Land owner/lessor must invest partly in project for which the land owner will receive 12% return p.a. This is to ensure that that land owner does not decide to suddenly ask our company to vacate. To provide comfort to the land owner, the company will also invest partly in the project, to prove the company also won’t vacate. Minimum 8 yrs lease.
