How to Read a Building Before You Buy an Apartment
Most buyers focus on: the apartment the view the square meters the price Experienced buyers look first at: The building. Because you are not buying 80 or 100 sqm. You are buying a percentage of a living organism. And that organism can either protect — or slowly erode — your investment.
BUYING PROPERTY IN GREECE

1️⃣ The Ground Floor Tells the Truth
When you enter the building, observe:
Is it clean?
Is it properly lit?
Are there visible damages?
Is there a smell of humidity?
The entrance is the mirror of management quality.
If it feels neglected,
do not expect the rest of the building to function well.
As discussed in
“The Importance of First Impression: What the Ground Floor Reveals”,
first signals are rarely accidental.
2️⃣ The Common Expenses Ledger Speaks
Ask to review:
Outstanding debts
Historical balances
Extraordinary contributions
If you notice:
systematic delays
significant unpaid fees
long-standing conflicts between owners
then the building has a culture problem.
And culture does not change easily.
3️⃣ The Composition of Residents
Discreetly find out:
How many units are owner-occupied?
How many are rented?
Are there short-term rentals?
A building that is 80% rental
has a different long-term dynamic
than one with 80% owner occupancy.
Stability affects:
maintenance decisions
capital improvements
long-term value preservation
4️⃣ Infrastructure Never Lies
Check:
Elevator condition and age
Electrical panels
Basement (moisture, leaks)
Roof insulation
If a 30–40-year-old building has not undergone major maintenance,
the bill will eventually arrive.
And usually sooner than expected.
5️⃣ The Energy Behavior of the Building
It is not enough for the apartment to be renovated.
If:
the building has thermal losses
the windows are outdated
there is no external insulation
the living experience — and operating cost — suffer.
As analyzed in
“New Build vs Old Property: What You Really Pay Over Time”,
the structure of the building determines long-term cost efficiency.
6️⃣ The “Mentality” Factor
This cannot be measured on paper.
But it shows:
On notice boards
In small damages left unrepaired
In common area cleanliness
In how residents interact
A building functions at the level of its weakest link.
If chronic neglect exists,
value erosion is slow — but persistent.
7️⃣ Year of Construction Matters
Buildings from:
1960–1980 → different seismic standards
1980–2000 → transitional construction era
Post-2010 → modern specifications
This is not only about age.
It is about:
seismic codes
concrete quality
mechanical and electrical standards
The Big Mistake
Falling in love with the apartment
and ignoring the building.
Over a 10–20 year horizon,
the building impacts value more than the interior layout.
Conclusion
Before buying, ask:
Does the building function properly?
Is there financial discipline?
Is there a culture of maintenance?
Would I feel comfortable here for 15 years?
Because you are not buying square meters.
You are buying infrastructure, community, and behavior.
