I haven’t read everything now. So I apologize in advance if this is repetitive. When we bought our house, we didn’t receive many documents. This later turned out to be a problem years later: when we needed a building permit for a double carport. It turned out that half of our property, namely almost the entire garden, was actually supposed to be a planting strip that had to be planted according to the municipality's requirements and otherwise was not allowed to be built on or sealed. At that time, the entire garden including paths, garden house, play equipment, various beds, and trees that coincidentally did not match the planting plan had long been there. The shock was great. In the end, we were able to come to an agreement with the municipality and legalized our garden retroactively against a compensatory plan. The other thing: for the same permit, we needed proof that we had a right of way and utility easement for the property in front of us. Well, this was also nowhere documented. With the help of friendly neighbors, we were able to prove the right through their land registries. Because nothing is registered for us, which apparently is not uncommon. In all the fuss, I then obtained the building file, which unfortunately could not be found at the county building authority. Eventually, a very nice municipal employee found it on site in the basement... In short, there were several dramas, sleepless nights (do we have to get rid of the garden?!), and many lessons learned. The most important one: never again will we buy a house without documents. Building files, floor plans, and whatever else there is—I want to see that beforehand next time and have it checked externally if we don’t understand it. And next time I look at the development plan differently, because there was a small discreet line that I, as a layperson, did not understand. That turned out to be the planting strip. Maybe everything is okay with the house, but maybe not. I would want to protect myself as much as possible. Acquaintances of ours bought a house, also somewhat naively, and the upper floor is contaminated with harmful substances. Especially with older houses, even if they look okay/manageable visually, I would be cautious. Unless you have enough money for all contingencies and can (and are allowed to!) tear down and rebuild if necessary. For us at least, the price was only realistic for a demolition object.
