Unit and Building information:
1) new construction (sponsor unit)
2) a unit on the same floor with the same floorplan and square footage sold in June for a little less than 580 square foot (about 800k total)
3) a slightly larger unit with a very similar floorplan and on the same floor sold in July for about 590 a square foot (for about 860k total)

Thanks for your input.

Hi, not enough information for me, actually.

But OK, I'll play: no more than $580 a square foot as a start. Unless I'm in love with the place I would definitely bid less.

Are there different views, or a significantly different layout?
How many units are left? Is the one you want to bid on objectively better or worse than the 2 that sold?
Depending on the answers, I'd offer 500-550 psf
and see what concessions I can get (closing costs, parking, storage space, etc).

basically the same "views" as the comp units are all on the same floor (first floor). the building is about 70% sold.
