Cause Or Simply Correlation
Events and market conditions can cause quick changes in real estate trends, but there are almost always multiple factors affecting home prices. A change in interest rates can quickly change how many new homes developers want to build. Local governments can change zoning, affecting the types of housing built.
New homes almost always sell at a premium over older homes. A significant change in the number of new houses sold would affect the average sales price. The graphs above show that the median age changed little, while the average changed significantly. This implies that a relatively small number of younger, likely new homes were affecting the average age, but their numbers dropped dramatically in 2019.
