I have a friend who bought a plot of land for N1,050,000. He just wanted to test the water with land banking.
After 6 months he said he wants to sell the land even for same amount and it has been over a year now, no buyer and the agent that sold the land to him is not even picking his call as regard reselling the land.
If you're not liquid enough don't ever buy a land else you will cry blood.
