A smaller share consists of local households upsizing or downsizing within the valley.

International buyers remain a minority and are largely German-speaking households from Austria and Switzerland or expatriate Germans returning home. Unlike Kitzbühel or St. Moritz, Tegernsee has no large non-domestic investor crowd, a quietness that is precisely what draws discreet family offices and private buyers to the eastern shore.

Four practical forces hold demand in place:

• Scarcity by geography and law: Hemmed in between the water and the Alpine foothills near the Wallberg, much of the town and valley sits inside a protected landscape area (Landschaftsschutzgebiet). New construction is limited to small infill plots or the replacement of existing stock.
• Town infrastructure: Although the town of Tegernsee counts only 3,511 residents, its status as a traditional spa town and home to the former Benedictine abbey and its Bräustüberl supports medical services, gastronomy and retail far beyond a normal village of its size.
• Capital preservation: Buyers treat lakeside real estate primarily as a long-term store of wealth rather than an income-producing asset.
• Distinct micro-segments: Town-centre and Seepromenade apartments serve second-home buyers seeking lock-up-and-leave convenience, whereas detached houses and villas with lake views or water access form a trophy market where many sales happen off-market.

Because pure rental yield is rarely the motive—purchase prices are high relative to achievable local rents, and municipal policy discourages idle holiday flats—institutional and private buyers evaluating what CASAFARI offers investors focus here on capital preservation and replacement cost. And because the best lakeside houses rarely sit on a single public portal, advisers rely on Property Sourcing across portals and off-market listings to see the whole inventory.

What taxes and rules apply to a second home in Tegernsee?

Anyone buying a property in the town of Tegernsee that will not serve as their registered main residence (Hauptwohnsitz) faces a substantial annual holding tax alongside standard German purchase costs.

Under the town of Tegernsee's second-home tax bylaw (Zweitwohnungsteuersatzung, in force since 1 January 2018 and unchanged as of July 2026), the municipality levies a second-home tax (Zweitwohnungsteuer) equal to 20% of the property's annual net cold rent (Nettokaltmiete). Where a second home is owner-occupied rather than rented, the town assesses the tax using a local comparable rent. The four neighbouring valley municipalities—Gmund, Bad Wiessee, Rottach-Egern and Kreuth—apply the same 20% rate.

In practical terms, an apartment assessed at a notional net cold rent of €1,500 a month (€18,000 a year) carries an annual second-home tax bill of €3,600. Moreover, the rate may not stay at 20% indefinitely: according to an Abendzeitung report on the mayor's tax proposal, February 2026 (published 25 February 2026), First Mayor Johannes Hagn stated that the town has a particularly high number of second residences and proposed raising the tax again to curb them, though no higher rate had been confirmed as adopted by mid-2026.

On the acquisition side, rules are more straightforward:

• Real estate transfer tax (Grunderwerbsteuer): Bavaria charges 3.5% of the notarised purchase price under § 11 of the federal Grunderwerbsteuergesetz (GrEStG as of October 2026), the lowest rate of any German federal state. Notary and land-registry (Grundbuch) fees add roughly 1.5% to 2.0%, and estate agent commission on residential sales is typically split between buyer and seller under Germany's 2020 brokerage law.
• Foreign ownership: German law places no restrictions on foreign buyers. Both EU and non-EU nationals may purchase residential property in Tegernsee without a special permit or residency status, subject to standard anti-money-laundering and identity checks at the notary.
• Planning, energy and letting rules: Rebuilding or extending an older villa is constrained by the Landschaftsschutzgebiet, strict shoreline water-protection rules, and federal Building Energy Act (Gebäudeenergiegesetz, GEG) retrofit obligations. Buyers who hope to offset costs through occasional holiday letting must inquire directly at the Tegernsee Rathaus before signing, as municipal rules on short-term tourist use and housing protection vary across the valley.

What are the risks of buying at Tegernsee?

A clear-eyed buyer or family office adviser weighs five structural risks before committing capital in the town of Tegernsee:

1. Thin liquidity at the top end: Between €2m and €15m for a house (Kreissparkasse Miesbach-Tegernsee, summer 2026), the pool of qualified buyers in any given quarter is small. Reselling a high-value property—especially one without a direct lake view—can easily take a year or longer.
2. Political headwinds against second homes: The municipal council openly wishes to protect housing for year-round residents. A future increase in the 20% second-home tax (Abendzeitung München, 25 February 2026) or tighter municipal use bylaws remain live possibilities.
3. Asking-to-achieved price gaps: In a selective market where buyers take longer to commit, ambitious portal asking prices can sit well above actual clearing prices.
4. Financing sensitivity in the mid-market: While trophy lakeside villas often change hands for cash, the Kreissparkasse Miesbach-Tegernsee summer 2026 report notes that mortgage costs well above 2021 levels still weigh on buyers in the middle of the market.
5. Renovation and environmental compliance: Older post-war houses face costly energy upgrades under the GEG alongside tight local limits on plot coverage and shoreline alteration.

How to check a Tegernsee asking price before you offer

Because a single panoramic terrace can separate a €10,600/m² flat from a €19,000/m² one, benchmarking an asking price against the town average is only the first step. Before submitting an offer, buyers and their agents should check a specific property with Comparables and a market study to isolate current and historical listings on the same slope, street and micro-location.

Suppose you are offered a 110 m² apartment near the water at €14,000/m² (€1.54m). That is 31.6% above the Q3 2026 town of Tegernsee average of €10,638.4/m² (CASAFARI Area Insights, location id 529386), yet well inside the €4,500–€19,500/m² valley spread reported by the Kreissparkasse in summer 2026. By pulling line-by-line comparables—filtering for lake view, building age, condition and exact days on market—you can see immediately whether €14,000/m² reflects recent competing supply or a seller testing yesterday's market.

If your search spans the whole lake rather than the town of Tegernsee alone, remember that location id 529386 stops at the town boundary. Analysts and proptech teams building automated valuation models can resolve the neighbouring municipalities—Rottach-Egern, Bad Wiessee, Gmund and Kreuth—via Location Lookup and query each time series through the Area Insights documentation on developers.casafari.com and the Comparables and valuation API documentation.
