The leasing agents don't need optimism -- we're so under-supplied for housing I'd be shocked if the apartments don't lease up quite quickly.
It won't be cheap. Cheapest available 2 at 500 Ocean, which is across the street from Wonderland, is $3375 currently. Figure rent at these new apartments will be more than that. For that kind of coin, presumably you are talking about shacking up which is doable with the Blue Line.
