Self-storage is the latest enterprise to deliver rental returns to small Australian investors, reports The Sydney Morning Herald. Hot on the heels of boutique property plays such as car-parking spaces, ATMs and telecommunications dishes comes the storage facility. A "guaranteed" high return of 8 percent and exciting prospects for capital growth almost sounds too good to be trueespecially for a property segment in its fledgling stage (by U.S. standards). Australian storage has been around for 30 years, but now the small investor can enter this market by investing in a property trust or buying a single-strata facility.
