I think as long as God is not creating more land, the land will continue to appreciate. Unfortunately this appreciation is not reflected in small towns or farming land. For instance I bought an acre somewhere 153 km from Nairobi, which is very fertile at 150k and 5 years down the line, the land around is costing about 180-200k. On the other hand, a plot i bought in juja at 380k 3 years ago is now fetching more than double the amount.
My greatest fear is for communities whose land is held as trust since the trustees continue to sell the land while the community doesn't have titles. This is what triggered MRC uprising in the coast where foreign investors have land and titles while the natives are considered as squarters
