A seller's property condition disclosure statement, where one is provided, sets out known issues in writing, though it is not a substitute for a home inspection, which typically runs $400 to $600 and catches what a disclosure form does not. Ask for both before you rely on either alone.
For a showing itself, confirm you are touring with the licensed agent who booked the appointment, not a stranger who happened to be at the home when you arrived, and avoid touring a vacant or for-sale-by-owner property alone if anything feels off.
If something about a showing feels wrong, trust that and leave. Get your hand-reviewed valuation from Joel Dyck.
