Jackson said he’d known Floyd since he was a teenager and said everyone called them twins.
Irving was asked about the gift Tuesday at a Nets media availability.
“I just want to keep continuing to fulfill our purpose in serving a lot of the underserved communities. Those don’t necessarily get the same attention from just others around,” he said. “So just trying to do my part with service, that’s all.”
In a statement, Jackson said Irving had been checking in on him to see what he could do.
“He wanted to help George’s family and I let him know that a house was what they needed at that time and he made it happen in a heartbeat,” Jackson said.
