How can one find out if the property actually has a catch/defect? I am unfortunately completely inexperienced and have no technical or craft-related understanding.
That's how I had imagined it too. I will ask if the [gemeinde] will reserve it for us and then have an expert come. Yesterday I already contacted a few experts and asked for prices. One offer is currently €7,850 for 2 drillings. If they find oil, that's okay, but otherwise, I find that very expensive? What should such an expert report cost?
"Geotechnical investigation by 2 small percussion drillings with sufficient depth according to DIN EN ISO 22475 as well as their soil physical evaluation with simultaneous ground assessment and the preparation of a geotechnical short report flat rate. € 7850.- The price is exclusive of the currently applicable VAT."

Perhaps an oversight or serious intent to deter customers.
