What to Ask When Buying a Used Property in Uruguay 2026

INGAR · 2026-02-13 · Purchase

Summary

Buying a used property in Uruguay can be an excellent deal, but also a headache if you don't know where to look. In our experience, the most costly surprises don't show up during the Saturday 11 AM visit: they appear later, when you discover the pipes are galvanized iron, the "fixed" moisture was just a coat of paint, or the building has approved an extraordinary expense of USD 800 per unit to replace the elevator.

This article is not a generic checklist. It's what we verify when advising a buyer, with real costs we see in Montevideo in 2026 and the red flags that only appear when you've spent years touring properties.

Complement this guide with what a notary does in a sale, build your budget with what costs are involved in buying a property, and learn how to compare prices with how to assess if a price is fair.

Before the visit: research the building

The building matters as much as the apartment. We see buyers who fall in love with a renovated unit with porcelain tile and new fixtures, not realizing the building still has the original 1965 drainage pipes and the rooftop leaks. Your apartment may be immaculate, but if the plumbing column breaks or the facade needs repair, you'll pay your share regardless.

What to find out before stepping inside

Year of construction: Montevideo buildings from the 1950s-60s (many in Pocitos, Centro, and Cordón) typically have cast iron and galvanized iron pipes. Those pipes have a lifespan of 40-50 years — meaning they've already exceeded it. When they corrode internally, they reduce water pressure and contaminate with rust.
Building management: Look for reviews from neighbors. A building with good management and regular assemblies is a healthy sign. One where no one has met in years and the manager "handles everything" is a red flag.
Google Maps and Street View: Look at the facade from the street before going. If you see peeling paint, visible moisture stains, or cracks, you already know there are pending repairs.

The visit: what to look at and what to ask

There's a trick we always repeat: visit on a weekday at 6 PM, not on a Saturday morning. Saturday morning is the quietest moment of the week. On a Wednesday at 6 PM you hear the real noise: neighbors arriving, TVs, dogs, rush-hour traffic. If the property faces a main avenue, that visit will tell you more than ten photos.

Moisture: problem number one

Moisture is the most common problem we see in used properties in Montevideo, and the most disguised. Uruguay has a humid climate (annual average of 70-75% relative humidity), and that punishes any building with poor insulation.

Types of moisture and what to look for:

Rooftop seepage: Stains on the ceiling of the top floor, especially in corners. Ask when the last waterproof membrane was applied. A rooftop membrane lasts 10-15 years if properly installed; after 15, start budgeting.
Capillary moisture: Stains at the base of walls, typical on ground floor and first floor. Water rises from the foundation through porous walls. It's the most difficult and expensive to resolve.
Condensation: Appears on cold, poorly ventilated walls, typical in south-facing bedrooms and bathrooms without extractor fans. Black mold in ceiling corners is the telltale sign.
Party wall seepage: Stains on lateral walls. Sometimes the problem is not yours but comes from the neighboring building, which complicates the solution.

The classic red flag: a single freshly painted wall in an apartment that wasn't otherwise renovated. If you see a wall with fresh paint and all the others look old, someone covered up moisture. Ask to see behind the furniture too — moisture hides where you don't look.

Real moisture repair costs

Problem	Solution	Estimated cost (2026)
Rooftop membrane (100 m²)	Asphalt or liquid membrane	USD 2,000 – 4,000 (depends on system)
Localized wall seepage	Localized repair + waterproofing	USD 300 – 800
Capillary moisture (entire ground floor)	Resin injection or chemical barrier	USD 2,000 – 5,000
Mold treatment + anti-moisture paint	Fungicide + special paint	USD 200 – 500 per room

Electrical installation: what you can't see can be dangerous

In buildings built before the 1980s, it's common to find fabric-insulated cables (yes, they still exist), fuse boards with ceramic fuses instead of thermal-magnetic breakers, and no residual current device. This isn't just an inconvenience — it's a real fire and electrocution risk.

What to check:

Electrical panel: Open the cover (ask permission first). If you see ceramic plug-type fuses, the installation is old. It should have individual thermal-magnetic breakers per circuit and a 30 mA residual current device.
Number of circuits: A 2-bedroom apartment should have at least 3-4 separate circuits (lighting, outlets, kitchen/oven, air conditioning). If everything runs on one circuit, rewiring is needed.
Ground wire: Verify that outlets have the third grounding pin connected. In many older buildings, the ground wire either doesn't exist or isn't connected.
UTE certificate: If electrical work was done, a Certificate of Conformity issued by UTE should exist. Ask for it.

Cost to rewire a 2-bedroom apartment: between USD 1,500 and 3,500, depending on whether walls need to be opened or cabling can be channeled. It's an expense many buyers don't budget for and then have to face for safety reasons.

Plumbing: galvanized iron, the silent enemy

If the building is from the 1950s to 1970s and the water pipes were never replaced, they are almost certainly galvanized iron. That material has a lifespan of 40-50 years. Today those pipes are 55-75 years old. What happens is they corrode internally: you lose pressure, the water comes out with a reddish tint, and eventually they crack.

How to detect it without being a plumber:

Open the hot and cold water taps simultaneously in the bathroom. If pressure drops noticeably, there's internal obstruction in the pipes.
Let the water run for a few seconds. If it comes out with a yellowish or reddish tint, it's rust from the pipes.
Ask directly: "Are the pipes the originals or were they replaced?" If no one knows, assume they're original.

Replacing pipes in a 2-bedroom apartment (hot + cold water, to PPR thermofusion): USD 3,000 – 6,000. If the drainage pipes also need replacing (cast iron to PVC), add USD 2,000 – 4,000 more, and that requires coordination with the building since the columns are common property.

Orientation: the sun matters more than you think

Montevideo is at latitude 34° south. That means the sun comes from the north, not the south. A north-facing apartment receives sun all year: in winter the sun enters low and deep (when you need it most), and in summer it enters higher and less directly.

Quick orientation guide for Montevideo:

North / Northwest: The best orientation. Sun all year, warm in winter, manageable in summer with curtains or an awning.
East: Morning sun, cool in the afternoon. Good option for bedrooms.
West: Strong afternoon sun, can be stifling in summer. You'll need good shutters or blackout curtains.
South: Little direct sun in winter. More light in summer (high sun). Suitable if you prioritize coolness, but in winter you'll feel the difference in heating and comfort.

A tip we always give: a rear unit facing north can be better than a front unit facing south. Don't just go by "front or rear"; what matters is which direction the main living room window faces.

Noise: don't trust the Saturday visit

Visit on a weekday at 6:00 PM. Neighbors are home, traffic is heavy, dogs are barking.
Ask if there are commercial spaces on the ground floor (bars, restaurants, gyms). A bar with music on Friday nights at 2 AM will change your quality of life.
Tap gently on shared walls. If they sound hollow, acoustic insulation will be poor.
Pay attention to the elevator: if the motor is near your floor (top or first), the noise can be a nighttime problem.

The building: questions most people never ask

This is where we see the most costly mistakes. The apartment can be perfect, but if the building needs major work, the bill comes to all co-owners proportionally according to their thousandths.

Common expenses: ask for the movie, not the snapshot

Never accept just "the common expenses are $X." Ask for the last 6 expense statements (at minimum 3). This shows you:

The trend: If expenses went from $12,000 to $18,000 in six months, something changed (doorman salary increase, OSE rate hike, new work).
Extraordinary expenses: They appear as separate line items on the statement. If you see "extraordinary: membrane," "extraordinary: elevator," you already know there are ongoing works.
Delinquency rate: Some statements detail the building's delinquency percentage. If it's above 15-20%, the building has a problem: those who pay end up subsidizing those who don't, and maintenance eventually deteriorates.

Reserve fund

The horizontal property law (Law 10.751) does not actually require a reserve fund: it only obliges owners to contribute to the expenses of administering, maintaining and repairing common areas. If the building has a reserve fund, it stems from its co-ownership regulations or an assembly decision. Ask whether one exists and how much is accumulated. A 20-unit building with a reserve fund of $50,000 has nothing. One with USD 15,000-20,000 is minimally prepared for an unexpected expense.

Approved or pending works

This is the key question: "Are there extraordinary expenses already approved at an assembly meeting that haven't been charged yet, or are there major works under discussion?"

This matters because if the assembly has already approved (for example) replacing the elevator, that expense will be distributed even if you didn't vote for it. You inherit it with the purchase. Ask for access to the minutes of the last 2-3 assemblies to verify.

Common works costs that affect your wallet

Work	Estimated total cost	Your share (20-unit building)
Full rooftop membrane	USD 5,000 – 12,000	USD 250 – 600
Elevator replacement	USD 30,000 – 55,000	USD 1,500 – 2,750
Facade painting and repair	USD 8,000 – 25,000	USD 400 – 1,250
Drainage column replacement	USD 4,000 – 10,000	USD 200 – 500
Water tank repair	USD 2,000 – 6,000	USD 100 – 300

These amounts are prorated by thousandths, not necessarily equal shares. A penthouse pays more than a studio. But in any case, a new elevator with a USD 2,000 charge per unit is a surprise nobody wants to receive a month after buying.

Building management

Who manages it? Under Law 16.575 (1994), managers of horizontal property buildings must be registered with the Registry of Building Administrators at the Ministry of Labor. Verify that it is a registered professional administrator.
Is there a supervisory committee? If no neighbors are checking the accounts, management has a free hand.
Are annual meetings held? If the last assembly was 3 years ago, the building has a governance problem.

The co-ownership regulations

Don't read it after buying. Read it before. Some things we've seen cause problems:

Prohibition on short-term rentals: If you plan to do Airbnb, verify that the regulations allow it. Many buildings expressly prohibit it.
Pet restrictions: Some older regulations prohibit pets or impose size limits.
Renovation limitations: Some regulations require unanimous approval for any facade modification, even enclosing a balcony.
Use of common areas: Who can use the rooftop, whether there's a grill area and how it's booked, parking rules.

Documentation: what your notary will ask for (and what you can check in advance)

The title study is the notary's job, but there are things you can ask the seller or real estate agent before spending money on that:

Questions that quickly filter out problems

"Who is the owner and how many owners are there?" If there are several (inheritance, divorce), the transaction becomes more complicated and takes longer. It's not an obstacle, but you need to know.
"Is there a current mortgage?" If there is, it's canceled with the proceeds from the sale, but the notary must process the cancellation. This adds time and paperwork.
"Is it up to date on property taxes and municipal fees?" Tax debts are tied to the land registry number, not to the person. If you buy with outstanding property tax, the problem becomes yours.
"Were any renovations done? Are they properly registered?" Any significant construction must be registered with BPS (work registry) and the city hall (building permit). If a balcony was enclosed without a permit, there may be an irregularity that later prevents you from selling or complicates your deed.

The BPS special certificate

When the deed is signed, the notary requests a special BPS certificate confirming the seller has no outstanding debts with the agency. It's valid for 180 days. If the seller did renovation work and didn't register it with BPS, there may be a problem at the time of signing. Ask directly: "Did you do any work and is it properly registered with BPS?"

Verification of renovations

If the apartment was renovated, ask:

Who did the work? Is there a responsible contractor?
Was the work registered with BPS? (mandatory for work with employees)
Was a construction permit obtained from the city hall?
Is there a warranty on the work?

A renovation done "off the books" without BPS registration can cause a problem at the time of signing if the notary detects that the improvements don't match the registered records.

Red flags: if you see these, stop and think

These are the signs that in our experience indicate you need to dig deeper before proceeding:

A freshly painted wall among old ones: Someone covered up moisture. Ask them to explain what was done and why.
Smell of moisture when entering: Especially on the ground floor or top floor. If they ventilated the place right before your visit and there's strong incense or air freshener, be suspicious.
Electrical panel with ceramic fuses: The installation is over 40 years old. Budget USD 1,500-3,500 for rewiring.
Discolored water or low pressure: Corroded pipes. Budget USD 3,000-6,000 for replacement.
Common expenses that are "unusually low this month": Ask for previous statements. If they won't give them to you, there's something they don't want you to see.
No assembly meeting in years: The building is run without oversight. There may be mismanaged expenses or deferred maintenance.
Vague answers about paperwork: "The notary will handle that later" can mean there's a problem they'd rather not mention until you're emotionally committed to the purchase.
Renovations without permits to show: Off-the-books work that may complicate your deed or generate a regularization cost for you.
Lots of cosmetic work, little real maintenance: New porcelain tile over walls with water issues, Italian fixtures with galvanized iron pipes underneath. Cosmetic fixes don't solve structural problems.

What you'll need to budget for (and almost no one tells you)

When you run the numbers on buying a used property, everyone talks about the price, the transfer tax (ITP), the notary fees. But there's a second budget you need to build: the cost of bringing the property to a truly habitable condition.

Item	Estimated range (USD)	When necessary
Full electrical rewiring (2 bed.)	1,500 – 3,500	Pre-1980 buildings without updates
Water pipe replacement (2 bed.)	3,000 – 6,000	Original galvanized iron pipes
Localized moisture repair	300 – 1,500	Localized seepage in wall or ceiling
Full moisture treatment	2,000 – 5,000	Structural problem (capillary, rooftop)
Window replacement (4-5 windows)	2,500 – 5,000	Iron frames without double glazing
Full paint job (2-bed. apt.)	800 – 1,500	Always, in practice

In a 1960s-70s building without updates, between plumbing, electrical, and windows you could be looking at USD 8,000-15,000 on top of the purchase price. That doesn't invalidate the transaction, but it needs to be factored into the price negotiation.

One final tip

In our experience, the best investment before buying a used property is not the notary (which is mandatory), but an informal technical inspection. Ask an architect or engineer you trust to come with you to the second visit. For a cost of USD 100-200, they can point out things you can't see: structural problems, hidden moisture, out-of-code installations. That gives you negotiating power or, in the worst case, saves you from a bad purchase.

Buying used is an excellent option in Uruguay: prices are more accessible, locations tend to be better (established neighborhoods, close to services), and with the right investment you can have a property worth much more than you paid. But you need to know where to look.
