Property & location · Assessment + ground verification

Property & location risk assessment.

An address is a decision — and most are made on a listing and a map. Aegilo assesses what neither shows: the immediate environment, access and egress, hidden hazards, and how a location behaves under stress. Desk analysis backed by discreet, lawful ground verification in Switzerland.

For private clients and family offices buying or relocating, and for organisations assessing a site or a portfolio. Swiss-based and founder-led — a redacted sample assessment goes out with the reply to your enquiry.

What the listing doesn't show

A valuation tells you what it's worth. A survey tells you what condition it's in.

Neither tells you whether it's the right place for your family or your operations. We assess the location as it actually is — five layers, none of which appear in the particulars.

IMMEDIATE ENVIRONMENTStreet and neighbourhood conditions as they actually are — day and night, weekday and event-day, not as a photograph taken at eleven on a Tuesday morning.
ACCESS & EGRESSRoutes in and out, practical travel times rather than map estimates, and what happens to both when the main road is closed.
EXPOSUREFlood, landslide and environmental risk; crime patterns; disruptive infrastructure; the construction and development already scheduled to change the area.
DEPENDENCIESProximity and reliability of the things a household or a site leans on — schools, hospitals, transport, emergency services.
PRIVACY & VISIBILITYWho can see, approach and observe the property, from where, and how easily.

Every finding traces to a source. Where it matters, we don't rely on sources at all — we go and look.

For private clients & family offices

Due diligence for the largest decision most families make.

On a CHF 2 million purchase, buyers routinely spend tens of thousands on transfer costs and a few thousand on a building expert — for the structure. Almost no one applies the same discipline to the location itself: the thing that can't be renovated.

PRE-PURCHASE LOCATION ASSESSMENT

Before you commit, not after.

The neighbourhood, access, exposure and dependencies behind one specific property — read while the decision is still open.

RELOCATION INTELLIGENCE

Districts compared, not brochures.

Districts or towns weighed against your family's actual requirements: schools, commutes, healthcare, privacy, security. The comparison, with the reasoning attached.

GROUND VERIFICATION

Somebody goes and looks.

Discreet, lawful on-site observation in Switzerland: how the street behaves at night, whether the advertised characteristics are accurate, what the photographs were framed to exclude.

RESIDENCE MONITORING

The picture kept current.

Continuous watch over the developments that affect your home — planned construction, zoning changes, emerging local risks — with a sourced note when something moves.

Aegilo Monitoring

Delivered discreetly — directly, or through your family office, bank or relocation adviser.

For organisations

From a single site to a portfolio.

Organisations face the same question at scale: which locations expose us, and how much?

SITE ASSESSMENT

Before acquisition, lease or occupation.

Location due diligence on a single address — the surroundings, the approach, the dependencies, and what changes at which hours.

PORTFOLIO SCREENING

A structured first pass across your addresses.

Ranks exposure and identifies the sites that justify deeper investigation. Scoped individually.

PRIORITY-SITE MONITORING

The assets that matter most, watched continuously.

Standing coverage of the sites you can least afford to be surprised at, with the triggers agreed in writing before it starts.

Aegilo Monitoring
GROUND VERIFICATION

When the desk picture isn't enough.

Discreet, lawful on-site validation in Switzerland — the same observation standard as the private work, pointed at a site rather than a home.

The result is a defensible answer to “which of our locations should we worry about, and why” — with the documentation to show the work was done.

Why Switzerland

Global reports end where our work begins.

International risk vendors can score a country. They can't tell you how a Vaud street behaves on a Saturday night, whether the “quiet neighbourhood” borders a planned construction site, or whether the ten-minute drive to the hospital is ten minutes in winter.

Aegilo is Swiss-based. We combine open-source analysis with local knowledge and discreet, lawful observation on the ground — a level of verification no remote provider can offer here.

Outside Switzerland the desk work travels; the ground work usually doesn't. Which of the two you're buying is agreed in writing before anything starts.

The deliverable

One document, built for one decision.

01

The location, assessed and sourced — every finding traceable to the document or the observation it came from.

02

Findings from ground verification — what was seen on site, with photographs where they carry the point.

03

Exposure and hazards, rated — each with the confidence level attached, so you can weigh the weak ones differently.

04

Access, egress and dependency analysis — routes, times, and what the address leans on to work.

05

What we could not verify, declared — named as unverified rather than smoothed into a confident sentence.

06

A clear conclusion — proceed, proceed with conditions, or reconsider — and the reasoning behind it.

PROCEEDNothing found that should change the decision — and a plain statement of what was examined in order to be able to say so.
PROCEED WITH CONDITIONSThe address works if something is handled: a route changed, a survey commissioned, a question put to the commune in writing before you sign.
RECONSIDERWhat we found is material enough that we would not buy it, with the reasoning set out for you to argue with rather than a verdict to accept.

Fixed scope. Fixed price. Delivered on a committed date. A redacted sample goes out with the reply to your enquiry.

This is not a building survey and not legal due diligence — nothing here assesses the structure, the title or the deed, and we don't drive, escort, staff or coordinate anything on the ground. Use it to decide which addresses deserve a surveyor and a notary, not instead of them. Where you need operational capability, we say so and make introductions.

Pricing

Published, so you can weigh it before you write.

LOCATION ASSESSMENT

from CHF 2,500

The core read on one address, including discreet, lawful ground verification in Switzerland.

FULL ASSESSMENT

from CHF 4,500

Deeper investigation, extended observation, and comparison of alternatives where the decision is between addresses rather than about one.

RESIDENCE OR SITE MONITORING

Per location, continuous, with the triggers agreed before it starts.

PORTFOLIO SCREENING & PROGRAMMES

Scoped individually.

Several addresses, or a standing programme across a portfolio — priced against the number of sites and how far the work goes.

Starting points, not a menu. Scope, turnaround and price are confirmed in writing before any work begins — and if a shorter piece of work answers your question, we say so.

Before you engage anyone

The questions you should be asking — ours, answered.

These are the things worth demanding in writing from any location analyst before you commit, including us. Where our answer is a limitation, it's written as one.

What data does an Aegilo property assessment actually use?

Public primary sources, read per engagement and named per claim in the deliverable. In Switzerland that means: federal police crime statistics at commune level rather than the cantonal aggregate, which averages a city and its villages into one number; cantonal natural-hazard maps grading flood, landslide, rockfall and debris flow; the cadastre of public-law restrictions (RDPPF), including consultation perimeters set under the ordinance on major-accident protection (OPAM); the commune's own zoning plan, revision schedule and public-inquiry notices; official school performance data with capacity and catchment rules; and the building's insurance claims history where it is available. Alongside that we run a maintained corpus of events and claims built from graded sources — ACLED, curated regional channels, news and official feeds — which supplies the surrounding picture rather than the parcel detail. Coverage is deepened for the geography you are actually asking about, as part of scoping: we would rather stand up the sources for one commune properly than claim a pre-built map of everywhere. Outside Switzerland the registers differ, and the deliverable says which we could reach and which we could not.

Is the assessment specific to the parcel, or to the area?

Both, and the deliverable says which is which for every claim. Hazard grading and RDPPF restrictions are read parcel by parcel. Crime baselines, fiscal load and school catchment are commune or sector level, because that is the granularity at which the data exists — reporting them as if they were parcel-specific would be inventing precision. Where a sector-level reading drives the conclusion, it is marked as a sector-level reading.

Does the assessment include someone actually going to the address?

In Switzerland, yes — ground verification is included in the location assessment rather than quoted as an extra. It means discreet, lawful observation: walking the routes at the hours you would really use them, seeing how the street behaves after dark, and recording what the listing photographs were framed to exclude. It is observation of a place from where anyone may lawfully stand, not surveillance of individuals, and we do not enter a property without the owner's permission. Outside Switzerland, ground verification is fielded by engagement: where the assignment supports it, we brief an advance team on precisely the gaps our desk analysis needs closed, and their observations enter the deliverable as ground-confirmed findings. Where we cannot put someone on the ground, the deliverable says so rather than implying a visit happened.

Is this a substitute for a building survey or legal due diligence?

No, and it is not intended to be. Nothing in this work assesses the structure: no engineer, no technical inspection, no verification of title, servitudes or the deed. It assesses the location — what is measured around the address, what is already scheduled to change, how it behaves under stress, and what a routine there would expose. Use it to decide which addresses deserve a surveyor and a notary, not instead of them.

How are findings graded, and what happens to what you can't confirm?

We separate who said something from where it appeared, and count independent named originators rather than articles — four outlets reprinting one wire story is one source, and it is counted as one. Support is then labelled: corroborated where independent originators agree, amplified where one originator has simply been repeated, single-source where there is only one, and contradicted where they disagree. A single-source finding ships labelled as single-source rather than smoothed into a confident sentence. One limitation worth stating plainly: where the decisive documents are cartographic, a desk read of a published map is an inference until the commune confirms it in writing. Any buyer can put that one-letter question to the urbanism service, and we say when it is the question that matters.

You use AI. How do I know it hasn't invented something?

Because a citation here points at a document we hold, not at a model's recollection of one — the source is fetched and kept, so a claim can be checked against the thing it came from. Every model call is logged with the model used, the prompt, the response and its hash; a build test fails if any code path skips that log. And the system is not permitted to promote a publication into an originator or manufacture agreement between sources — those guards can only ever weaken an attribution, never invent one. What you should not accept from us, or anyone, is a probability: we don't publish invented odds, and a judgement arrives as words with the reasoning attached.

What does it cost, and how long does it take?

A location assessment starts at CHF 2,500, including Swiss ground verification. A full assessment — deeper investigation, extended observation, comparison of alternatives — starts at CHF 4,500. Residence or site monitoring starts at CHF 350 per month per location. Portfolio screening and standing programmes are scoped individually. Those are starting points rather than a menu: the figure moves with how many addresses are in scope, how far the ground work goes, and how fast you need it. What is fixed is the sequence — we scope the question, then state the deliverable, the turnaround and the price in writing before any work begins. If a shorter piece of work answers what you came for, we say so rather than sell you the larger one.

Check the method before you ask

You don't have to take the sourcing on trust.

The answers above describe how a location gets sourced and graded. The Brief has been doing it in public every week — the same attribution, and the same habit of recording what changed rather than restating what was already believed. nineteen editions are published and dated, each naming its sources and recording what changed since the last one. Read one before you write to us.

A Brief edition shows the method, not the deliverable — it is a weekly watch, not a client report. For a sample of the report itself, ask: we send one with the reply.

How your data is held

You're telling us where your family will live. Nobody else gets to read it.

Most firms treat this as a legal appendix. For an intelligence firm it's part of the product: the question you asked us is itself confidential, before any answer exists.

SWISS STORAGE Your material sits in Switzerland. Stored with a Swiss provider under Swiss jurisdiction. US hyperscalers were excluded for storing client material on purpose.
KEYS HELD APART The people holding the data can't read it. Your material is encrypted under a key belonging to you alone, and that key lives in a different control domain from the storage.
ERASURE IS ONE ACT Deletion that actually reaches the backups. Erasure destroys your key, which renders every copy unreadable at once — archives included. Deleting rows can't promise that honestly.
