When I bought my house in a major US metro, any attempt to low-ball the seller simply meant your offer would go immediately in the trash in favor of one of the dozens of asking-plus bids, and continued attempts to do it was a surefire way to extend the unpleasantness of house hunting. And house prices in my city are up 20% since 2020, so I don't think the situation has become more amenable to low-ballers.

And that's all beside the point, because the information asymmetries in real estate markets are totally different from labor markets. This law reduces the information asymmetry to actually make labor markets more like real estate markets, in which all historical prices are public information and (in civilized jurisdictions, at least) all known relevant factors that might affect price are legally required to be disclosed.
