NEW YORK CITY-Space at 780 Third Ave. is rapidly filling up with the completion of 12 lease transactions in the TIAA-CREF-owned building. The leases were completed by a team from JRT Realty Group, consisting of executive vice president Greg Smith, founder and president Jodi Pulice and associate Kate Pezzolla.

Smith tells GlobeSt.com that the rapidity of the transaction--12 leases in 12 days--signals the increase that has been seen in the Manhattan office market, with prime spaces drawing a premium.

“That was the fastest lease-up cycle for that many transactions,” Smith says. “We’ve been able to raise rents by $10 a square foot following all of these leases.” With these leases, which total 50,000 square feet, the building is currently 97% leased.
