Ok let me ask you, if you purchase a land legally in your locality, everything pertaining to ownership is transfered to you, the rest decisions is left for you wether to start developing the land or start using it for agriculture, so even if you decide to give it out for rent, it's your business because it's now yours.
No need to ponder on this question because it's self explanatory, once you have completed your payments which is the thing that makes you the owner of the property, pending when your documents will be fully documented the land automatically becomes yours and you decide what you want to do with the land.
If you decide to start using it for agriculture I don't think LandDAO will stop you since you are now the sole owner of the property but it the agreement says you can only develop the land and not engage in any agricultural practices, then the investor must abide by the agreement.
