In the 2022 US housing report from the National Association of Realtors and Move.com, which operates Realtor.com for the NAR, the big news is more of the same. The market is now, by their count, 6.5 million new single-family homes short of population and household formation growth. For multifamily, that turns into good economic news.

It's impossible to look at multifamily independent of single-family homes because the two markets are intertwined with household formation. Between 2012 and 2022, there were 15.6 million household formations in the US, according to NAR, with nearly 2.1 million last year.

As formations happen, they need to live someplace, but there aren't enough traditional single-family homes. During those 10 years between 2012 and 2022, 9.03 million single-family homes were started, with 8.5 million completed. That would be a 7.1-million-unit gap. There were also 4.2 million multifamily unit starts and 3.4 million completions.
