Copper Beech Farm, the 50-acre (debt-laden) Greenwich estate that roared onto the market in May with a record-setting $190M price tag, has since suffered the fate shared by so many of its nine-figure peers: it's been mercilessly slashed, now asking $140M. Owned by timber mogul John Rudey, the property is stocked with a 12-bedroom mansion, a whopping 4,000 feet of water frontage, and not one, but two offshore islands. [link]

In January, Texas business honcho Tom Hicks put his vast, Dallas, Texas, spread on the market for a staggering—nay, otherworldly—$135M, making it the priciest ask in the country at the time (no small feat, indeed). Despite once owning the Texas Rangers and being appraised by Forbes in 2009 to have a net worth of about $1B, Hicks has stumbled financially in the last few years, so it may be no real surprise that he's looking to unload a house that is, as the Real Estalker points out, 10 times the size of the average American home.

In September, NYC's most expensive single-family home, The Residence at Manhattan's River House building, was listed for a whopping $130M. What's on offer? Well, developers propose converting the apartment tower's private club into a home with 30 rooms, an indoor pool, a private entrance, and an earnest brokerbabble promise to be "one of the grandest urban residences in the world." As rumors foretold, it's New York's most expensive home, and—with 62,000 square feet over five levels and "enough room for about 10 typical Manhattan townhouses," as the Wall Street Journal put it succinctly—also the city's largest single-family home.

The 258-acre Bel Air Canyon, a vast parcel of undeveloped land in one of the country's priciest neighborhoods, came up for sale this summer for a whopping $125M. That makes it the most expensive publicly listed property in Los Angeles County. (Fleur de Lys, a 35,000-square-foot megamansion, had most recently been asking exactly that price tag, but it appears as though it is no longer officially on the market.) Anyway, located just north of, and across the 405 from, the Getty Center, this giant tract comprises 6 percent of the total land area of Bel Air. [link]

Despite the fact that Curbed NY dubbed One Beacon Court "a somewhat boring Midtown building beloved by business-world billionaires," hedge funder Steven Cohen was optimistic enough to ask $115M for an apartment that most recently sold for around $24M. Prior to listing, the apartment (the building's only duplex) got a Gwathmey Siegel reno that left Curbed NY feeling "a little cold, though Cohen's odd art collection (minus the head made of frozen blood, which is maybe a little much for a listing pic) enlivens things a bit."

In mid December, a 19th-century Manhattan townhouse hit the market for $114,077,000. Vincent Viola, the owner of the Florida Panthers, and his invitation designer wife, Teresa, bought the house for $20M in 2005 and have since festooned their 20,000 square feet to be anything but subtle. Take, for example, the 900-square-foot dining room, which got the Versailles treatment (far from a new design strategy), or floors made from old railroad ties. There's also a Venetian-onyx elevator, gold-leafed walls, a red velvet home theater, and every possible breed of marquetry and inlaid wood. [link]

In August, a 29,000-acre portion of the Y.O. Ranch, one of Texas' most storied cattle ranches, hit the market for $85M. The property includes a main lodge with 40-foot ceilings; "four original historic buildings"; extensive equestrian facilities; fenced pens for the keeping of exotic animals (like the giraffes pictured in the listing photos); and more than a few historic buildings that have been moved onto the property, like a century-old schoolhouse and an "1850s stagecoach stop."

This October, after a 2008 attempt to sell his penthouse compound atop the Plaza for $50M, fashion mogul Tommy Hilfiger re-listed the four-bedroom duplex—made of three combined apartments—for $80M. Five years and a 60 percent markup? Absolutely. In 2010, the place underwent a costly renovation (birds chirp a $20M overhaul price) and was subsequently profiled in Harper's Bazaar. [link]

This 15,520-square-foot SoCal sprawler designed by L.A. architectural poohbah Wallace Neff hit the market in the City of Angels for $75M. So what does Neff's 1973 Singleton House, which last listed in 2008 for an eye-watering $85M, have to offer? Oh, the usual: 10 bedrooms, a grand entryway perfect for prom photos, seven acres of "rolling" lawns, a private tennis court, and a motor court—all of which would be absolutely marvelous if the estate had anything by way of contemporary decor. Though, to be fair, it seems unlikely the orange velvet pillows or matching set of chinoiserie sofas and curtains are included the deal. [link]
