$700,000 to $900,000 is the sweet spot for Manhattan. Might seem like a lot but better than 2-5 million, with a 30,000/month mortgage. Some 1 bedrooms can go for that on Park Ave. But thats cheap for the area purchasing wise.
I think in terms of selling, if developments can cater to the 500k-1 million/unit range, its quite desirable.
99 Hudson in Jersey city is having great success.

Check out the unit on floor 11. Again, might seem like a lot, but a would be 3x as pricier in Manhattan if not more.
Its amazing what a mile or two can mean in NYC or its proxies. A unit on the 64th floor at 1.930 million is a bargain compared to the 5th floor shack on the UWS or SoHo going for 5-10 million.

Honestly, I'd rather have a unit in Jersey City or Fort Lee overlooking the city. Much better bang for the buck.
