I know a guy that is, maybe now was, putting together a REIT to invest in dozens of LIC condos. I bet plans will change. However, LIC real estate is blowing up no matter what - close to midtown and very under-developed, even with all the new buildings going up.
NYC eclipsing Boston as a tech hub? In consumer and retail digital, NYC is way ahead. People here look at Boston tech as dusty, old school enterprise scale stuff, like EMC, etc.
However, I think Boston still has a big edge on NYC with tech, especially once you add in biotech, etc.
The other thing to remember is that NYC is over 10X the size of Boston and NYC metro is 3-4X the size of Boston. There is so much other stuff here, that yes, it would have been a draw, but remember the scale and diversity of NYC market. Citi employs close to ~25K people and JP Morgan employs ~38K people in NYC.
