This deceased estate in Papatoetoe, Auckland, New Zealand is such a health and safety risk, open home viewers had to wear closed-in shoes and promise not to touch anything - in case bits of the house fell on them.
Listing agent Denise Wong of Ray White Manukau says it's "the ultimate do-up".
"It's the worst house I have ever seen in my entire life," she said.
"The outdoors has pretty much overtaken the indoors. It's not fully functional. The electricity is not working, nor the plumbing, and it needs new Gib and windows."
But the decrepit state of the 1980s "as is, where is" house didn't stop the auction attracting 30 registered bidders, almost all of whom wanted to renovate.
"They all came out of the woodwork for it, and the auction went off with a bang," Wong said.
Wong says more than half of the bidders placed bids - there were 73 bids in eight minutes, and the house sold under the hammer for NZ$466,000 ($427,674).
Its RV is NZ$720,000 ($660,783). The price fetched was almost three times the amount that had been offered before the house went to auction.
"They were all overbidding one another, and they all came in person; there was just one telephone bidder. I guess they could see added value and potential in the property," Wong said.
Wong says 28 of the 30 bidders had plans to renovate, while the other two talked about relocating a replacement house to the site.
"They were all seasoned renovators or DIY homeowners who worked in the building industry," Wong said.
"You needed the know-how for this one. It wasn't just a cosmetic flipper. I had to have open homes on four weekdays for a couple of weeks because that's when everyone wanted to come through with their builders. They estimated it might cost around NZ$200,000 ($183,551) to do up."
"Buyers needed to have cash for this one, because banks would not have loaned on the property due to its condition," Wong said.
Wong says the property was bought by a renovation and building company who will restore the house: "It will become a lovely home for someone."
