A nearly 80-year-old estate on Old Santa Fe Trail, featuring a 10,000-square-foot, Spanish-Pueblo Revival-style main house, a guesthouse, a pool and equestrian facilities on 36 acres, sold for $7 million Wednesday — one of the top four home sales in Santa Fe in the 21st century.

It’s not clear who purchased the seven-bedroom, 12-bathroom property, which was listed for $7.9 million.

The seller was a limited liability corporation called Buddicea LLC, with addresses in Santa Fe and Nashville. Buddicea LLC was still listed on the Santa Fe County Assessor’s Office website as the property’s owner Friday.

Real estate agents Brad Furry and Christine McDonald, both with Santa Fe Properties, represented the buyer and seller, respectively. Neither returned calls to comment on the sale.

According to a report in The New Mexican in 2015, the home was on the market that year for $12.5 million, listed by McDonald.

The estate — at 5200 Old Santa Fe Trail, near Zia Road — has horse stables with eight stalls, along with an equestrian arena and bridle paths, and a caretaker house with two bedrooms and two bathrooms, a kiva fireplace and hardwood floors, according to a website called 5200 Old Santa Fe Trail.

Another 1,400-square-foot guesthouse also has two bedrooms and two baths.

Sitting just north of the Quail Run Golf Course, the property continues the golf theme. It has a green with five tee boxes — at 60, 90, 130, 150, and 175 yards — as well as an indoor golf simulator, swinging cage and putting green, the website says.

The property also has a pool with a spa and bathhouse, and an outdoor kitchen with a built-in grill, pizza oven and fireplace. There is a courtyard with fruit trees and trickling fountains.

The original part of the main was built in the 1940s, according to Buddicea LLC, though a series of additions in the 1990s and 2000s expanded the home to its current 10,000 square feet. The home has three bedrooms, six bathrooms, three private offices, six indoor fireplaces, a second-floor home theater and entertainment area, and three-car garage.

A separate, free-standing garage holds nine vehicles.

“No detail was overlooked in the architecture — from the hand-forged wrought iron railings, diamond trowelled plaster walls, and custom cabinetry to floors of imported stone, marble, ceramic tile and hardwoods including hickory and quarter sawn oak,” says the 5200 Old Santa Fe Trail website.

“Large windows and skylights, custom draperies, light fixtures and wooden beam vegas and latillas also add to the unique beauty of the interiors,” the site continues.
