As an update, finally, several of these units are now for sale. Some have final photographs while others have early/generic photos, ranging from $237k for an 866 sq ft 1 bd 1 bath to $585 for a 2,300 sq ft 2 bed 2 bath.

Those would have a $4,600-$6,000/month payment while the Central Park townhomes will range from $1,600/month up to $4,000/mo for the largest unit if you have almost no down payment. So at least there's some options for "regular" top-10% income earners!
My guess is actual sales will be closer to $500k max, especially right now with what seems to be a flood of expensive houses on the market in Midtown. Many of the pricier homes ($400k+) are staying on the market a bit longer. How many people can even be qualified for those kinds of prices right now that haven't already bought a home recently? With rates expected to rise, I'd expect the market to dry up even further as that $4,600/mo lower range for Urban 8 could go up to $5k/mo with just one more interest point.
