In the realm of luxury real estate, few names carry as much weight as Paul Allen, the Microsoft co-founder and former owner of the Seahawks.

One of his most remarkable holdings, a collection of properties on Mercer Island, was recently sold for an impressive $67.1 million.
This sale is part of an ongoing effort to liquidate Allen’s extensive property portfolio. The Mercer Island estate, which includes two waterfront mansions and several other homes, is situated on the island’s western edge, offering stunning views and a taste of luxury. This article delves into the specifics of these properties, their history, and their place within Allen’s larger real estate empire. Join us as we explore the world of lavish living and extraordinary real estate transactions.

Mercer Island Mansions Sold by Paul Allen’s Estate

Continuing the legacy of the late Microsoft co-founder, Paul Allen’s estate recently sold multiple properties on Mercer Island, near Seattle. The transaction included six houses and two additional land parcels, totaling an impressive $67 million.
Among these properties were three expansive mansions, each exceeding 10,000 square feet (929 square meters). These remarkable homes are located on or near the island’s picturesque western coast, providing residents with breathtaking views and unparalleled privacy and tranquility.
An intriguing story surrounds one of the mansions Allen purchased in 1983. In 1990, he faced a legal battle with the city of Mercer Island over the approval of a significant remodel.

This sale follows closely behind the recent transaction of two New York apartments owned by Allen’s estate, part of the ongoing reduction of his vast property holdings. These sales continue to attract attention from luxury real estate enthusiasts and market observers.

Allan Island: A Testament to Paul Allen’s Vision

The Teton Ridge Ranch

In 1993, Paul Allen expanded his horizons by purchasing a former sheep ranch in Tetonia, Idaho.

Allen transformed this rustic ranch into the Teton Ridge Ranch, a five-suite luxury mountain lodge that operated until 2009.
This venture was a distinct departure from his coastal lifestyle, highlighting his appreciation for the raw, untamed beauty of Idaho.

The Enchanted Hill

In 1997, Allen purchased “The Enchanted Hill,” a Beverly Hills estate formerly owned by Hollywood legends Frances Marion and Fred Thomson, for $20 million.

The land remains vacant, with only terraced hillsides hinting at Allen’s grand but unfulfilled vision for the site.

Thurston Estate in Hawaii

Adding to his diverse portfolio, Allen purchased the historic 10-acre Thurston Estate in Kailua-Kona, Hawaii, for $7.5 million.
