Selling agent Cameron Macneil of Oliver Road Estate Agents said the sale of 64 Harbour Drive went unconditional on Friday for an amount "in the vicinity" of the asking price.
The buyer was in a band and planned to keep using the ground floor as Rudd had, as a recording studio-cum-man cave.
Asked if the buyer was a fan of the Australian rock band, Macneil said the buyer was "of the generation" to be an AC/DC fan, but had bought the home as a retirement house for him and his wife.
He would not comment on Rudd's next move or whether he had bought a new property.
Rudd, 65, has said he plans to downsize from the 586sqm home but stay local to Tauranga, where he has lived since the 1980s as has assets including a restaurant, Phil's Place, boat and a hangar at Tauranga Airport.
This was the second time Rudd had tried to sell the home he had lived for the past nine years.
It was the place where he served his eight-month home detention sentence in 2015 after pleading guilty to charges of threatening to kill an employee, and relating to methamphetamine and cannabis found in his home during a police raid in 2014.
The house was well known in Tauranga, and Macneil said Rudd would be looking for something more low-key, possible in Mount Maunganui or Pāpāmoa.
The listing attracted attention from all over the world.
OneRoof editor Owen Vaughan said the listing was OneRoof's most viewed property last year and it was believed to have set a New Zealand record, exceeding 200,000 views across three top real estate sites.
Macneil said all the buyers who walked through the house had been genuinely interested, rather than just nosey.
There had also been some interest from neighbours.
"It was quite funny, one buyer walked along Phil's wall of memorabilia and said 'is this guy a bit of an AC/DC fan or something'," Macneil said.
Rudd was dismissed from AC/DC in 2014 following his legal troubles, but has recently been connected to the band again, and photographed with members.
