Is Neubau or Altbau the better buy in Vienna now?

Altbau is currently the better-value purchase for most Vienna owner-occupiers, while a well-bought, freely rentable Neubau is usually the stronger choice for a conventional landlord.

That split has become clearer as Vienna’s housing market has started moving again. OTTO Immobilien recorded €1.62 billion of condominium transactions in the first half of 2026, 21% more than a year earlier, while the number of sales rose from 3,644 to 4,290. Existing apartment prices increased to €4,645/m².

At the same time, new supply keeps shrinking. EHL counted 15,340 completed apartments in 2022, 14,253 in 2023 and 11,278 in 2024. Its latest pipeline work points to roughly 8,000 completions this year and around 7,500 the following year. OTTO reaches the same broad conclusion from a different project database and expects commercially developed rental apartments to account for only about 3% of Vienna completions in 2027.

Buyers are coming back before construction has recovered. That makes good existing apartments harder to replace, while freely rentable modern stock is getting scarcer.

For someone planning to live in the apartment for ten years or more, we would usually take a technically sound Altbau at a substantial discount to equivalent Neubau. For a landlord, Vienna’s rental law often pushes us the other way.

What does “Altbau” actually mean when buying an apartment in Vienna?

For a Vienna property investor, “Altbau” can describe the architecture, but the legally important question is when the building and apartment were created.

A Gründerzeit apartment with parquet floors, double doors and 3.3-metre ceilings may look like the classic Altbau, yet the rental rules depend on its legal history.

For many rented apartments in multi-unit buildings, construction under a permit issued before 1 July 1953 can bring the property within the full application of Austria’s Mietrechtsgesetz. For condominium units, a building erected under a permit before 9 May 1945 is particularly relevant. Exceptions exist, which is exactly why investors need the actual documents rather than the estate agent’s label.

Once the full MRG applies, the landlord may face the Richtwert system. Vienna’s current basic Richtwert is €6.74/m² per month before legally permitted additions and deductions. Location, condition and apartment features can lift the final permitted rent, sometimes significantly, but the landlord cannot simply copy the asking rent of a modern apartment across the street.

A privately financed apartment in a building permitted after June 1953 generally sits in a much freer rental regime. Some later-created apartments inside old buildings also get different treatment. A post-2001 attic conversion, for example, can fall under partial rather than full MRG application.

So when we assess an Altbau investment, we want the original building permit, the apartment’s creation history, the condominium documents and any subsidy history before we care about the ceiling rosettes.

Is Vienna’s Neubau premium too high right now?

Yes. Vienna’s current Neubau premium is large enough that buyers should demand much more than a new kitchen and fresh paint for the extra money.

OTTO’s latest transaction data put first-occupancy apartments at an average €7,395/m², compared with €4,645/m² for existing apartments. That is roughly a 59% citywide premium.

For a 70 m² apartment, those averages imply about €518,000 for first occupancy against roughly €325,000 for existing stock. The difference is around €193,000 before transaction costs.

Those are not identical homes. Neubau stock contains more terraces, lifts, efficient heating systems and modern layouts, while the resale pool includes weak locations and apartments needing work. The raw 59% gap therefore overstates the premium for two genuinely comparable properties.

Even after making that adjustment, the gap remains large. If an excellent Altbau needs €60,000 of renovation but still costs €120,000 less than the nearby Neubau, the buyer has a lot of room to improve the older apartment.

We would pay a big Neubau premium when it buys something difficult to reproduce: a proper terrace, barrier-free access, excellent summer comfort, efficient communal heating, very low near-term building costs or an unusually scarce new project in an established neighborhood. Paying €2,000 or €3,000 extra per square metre just because nobody has lived there yet is much harder to defend today.

Illustrative 70 m² purchase	Existing apartment	First occupancy	Difference
Average transaction price per m²	€4,645	€7,395	€2,750
Purchase price	€325,150	€517,650	€192,500
Relative premium	—	—	about 59%
Main trade-off	renovation and building risk	lower technical risk	buyer pays heavily for certainty
Our view	better value if technically sound	worth it only when the product is genuinely better	selective Altbau has more margin for error

What are you actually getting for the Neubau premium in Vienna?

Vienna Neubau does give buyers real advantages, especially lower building risk, better energy performance and a home designed around how people live today.

A recent building is less likely to need a roof replacement, façade overhaul, new risers, lift modernization or a complete heating conversion soon after purchase.

Modern apartments are also more likely to have lifts, step-free entrances, balconies, bicycle rooms, underground parking, better glazing and layouts designed around modern bathrooms and kitchens. Vienna’s planning rules increasingly push new buildings toward district heating, heat pumps and other low-carbon systems.

A good Vienna Altbau can still offer ceiling height, room proportions, mature streets and architectural character that developers cannot recreate at scale.

The practical question is what would be difficult or expensive to reproduce in the cheaper apartment. If the answer is “almost nothing,” the Neubau premium is probably too high.

Are cheap Vienna Altbau apartments hiding expensive building problems?

Sometimes. This is where a superficially cheap Altbau can become a very bad buy.

In a condominium building, every owner has exposure to the roof, façade, stairwell, lift, pipes, electrical infrastructure, courtyard and heating system.

Austria requires condominium buildings to maintain a repair reserve, and the statutory minimum contribution has risen to €1.12 per square metre of total usable building area per month. That minimum gives us little comfort in a 120-year-old property if the reserve has been chronically underfunded.

Imagine a building with €120,000 sitting in the reserve while the owners already know that the façade, roof and vertical pipes will require €450,000 of work. Part of the apparent purchase discount belongs to those future invoices.

Vienna approved thermal-energy renovation subsidies for 128 residential buildings in 2025, covering eligible works worth roughly €196 million. That works out to well over €1 million of eligible work per building on average, although the projects vary enormously in size.

We therefore read several years of owners’ meeting minutes, check the reserve balance and look for planned special assessments or engineering reports. A well-maintained 1895 building can be safer than a poorly managed property from the 1980s.

Does Vienna’s rent law make Altbau a bad rental investment?

For many ordinary buy-to-let investors, Vienna’s rent law is the biggest weakness of a conventional Altbau.

The current Vienna Richtwert starts at €6.74/m² before legally allowed additions and deductions. The eventual permissible rent can be considerably higher depending on location and apartment characteristics, but the landlord is still working inside a regulated formula.

Modern private rents are living in a different market. EHL’s latest investment-apartment research shows average net rents rising from €14.87/m² to €16.20/m², an 8.6% increase, while average selling prices rose about 6%. Good outer-district units are achieving around €14.50/m², and stronger central first-occupancy apartments can command far more.

That gap is more painful because rental supply is tight. EHL describes low vacancy, quick re-letting and higher rents when apartments come back onto the market. A freely rentable apartment can capture those increases much more directly.

Regulated rents are also being smoothed politically. Vienna’s Richtwert moved from €6.67 to €6.74/m² this year, an increase of just 1%, and the next increase is capped before a new inflation-smoothing system starts later.

For someone buying a home to live in, none of this affects the ownership case. For someone buying purely for rental income, it can decide the deal.

Rental characteristic	Conventional regulated Altbau	Freely financed Neubau
Rent formation	Statutory framework plus permitted adjustments	Mostly market-based
Current Vienna Richtwert	€6.74/m² base	Not applicable
Ability to capture rising market rents	Limited	Much stronger
Legal complexity	High	Usually lower
Better fit today	selective/value-add investment	conventional buy-to-let

Can a Vienna Altbau still be a great rental investment?

Yes, a Vienna Altbau can still work extremely well as a rental investment when the legal status or purchase price breaks the usual regulated-rent equation.

The clearest example is a later-created apartment inside an old building. Certain attic apartments built under post-2001 permits fall into partial MRG application and can have much freer rent-setting than the original apartments downstairs.

Other units can qualify for an angemessener Hauptmietzins in specific circumstances. Large apartments and some special legal situations can also produce a different outcome. We would have a lawyer verify those exceptions rather than assume them from a sales brochure.

Price can solve the problem too. If a regulated apartment is bought cheaply enough, a lower permitted rent can still produce an acceptable yield.

There is also the refurbishment route. A badly configured apartment in a good building and strong micro-location may create most of its return through better layout, restoration and eventual resale.

The weak trade is paying an emotional owner-occupier price for a normal regulated Altbau and then modelling the rent as though the MRG did not exist.

Which gives a better rental yield in Vienna now: Neubau or Altbau?

Freely rentable modern apartments currently offer the cleaner route to a good Vienna rental yield, especially in well-connected outer districts.

EHL’s latest research puts average investment-apartment selling prices at roughly €7,000/m² after a 6% annual increase, while average net rents reached €16.20/m² after rising 8.6%. That faster rental growth has improved yields.

The better numbers often sit outside the expensive center. In districts such as Ottakring and Hernals, and increasingly Liesing, EHL reports purchase prices around €5,800/m² and rents near €14.50/m². That combination can support initial yields above 3.6%. Simmering has also started getting more investor attention because prices remain comparatively moderate while transport links are good.

Current listings show similar economics in actual projects. A Floridsdorf investment development marketed by EHL is quoting expected yields around 3.6% to 3.8%, while a Liesing project is quoting expected rents of roughly €13.50 to €14.50/m².

A conventional regulated Altbau can beat those yields, but usually only when the purchase price is low enough or its legal status is unusually favorable.

This is one of Vienna’s less intuitive features today: the cheaper apartment can easily produce the weaker rental return.

Segment	Indicative purchase level	Indicative rent	Yield signal	Our reading
Modern Vienna investment apartment, average	about €7,000/m²	€16.20/m² average	3%+ in many cases	simple income case
Modern outer districts	around €5,800/m²	around €14.50/m²	above 3.6% possible	often the best balance
Selected Floridsdorf projects	project-specific	project-specific	around 3.6–3.8% expected	current real-world example
Standard regulated Altbau	highly variable	legally constrained	deal-specific	price must compensate
Special-status Altbau	highly variable	potentially freer	potentially competitive	legal due diligence is essential

Will Vienna’s Neubau shortage keep pushing new-build prices up?

Vienna’s shrinking Neubau pipeline should support good new-build prices, but we would still avoid paying a scarcity premium for a generic apartment in a location full of substitutes.

Vienna completions have fallen sharply from the 2022 level, and current forecasts put the next couple of years around half that peak. National building permits have also been running at historically weak levels.

The rental side looks even tighter. OTTO expects commercially developed rental apartments to make up only around 3% of Vienna’s 2027 completions.

The effect on purchase prices will depend heavily on location. An infill Neubau in Josefstadt, Neubau or Währing competes with very little new supply. A two-bedroom apartment inside one of Vienna’s large development areas may still compete with dozens of similar units in the same district.

We would therefore pay for scarcity at the micro-location level rather than treating every newly built apartment as scarce.

Will Vienna’s gas phase-out and energy costs make Altbau much more expensive to own?

Vienna’s gas phase-out creates a real long-term cost for older buildings, but energy bills alone are nowhere near large enough to wipe out today’s Altbau price advantage.

The city wants heating and hot water in buildings to run entirely on renewable energy by 2040. Vienna says roughly 600,000 households still need their heating converted, alongside around 260,000 gas cooking appliances. Those sources currently account for close to 90% of CO₂ emissions from the city’s building sector.

Older apartment buildings are heavily exposed because individual gas boilers are still common. The City of Vienna says conversions often work better at whole-building level than apartment by apartment. Depending on the street and building, the eventual solution may involve district heating, a shared heat pump, geothermal energy or a local heating network.

Vienna’s Wärmeplan now maps the city into areas for existing district heating, future district heating, pioneer expansion zones and local renewable solutions. Before buying an Altbau today, we would check the building against that plan, ask whether the owners have discussed conversion and find out how much money is already sitting in the reserve.

The heating-cost arithmetic is much less frightening than the capital-expenditure risk. Using the 70 m² example above, first occupancy costs roughly €193,000 more than existing stock. Even a large €1,500 annual energy saving would take more than a century to recover that difference if we looked at energy bills alone.

The real danger is an inefficient apartment inside a building that soon needs new windows, insulation and a heating conversion. A renovated Altbau with good windows, an improved roof and façade, and a modern communal heating system can narrow the technical gap with Neubau substantially.

Heating issue	Typical Altbau	Typical recent Neubau	What we check
Individual gas heating	Still common	increasingly rare	conversion route
District heating/heat pump readiness	varies by building	often built in	local infrastructure
Thermal refurbishment need	can be substantial	usually much lower	façade, windows, roof
Building-wide coordination	often necessary	limited issue	owners’ meeting minutes
2040 compatibility	needs investigation	generally stronger	heating plan and technical documents

Does Vienna Altbau still sell more easily than Neubau?

A really good Vienna Altbau remains unusually liquid because buyers keep paying for characteristics that cannot be reproduced through new construction.

EHL’s latest Zinshaus research gives us a useful clue. Prices for entire historic rental buildings fell well below their previous peaks after financing costs rose, yet individual Altbau condominiums in good locations held up much better. EHL has seen cases where the square-metre value achieved through individual apartment sales sits up to roughly 30% above the value implied by selling the whole building.

That gap shows how differently owner-occupiers and professional investors value the same historic stock. Institutions focus heavily on regulated rent, financing and building economics. A private buyer may gladly pay more for high ceilings, original details, light and an established neighborhood.

The resale premium is selective. A bright third-floor apartment with a lift, quiet bedrooms and a sensible layout can attract a broad buyer pool. A dark courtyard unit, ground-floor apartment or fifth-floor walk-up can remain difficult even during a stronger market.

So we would never buy “Altbau” as a category. We would buy the specific features that future Vienna buyers are already proving they will pay for.

Does a Vienna Neubau make more sense if you may sell again in five years?

A Vienna Neubau can be easier to resell after five years, but paying too much upfront is a bigger danger than choosing the wrong building age.

Austrian property purchases still carry heavy friction. Real-estate transfer tax is generally 3.5% of the purchase price, land-register ownership registration normally costs 1.1%, legal or notary work can add roughly 1–3%, and buyer brokerage can reach 3% plus VAT on larger transactions. Financing can add further registration costs.

That means a buyer begins several percentage points behind before the apartment moves in value.

Neubau helps because five years later the building is still relatively modern and major repairs should be limited. But the higher initial price also raises the euro amount of several transaction costs.

Paying €600,000 for a generic new apartment and selling after five years can be less forgiving than buying an excellent €450,000 Altbau that already has deep owner-occupier demand.

For a short holding period, we would focus on an apartment that could sell easily today: strong transport, good light, normal layout, useful outdoor space if possible and no obvious building problems.

Where does Altbau make the most sense in Vienna today?

Vienna Altbau looks strongest in established neighborhoods where historic housing is part of what people actually want to buy and new construction is difficult to add.

That includes the obvious inner districts such as Neubau, Josefstadt and Alsergrund, but the opportunity is broader. Währing, parts of Margareten, Ottakring and Hernals can offer the same Gründerzeit character at lower entry prices.

Ottakring and Hernals are especially interesting now because EHL has recorded rising demand there since 2024 while investment purchase prices remain around €5,800/m² in the broader outer-district sample. New construction is also becoming thinner in many established western neighborhoods.

We want strong natural light, quiet sleeping rooms, a normal floor plan, a good floor level and either a lift or a price that properly reflects the lack of one. The building should have enough money in its reserve and no obvious stack of delayed repairs.

A €6,500/m² Altbau in an excellent street can be a much better buy than a €5,800/m² one beside heavy traffic or inside a neglected building.

Where does Neubau make the most sense in Vienna today?

Vienna Neubau currently looks best in well-connected outer districts where buyers get modern construction without paying central-city trophy prices.

EHL’s current numbers make the case quite clearly. Purchase prices around €5,800/m² and rents around €14.50/m² in parts of the outer city can push initial yields above 3.6%.

Ottakring, Hernals, Liesing and Simmering can therefore produce interesting modern investments when transport is good. Current projects in Floridsdorf are also being marketed with expected yields around 3.6% to 3.8%.

We are more careful with giant development zones. Donaustadt and Floridsdorf will benefit from Vienna’s broader fall in construction, but some projects still contain many near-identical units. A landlord selling or re-letting at the wrong moment may find several comparable apartments competing nearby.

The strongest Neubau for us is usually a compact one- or two-bedroom apartment with a balcony, efficient heating, low running costs and fast public transport in a district where people already want to live.

Neubau profile	Purchase-price pressure	Rental case	Competition risk	Our view
Prime central prestige project	Very high	high rent, weaker yield	low	mainly a lifestyle or capital-preservation buy
Inner-district infill	High	strong	low	attractive if premium stays reasonable
Established outer district	Moderate	strong	moderate	often the best risk/reward
Large development zone	Moderate to high	good tenant demand	higher	choose unit and micro-location carefully
Weakly connected peripheral project	lower	uncertain	can be high	cheap Neubau can still be a bad buy

What should you buy in Vienna today if you plan to live in the apartment yourself?

For a long-term owner-occupier in Vienna today, we would usually buy a good Altbau and keep the Neubau price difference in our pocket.

The reason is straightforward. Existing apartments average €4,645/m² while first occupancy averages €7,395/m². As seen above, that citywide gap is roughly 59%, large enough to cover a serious renovation budget in many cases.

An owner-occupier also avoids the main financial weakness of Altbau: rent regulation. If we live there ourselves, the Richtwert does not reduce our monthly income because there is no rental income to reduce.

That leaves us with the things Vienna buyers tend to value for years: good streets, ceiling height, large windows, room proportions and limited supply of genuinely attractive historic apartments.

We would switch to Neubau when the household genuinely needs features that are difficult to retrofit, such as barrier-free access, reliable lift access, a terrace, predictable maintenance or a building already prepared for the post-gas heating system.

A beautiful but badly maintained Altbau is still a bad purchase. Yet when the building is sound and the apartment is good, today’s pricing gives the owner-occupier more value in older stock.

What should you buy in Vienna today if you want rental income?

For a normal long-term rental investment in Vienna today, we would choose a freely rentable Neubau over a conventional regulated Altbau.

The strongest recent evidence comes from the rent side. EHL’s average net rent for modern investment apartments rose 8.6% to €16.20/m² while selling prices increased around 6%. Current yields can exceed 3.6% in several outer districts, and actual projects are being marketed around 3.6% to 3.8%.

Meanwhile, the commercial rental construction pipeline is collapsing. As pointed out above, OTTO expects those apartments to account for only around 3% of Vienna completions in 2027. That should keep pressure on the supply of modern, freely rentable homes.

A standard regulated Altbau cannot fully capture that rental squeeze. The acquisition price may be cheaper, but legal rent ceilings can absorb much of the apparent advantage.

We would still buy Altbau when the apartment has a favorable legal status, a large enough discount or clear refurbishment upside. A legally freer attic apartment inside a historic building can be especially attractive because it combines an established location with stronger rental economics.

But for someone who simply wants predictable rent, manageable building costs and an asset that benefits directly from Vienna’s current rental shortage, Neubau is the cleaner choice.

So is Neubau or Altbau the better buy in Vienna now?

Altbau is the better buy in Vienna now for most long-term owner-occupiers, while carefully selected Neubau wins for most conventional rental investors.

For people buying a home, we think the Altbau discount is currently too large to ignore. Existing apartments average about €4,645/m² against €7,395/m² for first occupancy. A good historic apartment can absorb meaningful refurbishment and still leave the buyer well below Neubau pricing.

The best Altbau purchase today is a bright apartment in an established neighborhood, inside a building that has already dealt with its biggest technical problems or has enough reserves to do so. Its architectural scarcity gives it a strong resale audience, while the owner-occupier never suffers from regulated rent.

For landlords, the market points the other way. Modern net rents are rising faster than investment-apartment prices, selected yields are back above 3.6%, vacancy is tight and future commercial rental construction is falling sharply. A freely rentable Neubau can capture those conditions directly.

We would avoid two purchases in particular: a generic Neubau carrying a huge premium over better-located resale stock, and a regulated Altbau bought at an emotional owner-occupier price by someone expecting market-rent returns.

Today’s Vienna market rewards a more specific choice. Buy Altbau when its price gives you enough room to absorb building risk. Buy Neubau when rent freedom, low near-term capital expenditure and modern usability genuinely earn back the premium.
