New construction in San Diego seems to be very weighted toward luxury 2 bedrooms for $2400+.
That could slow rent growth just in that submarket. But overall construction is simply the lowest in modern San Diego records while the economy and population keep growing.
Even in that submarket, such places are popular with people moving here, students, retirees, and asian investment buyers.
If you think there is a lot of construction downtown now you don’t remember 2004-2008.
