Career
Liam chose a very different path from his father. Instead of acting or working in Hollywood, he went into real estate.
Career Details

He has been linked to the Frankel-Bell (sometimes called Frankel-Ball) Realty Group in Palm Beach, Florida.

The company works with luxury homes in one of the richest parts of the country.
-
Some reports also say he has worked for companies like Aspen Skiing Company and NFP (insurance and investment firm).
⚠️ Important Note: His name does not appear on the current Frankel-Bell company website. This means he may have worked there in the past or that some online reports are not accurate.
Where Does He Live?
Different websites say different things about where Liam lives:
-
Palm Beach, Florida – fits with his work in real estate.
-
Los Angeles, California – fits with his father’s Hollywood career.
Because Liam is so private, it is hard to confirm which is true.

| Build | Slim |
| Hair | Brown |

These details mostly come from smaller biography websites and are not confirmed by major news outlets.
Net Worth
There are many different claims about Liam’s net worth:
-
$1–8 million → This is the range most often reported. It likely comes from his real estate career and the trust fund his father set up.
-
$800 million → Some websites say this, but it is almost certainly false. This number is probably confused with the wealth of his step-father, Bill Koch, or the Rooney family.
The truth is most likely closer to the lower range.
Common Misunderstandings
Because Liam lives so privately, there are many mistakes in online stories about him:
-
Birthdate confusion: November 15 vs. October 15, 1996.
-
Youngest child claim: Some sites wrongly say Liam is Kevin’s youngest child. This is false because Kevin had three younger children with Christine Baumgartner.
-
Career confusion: Often listed as working for Frankel-Bell Realty, but he is not currently on their roster.
-
Exaggerated wealth: Claims of $800 million are misleading.
Why People Find Him Interesting
Liam is not like many children of celebrities. Instead of seeking fame, he has:
-
Built a life in business rather than acting or music.
-
Stayed away from social media and tabloids.
-
Kept his personal life very private.
-
Managed to avoid the scandals that often follow famous families.
In many ways, Liam is the opposite of the Hollywood stereotype.
Conclusion
Liam Costner may be the son of a Hollywood legend, but he has chosen a very different life. Born into fame and fortune, he could have lived in the spotlight. Instead, he focused on privacy, independence, and business.
With ties to both the Costner family of Hollywood and the Rooney family of sports, Liam represents a unique blend of two American dynasties. Yet he is proof that being born into fame does not mean you must live in it.
Liam’s story is about quiet success and personal choice. While the world watches his father on screen, Liam has built a life in the background—one that belongs entirely to him.
