The five costliest mistakes when buying a holiday home aren't emotional but technical: skipping the structural survey, misreading a damp patch, ignoring the state of the installations, forgetting the communal areas and underestimating the upkeep of a house that sits empty for months. That's the summary from Madrid's professional body of surveyors and technical architects — and on the coast, where salt air and humidity work overtime, every one of them costs more.
Mistake 1: buying without a structural survey
A 30-minute viewing with the seller standing next to you spots nothing. The defects that wreck a budget — structure, roof, waterproofing — are rarely visible to the naked eye. A qualified surveyor checks those points and, crucially, puts a number on what fixing them would cost. That number is the best negotiating tool you'll have, and it costs a fraction of what discovering it after signing does.
Mistake 2: shrugging off a damp patch
Condensation and water ingress are not the same thing. The first is fixed with ventilation and insulation; the second can mean redoing the waterproofing of a roof or terrace, and that changes the budget by an order of magnitude. On the seafront, salt air accelerates corrosion in reinforcement bars and window frames, so a discreet stain on a ceiling or at the base of a wall always deserves a second technical opinion before the deposit, not after.
Mistake 3: not checking the installations
Obsolete wiring, old lead piping, air conditioning that can't cope with an Andalusian summer: these are costs that show up in the first month and almost never appear in the listing. Checking them beforehand lets you do two things: negotiate the price with evidence, and budget the refurbishment realistically instead of by gut feel.
Mistake 4: looking only at the flat, not at the building
This is the classic mistake of the foreign buyer on the coast. You buy an immaculate apartment inside a community with a crumbling façade, an unlicensed pool or a failed building inspection (ITE/IEE), and any pending levies become yours from the day you sign. Before committing, ask for the community's minutes from recent years, the certificate confirming the seller is up to date with fees, and any technical report on the building.
Mistake 5: underestimating what an empty house costs
A holiday home spends most of the year shut up, and a shut-up house deteriorates: trapped damp, dried-out seals, pests, rust on railings and window frames. On the coast you must add anti-corrosion treatments and regular checks of terraces and roofs. It isn't an optional expense: it's what preserves the property's value and, if you plan to rent it out, what keeps the reviews up.
Checklist before signing on the Costa del Sol
Boiled down to a table, this is what should be settled before you hand over a deposit:
| What to check | Who does it | What it is for |
|---|---|---|
| Structure, roof and waterproofing | Qualified technical architect | Costing the works and negotiating the price |
| Damp: condensation or ingress? | A surveyor, not the seller | Avoiding a five-figure surprise |
| Wiring, plumbing and air conditioning | Installer or surveyor | Budgeting the first year |
| Community minutes, levies and ITE/IEE | Property manager / your lawyer | Not inheriting the building's debts |
| Tourist licence (VFT) if you plan to rent | Lawyer / your agency | Knowing whether holiday letting is viable there |
One point specific to Andalusia: if you plan to let the property to tourists, it must be registered as a Vivienda con Fines Turísticos (VFT), and a growing number of residents' associations restrict or ban the activity in their bylaws. Check this before buying, not after. And to know whether the asking price is in line with the market in Marbella, Estepona or Benalmádena, always cross-check the listing against our market report, with median prices by municipality and euros per square metre.
Conclusion
Buying a holiday home is decided with excitement, but signed with data. A technical report and a careful reading of the community's minutes cost little and prevent the one kind of surprise nobody wants in a holiday home: the unexpected bill. At EVS Property Group we guide the whole process, from the first viewing to the deed.
Frequently asked questions
Is it worth paying for a survey before buying?
Yes. It costs a fraction of the purchase price and usually pays for itself: either it uncovers a problem that stops you buying badly, or it gives you leverage to negotiate the price down.
Do I inherit the community's pending levies when I buy?
In practice, approved and unpaid fees and levies attach to the property. That's why the seller is required to provide a certificate confirming payments are up to date, and why the minutes are reviewed before signing.
Can I rent out my holiday home to tourists on the Costa del Sol?
It depends on the property. You need to register it as a Vivienda con Fines Turísticos (VFT) in Andalusia and check that the community's bylaws don't prohibit it. Verify this before you buy.
