What we analyze in every property
We analyze every home from six different angles: the physical state of the building, climate risks, planning rules, natural risks, surroundings and price context.
Property condition
The age of the building and its technical condition determine how much maintenance you will need and which rules apply.
Building age
The construction year places the home in a specific building era (pre-1960, development boom 1960–80, pre-CTE 1980–2006, post-CTE 2006+). Each era has different implications for systems, regulations and renovation cost.
Technical building inspection
From a certain age (30–50 years depending on the municipality), periodic technical inspections are mandatory. We check whether the building is up to date with that requirement.
Minimum habitability surface
Spanish law allows the sale of homes of any size, but each region sets indicative minimums (36–40 m² on average). We compare the registered surface in the Cadastre with those thresholds.
Visual maintenance signals
We collect observable signs of deterioration: cracks, damp, leaks and facade issues. It is not a structural diagnosis, but it is an early indicator of what to inspect.
Climate
Climate is more than comfort: it acts on the materials in the home. Water, ice, extreme heat and wind have direct consequences for maintenance and breakdowns.
Days with >10mm rain / year
Heavy rain puts pressure on roofs, joints and material transitions. In areas with many intense events, leaks and damp problems are more common.
Days with maximum temperature ≥35°C
Extreme heat expands and contracts materials, degrades waterproofing membranes and shapes summer cooling costs. In hot areas, orientation and insulation are not small details.
Days with minimum temperature ≤0°C
Freezing water can burst pipes and freeze-thaw cycles crack porous materials. In areas with many frosts, exterior plumbing deserves a specific review before buying.
Annual average (%)
High humidity favours condensation, staining and mould. In poorly insulated buildings, it can condense inside the envelope, damaging insulation or rotting wood without being visible.
Days with gusts ≥55 km/h
A calm-day visit tells you nothing about how the property behaves in wind. In windy areas, loose tiles, poor windows and badly fixed roof elements are the first to suffer.
Land use and restrictions
Zoning and public-domain buffers determine what you can do with the property: build, extend, renovate, or nothing at all.
Land classification (SIU)
Urban, developable or non-developable land. It defines whether you can build, extend or whether it is forbidden. The Cadastre does not always say this — the Urban Information System (SIU) does.
DPH — Public Hydraulic Domain
If the home is near a river, protection strips and easements limit what you can do: you cannot build there and renovations may be restricted. This affects value and use.
DPMT — Maritime-Terrestrial Public Domain
Coastal proximity implies restrictions similar to rivers: channel, easement and police zone. In many coastal homes, these strips shape renovations and extensions.
Proximity to high-voltage lines
A nearby power line means easements for building (you cannot build in the strip), market-price pressure and electromagnetic fields. Three real factors the listing never mentions.
Physical risks
Natural hazards that can affect the home: water (flooding), radioactive gas (radon) and seismic activity.
Fluvial flood risk
More than 2 million Spanish homes are in flood-risk areas. We verify whether the property lies in a hazard zone according to MITECO maps (T100 return period).
Marine flood risk
Homes in coastal areas with marine flood risk (storms, sea-level rise, surge). MITECO data identifies the affected areas.
Radon concentration in the area
A natural radioactive gas and the second leading cause of lung cancer in Spain. Since 2025, measurement is mandatory for businesses. We show whether the area has risk potential according to the Nuclear Safety Council.
Seismic hazard in the area
NCSE-02 classifies the territory by basic acceleration (ab). We indicate whether the home is in a low, moderate or high seismic hazard area so you can inspect the building with the right criteria.
Surroundings and nuisances
What surrounds the home affects quality of life, health and value: noise, air pollution and industrial activity.
Proximity to an industrial zone
A nearby industrial estate can be Amazon or a chemical plant. The map does not distinguish. We indicate whether industrial land is classified, along with distance and direction, so you can investigate what type of industry it is.
Distance to motorways and main roads
Road traffic causes 80% of environmental noise. For every extra decibel, home prices drop by 0.64% on average. We indicate proximity to roads with high traffic volumes.
Proximity to an airport / aircraft noise
Living under an approach path or inside an airport noise contour affects sleep, health and property value. We use official noise-contour data.
Proximity to railway / train noise
Commuter rail, regional trains or freight services generate noise and vibration. It affects rest and wellbeing. We indicate proximity to lines with regular service.
Price and market
Value context: how much per m² in your area, market dynamics and price history.
Buying and selling activity in the area
A signal of whether the market in your area is growing, stable or contracting. Based on volume and price of recent transactions. It helps you judge whether buying now makes sense.
Final price in similar transactions
The price paid by other buyers for comparable homes in your area in the last 3 months. It is not a valuation, but real market context.
Cost per m² of land (plot)
Land value varies a lot by area. We show the cadastral plot price per square meter so you understand what you are paying for location.
Total built cost per m²
The final price you paid (or the seller asks) divided by built square meters. It lets you compare homes of different sizes in the same area.
