Monika Gruber in the dispute over Schimmelvilla: 2.5 million at stake!
There's a lot going on in the idyllic surroundings of Rottach-Egern: the popular Munich cabaret artist Monika Gruber has sued the heiress of her real estate seller. This occurs in connection with the reversal of a house purchase that was completed two years ago. Gruber is demanding an impressive 2.5 million euros for the villa, where she discovered dampness and mold in the basement after purchasing it. Apparently the condition of the property was not as rosy as first impressions suggested - during the inspection, Gruber only smelled a musty smell, which at the time was attributed to poor ventilation and old carpets, reports muenchen.t-online.de.
The dispute over the villa will be heard next Tuesday before the Munich II Regional Court. While Gruber accuses the seller of knowingly concealing the defect, the defendant heiress invokes an exclusion of warranty. This states that Gruber bought the house “as is”. In practice, this often means that the seller is not liable for defects, even if problems arise later. Buyers may have to expect damp walls or other structural damage that only becomes visible after the purchase, explained anwalt.de.
Hidden defects and their legal consequences
Anyone who buys a new home is often blinded by external beauty and overlooks hidden problems. The most common mistakes when buying real estate include damp walls and unnoticed mold growth - often hidden behind walls or insufficiently ventilated basement rooms. This damage can pose serious health risks, especially if discovered after purchase. Buyers should be aware of this and act promptly if defects are discovered after purchase: secure evidence, contact the seller and consider legal action if necessary. This applies in particular if hidden defects were fraudulently concealed, as may be the case in Gruber's case kanzlei-franz.com.
The legal basis for this is clear: an exclusion of warranty protects the seller, but there are exceptions if defects are intentionally kept secret. If, for example, moisture has been painted over or there are unauthorized additions, the seller can still be held liable. In the current case, the court could decide whether the seller is responsible for the mold in the basement, which Gruber did not want to accept, to her detriment.
It will soon become clear whether Gruber will get through with her lawsuit or not. However, one thing remains clear: buying real estate can be associated with a number of risks. Buyers should therefore always keep a close eye on possible hidden defects and, if in doubt, act promptly. Because in the end it is better to take another look than to experience unpleasant surprises in your new dream property.
