Special economic zone (SEZ) Dube TradePort says its long-term leasehold model allows investors to access land over long periods without the need to buy it outright and ensures that it has a stable revenue stream over the lease period. The SEZ has noted a growing awareness and interest in the benefits of a long-term leasehold ownership model and has had one in place for the past ten years, says Dube TradePort SEZ property investment head Andile Mnguni.
