if u r buying a plot, have a plan first i.e what do u want to do with the plot? develop rental units or shops/ how much will u make as rent? once you come up with the plan, buy the plot and immediately seek for construction financing because just buying the plot without constructing on it will not generate income. most banks give 80 to 100% financing on a good feasibility study and when you own the plot.
