Normally, a condemned property cannot be sold as property. The property can always be sold as land, even if the value is reduced due to the buyer's expenses of demolishing the condemned house and taking it, which makes it difficult for a buyer to obtain a mortgage loan.

You can sell a house as-is with the mold, however you have to reveal. In case of doubt, just reveal!. By selling a house with the mold as-is, the most likely buyer will be a cash buyer. Borrowers usually don't lend in the houses with the mold.

Owners can refuse the offer or sell the house without obtaining a full inspection of the house. Cases that have a clear need for repair are generally sold as is the case with a fair cash price that may be below market value.

You can sell the house at any price that a buyer agrees to pay, even if this price is lower than the market price of their homes. However, the sale of the house at a price lower than the market price does not exempt you from the obligation to satisfy all property rights.

To sum up If you are a home buyer, do not leave your dream home because you discover a small mold. If you are a buyer or a seller (or someone else for this question), the effects of the mold on health are often related to allergy and other symptoms are not often tested.
