  1. Reports are being released earlier, which shrinks the early sample used for forecasts and raises the chance of bigger revisions; recent winter storms also delayed some closings and could make January sales look weaker than they really were.
  2. In the local markets that have reported, closed sales are down noticeably year‑over‑year (around -5.6% NSA), so seasonally‑adjusted national sales for January are more likely to be flat or slightly down instead of a strong gain.
  3. New listings are modestly down (~1.6% YoY) while active inventory is up (~5.8% YoY), so supply is higher than a year ago but still mixed compared with pre‑pandemic 2019 levels.
