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 = 5.0 months of supply — inside the 4–6 month balanced range. In the basin, that is the water level against the shaded balanced band.

The net reading: about 34 more homes came on than sold each month, so inventory is growing. The basin is filling.
