If the inspection uncovers something big – and the seller refuses to fix it, it’s worth reminding them that they MUST disclose this to future buyers.
This won’t be a consideration on easy fixes… but lets say there’s mold, or significant water damage… The house is now much harder to sell without these items remediated.
For some reason the sellers agents don’t always convey this to the sellers unless prompted. And I’ve seen sellers reconsider when they realize they need to fix or disclose to any new buyers.
