It was a formality so the city could act like they were actually trying to find real bidders. Too typical, and sad.
Even if that statement is 100% true (I feel it's in the high 90's myself), does that change the fact that there is generally ZERO interest on that property from other developers?
Short of selling out with a complete marketing campaign from the city nation-wide to garner interest prior to setting out a 'legitimate' RFP, I don't believe it would have mattered if there was a 30 day window or a 30 year window. The property has been sitting vacant for 2 decades with a handful of pie-in-the-sky development proposals that were relying on a housing market that this nation has never seen before.
Khan's interest in the property is based on a more realistic and sustainable idea - enhancing his other major investment in the city.
