Realtors do not have a duty to disclose conditions in a unit or home; it is the *seller* who has an obligation to disclose harmful or dangerous conditions of which he is, or reasonably should be (that is, under the circumstances, any seller in his position would logically know of), aware. If the seller can be shown to have either known or that he should have known of the aluminum wiring but despite knowing of it, did not disclose it, he may well have committed fraud; and fraud provides a basis to recover compensation (i.e. to sue for money).
