Picture the Listings Flow Ladder as a basin: new listings pour in from the faucet, the homes for sale are the water, and closed sales run out the drain.

The ladder: homes for sale ÷ monthly sales = 2.7 months of supply — below the 4–6 month range Lotvox treats as balanced. In the basin, that is the water level against the shaded balanced band.

The net reading: about 22 more homes came on than sold each month, so inventory is growing. The basin is filling.
