Simple Definition

The number of homes available for sale at a given time, often shown as active listings or "months of supply." Low inventory means few choices and more competition for buyers; rising inventory signals a loosening market.

Why It Matters

Inventory is the clearest gauge of whether the market is "frozen" or thawing. The lock-in effect crushed inventory for years; when it eased in 2026, active listings climbed back toward pre-pandemic levels — a key sign the freeze was lifting, even with affordability still strained.

Key Points

  • How many homes are listed for sale (active listings / months of supply).
  • Crushed by the lock-in effect; rising inventory signals a thaw.
  • Low inventory = fewer choices and more buyer competition.
