Financing readiness is the second piece. A buyer who has mortgage pre-approval sorted before shopping can move confidently on a fairly priced house and just as confidently walk away from an overpriced one, since half of overpaying is being too rushed or too unsure to negotiate properly.
A home inspection, typically $400 to $600, is where an overpriced house with hidden problems usually gets caught before it is too late, and financing and inspection conditions written into the offer are what let a buyer walk away without losing a deposit if something turns up.
