I wonder what the prices will be in 98 14th? If they're higher than Aqua or 1010 then this is truly uncharted territory and there's a good reason to be skeptical. Calling condo demand "astronomical" is optimistic. It's a healthy market, but it's still easy to find two bedroom units in highrises for $300k. This might be a good test of how much of a luxury market Midtown really has. Sovereign has proven
Atlanta can bear it, and 98 14th will obviously be the tallest in the city, so that's something.
Speaking of skeptical

This is only a hunch, but I don't expect to see any big spec office projects for awhile. The BOA tower is indeed pretty empty, and I'm still not even convinced Tech's HPC will happen. All the big office projects have been in the suburbs, especially Cumberland where three or four are in progress. For Midtown, this cycle is clearly focused on residential.
