• Wall Street billionaire Stanley Druckenmiller has sold his Greenwich, Connecticut home. 
• It sold for $25 million after listing for $31.5 million.
• Druckenmiller was formerly an exec with Soros Fund Management.

Billionaire trader Stanley Druckenmiller, formerly a top investment strategist to George Soros, has sold his palatial Greenwich, Connecticut, estate for $25 million, according to the Real Deal.

That price is merely $2 million above the price he paid for it in 2004. It's just the third Greenwich sale above $20 million this year, listing agent Leslie McElwreath of Sotheby's International Realty told the magazine.

The estate has 12,238 square feet of living space and eight bedrooms in total. It sits on nearly 20 acres and is technically three lots combined into one.

Druckenmiller and his wife sold the home because they don't get enough use out of it, McElwreath said.

Druckenmiller is the former president of Duquesne Capital Management, which he founded before joining Soros Fund Management.

The estate, known as Sabine Farm, was built by publisher H.J. Fisher in 1910.

After Druckenmiller and his wife bought the estate in 2004, they renovated the mansion.

The home has 12,238 square feet of living space.

• Nothnagle Cabin is said to be the oldest home in America.
• Built in 1638, the house is currently owned by Harry and Doris Rink, who maintain the home and give free tours of the space.
• The log cabin was first listed in June 2017, and is still on the market for $2.9 million.

America's oldest home is for sale.

The log cabin, which dates back to 1638, has lasted this long with the help of its current owners, Harry and Doris Rink — who have taken the property under their wing, and have been living in an attached house since 1968.

History doesn't come cheap — with a $2.9 million price tag, the home includes all the artifacts inside, as well as the Rinks themselves, who want to remain on the property and continue to give tours of this historic site.

According to Harry, people lived inside the cabin until 1918, and the attached home that the couple resides in was built in the early 1700s. "We have the deed to the property dating back to 1791," Harry told The New York Times in an interview.

Restoration projects completed by the Rinks include reinforcing the walls with clay, and removing plaster that was on the interior walls. The property is 1,800 square feet, and has been on the market since June of 2017.

Built by Finnish settlers, the Nothnagle Log House was completed in 1643.

Today, the land that the cabin was built on is Gibbstown, New Jersey.

Its sellers, Harry and Doris Rink, have owned the property since 1968. Prior to that, Harry's aunt and uncle owned the property.

• An over-the-top property in the Bel Air neighborhood of Los Angeles was relisted for $188 million in April.
• It was originally listed for $250 million in January 2017.
• Luxury developer Bruce Makowsky, who calls himself the "spec king," developed the property.

In January 2017, a new home built on speculation in the Bel Air neighborhood of Los Angeles appeared on the market, asking an earth-shattering $250 million. According to its website, that made it the most expensive home ever listed in the United States.

Fast forward to April 2018, and that home has returned to the market with a reduced price. It's now listed by Hilton & Hyland for $188 million. It no longer boasts the title of most expensive on the market, but with a price that high, it is certainly up there.

And it really is unlike any other home on the market. The mansion is built in a contemporary style, with stark geometry and huge plate-glass windows.

The home also comes outfitted with furniture, but it's not your standard Restoration Hardware package. It seems it was built with a very specific person in mind: a person who likes decommissioned decorative helicopters, gigantic Leica camera sculptures, velvet-roped lounge areas, and plush decorations that were purchased from Hermès.

As for the living spaces, there are two master suites, 10 "oversized VIP" suites for guests, 21 bathrooms, three separate and fully equipped kitchens, and no fewer than five bars.

It was built by the luxury developer Bruce Makowsky, whom the release refers to as the "spec king." He was also the mastermind behind the $70 million Beverly Hills house sold to Minecraft founder Markus "Notch" Persson in 2014.

The sheer footprint of the mansion, spread across 38,000 square feet, is a sight to behold. The exterior decks alone are 17,000 square feet. Downstairs is a car park filled with over $30 million worth of collectible automobiles — all of which are included in the purchase.

Situated on a hill, the house has a 270-degree view overlooking the LA area — one of its defining features.

Inside is where things get a little bit funky. The decor is not your typical boilerplate luxe style.

A hunter's paradise is having a hard time finding a buyer.

It's called the Granot Loma, and according to the listing, it may be the largest log-cabin lodge in America.

With a private marina and 5,000 acres of surrounding woodlands, the 26,000-square-foot house was listed for a staggering $40 million in 2015 making it the most expensive house in Michigan.

Bob Sullivan of Northern Michigan Land Brokers formerly had the listing. It is now for sale by its owner for $20 million — a discount of more about 50%.

Called Granot Loma, this gigantic log cabin sits on the shores of Lake Superior, north of Marquette, Michigan.

It was built and named in 1923 by its original owner, financier Louis G. Kaufman.

Kaufman played a pivotal role in the founding of General Motors, where he was on the board for 20 years.

Ivanka Trump is now a full-time resident of Washington, DC, and she no longer has any use for her Manhattan pied-à-terre.

Though it was originally listed for sale for $4.1 million, the two-bedroom apartment is also now available on the rental market. First listed for $15,000 a month, it was knocked down to $13,000 a month in February. It's now available for rent for $10,450 a month.

Trump reportedly bought the apartment for $1 million in 2004, according to Luxury Listings. It sits underneath the four-bedroom penthouse the family also owns in the same Park Avenue building.

It is listed, appropriately, with Trump International Realty.

Playboy founder Hugh Hefner has died at 91, Playboy Enterprises confirmed in a press release Wednesday night.

For the last 40 years, the entertainment icon made his home in the infamous Playboy Mansion, the site of many a crazy party. 

Hefner never technically owned the Los Angeles estate. He leased it from Playboy Enterprises and paid $100 a year in rent.

In August 2016, the nearly 20,000-square-foot house sold for $100 million to Daren Metropoulos, a principal of the private-equity firm Metropoulos & Co. and a former co-CEO of Pabst Brewing Company.

As part of the terms of the sale, Hefner was allowed to continue living there for $1 million per year. Now that he has died, the mansion and its five-acre grounds will officially have no further ties to Playboy Enterprises.

Let's take a look around Hefner's longtime home:

The 20,000-square-foot house is on the edge of the Los Angeles Country Club in the Holmby Hills neighborhood, right between Beverly Hills and Westwood.

The five-acre property includes the main mansion and a four-bedroom guesthouse.

For decades, invitations to Playboy Mansion parties were highly coveted, and stories of the wild nights here are Hollywood legend.

Netflix Chief Content Officer Ted Sarandos, who has acquired new programming for the company since 2000 and who received $18.9 million in compensation in 2016, recently purchased a Malibu property for $20 million with his wife, Nicole Avant, Variety reported.

The oceanfront, three-story home is a modern-day Italian palazzo with beach access and a guest house.

Sarandos purchased the property from Los Angeles-based financier J. Blair Frank, who had rented the property to Janet Jackson in 2009. Sarandos and Avant also own another home in Malibu.

The Obamas may be moving uptown.

Page Six reported Monday that the Obama family had been considering buying a $10 million condo on Manhattan's Upper East Side.

The Obamas have reportedly been seen entering and exiting a building on Gracie Square. Property records show that a nine-room duplex at that building went into contract on September 26, which sparked the purchase speculation.

The building itself is 15 floors and was built in 1930. The listing calls it "one of the foremost elegant and coveted buildings in New York." 

It has an indoor squash or basketball court for residents as well as lobby staff and a "live-in resident manager." One of the most important features: a private drive-through for easy drop-off — a feature that could be essential for someone under Secret Service protection.

A spokesperson for former President Obama did not immediately return Business Insider's request for comment.

Earlier this year, the Obama family reportedly purchased the Washington, DC mansion they had been renting since leaving the White House. The purchase price was $8.1 million. They also own a home in Hyde Park in Chicago and were rumored to be looking at vacation homes in Martha's Vineyard, though a spokesperson for the family has said that those rumors were not true.

Take a look around the luxurious duplex apartment, which was listed by Brown Harris Stevens until it went into contract last week.

Harvey Spevak, former CEO and current executive chairman and managing partner at the boutique fitness chain Equinox, has been trying to sell his condo in New York's Park Imperial tower condo since 2011.

First listed unsuccessfully for $11.995 million that year, the home later went off the market for some time. Then, in Feburary of this year, it returned for $9.5 million before being lowered further to $7.5 million in September, Curbed reported.

The duplex — two properties that Spevak and his wife, Rhonda, purchased separately for $2.5 million and $2.95 million — were combined to make a single, 2,954-square-foot duplex.

The condo was once two separate units, the first of which the Spevaks purchased in 2005. They purchased the second in 2008. The couple combined the two spaces into one, 2,954-square-foot duplex with the help of architect Ismael Leyva.

Fashion designer Elie Tahari's Hamptons home has just gone on the market for $45 million. 

Tahari originally purchased the home for $12.1 million in 2005. The designer said in a statement to the Wall Street Journal that he's selling it because his focus is currently on his business. 

"I haven't been there for the last two summers," he said in the statement.

During one of those two summers, the Sagaponack home was rented to a hedge fund manager for nearly $800,000 for the months of July and August, the property's listing agents, Keith Green and Ann Ciardullo from Sotheby's International Realty, told the Wall Street Journal.

The home is 5,200-square-feet and has four flours.

For the first time in three decades, Cross Mountain Ranch has hit the market. With an asking price of $100 million, the ranch is a whopping 224,050 acres — larger than New York City.

Located in northwest Colorado, Cross Mountain is one of the biggest ranches in the US. Its previous owner was the late real estate tycoon Ronald Boeddeker, who developed luxury properties like Lake Las Vegas. 

Ahead, take a look at the massive property, which includes multiple homes, recreational activities, and livestock operations. It's currently on the market with Mirr Ranch Group.

The Cross Mountain Ranch property is so large, it contains two different ecosystems. The land consists of green forest in the Williams Fork River valley, and high desert country that runs along the Yampa River.

There are numerous homes on the property, including this 11,000-square-foot log lodge. Inside are nine bedrooms and nine-and-a-half baths.

There are also barns, shops, and livestock-handling facilities, as well as manager and employee housing on the property.

The Pierre, a legendary hotel in New York, is home to one of the city's most dubious distinctions.

The entire 39th floor of the 41-story hotel overlooking Central Park is again being offered as a rental for $500,000 a month, making it the city's priciest rental listing once more.

As part of the Pierre Hotel Residences program, interested tenants can sign a lease for as little as 30 days, or for as long as they need. 

Renters have the option to make their monthly payments by credit card if they choose.

The six-bedroom residence was last offered in February 2017, though it's been on and off the market several times. It's now back for the same exact price.

The best part of living in this swanky hotel may be the many luxury services The Pierre offers. Residents are given complete access to the butler service, pet pampering, twice-daily maid service, and the hotel's chauffeur-driven Jaguar.

The listing is being handled by Andres Perea-Garzon of Corcoran.

This week, CNBC's "Secret Lives of the Super Rich" went inside what anchor Robert Frank called "the most amazing home we have ever shot."

The seven-floor home, located at the St. Moritz ski resort in Switzerland, was "designed to make a billionaire's jaw drop," listing agent Senada Adzem of Douglas Elliman Real Estate told "Secret Lives of the Super Rich." At $185 million, it's the most expensive home on the market in Switzerland at the moment and is reportedly owned by an unnamed billionaire.

With perks like a private ski lift to the slopes, a $1.3 million home theater, an underground lake, and rooms that surround you with 24-karat gold walls, this home is truly a playground for the wealthy.

For just the third time in nearly a century, the enormous Salutation Island has hit the market. For $125 million, you'd own the island's six homes and over 85 acres of land and water, according to Bloomberg.

The estate is located on the North Shore of Long Island and was first owned by J.P. Morgan's grandson, Junius Spencer Morgan III. Its most recent owner was socialite and real estate broker Margo Walker.

Below are highlights of the island and its amenities, which include a 27,000-square-foot mansion, 250-foot-long dock, horse stables, and an eight-car garage. The property is being sold by Daniel Gale Sotheby's International Realty. Let's take a look around.

The main residence is known as the "Manor House."

It was built by Junius Spencer Morgan III in 1919.

Anyone who saw the documentary or Broadway play would likely balk at living in the actual home that "Grey Gardens" inspired. After all, the home was in poor shape during the filming of the documentary, and it's even rumored to be haunted.

But eight months after being put onto the market, the home has finally found a buyer, the Washington Post reported. It was originally listed for just shy of $20 million in February, though that price was reduced to $17.995 million in April. 

The East Hampton, New York, mansion now looks nothing like it did in the 1975 documentary showcasing the lives of Jackie Kennedy Onassis' ex-socialite relatives. 

Journalist and author Sally Quinn purchased the mansion with her husband, the late Washington Post editor Ben Bradlee, for $220,000 in 1979. They completely rehabilitated it to the current splendor that it now shows, according to The New York Times.

Quinn would not diclose the name of the buyer or what he or she paid, though she told the Post that this individual "really understands the house." She added that she will be holding an estate sale of many of the home's furniture pieces, including things she found when she first bought the house.

The Corcoran Group had the listing.

• A Martha's Vineyard estate is now for sale for $17.75 million.
• It's been on the market for years and has seen several price cuts.
• It was used by the Obama family as a summer getaway in 2013.

This isn't just any ordinary picturesque Martha's Vineyard estate — it has a presidential pedigree.

President Obama and his family rented this sprawling, 7,000-square-foot mansion for an entire summer in 2013, according to The Wall Street Journal. But that seems not to have made the house any easier to sell.

Now it'll be just a little bit cheaper to live like the First Family all year round. The house listed in July 2015 for $22.5 million. Just three months later, the house already had a 15% price chop. 

Now, nearly two years later, the house is still for sale, at a discounted price of $17.75 million.

Sotheby's International Real Estate has the listing.

• Social media star Jake Paul has reportedly bought a new mansion in Calabasas, CA.
• It covers 15,000 square feet over 3.5 acres, and he paid $6.9 million for it.
• Paul had previously stirred up controversy by annoying his neighbors.

20-year-old social media star Jake Paul has a habit of annoying his neighbors, so anyone who lives near his new, $6.9 million mansion in Calabasas should be on high alert.

Before Paul reportedly bought it, the home had been listed for $7.395 million, according to the Los Angeles Times. 

Paul, who became famous by making short videos on the now-defunct social media platform Vine, has built a following of over 11 million subscribers on YouTube. He also acts on the Disney Channel show "Bizaardvark" and started a management company for social media personalities.

After he claimed that his neighbors tried to kill him in July, it makes sense that Paul would be looking for a new home. 

Here's what his new, 15,000-square-foot mansion looks like.

• Alan Wilzig is the inspiration for a character in "The Wolf of Wall Street."
• He's been trying to sell his Tribeca townhouse for years.
• The home recently had its price chopped by another $1 million.

Alan Wilzig, the real-life inspiration for a character in "The Wolf of Wall Street," is having a hard time getting rid of his New York City home.  

Wilzig's Tribeca mansion has been on the market since 2014, when it listed for $44 million. It was later offered for $24.885 million and is now up for sale again for $18.75 million, down from $19.75 million in its fourth price chop. 

Each time the townhouse gets relisted, its staging gets more and more tame. Many of its more eccentric features have disappeared and it's now more of a typical space in line with the surrounding area.

The 6,500-square-foot townhouse has a 2,200-square-foot roof deck, backyard, three bedrooms, and an attached multipurpose garage.

Wilzig inspired the character who introduced Leonardo DiCaprio's character to his future wife in a pool-party scene in the 2013 film.
