Buying property in Spain: what to check, area by area
Each coast has its own risks: earthquakes in the Vega Baja, wildfires on the Costa del Sol, flash floods in Mallorca, houses on rustic land in Almería. Official data by town and the checks to make before paying a deposit.

Many buyers think they can check it all themselves. In practice the data is spread across the Cadastre, the Land Registry, the Ministry for the Ecological Transition, the Nuclear Safety Council, the National Geographic Institute, regional planning and town halls, each with its own maps and its own language. Missing just one can cost far more than the house's renovation.
Legal status and land
- Cadastral use (is it legally a home?)
- Planning classification of the land

- Minimum habitable floor area
- Building inspection status (ITE/IEE)
- Land Registry: owner, mortgages, seizures, easements (Land Registry Study)
Natural hazards
- River flooding (100-year flood zone)
- Sea and coastal flooding
- Wildfire: forest next to the house
- Wildfire history of the area
- Areas burned in recent fires

Installations and surroundings

The house and the price
- Real square metres vs the listing
- Age of the building and its parts
- Estimated renovation cost
- Asking price vs real sales nearby
- Indicative price range

- Annual costs (IBI, community, waste)
- Facade photo and official record
The one you forget is the one that matters: a power line behind the garden, a macro-farm just down the road, a vacant plot next door where a block will go up, a ravine that floods once every few years, or a "villa" that the Cadastre doesn't record as a home. Hogarfax checks all of them for the exact property, with the official source of each one.
Why check by area and then by house
Town averages tell you what to look for; only the exact plot tells you whether it affects your house. Use these guides to know the questions, then run a Hogarfax report on the property you like — in English, with 30+ official checks, before you pay a deposit.
