"That's not true" is too strong a statement on your part.

The statistic you cite does not necessarily contradict what the parent comment is saying. "Up 29% since February 2020" is an absolute change since a specific point. The parent comment is saying prices have "come down" i.e. since their peak. It can still be up overall, so long as it's not up as high as it was at one point.

EDIT: To be clear, the parent comment might still be wrong, or might be right only within a biased sample (i.e. their own experience). I'm only making the point that the statistic you're referencing does not outright disprove what they're saying. Prices can be up since six years ago AND down since two years ago (random time periods chosen for illustration only).
