some more than others. There is a glut of supply that finally came into the market starting last year and continuing now. The move in specials, etc are designed to keep the monthly rents (on paper) as close to what they projected when they funded the project as possible, since valuations in the multi family sector are generally calculated as multiples of rent.
My personal opinion is that you’ll see more people in that sector move “up” into A housing like new apartment complexes that they can suddenly afford, with lots of amenities, and that ultimately the losers will be the older multifamily stuff.
