But complicated easements for MARTA and the nearby railroad companies, outdated real estate records and difficulties purchasing some parcels have held up an agreement.
A frustrated Reed had earlier in January set the end of that month as a deadline for WRS to make a deal.
Reed reversed course on Jan. 31, saying he would give the company more time because they were working hard to get a deal done.
A spokeswoman in Mayor Kasim Reed’s office on Friday said there was “no update yet” on talks to sell the property.
“Right now everybody is working as close to the deadline as possible,” Reed said at the recent groundbreaking of a southwest Atlanta park honoring pioneering black doctors in the city.
“I shouldn’t be unreasonable solely because I said the 31st,” he said.
The city is trying to sell Underground for about $34.5 million and Reed has said there are other interested buyers.
