I do not think that an investment done on land development can result to no profit at the end of day
Exactly, no investment done on land that will be a waste on the longer run, because in places like the riverine areas in the niger delta, opportunities are always there due to the fact that companies and major business are just coming into the area because it's an oil rich region, so all those rivers that are being sanddfill now might look very costly and expensive now, but in year to come when schools, hospital and most of this companies have establish fully, you as an individual will be very happy with yourself that you took the risk of investing so much on a river then, just to secure a land for yourself.
Let take the riverine context away from this and major it on lands in general, there's no way a land can get undervalued as the years goes irrespective of location. Instead it appreciates in value with time. That's why you can see people confidently buy land in unpopular or interior areas with the calculation of either reselling in the future for higher price value or developing on the land. For such long projection clients would be more comfortable owning these lands through a well trusted real estate firms to ensure land security.
