As a real estate investor, you buy land 'in the bush', then wait for capital appreciation.
Presently, lands at Ibeju Lekki are the fastest in Nigeria as a whole in terms of development and thus capital appreciation.
You might not have millions of millions to invest right now as the best time to buy a land was 20 years ago, the next best time is NOW.
But with 500k to 12 million naira, you can invest today and wait for just 2 to 5 years and see what happens. If you don't buy now, that 5 years will still come and go and you will still have to spend that money anyways.
Lands at this axis appreciate over 200% within just a year because of the rapid development happening in this axis as a result of the presence of governments, international and local companies. You need to come and see this place to understand what I am talking about.
