Confidence in the market for new multifamily housing declined year-over-year in the first quarter, according to the Multifamily Market Survey (MMS) released by the NAHB. The MMS produces two separate indices. The Multifamily Production Index (MPI) had a reading of 44, down three points year-over-year, while the Multifamily Occupancy Index (MOI) had a reading of 82, down one point year-over-year. …The MPI is a weighted average of four key market segments: three in the built-for-rent market (garden/low-rise, mid/high-rise and subsidized) and one in the built-for-sale (or condominium) market. The component measuring garden/low-rise dipped one point to 54, the component measuring mid/high-rise units fell eight points to 28, the component measuring subsidized units held even at 50 and the component measuring built-for-sale units posted a one-point decline to 38.
