Get all the data you need about the real estate market in Buenos Aires
SUMMARY
Yes. In most cases, it is better to start with a good used apartment in Buenos Aires now because the price gap with new construction has become large enough to outweigh the advantages of being the first owner.
The market is splitting in two. Used-apartment prices are barely moving, while new housing is being pushed higher by replacement costs, especially labor and construction inputs.
The discount is not uniform. It becomes much more powerful as apartments get larger: the official gap is roughly 20% for small units but can exceed 50% for three-room apartments.
That changes the decision from “old finishes versus new finishes” into “how much usable apartment can the same budget buy?” At US$150,000, the difference can be another room or roughly 15 to 25 extra square meters in some established neighborhoods.
Actual transaction data make used apartments look more negotiable than listing portals suggest. The latest M² Real reading puts used CABA closing prices at US$2,112/m², while broad asking-price indices remain materially higher.
Renovation does not automatically erase the advantage. A dated but functioning apartment can absorb a kitchen, bathroom and cosmetic update and still remain well below the cost of a comparable new unit; a building with neglected infrastructure is a different story.
The biggest hidden risk is often outside the apartment. Façade work, elevators, roofs, vertical plumbing and weak consorcio finances can turn a cheap purchase into a series of extraordinary assessments.
New buildings are not automatically cheaper to own month to month either. Pools, gyms, permanent security, multiple elevators and large common areas can make expensas structurally higher even when major repair risk is lower in the first years.
For investors, the used-apartment advantage starts with the denominator: a lower acquisition price can create a better rental yield even if a new unit achieves somewhat higher rent. The rent premium has to be large enough to justify the purchase-price premium.
For owner-occupiers, the logic is even more practical. Good light, a sensible layout, a maintained building and more space usually matter for longer than untouched cabinets or a new lobby.
The best opportunity is not “buy old.” It is to buy an old interior inside a building that has already dealt with the expensive problems. At today’s spreads, new construction has to offer something genuinely useful — accessibility, parking, security, zero renovation or amenities the buyer will actually use — to justify the extra cost.
Why are old apartments in Buenos Aires suddenly more interesting to buy?
Old apartments in Buenos Aires look unusually attractive today because resale prices have barely moved while the cost of producing new housing keeps climbing.
Zonaprop's latest CABA index puts the average apartment asking price at about US$2,471/m². Prices have risen only 1.3% over the past 12 months, the weakest annual increase in 28 months, and they remain 11.7% below the historical peak.
The resale market looks even softer once we stop looking at advertisements and look at completed deals. The M² Real index produced by RE/MAX Argentina, Universidad del CEMA and Reporte Inmobiliario put the effective closing price of used apartments at US$2,112/m² in its latest release, down 0.9% from a year earlier.
New construction faces a very different cost curve. CAMARCO's latest indicator shows the cost of building a typical Buenos Aires apartment building rising another 17% so far this year. Labor costs are up 24.8%, while materials are up 13.2%.
That combination explains why old apartments deserve another look. New units are being priced against today's replacement costs, while owners selling existing apartments are still dealing with what buyers will actually pay.
How much cheaper is an old apartment than a new one in Buenos Aires today?
The discount on used apartments in Buenos Aires is now large enough to change what buyers can afford, especially once we move beyond studios.
The latest available Buenos Aires City statistics show used apartments averaging roughly US$2,561/m² for one-room units, US$2,343 for two-room units and US$2,160 for three-room apartments. Newly built units in the same dataset average around US$3,105, US$3,215 and US$3,349 respectively.
The gap therefore gets wider as apartments get larger. A new studio carries roughly a 21% premium. For a two-room apartment, it is about 37%. For a three-room apartment, it reaches roughly 55%.
That last number is hard to ignore. At the average three-room prices, US$150,000 buys close to 69 m² on the used market but only about 45 m² new.
| Apartment type | Used asking price | New asking price | New-build premium | Space for US$150k used | Space for US$150k new |
|---|---|---|---|---|---|
| 1 room | US$2,561/m² | US$3,105/m² | 21% | 59 m² | 48 m² |
| 2 rooms | US$2,343/m² | US$3,215/m² | 37% | 64 m² | 47 m² |
| 3 rooms | US$2,160/m² | US$3,349/m² | 55% | 69 m² | 45 m² |

Are old Buenos Aires apartments really selling at those prices?
Used apartments in Buenos Aires are currently closing below the prices buyers usually see on property portals, so there is still room to negotiate.
The useful number here comes from the M² Real index, which tracks completed transactions rather than listings. Its latest reading for used apartments was US$2,112/m².
That is especially interesting next to Zonaprop's overall CABA asking price of US$2,471/m². The two datasets are not perfectly comparable because Zonaprop includes a different mix of properties, but they still point in the same direction: advertised prices are not transaction prices.
There is another piece of evidence. Zonaprop reported earlier this year that about one-quarter of listings had been repriced downward over the previous six months, with an average reduction around 6%.
So buyers should be careful with statements such as "this apartment is already cheap at US$2,300/m²." The seller may still close lower, particularly when the property has been listed for a while or needs work.
The market itself is not frozen. The Colegio de Escribanos recorded 6,051 CABA property transactions in its latest monthly report, the strongest month of the year. Buyers are transacting; they simply have enough alternatives that sellers cannot push used prices aggressively higher.
Is the old-versus-new price gap unusually large right now?
Yes. Today's discount on used apartments is too wide to dismiss as normal depreciation for an older property.
A brand-new apartment should obviously cost more. Buyers get new installations, contemporary finishes, fewer immediate repairs and, in many projects, modern amenities.
The real question is how much more those advantages are worth.
Current official data show premiums that can run from roughly 20% for small apartments to more than 50% for larger ones. Meanwhile, effective used-apartment prices are slightly below where they stood a year ago, and CAMARCO says construction costs have climbed 17% so far this year.
Those two markets are moving differently. Existing apartments are constrained mainly by household purchasing power and negotiation between individual buyers and sellers. Developers still have to cover land, construction, labor, financing, taxes and a margin.
As construction costs rise, the premium on new apartments can widen without the apartment itself becoming proportionally better. That is what looks unusual now.
Don't buy the wrong property, in the wrong area of Buenos Aires
Buying real estate is a significant investment. Don't rely solely on your intuition. Gather the right information to make the best decision.
Does renovation wipe out the savings from buying an old apartment in Buenos Aires?
A normal renovation usually leaves plenty of the old-apartment discount intact; a complete rebuild can eat almost all of it.
Reporte Inmobiliario recently calculated nearly US$13,000 to fully renovate a small kitchen and bathroom in Buenos Aires. Its model includes demolition, new plumbing and drainage, gas work, electrical wiring, finishes, fixtures and kitchen furniture.
Imagine a 60 m² used apartment priced US$700/m² below a comparable new unit. The initial difference is US$42,000. Spending US$13,000 on a proper kitchen and bathroom still leaves US$29,000. Add painting, floor restoration and several smaller upgrades and there can still be a meaningful saving.
The calculation changes fast once the apartment needs everything: electrical installation, plumbing, windows, heating or air-conditioning, several wet rooms and major layout changes.
These days, the sweet spot is often an apartment that looks old but works properly. Beige tiles and dated kitchen cabinets can be fixed. Forty years of neglected infrastructure is much harder to price.
| Example on a 60 m² apartment | Approximate renovation cost | Remaining from a US$42k purchase gap |
|---|---|---|
| Light cosmetic update | US$8k | US$34k |
| Kitchen + bathroom benchmark | US$13k | US$29k |
| Significant renovation | US$25k | US$17k |
| Deep renovation | US$40k | US$2k |
| Near-total rebuild | US$50k+ | Discount effectively gone |
Which Buenos Aires neighborhoods give old-apartment buyers the biggest advantage?
The old-apartment discount is particularly powerful in established neighborhoods where new construction has become expensive, including Palermo, Belgrano, Núñez and Caballito.
Recent Buenos Aires City data show large differences between new and used units inside the same parts of the city. Earlier official figures, for example, put used apartments around US$2,879/m² in Palermo versus US$4,220 new. Belgrano was around US$2,768 versus US$4,045, while Núñez was roughly US$2,847 versus US$4,065.
Caballito stands out because the absolute price remains lower while the new-build premium is still substantial: roughly US$2,167/m² used versus US$3,231 new in that comparison.
With US$150,000, the difference can mean roughly 15 to 25 extra square meters depending on the neighborhood.
That is often more important than whether the lobby looks newer. In Palermo or Caballito, those extra square meters can turn a compact one-bedroom into a comfortable two-bedroom or make room for a proper home office.
| Neighborhood | Used US$/m² | New US$/m² | Approx. new premium | US$150k buys used | US$150k buys new |
|---|---|---|---|---|---|
| Palermo | 2,879 | 4,220 | 47% | 52 m² | 36 m² |
| Belgrano | 2,768 | 4,045 | 46% | 54 m² | 37 m² |
| Núñez | 2,847 | 4,065 | 43% | 53 m² | 37 m² |
| Caballito | 2,167 | 3,231 | 49% | 69 m² | 46 m² |
| Recoleta | 2,590 | 3,481 | 34% | 58 m² | 43 m² |

Are older Buenos Aires apartments expensive to maintain?
An old Buenos Aires apartment can be cheaper to run every month than a new tower, although the risk of occasional large repairs is higher.
Monthly expensas depend heavily on what the building provides. Pools, permanent security, gyms, multiple elevators, coworking areas and large common spaces all need staff, maintenance and utilities.
Recent analysis of thousands of Buenos Aires rental listings found a median around AR$170,000 in expensas for two-room apartments. Listings with gyms were around AR$292,000, pools around AR$250,000, SUMs around AR$248,500 and 24-hour security around AR$220,000.
Those figures do not mean a gym alone adds AR$122,000. Buildings with one amenity often have several. But they show why a simple 1970s building can sometimes have much lower monthly charges than a modern tower.
The trade-off comes later. A modest old building may eventually need façade work, an elevator overhaul or new pipes. A new building can charge more every month but offer fewer large repairs during the first years.
So we would look at both numbers: ordinary expensas today and the building's likely capital expenditure over the next several years.
Can an old Buenos Aires building suddenly become very expensive?
Yes. The biggest financial risk when buying an old apartment in Buenos Aires often sits in the building, not inside the unit.
A seller can renovate the kitchen and polish the parquet before showing the apartment. That tells us almost nothing about the façade, roof, elevators, water tanks, main electrical system or vertical plumbing shared by the building.
Buenos Aires requires periodic façade conservation inspections, with inspections becoming more frequent as buildings age. Buildings over 55 years old face five-year intervals, and those above 70 years are inspected every four years.
We would therefore want to see what the consorcio has actually been doing.
Recent meeting minutes can reveal planned extraordinary assessments. Building accounts can show whether there is money in reserve. Previous work on façades, elevators, gas systems, roofs and pipes tells us whether the building has been maintained gradually or has simply postponed expensive work.
This is where a US$15,000 bargain can disappear very quickly. If the owner is selling just before a major building project, part of the discount already belongs to somebody else.
Buying real estate in Buenos Aires can be risky
An increasing number of foreign investors are showing interest. However, 90% of them will make mistakes. Avoid the pitfalls with our comprehensive guide.
Is paying 30% to 50% more for a new apartment ever worth it?
A new apartment in Buenos Aires can absolutely be worth the premium, but right now it needs to solve a real problem for the buyer.
There are buyers for whom the difference makes sense. Someone who wants to move in immediately, avoid contractors, have modern accessibility, parking, permanent security and a pool may get real value from a newer development.
The mistake is automatically translating "new" into "better investment."
Part of today's new-build price reflects expensive construction. CAMARCO's latest numbers show building costs up 17% so far this year, with labor up almost 25%. Buyers are indirectly absorbing that higher cost base.
And the premium does not end at closing. Amenity-heavy buildings often come with higher monthly expensas.
For a buyer who regularly uses the gym, pool, security and coworking space, that can still be a good trade. Someone who mainly wants location, light, space and a good floor plan may be paying tens of thousands of dollars for features that barely change daily life.
We would happily pay more for a genuinely better apartment. Paying more just because nobody has lived there yet is much harder to defend at current spreads.
Does mortgage financing favor new apartments over old ones now?
Mortgage financing is not giving new apartments a decisive advantage because most Buenos Aires purchases are still happening without a mortgage.
The latest Colegio de Escribanos figures recorded 959 mortgage-backed deeds out of 6,051 CABA purchases. That is about 15.8% of transactions.
Across the first seven months of the year, there were 5,111 mortgage-backed transactions among 35,528 purchases, or roughly 14.4%.
More tellingly, mortgage transactions fell 31.2% year over year in the latest month and were down roughly 36% over the first seven months. Total property transactions over the same seven-month period fell only 1.8%.
So Buenos Aires currently has a surprisingly active property market without mortgages driving most of the volume.
A qualifying used apartment can still be financed. The important issues are the property's documentation, title and whether the bank accepts it as collateral.
Properties still under construction are different because conventional mortgages generally become easier once the unit can be legally mortgaged. Developers often bridge that gap with their own installment structures.
For most buyers today, financing does not give us a strong reason to choose new over used.
| Current CABA transaction data | Total |
|---|---|
| Latest monthly property deeds | 6,051 |
| Mortgage-backed deeds | 959 |
| Mortgage share | 15.8% |
| First seven months: total deeds | 35,528 |
| First seven months: mortgage deeds | 5,111 |
| Mortgage share for the period | 14.4% |

Is an old apartment better for rental investment in Buenos Aires?
For a normal long-term rental investment, a well-bought used apartment currently has a better starting equation than an expensive new unit.
Zonaprop's latest CABA index puts average gross rental yield around 5.76%, meaning roughly 17.3 years of gross rent would recover the purchase price before expenses, vacancy and taxes.
The old-versus-new comparison comes down to the denominator: how much capital we have to put in.
Suppose two apartments can realistically rent for similar amounts but one costs 30% less because it is older. The used apartment immediately produces a much higher percentage yield.
Even if the new apartment rents for more, that rental premium has to be large enough to compensate for its purchase-price premium.
Imagine a new apartment costing US$150,000 and renting for US$750 a month. Gross yield is 6%. If a comparable used apartment costs US$115,000, it only needs to rent for US$575 a month to produce the same 6%.
A modern apartment in Palermo or Núñez can certainly command higher rent, particularly when it has parking, security or amenities. But we would want to see that premium in actual comparable rentals before paying for it.
For ordinary residential investing, the cheaper entry price currently gives used apartments a real head start.
Is the Buenos Aires used-apartment market weak enough to negotiate hard?
Yes. Buyers of used apartments still have negotiating power today even though Buenos Aires property sales are running at healthy levels.
The latest Colegio de Escribanos report counted 6,051 transactions in one month. That was the strongest month of the year and one of the best comparable monthly readings in many years.
Yet the first seven months still finished 1.8% below the same period a year earlier.
Prices tell a similar story. Zonaprop's asking-price index is only 1.3% higher year over year, while the M² Real index shows used apartments closing 0.9% below last year's level.
It is a liquid market, but not a booming one.
That is a good environment for buyers. There are enough transactions to know the market is functioning, but sellers cannot assume that another buyer will arrive next week at any price.
As seen above, earlier Zonaprop data also showed roughly one in four listings being repriced downward, with reductions around 6% on average.
A good used apartment will still attract competition. A mediocre one that has sat online for months should be treated very differently.

Which old apartments in Buenos Aires are actually bad deals?
The worst old apartments in Buenos Aires are cheap for reasons that renovation cannot easily fix.
A dated bathroom does not worry us much. Neither do old cabinets, ugly paint or worn floors if the underlying materials are good.
Poor natural light is much harder to solve. So are a bad orientation, a noisy position, an awkward floor plan, no elevator on an inconvenient floor or an apartment facing a dark internal air shaft.
Then there is the building itself. Old plumbing, pending façade work, repeated elevator problems and weak consorcio finances can turn a visually attractive purchase into years of special assessments.
The purchase price therefore needs one simple adjustment before we compare anything:
purchase price + immediate renovation + transaction costs + foreseeable building work.
If a US$105,000 apartment needs US$20,000 inside and we can already see another US$10,000 of likely extraordinary building expenses, we should think of it as roughly a US$135,000 decision.
At that point, a cleaner US$140,000 alternative may be the better deal.
The best bargains these days are often boring: good street, good light, sensible layout, maintained building, dated interior.
Should someone living in the apartment choose old or new in Buenos Aires?
For someone buying a home to live in, we would currently start with used apartments because the extra space is often worth much more than the newer finishes.
The numbers are especially compelling for families.
Using the official three-room averages above, US$150,000 buys around 69 m² used versus roughly 45 m² new. That is a difference of about 24 m².
Twenty-four square meters can change how long an apartment remains useful. It can mean another bedroom, a separate office, a proper dining area or simply enough storage that a family does not need to move again three years later.
The longer someone expects to stay, the easier it is to justify renovating. A US$15,000 renovation spread over ten years is very different from spending the same amount before reselling after two.
New makes more sense when convenience dominates the decision. Someone who hates construction work, needs step-free access, wants parking or values building security highly may rationally pay the premium.
But for buyers primarily interested in neighborhood, light and usable space, old apartments currently give much more freedom within the same budget.

So, is it better to buy an old apartment in Buenos Aires now?
Yes, in most cases we would look at a good used apartment before paying the current premium for a new one.
The gap has become hard to ignore. Recent official data show new apartments costing roughly 20% more at the small end of the market and more than 50% more for some larger units. At the same time, the latest transaction-price index has used apartments closing slightly below last year's level.
New construction is facing the opposite pressure. CAMARCO says building costs are already up 17% this year, including almost 25% for labor. Developers cannot simply ignore those costs.
Renovation is expensive too, so buying the cheapest wreck is usually the wrong interpretation of this opportunity. Reporte Inmobiliario's roughly US$13,000 kitchen-and-bathroom benchmark shows how quickly serious work adds up.
The strongest purchase today is more specific: an older apartment with good light, a strong layout and a building that has already dealt with the expensive maintenance, but whose interior is dated enough to keep the price down.
For investors, the lower acquisition cost can lift rental yield. For owner-occupiers, it can buy an extra room or another 15 to 25 square meters in the same neighborhood. For both, that is more valuable than being the first person to use the kitchen.
New apartments still win when modern accessibility, zero renovation, parking, security or specific amenities genuinely matter to the buyer.
But as of now, new construction carries the burden of proof. With the price gap this wide, we would need a clear reason to pay the premium.
The best old apartments in Buenos Aires are currently better buys than comparable new ones. The key is choosing an old interior, not an old problem.
OUR METHODOLOGY
This analysis tests whether it is better to buy an old apartment in Buenos Aires now by treating the question as an evidence-aggregation problem rather than a matter of real-estate intuition. We compare old and new apartments across the dimensions that materially change the decision: price per square meter, usable space, renovation costs, building condition, recurring expenses, financing, rental economics and location.
For each dimension, we prioritized the freshest available figures from official Buenos Aires statistics, completed transactions, market indices and primary industry data. Where datasets measure different things — especially asking prices versus actual closing prices — we use each for what it shows best rather than treating them as interchangeable.
The citywide asking-price series is used to understand the broader level and direction of advertised values. The M² Real index is used separately because it tracks effective closing prices for used apartments and gives a cleaner view of what buyers are actually paying. The latest observation used here is July 2026, at US$2,112/m², 0.9% below July 2025.
Official IDECBA data are the main basis for the old-versus-new price comparisons by apartment size and neighborhood. Those figures let us test not only the percentage premium on new construction, but also what the same fixed budget buys in square meters.
Construction-cost pressure is checked against CAMARCO's July 2026 indicator. We use it as a replacement-cost input, not as a direct forecast of apartment prices. It helps explain why new construction can keep getting more expensive even while the resale market remains relatively soft.
Renovation examples and fixed-budget comparisons are scenario tests, not market forecasts. They are included to see whether the apparent discount on an older apartment survives once realistic additional costs are added.
We also look for convergence rather than relying on one headline number. The case for used apartments becomes stronger when the price-per-square-meter gap, transaction prices, construction costs, renovation economics, expensas, mortgage activity and rental yields all point in a similar direction.
The conclusion does not assume that old is automatically better than new, or that the cheapest apartment is the best deal. We are looking for the conditions under which the current market gives one option a clear advantage, and for the risks that can erase that advantage.
Key sources used for this analysis include: Zonaprop's CABA sale-price index, IDECBA's official apartment-sales database, IDECBA's used-apartment price series by neighborhood, IDECBA's new-apartment price series by neighborhood, UCEMA's July 2026 M² Real release, Reporte Inmobiliario on July 2026 effective closing prices, CAMARCO's July 2026 construction-cost indicator, the Colegio de Escribanos de la Ciudad de Buenos Aires on July 2026 property deeds and mortgages, Buenos Aires City guidance on façade conservation inspections, and Zonaprop's CABA rental-yield index.
