Earthquake risk in Spain: how to check before you buy a property in 2026

For most foreign buyers in Spain, "earthquake" sits in the same mental box as "tsunami" — a vague background risk somewhere on the news, irrelevant to the offer letter on a townhouse in Granada or a duplex in Lorca. That was a defensible position in 2005. It isn't one in 2026.

On 11 May 2011, a shallow Mw 5.1 earthquake on the Alhama de Murcia Fault killed nine people in Lorca, injured more than 300, displaced thousands and damaged or destroyed an estimated 7,800 buildings, including the bell tower of San Diego and a long list of 1960s–80s apartment blocks the building code on paper said should have survived. Total damages crossed €1.2 billion. It is the deadliest earthquake on the Spanish mainland in living memory and, for the country's seismologists, the closest thing to a textbook warning the post-NCSE-94 building stock had ever received.

Lorca was not a freak event. Between 2021 and 2023 a low-level swarm rattled the Vega de Granada for the better part of two years, with five quakes above Mw 4.0 felt in the city itself and superficial structural damage on around 200 buildings. In 2024–2025 a new swarm above Santa Fe and Atarfe ran through the autumn, and the IGN's tweets — once an obscure scientific feed — turned into a daily read for thousands of Granada homeowners. The 2021 La Palma volcanic eruption was preceded and accompanied by tens of thousands of seismic events, half of them felt, and destroyed nearly 1,700 buildings. El Hierro had its own underwater eruption a decade earlier. The Pyrenees moved, quietly but recurrently, throughout the 2020s.

If you are buying property in Spain in 2026 — particularly anything in Granada, Murcia, Almería, the southern Pyrenean foothills, the Canaries, or older apartment stock anywhere in the southern half of the country — earthquake risk belongs alongside the nota simple, the flood-zone check and the wildfire-risk check in your offer-stage due diligence. It is no longer a footnote; it is something that quietly moves the insurance premium, the structural-survey cost, the retrofit liability the buyer inherits with the keys, and — in a small but growing number of cases — whether the comunidad across the street has a pending €40k assessment on its 1972 reinforced-concrete frame.

This guide is the practical version. Where to look, what to look for, how to read the IGN hazard map, what your lawyer and surveyor should be asking, and what is starting to change in how Spanish insurers, banks and town halls price peligrosidad sísmica on an address-by-address basis.

If steps 1, 2 and 7 are clean for a post-2002 build, you can usually stop. For anything pre-1995, anything in zones with aceleración sísmica básica ≥ 0.08g, and any apartment block with a bajo comercial or open ground-floor parking, you escalate to 3, 4, 5 and 6, and you do not skip the structural survey.

What changed between Lorca and 2026

Spain has always had earthquakes. What changed is the density of the building stock in the active zones, the age of that stock, the scientific understanding of the faults that produce shallow damaging quakes, and — slowly — how the market and the insurers are pricing both.

Five shifts matter for buyers:

1. The Alhama de Murcia and Carboneras–Palomares faults are now properly mapped. Until the early 2010s, Spanish seismic hazard cartography blurred the active Betic faults into broad regional polygons. Post-Lorca, the IGN, the IGME and the universities (Granada, Murcia, Almería, UCM) mapped the surface traces, the slip rates and the recurrence intervals in detail. The 2015 Actualización de Mapas de Peligrosidad Sísmica and its 2022 working revision both raised the design accelerations for parts of Murcia, Granada and Almería — meaning the "official" risk of buildings in those zones is, on paper, higher than the building code under which the actual buildings were designed.

2. The 2024 revision of the NCSE has been stuck in consultation for years. The current building code is still NCSE-02, in force since 2002 and only lightly updated since. A draft replacement (provisionally NCSE-24) aligns Spain with Eurocode 8 (EN 1998), raises the design acceleration thresholds, and would meaningfully change the retrofit obligations for additions and reforms. As of mid-2026 it has not been adopted. What this means for a buyer is that the building you are looking at was designed to a code that the country's own engineers and the EU consider out of date.

3. The Vega de Granada swarms moved the local market. Between 2021 and 2025, two extended swarms rattled the metropolitan ring around Granada. No deaths, modest damage, but enough to put hairline cracks across thousands of plastered walls and produce a visible bid–ask spread on pre-1995 apartments in Santa Fe, Atarfe, Pinos Puente, Maracena and the western Vega. Asking prices on top-floor flats in pre-NCSE-94 blocks softened 5–10% versus equivalent ground-floor flats in newer buildings. None of this is in the national press; all of it is in the local acta of the comunidades de propietarios.

4. The Consorcio surcharge is becoming visible — for the first time in a generation. The Consorcio de Compensación de Seguros has covered earthquake damage as part of riesgos extraordinarios since 1954, with a tiny premium added to every home insurance line in Spain. For high-hazard postcodes, brokers are now showing the Consorcio recargo as a separate, larger line on the schedule, and a small handful of private insurers have begun rating the underlying daños propios premium up on poorly-constructed older blocks in zona sísmica. None of this is yet market-wide; all of it is the leading edge.

5. Mortgage underwriting is starting to read the IGN map. Spanish banks were never strict on seismic risk. Several now require an insurance quote before approval for older blocks in declared high-hazard términos municipales, and a handful have begun asking for the Libro del Edificio and the Informe de Evaluación del Edificio (IEE) as part of valuation for pre-1995 buildings in Murcia, Granada and the Alpujarras. Not most banks. Not most files. But more than zero, and trending upward.

For foreign buyers, the upshot is the same as with flood and wildfire risk: the asking price of a Granada or Murcia property in 2026 already reflects some of this — but rarely all of it, and almost never at the level of street-by-street, building-by-building nuance the IGN catalogue and a half-decent aparejador can give you in a morning.

Step 1 — The national seismic hazard map (IGN)

The single most useful free tool is the Mapa de Peligrosidad Sísmica de España maintained by the Instituto Geográfico Nacional (IGN). It expresses ground-motion hazard as the aceleración sísmica básica (a_b), a peak ground acceleration value with a 475-year return period, expressed as a fraction of g.

You access it through the IGN's online viewer (search "IGN mapa peligrosidad sísmica") and via the Servicio de Información Sísmica portal. The same values are tabulated by término municipal in Annex 1 of NCSE-02, which is the authoritative legal reference.

What to look at:

• a_b < 0.04g. Below this threshold the seismic code does not apply to ordinary buildings. Most of Spain — Galicia, the Cantabrian coast, Castilla y León, Madrid, the Catalan coast north of Tarragona, the Balearics — sits here. For practical purposes, you can treat seismic risk as negligible for new buyers in these zones.
• 0.04g ≤ a_b < 0.08g. Low but non-trivial. NCSE-02 applies to most building types. Examples: parts of Catalonia (Tarragona inland, parts of Girona), Aragón south, Castilla–La Mancha southern fringe, parts of Cádiz and Sevilla.
• 0.08g ≤ a_b < 0.13g. Moderate. NCSE-02 applies fully, with mandatory structural detailing requirements. Examples: most of Murcia, the eastern fringe of Almería, the western Alicante interior, parts of the Pyrenees, much of Málaga inland.
• 0.13g ≤ a_b < 0.20g. High. The Spanish "hot zone" for shallow damaging quakes. Examples: Granada city and the Vega de Granada, much of Almería province, the Alpujarras, the Lorca–Totana corridor.
• a_b ≥ 0.20g. Highest mainland values, concentrated in a narrow corridor between Granada and the Sierra Nevada foothills. Granada capital sits around 0.23g.

How to read it: enter the address or pan to the property, switch on the aceleración sísmica básica layer, and read the value for the término municipal and the barrio. The Annex 1 table in NCSE-02 is also published as a PDF — search "Anejo 1 NCSE-02 aceleración básica" — and is the document your aparejador will quote.

A nuance the layer does not show: site amplification. Soft alluvial soils — typical of the Vega de Granada, the Guadalentín valley around Lorca and parts of the Bajo Segura — can amplify ground shaking by a factor of 1.5–3 versus the bedrock acceleration. The map shows you the basic hazard; the soil under your foundations modulates what arrives at the walls. Your aparejador will translate.

Step 2 — The IGN earthquake catalogue

The Catálogo y boletines sísmicos at ign.es is the live record of every seismic event detected in Spain. You can search by date range, by magnitude, by radius around a coordinate. For a foreign buyer, the useful workflow is:

1. Centre a 25 km radius on the property coordinate.
2. Filter for events of Mw ≥ 2.5 in the last 25 years.
3. Look at the count, the maximum magnitude, the depth distribution and the temporal pattern.

What you are checking:

• Is there a baseline of microseismicity? A handful of Mw 2–3 events per year is normal background. Tens to hundreds within 25 km, year on year, indicates an active fault system at depth.
• Are there swarms? Clusters of dozens of events within days or weeks suggest the property sits over or near an active stressed segment. The 2021–2025 Granada swarms are textbook examples.
• Are events shallow? Spanish damaging quakes are almost always shallow (≤ 10 km). A Mw 4.5 at 5 km is felt much more strongly than a Mw 5.0 at 30 km. The catalogue lists depth.
• Has anything Mw ≥ 4.0 happened in the last decade? If yes, the comunidad de propietarios of any older block within the felt radius should have a record of post-event inspection. Ask for the acta covering the event.

The catalogue is free, in Spanish and English, and authoritative. It is the cheapest seismic due diligence on this entire list — twenty minutes, well spent.

Step 3 — The nota simple and registry affections

The nota simple rarely flags seismic risk directly. Unlike afección hidráulica or zona de policía, there is no standard registry entry that says "in a high seismic hazard zone". But three indirect entries are worth checking with your lawyer:

• "Inscripción del Libro del Edificio" — confirms (or doesn't) that the building has a registered technical file. For post-1999 buildings the Libro should exist; for pre-1999 buildings it usually doesn't. The Libro contains the structural design memo and, if any seismic retrofit was done, the certificado final de obra for it.
• "Calificación urbanística" for plots in declared zonas de actuación sísmica — a few Murcia and Granada municipalities now flag certain parcelas as inside the post-Lorca Plan de Actuación Especial frente al Riesgo Sísmico or the equivalent.
• "Afección por expediente de ruina" — a pending expediente de ruina (formal dilapidation file) on a building, or on neighbouring buildings, is a flag that quake-related damage may have been documented but not remediated. Common in older centres of Lorca, Granada (Albaicín), and parts of Almería capital.

What you want, more than a nota entry, is the Informe de Evaluación del Edificio (IEE) — the mandatory ten-year technical inspection that all residential blocks above a certain age (usually 50 years, with some regional variations) must hold. The IEE explicitly assesses structural safety and is the closest thing to a seismic-vulnerability statement in standard Spanish documentation. Your lawyer can request it from the Ayuntamiento — and if it is missing or unfavourable, that is information.

Step 4 — The build year and NCSE compliance

The build year is the single most important seismic data point a foreign buyer can extract about a property. The Spanish regulatory regimes, simplified:

• Pre-1968. No seismic code at all. Stone masonry, tapial, adobe, rubble walls, lime mortar. Performs catastrophically badly in shallow quakes; almost all the Lorca casualties were in pre-1968 stock. Many beautiful village houses and Granada cármenes fall into this category.
• 1968–1994. The first Spanish seismic norms (Norma MV-101, then NCSE-94 draft predecessors). Inconsistent enforcement, low design accelerations, and crucially — the typical 1960s–80s reinforced-concrete apartment with a bajo comercial or open-ground-floor garage is structurally a "soft-storey" building, the single most documented vulnerability pattern in modern damaging earthquakes worldwide.
• 1994–2002. NCSE-94 in force. Real seismic detailing on paper, with patchy quality control on site. Better than what came before.
• 2002–present. NCSE-02 in force. Modern, broadly Eurocode-aligned (though not as conservative as EC8). Apartments and detached houses built and inspected to NCSE-02 have performed well in the events Spain has had since.
• Post-NCSE-24 (when adopted). Designed to the updated draft. Will be visibly more conservative on detailing, expansion joints and muros pantalla.

How to find the build year: the Sede Electrónica del Catastro lists the año de construcción in the consulta descriptiva y gráfica — free, immediate. Cross-check with the nota simple and, if available, the building's Libro del Edificio. Be careful with reformed buildings: a reforma integral in 2008 of a 1965 shell is, structurally, still a 1965 building unless the memoria of the reform explicitly includes seismic strengthening.

Step 5 — The municipal PGOU and the regional plan

Each Spanish region runs an Plan de Actuación frente al Riesgo Sísmico under the national Plan Estatal de Protección Civil. The most developed are:

• SISMIMUR (Murcia). Post-Lorca, the Region of Murcia mapped every término municipal by vulnerability class and built explicit emergency-response protocols. Several Murcian towns now flag high-vulnerability buildings in the PGOU.
• SISMOAN (Andalucía). Covers Granada, Almería, Málaga, Jaén. Updated 2023.
• SISMICAT (Catalonia). Covers the Pyrenees and the Tarragona basin.
• Canarias. Volcano-seismic emphasis, with the PEVOLCA plan handling La Palma and Tenerife.

For a buyer, what matters in these plans is the vulnerability class assigned to the término municipal and, where published, the building-type inventory that backs it up. Some municipalities — Lorca, Murcia capital, Granada, Almería — publish street-level inventories with vulnerability ratings. Your lawyer or aparejador can pull them.

Equally important: the PGOU itself. Post-Lorca, several Murcian municipalities added seismic detailing requirements to all building licences and to reform licences above a threshold (typically > 25% of build area). If you are reforming a 1970s apartment in Lorca, Totana or Mula, expect the visado to require explicit seismic compliance for any structural touchpoints — a cost line foreign buyers regularly miss.

Step 6 — The structural survey

For anything pre-1995 in a zone with a_b ≥ 0.08g, commission a structural survey from an arquitecto técnico (or aparejador) with explicit seismic-vulnerability commentary. €350–€900 in most of Spain; €600–€1,200 for a detailed report on a larger building. This is the single most valuable spend on this list for older stock.

What you want the report to cover:

• Structural typology. Bearing-wall masonry, reinforced-concrete frame, mixed, tapial with later additions. The typology drives everything else.
• Soft-storey flag. Open ground floor, parking, commercial unit with no continuous walls — if yes, the building's seismic vulnerability is materially higher than the floor-area-weighted average suggests.
• Pounding risk. Two adjacent buildings of different heights or stiffnesses on a shared party wall, with no expansion joint between them. Common in Spanish cascos antiguos.
• Out-of-plane wall risk. Façades without effective tying to the slabs. Common in stone-masonry village houses and 1960s brick blocks.
• Visible damage. Diagonal cracks, displaced lintels, separation of cross walls, sloping or bowed walls.
• Documented retrofits. Steel ties, concrete jacketing of columns, fibre-reinforced polymer wraps, base isolation. Rare in residential stock but worth noting.
• Recommended remediation. With approximate cost ranges.

If the survey flags any of the above, you have a negotiation. If the survey is clean, you have a sleeping pill.

Step 7 — Insurance and the Consorcio

Earthquake damage in Spain is covered by the Consorcio de Compensación de Seguros as a riesgo extraordinario, funded by a small surcharge added to every home insurance line in the country. The Consorcio pays out for structural and content damage from earthquakes, tsunamis, volcanic eruptions, atypical cyclonic winds, floods and a handful of terrorism-related events. For foreign buyers used to standalone earthquake insurance markets (California, Italy, Greece, Japan), the Spanish model is unusual and worth understanding.

What this means in practice:

• You cannot buy a Spanish home insurance policy without earthquake cover. It is automatic, mandatory and priced collectively. Premiums in Granada are not visibly higher than premiums in A Coruña because of seismic risk.
• The Consorcio pays at valor de reposición. Replacement value, not market value, and only up to the sums insured on your policy. If you underinsure your continente (the structural value), you underinsure your Consorcio payout in a quake. Underinsurance is the single most common cause of disappointing Consorcio outcomes.
• The Consorcio surcharge is small but visible. As of 2026, around €0.08 per €1,000 of insured value for residential continente, with a recargo line on every schedule. For high-hazard postcodes, some brokers now break this out as a separate line; the underlying number is the same nationally, but visibility differs.
• Private insurer pricing on daños propios is starting to vary by seismic exposure. Quietly. A 1970s apartment in central Lorca with a bajo comercial is, in 2026, attracting noticeably higher quotes than a 2018 build in the same town. Get three quotes, compare the continente premium line by line, and ask about any recargos.
• Communal cover matters. The seguro de comunidad on an apartment block covers the structure of the building. Ask the administrador de la comunidad for the current policy, the insured continente value, and confirmation that it is at valor de reposición a nuevo. If a 1970s block in a Granada barrio is insured at a 1990 value, the Consorcio payout in a quake will be wholly inadequate. This is fixable, but only before you sign.

Step 8 — The regional picture

Spain's seismic risk is heavily concentrated in the south-east and a handful of pockets elsewhere. The headline picture, region by region:

Granada province

The highest-hazard region in mainland Spain. Granada capital sits at a_b ~0.23g. The Vega de Granada has soft alluvial soils that amplify ground motion. The historic 1884 Andalucía earthquake (Mw ~6.5–6.7, around Arenas del Rey and Albuñuelas) killed approximately 900 people and destroyed several Alpujarras villages. The 2021–2025 swarms have rattled but not damaged Granada significantly; the IGN considers a damaging event within the next century a working assumption rather than a possibility. Foreign buyers should treat Granada province as the highest-priority seismic-due-diligence region in Spain — especially for pre-1995 stock in the city centre, the Albaicín, the Realejo and the western Vega towns.

Murcia

The Lorca event of 2011 is the single most studied modern Spanish earthquake. The Alhama de Murcia Fault, the Bajo Segura Fault and the Carrascoy Fault all run through the region. Lorca, Totana, Alhama de Murcia, Mula, Murcia capital and the Mar Menor ring all sit in a_b zones of 0.10g–0.17g. Post-Lorca, the regional government invested heavily in retrofit programs and PGOU updates. For foreign buyers on the Costa Cálida and inland Murcia, the IGN catalogue and a pre-NCSE-94 build-year flag are the two screens that matter.

Almería

Almería province sits across two fault systems — the Carboneras Fault on the coast and the southern Alpujarras faults inland. The 1522 Almería earthquake (Mw ~6.5) destroyed much of the historic city. a_b in Almería capital runs around 0.12–0.14g; in parts of the Alpujarras up to 0.16g. For buyers in Mojácar, Vera, Roquetas and the Cabo de Gata coast — and especially for rural Alpujarras cortijos — seismic vulnerability of pre-1995 stone-masonry construction is the key concern.

Alicante

The Bajo Segura Fault produced the 1829 Torrevieja earthquake (Mw ~6.6, killed ~389). Modern a_b in the Bajo Segura runs around 0.12–0.14g — high enough that NCSE-02 applies in full. Foreign buyers concentrated in Torrevieja, Orihuela Costa, Guardamar and the Vega Baja should treat themselves as buying in moderate-seismic territory, even though the regional marketing rarely says so. The Costa Blanca guide covers the wider buying landscape; the seismic angle is the one that gets least airtime.

Málaga and the Costa del Sol

Lower hazard than Granada or Murcia, but not negligible — a_b in the Málaga capital runs ~0.09–0.10g. Several active faults run through the Sierra de las Nieves and the Estepona–Marbella corridor. Modern construction is broadly fine; pre-1980 town centre stock in Málaga, Marbella, Estepona and Ronda is the watch list.

Pyrenees

Moderate. The Catalan and Aragonese Pyrenees produce recurrent low-to-moderate magnitude events. a_b in the high Pyrenees runs around 0.10–0.13g. For buyers in Vielha, Jaca, La Seu d'Urgell and the Pallars, seismic vulnerability of older stone-masonry mountain houses is the concern; modern construction is well-handled by NCSE-02 and Eurocode 8 cross-references.

Canary Islands

A different risk profile. Classic tectonic risk is low, but volcanic-tectonic activity (Cumbre Vieja 2021 on La Palma, El Hierro 2011 underwater) produces extended seismic swarms with hundreds to thousands of felt events. Tenerife (Teide complex) and Lanzarote (Timanfaya) have potential. Buyers should consult the Plan de Emergencias Volcánicas (PEVOLCA) for the island, more than the classic IGN seismic hazard map.

The rest of Spain

Galicia, the Cantabrian coast, the Castilian meseta, Madrid, the Catalan coast north of Tarragona, the Balearics: low hazard, NCSE-02 generally does not apply to ordinary buildings, and seismic risk is not a meaningful screen for foreign buyers in these regions. Other things matter more — flood, wildfire, demographic decline, planning quality — and the region-by-region guides cover them.

What this means for an offer

When the maps, the catalogue and the build year all line up against you, you have four options. From cheapest to most drastic:

1. Adjust the price. A pre-1995 bajo comercial block in a a_b ≥ 0.13g zone with no IEE on file is a real property — but it should be priced 5–15% under an equivalent post-NCSE-02 build, or under a pre-1995 block with a documented retrofit and a current IEE. If the seller hasn't adjusted, you negotiate. Quote the aparejador's report and the communal-insurance shortfall.
2. Make a retrofit a seller condition. Steel ties, concrete jacketing on first-floor columns, a Plan de Conservación with the comunidad, an updated seguro de comunidad at valor de reposición a nuevo. These can be made completion conditions, with the seller bearing the cost, or with a corresponding price cut.
3. Buy a different unit in the same building. A top-floor flat in a soft-storey block is, in many quakes, the unit most likely to be uninhabitable post-event. A first-floor flat directly above the bajo is also exposed. Middle floors away from the corner columns generally fare best. Sometimes the cleanest answer is the same building, a different unit.
4. Walk away. Some properties — uninspected pre-1968 tapial houses on amplifying soils in a_b ≥ 0.16g zones, with cracked façades and no Libro del Edificio — are not the right buy at any price, however charming. Trust the engineer and the insurer. If the aparejador says no, you say no.

What your lawyer and surveyor should be doing

A competent Spanish property lawyer in 2026 includes seismic-zone due diligence as standard for purchases in Granada, Murcia, Almería, the Alicante interior, and parts of Málaga and the Pyrenees. If yours doesn't, ask. Specifically:

• Confirm the aceleración sísmica básica for the término municipal from NCSE-02 Annex 1.
• Pull the Libro del Edificio and the most recent Informe de Evaluación del Edificio from the Ayuntamiento.
• Cross-reference the build year on the cadastral file with any documented reforms — and flag any structural touchpoint reforms that should have triggered seismic compliance under the PGOU.
• Confirm with the administrador de la comunidad that the seguro de comunidad is at valor de reposición a nuevo and includes adequate continente coverage.
• Read the last three actas of the comunidad for any mention of post-event inspection, structural assessment or pending derrama for structural works.

The aparejador covers the structural side. Together, a 2–3-hour add-on to a normal title check, well within the 1% lawyer fee you are already paying — plus the €350–€900 for the structural survey. The cost of not doing it can be life-altering, and is much more probable than the foreign buyer's mental model suggests.

Where this is heading

Three trends to plan for if you are buying for the long term:

1. NCSE-24 adoption. The current draft is broadly aligned with Eurocode 8 and raises the design acceleration thresholds. When adopted (most likely 2026–2027), it will quietly upgrade the retrofit obligations for any reforma estructural above a threshold. Properties grandfathered into NCSE-02 will face stricter standards on their next major reform — which is a real cost line if you are buying a 1970s flat with the intention of redoing the structure.
2. Insurance segmentation. Like flood, the Consorcio model is solidarity-based and will hold for the structural cover. But private insurers are starting to vary the daños propios line by exposure, and the gap will widen. Expect annual home insurance to become a real comparator line for older blocks in high-hazard postcodes, not a rounding error.
3. Municipal regulation. Several Murcian and Granadian municipalities have moved or will move from advisory to actively requiring the Informe de Evaluación del Edificio and structural-assessment certificates before transactions on older buildings. Lorca led; Granada, Murcia capital and Almería are following. Buyers should expect the document set required for completion to grow over the next five years.

None of this is a reason to avoid Granada, Murcia, Almería or the Alicante interior. The southern Spanish quality of life, the prices, the light and the food are not on offer in lower-hazard regions. It is a reason to do the twenty minutes with the IGN catalogue, the half-hour with NCSE-02 Annex 1, and the morning with the aparejador, on every shortlisted property before you fall in love with the patio.

Where Buvivo fits in

This is the kind of work that is much easier to do on five shortlisted properties than on five hundred portal listings. Most foreign buyers waste weeks scrolling Idealista, Fotocasa and Pisos.com without ever reaching the due-diligence stage, and arrive at the IGN map only after they have already paid an arras deposit.

On Buvivo, you post your criteria — including, if you want, "post-NCSE-02 build, no bajo comercial soft-storey, IEE current, seguro de comunidad at valor de reposición a nuevo" — and matching agents pitch you properties that already pass your filter. You spend your time on the maps, the lawyer and the aparejador's report, not on the funnel.

For the rest of the process, the foreigner's guide to buying property in Spain covers the full sequence, the red flags guide covers what else to look for, the flood-risk guide and the wildfire-risk guide complete the natural-risk trilogy, and the hidden costs guide tells you what a structural survey, an updated communal insurance line and a future NCSE-24 reform actually add to year-one ownership.

Twenty minutes with the IGN catalogue is the cheapest decision tool in this entire guide. Do it before, not after, the offer.
