Private Island Investment Guide
Islands are scarce real assets with high holding costs and thin liquidity. Returns, where they occur, usually come from doing something to the asset rather than from waiting.

Routes to value creation
- Obtaining planning consents that did not previously exist
- Building access infrastructure that materially improves usability
- Establishing or improving a licensed hospitality operation
- Resolving title or tenure defects that suppressed the price
- Subdividing or restructuring where the jurisdiction permits it
Risks specific to islands
- Small buyer pool and long sale timelines
- Climate and catastrophe exposure, including insurance availability
- Regulatory change affecting foreign ownership or tourism licensing
- Currency and repatriation constraints in some jurisdictions
- Concentration risk from holding a single indivisible asset
Underwriting discipline
Model the full holding period including annual operating costs, capital replacement and a realistic sale period. Test the outcome against a scenario where no consent is granted and no operating income materialises.
