Photos on the listing show rooms inside the two-bed house in plush Camden Mews, stuffed to the ceilings with rubbish.
Others show cracked walls, holes in the ceiling, damp and cobwebs.
The outside of the run down house is completely overgrown and an abandoned car, covered in leaves, is also seen on the driveway.
But despite its modest appearance, the end-of-terrace property is being sold at auction next month with a guide price of £925,000.
Auction House London say the house’s location means that even the most “unattractive, unappealing properties” such as this hold “real promise”.
London writer Ian Visits shared a link for the property on his social media accounts, saying: “If you are feeling brave (and maybe own a hazmat suit), what’s left of the house under all this is having an open day for prospective buyers.”
The property – 75 Camden Mews, in NW1 – is a freehold corner plot in one of London’s most desirable postcodes.
Despite its current condition, Auction House London say it has already drawn interest from developers and investors who recognise its potential.
According to property website Rightmove, nearby terraced properties sell for an average price of £1,273,670, with semi-detached properties selling for an average of £1,525,000 and flats fetching £1,280,000.
Andrew Binstock, auctioneer at Auction House London, said the property – which has been in one family’s ownership for the past 35 years – offers a ‘golden opportunity’ for redevelopment.
“Yes, the images are extreme,” he admitted. “But this is Camden NW1.
“In this location, even the most unattractive properties hold real promise.
“It’s a freehold corner site and, for the right buyer, this is a golden opportunity to redevelop and create something truly special.
“We’ve sold some of the most unappealing properties in the capital. It’s often the ones that need the most work that deliver the biggest return.
“Auction House London takes pride in its transparent marketing approach; showing properties as they are, even when the condition is less than ideal.
“At auction, we don’t stage or sugar-coat. We trust buyers to look beyond the surface and recognise the potential.”
The house will be auctioned off next month, in Auction House London’s last sale of the year. Visit https://auctionhouselondon.co.uk/lot/75-camden-mews-camden-london-nw1-9by-318590 for more information.
