It's not just lumber prices that are plaguing homebuilders.

The National Association of Home Builders reports that material shortages are now more widespread than at any time since it began tracking the issue in the 90's. Overall, more than 90% of builders report shortages of appliances, framing lumber and OSB. Exactly 90% said there was a shortage of plywood, while 87% said there was a shortage of windows and doors, according to a May 2021 survey for the NAHB/Wells Fargo Housing Market Index (HMI).

At least 70% of builders reported 12 items as being in short supply. Sixteen items were listed as in short supply by more than 60% of builders. Twenty-one items were checked as in short supply by more than 5%. All two dozen items tracked by the HMI were listed as in short supply by at least 43% of the builders. June 2020, when the HMI survey last covered the topic, less than 40% of builders reported a shortage of the listed products and materials.
