What is the ruling on purchasing a land grant application number from someone and agreeing with them that the title deed will be transferred in the buyer's name after the grant is issued and the remaining amount is paid?

This sale is void because the land is not owned by the seller, nor can he deliver it. It is merely a promise from the state to grant it to him, and it has not yet truly become his property. The Prophet, peace and blessings be upon him, said: "It is not lawful to combine a loan and a sale, nor two conditions in one sale, nor profit from what has not been guaranteed, nor to sell what you do not possess." The man must return what you paid him until he takes possession of the land allocated to him, and then he may sell it to you at that time for whatever you both agree upon.
