At home or abroad. Land, an off-plan build or an existing house. Within 48 hours you know whether your project holds up.
Pick the line that applies to you. Behind it sits exactly what needs checking in that situation.
Price, substance, permits and contract before any money moves. This is the standard case and the moment a check is worth the most.
See the property check →Payment plan against construction progress, specification, completion security. Before the transfer, not after.
Have the developer checked →Structure, damp, roof, building services and a realistic renovation depth based on photos and drawings.
Have the existing house checked →Each of these can cost five figures. None of them shows up on a viewing with an agent and good weather.
Whether land, a developer project or an existing house: within 48 hours you get a structured report with a traffic-light rating and a clear recommendation. Buy, renegotiate or walk away.
Developer reputation, specification, payment plan and permits. Does the promise hold up technically?
Details →Structure, materials and services from photos and drawings, plus a realistic renovation depth.
Details →Not the property but your health inside it: air, mould, pollutants, materials, radon. With a traffic light and an action plan, for existing buildings and new builds.
Benjamin Fercher comes highly recommended. He gave me a precise and understandable analysis of the property in question, and precise advice on what to do to remove the defects. And what counts a lot: this is not someone who just takes the client's money and delivers something cheap, but someone who does his job with judgement, deep expertise and real care.
I would advise anyone buying a property to get Benjamin's opinion. Absolutely excellent and deep analysis of the structural risks and the legal background. In my view the investment in Benjamin saves a lot of unnecessary extra cost later.
You send me an email with the property and the documents you have.
I check whether everything is there. If something is missing, I tell you what you still need.
Within 48 hours you get your traffic-light report with a clear recommendation.
The invoice of 750 EUR follows after delivery.
No site visit. No structural recalculation. No legal advice. No dealings with authorities. The check is a founded risk assessment based on the available documents and 15 years of building projects, not a substitute for a local lawyer or surveyor. If you need both, the report says so.
Every check follows the same grid, from completeness of documents to the traffic light. That makes visible what stays invisible on a viewing.
Completeness check, first risk indicators.
Title, land register, development law, country-specific risks.
Reputation, payment plan, bank guarantees, snagging clauses.
Structure, damp, roof, facade. And plausibility: the listing against the objective finding.
Site suitability, building physics, breathable build-ups, regional material choice.
Follow-up costs over 5 and 10 years, renovation forecast, resale prospects.
Traffic light GO, CONDITIONAL or NO-GO with reasons. Plus concrete levers for renegotiation.
Not a loose PDF with a few phrases but a structured document of 9 to 13 pages: traffic-light overview per check point, detailed analysis, a counter-calculation of the yield, a location profile and a clear recommendation at the end. Three real, anonymised pages from a delivered report on an off-plan project in Bulgaria.
Agents, developers, architects, trades: all of them earn on your build. I am the only one at the table who does not. My business model is that you pay me for the judgement.
I take no money from agents, developers or sellers.
I recommend materials by suitability, not by sponsorship.
I check projects, I do not sell them.
I do not trade building materials and earn nothing on your order.
These markets have their own pages with the local specifics: registers, permit routes, typical construction and the mistakes that keep happening there.
The index records, for 59 developers and 305 projects across ten countries, what is publicly documented and what is not. No score, no traffic light, every entry with its source.
Your country is not listed? It still gets checked. Building physics and contract risk follow the same principles everywhere, and I research the specifics for your location.
Why payment plans abroad hang on calendar dates instead of construction progress.
What goes wrong in almost every case that lands on my desk.
The items that appear in no budget and still always arrive.
Lawyer and tax adviser cover the paperwork. Nobody checks the substance.
Clay houses from the 18th century are still standing. Developer blocks from the 1980s are being torn down. Modern building substance is no longer planned for generations but for thirty to fifty years, and that is not an oversight but a business model.
The question I ask owners and buyers is simple: what is your house made of, and how will it age? The answer is not in the marketing material, not in the specification and not in the contract.

Master builder and civil engineer from Austria. 15 years on sites, in design offices and in independent advisory, more than 120 million euros of project volume. I have built houses from timber, clay and stone, and I have seen projects fail on the wrong materials, over-complex technology and missing control.
My approach: substance before technology, building physics before gadgets. Breathable, climate-appropriate construction instead of over-engineered systems that need servicing after five years and are electronic waste after ten.
Core markets: Austria, Portugal, Cyprus, Spain, Italy, Greece, Thailand, Namibia, the Philippines. And anywhere else you want to buy or build.
31 pages of plain talk: the most common mistakes when buying property abroad, checklists, traffic-light system and a risk matrix by country. The guide my clients get before they book me.
One email with the listing, the location and the documents you have. I come back within 24 hours on whether everything is there. 48 hours after that you have your report.
