September 2022 Case-Shiller Results & Forecast: Holding Tight

September brought about high interest rates and slowing sales, which continued to slow home price growth annually. On a monthly level, home prices continued to drop. While buyers are stepping aside waiting for more affordable prices and rates – causing the slowdown on price growth – would-be sellers are sticking their ground and holding tight to the inventory they currently own.

September brought about high interest rates and slowing sales, which continued to slow home price growth annually. On a monthly level, home prices continued to drop. While buyers are stepping aside waiting for more affordable prices and rates – causing the slowdown on price growth – would-be sellers are sticking their ground and holding tight to the inventory they currently own. As a result, prices might not continue to plunge down as much as some projections anticipate— as the available inventory of homes on the market is constrained.
