Hi Wolf -- I'm sorry you are so stressed about this. I lived in a lovely house for 15 years that got water in the basement. Built in late 1940s. The entire neighborhood was the same. It's very common in older homes. We did some upgrades ourselves with drainage, new walls, etc. We still had seepage. We removed rugs, had all items on some footing or raised a bit, nothing that could get damaged. We had dehumidifiers. Fans. We made it work. My spouse had an office in the basement. My brother even lived in our basement for a few years. It was nothing fancy but it was perfectly fine. When we sold the house we disclosed "seepage after heavy rain." We sold it 2 years ago with no problem.
