don't know about Miami, their big boom was more in the last cycle (ending 2008) with the brickell boom.
amazing that 8 of the 10 tallest buildings in NYC had been built in the last 10 years. the top 30 is similarly stacked with less than 10 year old structures.
In terms of urbanization though, Dallas / NYC / Houston have added the most multifamily in the US. Dallas-Fort Worth still has more than 40,000 units under construction.
Seattle, DC, Austin, maybe Nashville have also been in the mix.
