Confidence in the market for new multifamily housing increased in the third quarter, according to results from the Multifamily Market Survey (MMS) released by the National Association of Home Builders (NAHB). The MMS produces two separate indices. The Multifamily Production Index (MPI) rose 11 points to 48 compared to the previous quarter. Meanwhile, the Multifamily Vacancy Index (MVI) decreased 18 points to 44, with smaller numbers indicating fewer vacancies.

The MPI measures builder and developer sentiment about current conditions in the apartment and condo market on a scale of 0 to 100. The index and all of its components are scaled so that a number below 50 indicates that more respondents report conditions are getting worse than report conditions are improving.

The MPI is a weighted average of three key elements of the multifamily housing market: construction of low-rent units-apartments that are supported by low-income tax credits or other government subsidy programs; market-rate rental units-apartments that are built to be rented at the price the market will hold; and for-sale units-condominiums. All three components posted increases in the third quarter: the component measuring low-rent units rose four points to 46, the component measuring market rate rental units jumped 19 points to 53 and the component measuring for-sale units posted an 11-point gain to 46.

The MVI measures the multifamily housing industry's perception of vacancies in existing apartments. It is a weighted average of current occupancy indexes for class A, B, and C multifamily units, and can vary from 0 to 100, where a number under 50 indicates more property managers believe vacancies are decreasing rather than increasing. With a reading of 44, the MVI improved from previous quarter's index high of 62.  

"The third quarter survey results and NAHB's forecast suggest a rising share of multifamily construction in less dense areas of the nation in need of rental housing," said NAHB Chief Economist Robert Dietz. "However, material availability is a near-term concern, with the potential for rising regulatory risk in 2021."

Historically, the MPI and MVI have performed well as leading indicators of U.S. Census figures for multifamily starts and vacancy rates, providing information on likely movement in the Census figures one to three quarters in advance.
