Appliances like cars will be affected by the semiconductor shortages which are a result of both covid disruption in a long-leadtime industry and the devastating fires, first last October at the AKM fab and just a month ago, at Renesas in Japan.
While this was in Japan, 83% of the worlds CPUs and 70% of memory are manufactured in South Korea and Taiwan so just think for a minute about how little it will take to disrupt every industry that depends on them.
As for home buying plans, things are going to have to slow down if my area is any indication. The housing market has been on fire, houses that were on the market for months in the past are selling in a couple of days. It will slow down because there aren’t any houses to buy.
It will also slow down because those who sell their homes have to buy another somewhere else and when there isn't enough existing home inventory to enable movement of buyers and sellers the housing market comes to a halt. Additionally new home sales are dropping because of two factors: accelerating prices and the the lack of lumber coming across the border from Canada driving lumber prices through the roof, causing builders to put new home construction on hold until lumber prices come down.
As for housing, it looks to me like it's going to get a whole lot uglier before it gets any better.
