Diane Keaton leaves behind a staggering net worth of $100 million.

The Oscar winner, who died at age 79, starred in a slew of hits, including “The Godfather” trilogy, “Father of the Bride” and its sequel as well as “The First Wives Club,” but she was also a savvy real estate flipper, specializing in restoring historic homes.

Keaton had a deep appreciation for architecture and design, especially Spanish Colonial, Mission Revival and mid-century modern styles.

Several of her flips were sold to fellow celebrities, according to Celebrity Net Worth, including a 100-year-old mansion that she bought in 2007 for $8.1 million. Three years later, she sold it to “American Horror Story” producer Ryan Murphy for $10 million.

In 2002, the “Annie Hall” star purchased a Bel Air home for an undisclosed amount. After renovations, she sold the home to a tech exec for $16.5 million in 2005.

A Laguna Beach property was bought for $7.5 million in 2002, renovated, and then sold just two years later for $12.75 million.

In 2017, Keaton released a design book, “The House That Pinterest Built,” which was described as both a “style guide” and “an inspirational tome.”

Keaton shared that when she wanted to build her own home, she took the advice of her “Something’s Gotta Give” director, Nancy Meyers, and took to the boards of Pinterest for inspiration.

“If you want to explore. If you love to see. If you’re looking to look, this book is an example of a home made from the gifts of other people’s addictive yearnings for the perfect home, with the perfect landscape and the perfect interior,” Keaton wrote.

Although Keaton’s cause of death has not been announced, there was one foreboding sign in March when she listed her “dream home” in Los Angeles for $29 million. She had previously stated that she planned to remain there permanently.

She is survived by her two children, daughter Dexter and son Duke.
