Palm Beach Developer Nets $9M Profit on Waterfront Flip

Developer Mosie Miller has closed a profitable waterfront transaction in Palm Beach, selling his renovated property at 1246 North Lake Way for $30.8 million. The sale represents a substantial gain from his 2023 purchase price of $21.6 million, marking another successful flip in South Florida's luxury residential market.

The 4,700-square-foot residence, originally constructed in 1962, sits on 0.3 acres and features five bedrooms, seven bathrooms, one half-bathroom, a swimming pool, and private dock access. Miller and his wife Michelle undertook extensive renovations before listing the property for $34.9 million in November 2024, according to market data.

Christian Angle of Christian Angle Real Estate represented the sellers, while Margit Brandt of Premier Estate Properties brought the purchasing party. The buyer's identity remains undisclosed as deed records have not yet appeared in public filings. The property spent more than a year on the market before finding its new owner.

Miller has established himself as a prominent figure in Palm Beach County's luxury development sector. His recent portfolio includes the 2023 sale of an oceanfront spec mansion at 149 East Inlet Drive for $68.1 million, a property he developed after acquiring the site for $14.6 million in 2017. That same year, he sold a custom home in Palm Beach Gardens' Old Palm Golf Club to BET co-founder Robert Johnson for $20 million.

The Miller family's real estate activities extend beyond Mosie's development work. His father, marina owner Robert Miller, purchased a $25 million residence in the Mar-a-Lago Security Zone in February, demonstrating the family's continued investment in premium Palm Beach properties.

This transaction contributes to Palm Beach's robust luxury sales activity this season. Former Red Bull COO Gary Smith acquired a waterfront mansion for $55.2 million earlier this month, while March saw two significant deals: the family of late McDonald's expansion executive George Cohon sold a waterfront lot for $27.5 million, and Fordham University trustee Kim Bepler purchased a lakefront home for $30 million.

The consistent flow of high-value transactions reflects Palm Beach's enduring appeal among affluent buyers seeking waterfront properties. The island's limited inventory and prestigious location continue to drive competitive pricing, with developers like Miller capitalizing on renovation opportunities to meet market demand for updated luxury residences.

Miller's successful flip demonstrates the potential returns available to developers with renovation expertise in Palm Beach's exclusive waterfront market, where properties commanding eight-figure prices have become increasingly common.
