Buying a house abroad starts with a dream and, surprisingly often, ends with a six-figure lesson. Not because the country was wrong or the idea bad - but because basic checks were skipped that would be a given in Austria or Germany.
I am a civil engineer with over 15 years of experience and review property projects worldwide. What I see keeps repeating - the same mistakes, the same patterns, the same expensive consequences.
1. You trust the seller instead of an independent check
The most common and most expensive mistake: the agent shows you a house, you fall in love, and suddenly you are signing a purchase contract in a language you do not speak, under laws you do not know.
The problem is not the seller. The problem is that no one at the table represents your interests. The agent earns the commission. The notary certifies but does not advise. The developer wants to sell. You are the only one without expertise - and at the same time the only one who pays.
An independent property check costs a fraction of what an overlooked defect will cost you. In my reviews I regularly uncover problems that put the purchase price into perspective by 20 to 40 percent.
2. You check the price, but not the building fabric
Many buyers compare price per square metre, research locations and negotiate the purchase price. What they do not do: have the building fabric checked.
A house in southern Europe with cracks in the facade, a damp cellar and a leaking flat roof can look cheap on paper. In reality it hides renovation costs that completely eat up the supposed price advantage.
I have reviewed properties where the renovation would have cost more than a new build. Not because the house was old - but because it was badly built. And that difference cannot be seen with the naked eye.
3. You do not know the local building rules
Every country has its own rules. What needs a building permit in Austria may be permit-free in Portugal - or vice versa. Plots with sea views zoned as agricultural land. Houses built without a permit. Servicing that is promised but never delivered.
In Paraguay, for example, a barrio privado needs the so-called Propiedad Horizontal so that you as a buyer even get your own land-register entry. Without this procedure you only have a private contract - no publicly registered ownership guarantee. Such details decide whether your investment is secured or built on sand.
4. You pay everything at once - without a milestone plan
In serious project development it is standard to tie payments to construction progress. A first instalment on the land purchase, a second on proven servicing, possibly a small final instalment on handover.
What I see instead: purchase contracts demanding 100 percent payment within 30 days - before a single metre of road is built. No deadlines for the developer, no penalties for delay, no right of withdrawal for non-performance.
If the developer has your money and no contractual obligation to use it on time, you are entirely dependent on his goodwill. That is not a deal - that is hope.
5. You confuse yield promises with security
“Guaranteed double the price in three years.” Such statements sound tempting. The question no buyer asks: who guarantees that - and with what capital?
A developer with 120,000 euros of share capital who issues yield guarantees over millions cannot honour that guarantee if the market does not play along. In the worst case you are part of a model that depends on the inflow of new investor money.
Yield comes from proven value creation - not from a promise in the contract.
What you should do instead
Before you sign, have the project checked by someone who does not earn from the sale. Someone who knows the building fabric, understands the contract structure and can assess the local conditions.
My property check gives you exactly that: an independent analysis with a clear traffic-light rating - within 48 hours, for 250 euros. No sales pitch, no commission, no conflicts of interest.
