The Puerto Rico Planning Board granted final regulatory approval for a $2 billion-plus resort and residential complex on the island's southwest coast, clearing Reuben Brothers and Three Rules Capital to break ground on a dual-brand property anchored by Mandarin Oriental and Rosewood. The project marks the largest hospitality capital commitment to Puerto Rico's less-developed western shoreline since Hurricane Maria.
The development spans approximately 1,200 acres near Lajas, a municipality 90 minutes southwest of San Juan by car. Site plans call for a Mandarin Oriental flagship with roughly 200 keys, a smaller Rosewood property with 150 rooms, and a mix of branded residences totaling 400-plus units. Construction is expected to begin in Q2 2027, with the Mandarin opening targeted for late 2029 and the Rosewood following six to eight months later. Reuben Brothers acquired the land parcel in 2024 for an undisclosed sum after a multi-year entitlement process.
The approval matters because it validates Puerto Rico's shift from metro San Juan concentration to distributed luxury supply across the island's coastal perimeter. The southwest region has seen minimal branded hotel investment since Dorado Beach's Ritz-Carlton Reserve opened in 2012, despite consistent airlift growth into Aguadilla's regional airport 30 miles north. Mandarin Oriental currently operates zero properties in the Caribbean outside of Canouan in the Grenadines, making this a beachhead for the brand in a tax-advantaged U.S. jurisdiction with Act 60 residency incentives. Rosewood, which opened Dorado Beach in 2022 after acquiring the management contract from Ritz-Carlton, now positions two properties within two hours of each other, creating a micro-network effect for family-office principals splitting time between the island's north and south coasts.
The project's residential component is structured to absorb 60-70% of total development cost through pre-sales, a financing model Reuben Brothers has deployed across London and Miami mixed-use projects. Branded residence inventory is being marketed at $1,800-$2,400 per square foot, targeting buyers eligible for Act 60's 4% income tax cap and zero capital gains on Puerto Rico-sourced income. Developer economics depend on selling 250-300 units before the hotels open, a threshold that determines whether construction debt converts to permanent financing or requires mezzanine capital at higher rates.
Operators and allocators should watch three near-term events. First, Mandarin Oriental's formal franchise agreement filing with Puerto Rico's Tourism Company, expected by Q4 2025, will clarify brand fees and performance guarantees. Second, Reuben Brothers' debt syndication process, likely to involve $800M-$1B in construction financing split between U.S. regional banks and offshore lenders, should close by Q1 2026. Third, pre-sales velocity in the branded residence towers—tracked through Puerto Rico's public property records—will signal whether the project can self-fund or needs additional equity.
The southwest coast now holds three approved luxury projects totaling $4.2 billion in stated investment, none yet vertical.
