Recently, a friend told me that when she sold her home in Scarsdale a few years ago, her agent told her to keep her windows open during the radon test. This would ensure the house would not fail the test and the deal would not hit an obstacle. The Seller did not listen to the agent. This is called FRAUD. While, in New York, a Seller is not required to disclose issues with a house, the Seller cannot actively conceal them. It is better to risk having to put in a mitigation system for a few thousand dollars to get the deal done, than risk being sued at a later date and, more importantly, putting an unwitting buyer at risk. Sellers, if your agents suggest you take actions to falsify your radon tests, you should report them to the local realty board. Remember, you were a buyer once too and perhaps they represented the seller at your peril.
For all Buyers, Sellers, and Homeowners, below are links to the EPA’s guides to Radon.
