This imposing Italian Renaissance Revival mansion in Virginia was built in 1912 for business leader and philanthropist Major James H. Dooley at a cost of $2 million (£1.6m), a hefty $51 million (£40m) in today's money. No expense was spared on the ultra-luxurious property, which took 300 artisans eight years to finish.

A romantic escape for Major Dooley and his beloved wife Sarah, Swannanoa was kitted out with furnishings worthy of a billionaire, including exquisite Carrara marble flooring and wall panels, along with gold plumbing fixtures. The home's wow-factor feature is a stunning 4,000-piece Tiffany stained glass window featuring a depiction of Mrs Dooley that cost the equivalent of $64,000 (£51k) when adjusted for inflation. 

The Dooleys summered at the property until Major Dooley's death in 1924. Mrs Dooley died in 1926 and Swannanoa passed to her late husband's two sisters, who didn't waste any time getting rid of it. The mansion was sold for the knockdown price of $300,000 (£238k) and converted into a country club, which opened in 1929 but closed in 1932 on account of the Great Depression.

The mansion was left empty for years. During World War II, the US Navy floated plans to purchase the property but was put off by the cost. Swannanoa finally found a buyer in 1944 when local businessman A. T. Dulaney acquired the dilapidated house for $60,100 (£76k). He leased it to polymath Walter Russell and his sculptor wife Lao, who established a New Age university on the estate.

Russell died in 1963 and his wife continued to lease the property until her death in 1988, when it was repurposed as the Russell Museum. Owners the Delaney family shut the museum in 1998 and partly renovated the property, but the vacant Gilded Age mansion, which they describe as a 'money pit', still requires extensive work, though it does manage to function as a venue for weddings and other events.

The Queen pulled out all the stops in 1986 when she gifted the Duke and Duchess of York a 665-acre parcel of land on the Sunninghill Park Estate in Berkshire following their wedding that same year. A swish 12-bedroom mansion was commissioned, complete with grand reception rooms, stables and a swimming pool. Construction work began on the flashy royal residence in 1987.

The Duke, Prince Andrew, and Sarah Ferguson's marriage broke down not long after they moved in and the couple divorced in 1996. Yet the duo continued to live under the same roof with their two daughters. Following the Queen Mother's death in 2002, the Duke decamped to the Royal Lodge in Windsor, her former residence, and Sunninghill Park was put on the market. The Duchess and their daughters followed in 2006, leaving the property vacant.

The Duke, who had remortgaged Sunninghill Park to cover the cost of renovating the Royal Lodge, lucked out in 2007 when he sold it to Kazakhstani investor Kenes Rakishev for $19 million (£15m), $3.8 million (£3m) over the asking price. The ultimate owner was later revealed to be billionaire oligarch Timur Kulibayev.

The property was effectively abandoned and left to rot. By 2009, Sunninghill Park was in a sorry state with windows smashed, doors hanging off their hinges and paintwork cracked. The grounds were overgrown with weeds growing through the paving. Local residents were up in arms and the county council even threatened to seize the house and turn it into a homeless shelter.

The mansion deteriorated further. In December 2013, planning permission was granted to replace the rundown property with a bigger 14-bedroom home, but demolition work didn't begin until 2015. At long last, the eyesore was reduced to rubble in 2016, and the new house is finally nearing completion, much to the relief of the neighbours and local authority.

A monument to shameless corruption, the Mezhyhirya Residence in the Ukraine was the official summer house or dacha for the Soviet leadership, and passed to the Ukrainian government following the dissolution of the USSR in 1991. Viktor Yanukovych moved into the property in 2002 shortly after his election as prime minister and went on to spend millions of dollars of ill-gotten cash on it.

Yanukovych was evicted from the residence following the Orange Revolution in 2005 but returned as prime minister in 2006. The politician had the property privatised the following year. The estate's Soviet era buildings were demolished and work began on a five-storey stone and timber palace designed by Finnish firm Honka, which is thought to have cost at least $10 million (£8m).

The no holds barred spending extended to the opulent bathrooms, which were fitted with the most expensive gold fixtures money could buy. Yanukovych installed an underground shooting range and dropped $3 million (£2.4m) on a golf course. A pricey bowling alley and tennis courts were also constructed.

Yanukovych also had a garage complex built to house his vast collection of classic cars. Karma eventually caught up with the president, who was ousted by the Ukrainian Revolution in 2014 and fled the country. Wanted for high treason, Yanukovych is currently hiding out in Russia. His abandoned palace, a testament to the man's extravagance, is now a museum. 

There was a swanky red-walled nightclub in the complex, which had a bar stocked with the best vintage champagnes, fine wines and spirits.  The Gbadolite complex also had several huge swimming pools, a five-star hotel for visiting dignitaries and a number of plush guesthouses to boot.

Mobutu was deposed in May 1997, having embezzled up to $15 billion (£12bn). The ex-president fled to Morocco, where he died later that year. Gbadolite was looted and all its valuables were removed or destroyed. The jungle has since reclaimed the complex, which lies ruined and abandoned. 

The sprawling country house was built for copper tycoon Hugh Robert Hughes, who became known as HRH due to his suitably regal lifestyle. The mansion passed through several families and was last used as a private home in 1929, when it was sold to the highest bidder and converted into a boy's school.

Kinmel Hall was added to the Victorian Society's Top 10 Most Endangered Buildings list in 2015 due to its worsening state. The current owner, who resides in the Cayman Islands, has pretty much left the grand mansion to wrack and ruin, and the restoration bill is now likely to cost in the region of $25 million (£20m). 

Jackson renamed the property Neverland after the magical island in Peter Pan, and set about creating his very own amusement park. Jackson had two railways and a station (pictured) built to complement the Tudor-style six-bedroom mansion that came with the property and installed a petting zoo and numerous amusement rides. 

Neverland had everything from a Ferris wheel and pirate ship ride to a carousel and bumper cars. While Jackson was still universally adored, if thought to be a little odd, he hosted many events at the ranch, including the 1991 wedding of his close friends Elizabeth Taylor and Larry Fortensky.

In 2003, Jackson was charged with child abuse and Neverland Ranch was turned upside down by police searching for evidence, but the singer was eventually acquitted on all charges. Jackson complained of feeling “violated” following the search and vowed never to live at the ranch again.

In 2006, Neverland shut down and most of the staff were sent packing. Up to his eyeballs in debt by this point, Jackson struggled to hold onto the property. Investment firm Colony Capital bought a majority stake in 2008 for $22.5 million (£17.8m), and the ranch's amusement rides were removed. After Jackson's death in 2009, the ranch fell into disrepair and the property was put up for sale in 2015 with an asking price of $100 million (£79m). 

Despite lowering the price to $67 million (£53m), the house remained unsold and in February 2020 it was removed from the market. In 2019, the harrowing documentary Leaving Neverland told the stories of two men, Wade Robson and James Safechuck, who allege they were sexually abused as children by the singer. After such horrific accounts, it's unlikely that anyone will want to call this particular property home again. 

White invested in the studio but the house lay neglected for years. Trevor Bishenden aka TrevBish Photography captured the dilapidated interiors last year when the manor appeared to be completely abandoned with rising damp and wallpaper peeling off the walls. Fortunately, Hook End has since been given a new lease of life and is in the process of being brought back from the brink.

This venerable historic plantation house in Leesburg, Virginia sits on 212 acres and dates back to 1700. The mansion was rebuilt in 1902 in a Colonial Revival style by its then owner Elijah Brokenborough White, who hired the most prestigious artisans he could find to deck out the rooms, which are notable for their fine panelling.

The 20-room house also featured one of America's first intercom systems. White bred champion racehorses at the estate and was wealthy enough to maintain the elegant neo-classical property to a T. During its heyday in the 1920s, the mansion hosted grand balls and dinner parties that were attended by local politicians and other VIPs.

Maaten effectively abandoned the property in the early 2000s. Left to the elements, Selma Mansion began to fall apart. The crumbling house was slowly reclaimed by nature and the interiors were targeted by vandals. Period features were smashed up or stolen, and parts of the roof caved in, as these photos from that time show.

In 2016, local resident Sharon Virts spotted the house on the list and vowed to buy and restore it. Delighting conservationists, Virts and her husband Scott Miller persuaded Maaten to sell and succeeded in acquiring the property for $1.2 million (£953k). Rescued from ruin, Selma Mansion is currently being restored to its former glory.
