As-is changes negotiation, not disclosure. A buyer's home inspection, usually $400 to $600, still happens in most as-is sales, and it still gives the buyer grounds to walk away or renegotiate during their condition period if it turns up something serious, even though you have not promised to fix anything.
What as-is actually buys a seller is certainty going in: no repair negotiations after the fact, and a price that already reflects the home's real condition rather than one built on promised fixes that could fall through.
Pricing an as-is sale correctly from the start avoids the back and forth entirely. Get your hand-reviewed valuation from Joel Dyck.
