"The upright will dwell in the land" (2:21). Is that a promise that good people always keep their homes?

The chapter gives it as the reason for its last call: "Therefore walk in the way of good men, and keep the paths of the righteous" (2:20). "For the upright will dwell in the land. The perfect will remain in it" (2:21). "But the wicked will be cut off from the land. The treacherous will be rooted out of it" (2:22). It doesn't say when or how. A psalm has words like them: "For evildoers shall be cut off, but those who wait for the LORD shall inherit the land" (Psalm 37:9), and "The righteous shall inherit the land, and live in it forever" (Psalm 37:29). In Hebrew, the psalm's cut off, land and live are the words of Proverbs 2:21-22's cut off, land and dwell. And rooted out (Proverbs 2:22) is the verb of Moses' warning to Israel, "You will be plucked from the land that you are going in to possess" (Deuteronomy 28:63) (tap rooted out). These notes quote 2:21-22 as they stand, without making them a guarantee the text doesn't state or explaining them away.
