The high-rent mark relates to properties with mostly direct units and space that’s prebuilt with high-end finishes or tower-floor locations. At the low end, the rents are affected not only by a preponderance of sublease space, but also by units that suffer from lower-profile location within the building or other undesirable features.

Finding the deals within these two extremes will remain a priority for hedge funds, Wasserberger tells GlobeSt.com. "Hedge funds tend to be opportunistic," says Wasserbeger, a JLL managing director who specializes in the sector. "They like quality, and the building’s cache and image is still important, but they’re looking for opportunities where other funds have vacated space in highly improved conditions. Also, pricing that’s fallen in the top-tier buildings may be more of a driver than it would have been 24 months ago."

Seeking out below-market opportunities within the prime hedge fund locations is not only a function of saving money. Taking on high-quality sublease space can also serve as a stopgap for funds that aren’t certain about their long-term space requirements. "Flexibility is important to the funds," Wasserberger says. "The future is unpredictable and their business needs may change quickly, so they want the ability to be nimble."

Notwithstanding the example of 375 Park in raising rents, Wasserberger says the general sense is that pricing on space will remain at its current level for some time. "So tenants are looking to tie in their requirements to the current market timing," she says. "It doesn’t work for everyone, but we find tenants coming to us for help in recasting a lease or doing what you call ‘blend and extend.’ Across the board, tenants are trying to figure out if they can use the market to their advantage and not miss out on what in hindsight will be the bottom of the market."
