Does a home seller have to disclose the property’s condition in New Hampshire?

In New Hampshire, there is no general condition statement, but before a purchase contract for property with a building is signed the seller must give the buyer, who signs a copy, the statutory radon, arsenic, lead, PFAS and flood notice and written information about any private water supply and sewage disposal system, and for a one- to four-family home the seller must also disclose in writing the insulation, whether the property is in a federally designated flood hazard zone and any residential heating oil underground storage tank. A seller who does not know information required about the water supply or sewage system must say so in writing. A seller who knows that methamphetamine was produced on the property must disclose it in writing before the agreement is signed, until the property is determined to meet remediation cleanup standards, and a condominium seller must tell the buyer in writing of the right to obtain the association’s documents. The radon, arsenic, lead, PFAS and flood notice section says it creates no liability for the seller or seller’s agent for failing to give it. Federal law separately requires a lead-based paint disclosure when selling most homes built before 1978. This is RSA 477:4-a, 477:4-c, 477:4-d, 477:4-f, 477:4-g.
