Dallas entrepreneurs Melbourne and Jamie O’Banion listed their Highland Park mansion for $24.9 million on Mar. 26, according to public records. The property, located at 4815 Saint Johns Drive, is being marketed by Allie Beth Allman of the Dallas luxury brokerage Allie Beth Allman & Associates.
The six-bedroom, eight-bathroom home was built in 2020 and spans 11,433 square feet on a 0.6-acre lot. The listing price equates to about $2,200 per square foot.
Melbourne O’Banion serves as CEO of Bestow, a Dallas-based software startup focused on life insurance carriers. Jamie O’Banion is the founder of BeautyBio, a cosmetics company also based in Dallas.
The O’Banions’ listing joins several other high-priced properties that have recently come onto the Texas market this spring and late winter. Another agent from Allie Beth Allman & Associates is representing Hadley & Bess for a spec home at 10010 Strait Lane with an asking price of $25 million. In February, Texas saw its most expensive new residential listing with a $25.5 million spec mansion at 4 West Lane in Houston.
These homes are among the highest-priced currently available on the public market in Texas. Only a few properties surpass the O’Banions’ asking price: notably the Cox Family’s Crespi Estate at $64 million in Dallas; Colleen Romanov’s Lodge at Hunters Creek at $49.9 million in Houston; Blantyre Homes’ spec mansion at $34.5 million; Larry Lacerte’s home at $29.9 million; and Cary Maguire’s estate at $27 million—all but two located in Dallas.
