105 Lexington - Worth the Price?

I know 105 Lexington has been discussed on this site before, but just wanted to get opinions on the latest “deal”. Corcoran is offering 10% off the agreed-upon selling price if you close withing 45 days.

Assuming you can actually close in 45 days (given all the Nov/Dec holidays), what are people’s thoughts on the discounted price psf, given the neighborhood (which I’m not overly familiar with)? The $550k/$525k units are btwn 1100 and 1300 sq ft, so in the $450 psf neighborhood before the chop and roughly $405 psf after?

Also, would you rather live here or in “East Williamsburg” at the same price?
