Mr. Fogelberg, who died in December at age 56 after a prolonged bout with prostate cancer, first listed the 610-acre ranch in 2005 for $17.5 million. Its most recent asking price was $15 million. The planned purchase price couldn't be learned. Mr. Fogelberg, who rose to fame during the 1970s, custom-built the estate, in Pagosa Springs, Colo., near the Wolf Creek Ski area.

Dubbed "Mountain Bird Ranch," it comprises a four-bedroom main house with a greenhouse, a gym, and a professional recording studio; a caretaker's house; and a studio apartment above a three-car garage. The property's terrain includes many hills, creeks, lakes and ponds. There's a 12-stall stable, riding arenas and other outbuildings.

The buyer could still back out depending on a survey of the property and other due diligence, says listing agent Joshua Saslove, of Joshua & Co., an affiliate of Christie's Great Estates. He declined to provide further details.

Known for his sensitive, soft-rock ballads, Mr. Fogelberg rose to fame with hits including "Leader of the Band" and "Same Old Lang Syne." His widow, Jean, also owns a home in Maine.

Former James Jones Home to Go on Sale

A developer has renovated the former Hamptons home of "From Here to Eternity" author James Jones and plans to put it up for sale for $12 million to $14 million.

In 1975, Mr. Jones and his wife, Gloria, moved to the house in Sagaponack, N.Y., and hosted writers such as Arthur Miller and Kurt Vonnegut. Mr. Jones died in 1977 at age 56, but his wife lived in the house until she died in 2006 at age 78.

Their children then sold the 1.5-acre property for roughly $4 million to developer Peter Sabbeth, who restored the original 3,500-square-foot wood house and expanded it by 4,000 square feet. Specializing in ecologically focused design, Mr. Sabbeth added solar panels and a geothermal heating system. There are five bedrooms, nine bathrooms, a two-car garage and a pool. A planned basement will include a wine cellar, gym, playroom and steam bath.

Construction is in the final stages, Mr. Sabbeth says. Next week, designers will begin decorating the home as part of the annual Hamptons Cottages and Gardens Idea house, scheduled to open July 26. Rylan Jacka, of Sotheby's International Realty, has the listing.

Sale of Former Cliff Robertson Estate

The La Jolla, Calif., beachfront estate owned for four decades by actor Cliff Robertson has sold for $16.5 million, records show. That's down about 40% from its original $28 million asking price.

Next door, former Massachusetts Gov. Mitt Romney recently paid $12 million for an oceanfront house. The purchasers of the Robertson property are John and Victoria Miller, former national-finance heads of Mr. Romney's presidential campaign. Mr. Miller is the chief executive of National Beef.

The sellers of the Robertson house, real-estate developer Ronald Baldwin, and his wife, Amie, purchased the 1922 Spanish colonial in 2005 for $14.5 million from the 82-year-old actor, who won a best-actor Academy Award for "Charly." The 1.4-acre property includes a main house and guest house with eight bedrooms in all.

Agents Taylor Rork and Sue Nystrom Walsh, of Willis Allen Real Estate, had the listing.
