Realtor.com has monthly and weekly data on the existing home market. Here is their weekly report released today from Chief Economist Danielle Hale: Weekly Housing Trends View — Data Week Ending Nov 19, 2022. Note: They have data on list prices, new listings and more, but this focus is on inventory. • Active inventory continued to grow, increasing 49% above one year ago. Inventory accelerated again, notching a sixth straight week of growth in the yearly trend roughly at or above 2%–in this case nearly double.
• New listings–a measure of sellers putting homes up for sale–were again down, dropping 17% from one year ago. This marks a twentieth straight week of year over year declines in homeowners listing their home for sale, a tangible reflection of the ongoing decline in seller confidence.Here is a graph of the year-over-year change in inventory according to realtor.com.
Note the rapid increase in the YoY change earlier this year, from down 30% at the beginning of the year, to up 29% YoY at the beginning of July.
