I work with Boundless multiservice solution Nigeria limited as a freelance marketer. The company is a real estate company with headquarters in Lagos.
They sell lands and investments. Investment in the sense that, you invest your money with them and after some months depending on your agreement you get back your capital and interest. The money is used to purchase new lands and resell, that is where your interest comes out from.
You get 15% as interest in 6months, 35% in 12months, 70% in 24 months.
There are lands in Lagos, Oyo, Ogun, PH, Anambra, Abuja, Enugu and other states.

That idle money in bank will be eaten up by useless deductions and charges, why not invest in real estate
