SUMMARY
Vienna Altbau apartments are not broadly becoming cheaper to buy today. They repriced after the 2022 peak, but stronger old-building apartments are rising again, leaving the best discounts in properties with specific problems rather than across the market as a whole.
The big distinction is between being cheaper than the previous peak and still getting cheaper. Vienna residential prices fell in 2023 and 2024, yet the latest OeNB, transaction and asking-price data all point toward recovery rather than another broad leg down.
Inflation makes the earlier correction look larger. Plenty of Altbau remains cheaper in real purchasing-power terms than during the boom even where nominal prices have recovered substantially.
Good Altbau is behaving differently from weak Altbau. Renovated apartments in desirable Gründerzeit locations can once again approach new-build pricing, while untouched units, buildings without lifts and properties facing heating or common-area work can still carry large discounts.
The cheapest-looking apartment is often not the cheapest one after renovation. At roughly €1,500-€2,000 per square metre for a solid refurbishment, a 70-square-metre Altbau can absorb €105,000-€140,000 before major building-level costs are considered.
Location creates an enormous spread. Comparable pre-1961 apartments can sit near €3,000 per square metre in Favoriten or Simmering and well above €5,000 in the most desirable inner Altbau districts, so there is no useful single “Vienna Altbau price.”
Altbau is usually cheaper than post-1991 housing, but it is not necessarily Vienna's cheapest stock. In several central districts, buyers actually pay more for pre-1961 apartments than for ordinary 1961-1990 housing because desirable Gründerzeit features carry their own premium.
Rent regulation creates another market entirely. An occupied pre-war apartment subject to restrictive rent rules can be worth far less to an investor than an otherwise similar vacant unit sold to an owner-occupier.
This also explains the strange gap between Zinshäuser and the apartments inside them. Whole buildings absorb financing, tenancy, regulation and restructuring risk, while an individual vacant Altbau can trade on lifestyle appeal and owner-occupier demand.
The practical opportunity has shifted. During the correction, buyers could negotiate against a weak market; today the better strategy is to find a solvable problem that the asking price discounts too heavily — ugly interiors, an estate sale or manageable renovation — while avoiding underfunded buildings and unresolved structural costs.
Why does Vienna Altbau suddenly look cheaper?
Vienna Altbau really did get cheaper after the 2022 property peak, but today the broad correction looks largely finished.
The change started with financing. Mortgage rates jumped, buyers lost borrowing power and Vienna's property market slowed sharply. OeNB's residential-property index shows Vienna prices falling 2.3% in 2023 and another 3.4% in 2024. Entire Zinshäuser, which are heavily exposed to financing costs and regulated rents, were hit even harder.
That created opportunities buyers had barely seen during the low-rate years. Sellers became more flexible, transaction volumes dropped and apartments with renovation needs could sit on the market for much longer.
The latest evidence points somewhere different. OeNB's published series had Vienna residential prices up 2.3% year on year in Q1 2026. ImmoScout24's analysis of roughly 186,500 listings then found Vienna apartment asking prices at €6,729 per square metre in the first half of 2026, 2% above the previous year. EHL's 2026 Zinshaus report goes further for Altbau specifically: it says good old-building condominiums are once again approaching record prices.
So there was a real repricing. Buyers looking today are arriving after much of it has already happened.

Are Vienna Altbau apartment prices still falling today?
No. Vienna Altbau prices are currently rising in the stronger parts of the market, while cheaper deals are concentrated in individual apartments with specific problems.
The latest OeNB data available today show Vienna residential prices already growing again. ImmoScout24 reaches the same conclusion from listings: Vienna apartment asking prices increased 2% in the first half of 2026.
The strongest Altbau-specific evidence comes from EHL's 2026 research. EHL says prices for existing condominiums have recently risen faster than new-build prices in some parts of Vienna, with high-quality renovated Altbau in very good locations getting close to comparable new-build values. It also describes old-building apartments in strong Gründerzeit locations as approaching new highs.
That doesn't mean every Altbau is getting more expensive. A fourth-floor apartment without a lift, an untouched unit with a gas boiler or a building facing major roof and façade work can still need a serious discount. But those discounts now tell us more about the property than about Vienna's overall direction.
Avoid the mistakes other buyers made in Vienna
Real buyers explain what went wrong, what they missed and what they wish they had checked earlier. Read their mistakes before you make the same ones.
Are Vienna Altbau apartments still cheaper than at the 2022 peak?
Yes. Many Vienna Altbau apartments are still cheaper than around the 2022 peak, and the decline is much larger once inflation is taken into account.
OeNB recorded consecutive Vienna price declines in 2023 and 2024 before the recovery started. Even after prices began moving upward again, that initial loss was not instantly recovered.
Inflation widened the difference. Austrian consumer prices rose sharply over the same period, so a Vienna apartment selling for roughly its old nominal price today represents a considerably lower real price than it did several years ago.
This explains why buyers can hear two apparently conflicting stories. A seller may reasonably say Vienna prices are rising again today, while a buyer can also correctly say that property remains cheaper in real terms than near the boom.
For someone deciding whether to buy now, the first point matters more. The peak-to-trough discount already exists in today's price. Waiting only makes sense if we expect a second broad correction, and the latest evidence gives us little reason to expect one right now.
Are Vienna sellers still accepting much less than their asking price?
Some are, but completed transactions now show a recovering Vienna apartment market rather than a hidden second leg down.
Asking prices can mislead during a correction because owners often reduce their expectations slowly. Land-registry transactions are more useful for checking whether buyers are actually paying less.
RE/MAX and IMMOunited analysed the completed Vienna apartment transactions registered in the Austrian land register during 2025. They counted 11,915 sales, up 24.7% from 2024. The average purchase price rose 3.9% to €316,157, while the recorded price per square metre increased 6.5% to €5,512.
That square-metre increase should be treated cautiously because the mix of apartments sold changes from year to year. District results were extremely uneven: Mariahilf fell 11.8% per square metre while Leopoldstadt jumped 26.5%. Those moves clearly include changes in what was sold.
The transaction count is harder to dismiss. Vienna moved from fewer than 10,000 apartment sales in 2024 to nearly 12,000 a year later. Sellers facing several interested buyers have less reason to take a weak offer than they did near the bottom of the market.
| Vienna apartment transactions | 2025 | Change from 2024 |
|---|---|---|
| Completed sales | 11,915 | +24.7% |
| Average purchase price | €316,157 | +3.9% |
| Average recorded price per m² | €5,512 | +6.5% |
| Total transaction value | €4.19bn | +30.0% |
Before you sign the Kaufanbot, read what buyers learned
The details that feel routine at this stage are often where buyers get caught. See the real cases, the paperwork they trusted and what they should have checked first.
Is Vienna Altbau actually cheaper than newer apartments?
Usually yes. Classic Vienna Altbau generally sells below apartments built after 1991, although it often costs more than ordinary post-war housing.
Statistics Austria's transaction data make the difference unusually clear. For apartments between 54 and 77 square metres without a balcony, terrace or garden, homes built up to 1960 are cheaper than post-1991 apartments in 22 of Vienna's 23 districts.
The size of that gap varies considerably. In Leopoldstadt, the older-stock benchmark is €4,630 per square metre versus €6,369 for post-1991 housing, a difference of about 38%. In Währing, the gap is roughly 28%. In Wieden it is about 32%.
Altbau looks much less cheap when we compare it with 1961-1990 housing. In many central districts, buyers actually pay more for the oldest category. Alsergrund's benchmark is €5,549 per square metre for pre-1961 housing versus €4,750 for 1961-1990 apartments. Mariahilf shows €5,445 versus €4,743.
Buyers clearly attach a premium to the things a good Gründerzeit apartment offers: ceiling height, large windows, historic façades, generous rooms and central streets. The really cheap Vienna housing stock is often post-war housing rather than Altbau.
| District | Up to 1960 | 1961-1990 | 1991 onward | Newer-stock premium over pre-1961 |
|---|---|---|---|---|
| Leopoldstadt | €4,630/m² | €4,603/m² | €6,369/m² | 38% |
| Landstraße | €4,814/m² | €4,538/m² | €5,655/m² | 17% |
| Wieden | €5,397/m² | €4,921/m² | €7,139/m² | 32% |
| Mariahilf | €5,445/m² | €4,743/m² | €4,708/m² | -14% |
| Neubau | €5,110/m² | €4,849/m² | €6,214/m² | 22% |
| Josefstadt | €5,797/m² | €5,227/m² | €6,343/m² | 9% |
| Alsergrund | €5,549/m² | €4,750/m² | €6,404/m² | 15% |
| Währing | €4,470/m² | €4,556/m² | €5,735/m² | 28% |
Is the Altbau discount to Vienna new builds getting bigger?
No. The price gap between good Vienna Altbau and new apartments has actually been shrinking in the locations where old housing is most desirable.
EHL was already seeing this in its 2025 Zinshaus research, and its newer 2026 report makes the point even more strongly. High-quality renovated Altbau in prime Gründerzeit and inner-city locations is increasingly reaching prices close to comparable new construction.
Scarcity explains a lot of it. Buyers looking inside the Gürtel or in established western districts have very few new projects to choose from. New construction increasingly sits in large development areas farther out, particularly in Floridsdorf and Donaustadt.
A buyer who specifically wants Neubau, Josefstadt or Alsergrund therefore has limited substitutes. Once an Altbau has a lift, modern heating, renovated common areas, a good floor plan and perhaps a balcony or terrace, its age stops creating much of a discount.
EHL's latest report says the strongest renovated Altbau can now approach new highs. The idea of an ever-widening Altbau discount is getting pretty difficult to defend.
What Austrian property buyers wish they had checked earlier
Locals know which questions are normal and which red flags matter. We collected the problems buyers actually ran into, not generic advice.
Are renovated Vienna Altbau apartments getting cheaper?
No. Properly renovated Vienna Altbau apartments in good locations are among the parts of the old-housing market holding up best today.
The buyer pool for these apartments is easy to understand. People get the high ceilings, old parquet, large windows and central streets associated with Gründerzeit housing without taking on the full inconvenience of a neglected nineteenth-century building.
Creating that combination has also become expensive. Renovating an old apartment requires tradespeople, materials, electrical work, plumbing and often coordination with the whole building. EHL's newest Altbau research puts a solid apartment renovation at roughly €1,500-€2,000 per square metre, with higher-spec work starting above €2,000.
For a 70-square-metre apartment, that means roughly €105,000-€140,000 before we even reach the more ambitious end of the market.
That cost gives completed renovations a much clearer value than a few years ago. A vacant, renovated Altbau with good common areas and solved heating can attract owner-occupiers who would otherwise look at expensive new construction.
The easy Altbau bargains tend to appear before renovation rather than after it.
Are unrenovated Vienna Altbau apartments still bargains?
Sometimes. Unrenovated Vienna Altbau is where we still find some of the biggest discounts, but €1,500-€2,000 per square metre of renovation work can wipe out a cheap-looking purchase remarkably fast.
Take a 70-square-metre apartment. At EHL's current renovation range, a solid refurbishment already implies roughly €105,000-€140,000. A high-end job can go above that.
The apartment itself is only half the risk. We also check the owners' association, reserve fund, roof, façade, windows, lift and heating system. A buyer can renovate an interior beautifully and still receive a large building-level bill later.
Gas deserves particular attention in Vienna Altbau. The City of Vienna plans to move space heating and hot water away from fossil fuels by 2040. Its programme covers heating systems serving roughly 600,000 households, with district heating, heat pumps, geothermal solutions and local networks all expected to play a role.
The timing and cost will vary by building, and subsidies can change the calculation. Still, an Altbau already connected to district heating sits in a better position than an otherwise identical building where owners have barely begun discussing how to replace individual gas boilers.
We would therefore want a much larger purchase discount for an untouched apartment in an underfunded building than for one that simply needs a new kitchen and floors.

We sorted real buyer mistakes by the moment they happen, from first checks and offers to contracts, money transfers and the keys.
Where is Vienna Altbau still cheapest to buy?
Favoriten, Simmering, Floridsdorf, Liesing and parts of Ottakring remain much cheaper than Vienna's classic central Altbau districts.
Statistics Austria's latest transaction tables allow a fairly clean comparison by using apartments of 54-77 square metres without outdoor space and separating them by construction period.
For housing built up to 1960, Favoriten sits at €3,024 per square metre and Simmering at €3,048. Floridsdorf is €3,169, Liesing €3,251 and Ottakring €3,551.
Move into the traditional inner Altbau belt and prices jump. Wieden reaches €5,397 per square metre, Mariahilf €5,445, Alsergrund €5,549 and Josefstadt €5,797. The Inner City is in another category at €7,077.
For a 70-square-metre apartment, the gap between €3,024 and €5,797 per square metre is about €194,000 before transaction costs. That's large enough that talking about one “Vienna Altbau price” becomes almost meaningless.
Ottakring and Rudolfsheim-Fünfhaus are particularly interesting for buyers who want genuine urban Gründerzeit stock without paying inner-district prices. They still offer many proper Altbau streets, unlike some cheaper outer districts where pre-war stock is much less central to the housing market.
| District | Pre-1961 benchmark | Approx. value for 70 m² |
|---|---|---|
| Favoriten | €3,024/m² | €211,680 |
| Simmering | €3,048/m² | €213,360 |
| Floridsdorf | €3,169/m² | €221,830 |
| Liesing | €3,251/m² | €227,570 |
| Ottakring | €3,551/m² | €248,570 |
| Rudolfsheim-Fünfhaus | €3,763/m² | €263,410 |
| Landstraße | €4,814/m² | €336,980 |
| Neubau | €5,110/m² | €357,700 |
| Alsergrund | €5,549/m² | €388,430 |
| Josefstadt | €5,797/m² | €405,790 |
Have Neubau, Mariahilf and Vienna's fashionable Altbau districts become cheaper?
Some have. Mariahilf and Neubau still showed price declines in 2025 transactions, while several neighbouring Altbau districts were already rising strongly.
RE/MAX's land-registry data capture how messy the recovery has been. Mariahilf's recorded apartment price per square metre fell 11.8% in 2025 and Neubau fell 3.1%. Margareten was down 2.7%.
A few streets away, the direction was completely different. Alsergrund rose 8.8%, Währing 10.7%, Josefstadt 13.5% and Landstraße 12.5%.
These district changes are too large to read as pure house-price indices because the mix of homes sold matters enormously. Only 142 apartments changed hands in Josefstadt, for example. A larger share of renovated or better-located units can move the average quickly.
Still, Mariahilf and Neubau deserve attention precisely because they combine desirable Altbau stock with recent price softness. They offer a more credible hunting ground for buyers than assuming every central district is equally discounted.
Today's broader market is already recovering. A soft micro-market inside that recovery is more interesting than simply buying wherever prices are rising fastest.
The traps foreign buyers keep discovering in Austria
Foreign buyers use different agents, documents and assumptions. See the problems that show up when you do not know the local shortcuts yet.
Is Vienna rent regulation making some Altbau apartments much cheaper?
Yes. Vienna's rental rules can push the investment value of certain Altbau apartments far below what an owner-occupier would pay for a comparable vacant unit.
The distinction is crucial for pre-war housing. Under Austria's Mietrechtsgesetz, many rented apartments in buildings constructed before 9 May 1945 fall under the full MRG regime, subject to the building and tenancy details. Rent-setting rules can therefore restrict the income a landlord can generate.
Meanwhile, freely priced Vienna rents have risen sharply. The wider the gap between regulated rent and open-market rent becomes, the less attractive the regulated unit looks to an investor.
This pressure is changing what landlords do with Altbau. EHL's 2026 Zinshaus report says state intervention in existing tenancies has encouraged some investors and landlords to withdraw. At the same time, the spread between whole-building values and the prices obtainable from individually sold apartments has become unusually wide.
That makes condominiumisation and individual sales attractive. A landlord may struggle to justify holding a regulated rental indefinitely, while a vacant apartment can be sold to someone who simply wants to live there.
Vacancy status can therefore change the value of the same physical apartment dramatically. For buyers, an unusually cheap occupied Altbau deserves legal due diligence before celebrating the discount.
Why are whole Vienna Zinshäuser so much cheaper than the apartments inside them?
Because whole Vienna Zinshäuser currently carry financing, regulation and tenancy risks that individual owner-occupied Altbau apartments largely escape.
EHL's 2026 research finds an unusually wide split between these two markets. Even largely vacant Zinshäuser can currently trade at square-metre values up to 30% below what the individual apartments inside the same building may achieve when sold separately.
That gap tells us something important about Altbau pricing. A whole building is valued through expected rental income, financing conditions, renovation costs and the difficulty of clearing or restructuring existing leases. Banks also demand more equity and scrutinise Zinshaus financing more closely than they did during the boom.
An individual apartment reaches a completely different buyer. Someone purchasing a renovated three-room flat in Neubau for personal use cares about the street, ceiling height, light, layout and whether there is a lift. The legal yield on the building's other apartments matters much less.
This explains why headlines about falling Vienna Zinshaus prices can be misleading for someone trying to buy one Altbau apartment. The building market has repriced much more heavily than the owner-occupier apartment market.
It also explains why developers are interested again. Buying an entire building at today's weaker Zinshaus valuation, dividing it into condominium ownership and selling the units one by one can create a large price spread before renovation and financing costs.
What Austrian owners say catches buyers off guard
Owners talk about the defects, fees, clauses and promises that looked harmless before the deal. Their stories show where to slow down.
Have lower mortgage rates made Vienna Altbau affordable again?
Vienna Altbau has become easier to finance than during the worst of the rate shock, but mortgage costs are still far above the low-rate years.
That difference helps explain why buyers have returned without recreating the old boom.
Imagine financing €300,000 over 30 years. At 4.65%, a rough monthly principal-and-interest payment is about €1,550. At 3.4%, it falls to around €1,330. That is roughly €220 a month back in the buyer's budget.
The comparison with the old cheap-money era is much less comfortable. At 1.5%, the same loan costs roughly €1,035 a month. Today's 3.4% example still leaves the buyer paying around €295 more every month.
For a €400,000 loan, that rate difference becomes much more painful. This is one reason Vienna apartment prices have recovered gradually instead of exploding back toward the previous trajectory.
Lower rates have removed some of the forced-price pressure on sellers. They have not restored the extraordinary affordability of debt that helped create the previous peak.
| €300,000 mortgage over 30 years | Approx. monthly payment |
|---|---|
| 1.5% | €1,035 |
| 3.0% | €1,265 |
| 3.4% | €1,330 |
| 3.6% | €1,364 |
| 4.65% | €1,550 |
Can Vienna Altbau buyers still negotiate hard today?
Yes on flawed properties, much less on good ones. Vienna buyers currently have negotiating power when they can point to a specific cost or defect rather than simply arguing that the property market is weak.
The demand numbers have moved against buyers. ImmoScout24 found interest in Vienna condominiums rising 21% during 2025, after demand had already strengthened the previous year. RE/MAX then recorded 24.7% more completed Vienna apartment sales.
More recent listing data add another detail: the number of apartments offered for sale across Austria increased 10% in the first half of 2026 while prices still rose. Buyers have more stock to browse, but the extra supply has not forced sellers into broad price cuts.
Negotiation works best where the problem can be priced. No lift, individual gas heating, a weak reserve fund, pending façade work, a dark ground floor, an awkward layout or €100,000 of renovation creates a concrete argument.
A renovated Altbau in a sought-after street with solved heating, a lift and no obvious building liabilities is a different fight. Those properties can now attract several buyers again.
The useful question at a viewing these days is simple: what expensive problem does this asking price fail to reflect?
Don't discover after signing what other buyers learned too late
Some of the most expensive property mistakes look obvious only afterwards. Read the cases before the contract makes them your problem.
Will Vienna's shortage of new apartments push Altbau prices higher?
Probably. Vienna's collapsing new-build pipeline is already giving good Altbau less competition, especially in central districts.
EHL's latest housing-market update says fewer than 10,000 apartments were completed in Vienna in 2025 for the first time in almost a decade. It projects only about 8,630 completions in 2026.
The ownership segment is tightening as well. EHL expects roughly 3,738 newly completed owner-occupied apartments in 2026, around 1,000 fewer than the previous year. New development is increasingly concentrated in larger outer districts, especially the 21st and 22nd.
The effect becomes much stronger inside established Gründerzeit neighbourhoods. A buyer who wants to live around Neubau, Josefstadt, Wieden, Alsergrund or the western inner districts cannot simply choose from thousands of new apartments nearby.
Good renovated Altbau fills that gap naturally. EHL already sees high-quality old-building condominiums in strong locations moving closer to new-build pricing.
If Vienna construction remains this weak while purchase demand continues recovering, desirable Altbau should become harder rather than easier to buy cheaply.
What does a genuinely cheap Vienna Altbau apartment look like now?
A genuinely cheap Vienna Altbau today needs to be discounted after we account for the district, condition, heating, legal status and building-level costs.
District averages give us a useful first check. A pre-1961 apartment around €3,500 per square metre in Ottakring is close to the official benchmark there, so the price alone tells us very little. At €3,000 with decent light, healthy reserves and no major works ahead, the conversation becomes more interesting.
The same logic applies in Alsergrund. Statistics Austria puts the comparable older-stock benchmark around €5,549 per square metre. A renovated apartment at €5,600 may actually be good value if the building has a lift, modern heating and strong common areas. An untouched apartment at the same price clearly isn't.
Renovation has to be added before comparing alternatives. At €1,500-€2,000 per square metre, improving a 70-square-metre unit can easily cost €105,000-€140,000. Building works can push the effective cost higher again.
We would pay particular attention to apartments where the market has overreacted to something fixable: ugly interiors, an estate sale, poor listing photos, a seller needing liquidity or a manageable renovation. Structural problems such as weak reserves, unresolved heating conversion and major common-area works deserve a much larger discount.
The best Altbau deals currently come from buying a solvable problem cheaply, rather than buying the cheapest apartment we can find.
What agents and sellers may not warn you about
The person selling the property is there to close the deal. See the checks, clauses and problems buyers say they had to discover for themselves.
Are Vienna Altbau apartments becoming cheaper to buy?
Partly true, but mostly as a description of what has already happened. Vienna Altbau repriced after the 2022 peak, while good old apartments are currently moving upward again.
The correction was meaningful. Vienna residential prices fell in both 2023 and 2024, financing became much more expensive and some central districts continued to show lower transaction prices during 2025. Inflation made the real decline larger again.
Today's evidence has changed direction. OeNB's latest published Vienna reading is positive. ImmoScout24 finds Vienna asking prices 2% higher in the first half of 2026. Completed apartment sales jumped nearly 25% in 2025. EHL now says good Altbau condominiums in strong Gründerzeit locations are approaching new highs, while Vienna's new-build pipeline is shrinking sharply.
The remaining discounts are concentrated. Unrenovated apartments, gas-heavy buildings, weak owners' associations, regulated tenancies and less fashionable locations can still look much cheaper than they did during the boom. Good renovated Altbau in central Vienna increasingly cannot.
So if we compare today's purchase price with the top of the previous cycle, many Vienna Altbau apartments are indeed cheaper, especially after inflation.
If we are asking whether Vienna Altbau is still becoming cheaper right now, the answer is no.
The broad repricing has already happened. The opportunity now sits in individual apartments where the market is still charging too large a discount for a problem we can actually solve.
OUR METHODOLOGY
We approached this question by breaking it into the market signals that can actually tell us whether Vienna Altbau is becoming cheaper, rather than relying on general impressions about Vienna property prices.
First, we separated what has happened since the 2022 peak from what is happening today. A property can still be cheaper than it was at the top of the cycle while already rising again, so we looked at both the cumulative repricing and the latest direction of travel, including inflation where it materially changes the comparison.
We then tested the market from several angles. Broad residential indices establish the direction of Vienna prices; asking-price data show where current seller expectations are moving; completed transactions show what buyers are actually paying; and Altbau- and Zinshaus-specific research helps isolate what is happening inside older housing.
Where official statistics do not use “Altbau” as a standalone category, we used the closest consistent construction-period groups available and kept those statistical categories separate from legal definitions. For district comparisons, we prioritized like-for-like groups, including similar apartment sizes and units without outdoor space where the data allowed it.
We treated unusually large district price movements carefully. A yearly district average can move sharply simply because the mix of apartments sold changes, especially where transaction counts are small. District figures therefore help identify relative strength or softness, but broader indices, transaction volumes and multiple independent datasets carry more weight in the overall judgment.
For unrenovated Altbau, we did not treat the purchase price as the real cost. We added likely renovation requirements and considered building-level liabilities including reserves, roof and façade work, lifts and heating conversion. That separates apartments that merely look cheap from apartments that remain attractive after the obvious costs are included.
We treated the Zinshaus market as related but distinct. Whole buildings are priced through financing, rent regulation, tenancy structures and investment yields, while an individual vacant apartment can be priced mainly through owner-occupier demand. The divergence between those markets helps explain where some Altbau discounts come from, but it is not a substitute for apartment-level pricing.
Finally, we gave the greatest weight to recent signals that agreed across independent datasets. No single statistic determines the conclusion. We looked at whether prices, transactions, demand, financing, renovation economics, regulation and new housing supply were pointing in the same direction before deciding whether the correction was continuing or had largely already happened.
Key sources used for this analysis include Oesterreichische Nationalbank's Residential Property Price Index, OeNB financial and housing-loan statistics, Statistics Austria's Immobilien-Durchschnittspreise, Statistics Austria's 2025 real-estate price release, Statistics Austria's Consumer Price Index, RE/MAX and IMMOunited's 2025 Eigentumswohnungsmarkt analysis, ImmoScout24's H1 2026 property-price analysis, ImmoScout24's 2025 condominium demand analysis, and ImmoScout24's Vienna H1 2025 analysis.
Altbau and supply-specific sources include EHL's Zinshausmarktbericht 2026, EHL's Zinshausmarktbericht 2025, EHL's Wiener Wohnungsmarkt Marktupdate Q1 2026, EHL's Wiener Wohnungsmarkt Marktupdate H1 2026, and EHL's Erster Wiener Wohnungsmarktbericht 2026. For heating and legal context, we used the City of Vienna's Raus aus Gas programme and Wärme und Kälte 2040 strategy, the Austrian Legal Information System's consolidated Mietrechtsgesetz, and Statistics Austria's Wohnen 2025 for housing-stock context.
