If Zillow says something, its probably the opposite.
The chief economist at Zillow believes that the market is "out of balance," by which they mean it is overpriced. This is generally out of alignment with most real estate opinions. The majority of opinions at the moment see the historic lack of supply, short marketing times and low interest rates as a sign for continued price growth in 2022. There are certainly pockets of the country (and the greater Richmond Metro area) that are in a bubble (Deep Run HS area is a prime candidate). However, this circus may still have another year of strong growth in it.
