My question involves real estate located in the State of: Texas

My neighbor is selling me about half an acre of his land that currently borders my property. He is planning on tearing down his house, which currently is partially on the land to be sold. He would like to convey the land initially to me under a perpetual easement, so as to facilitate the demolition process. I would retain the opportunity to have the land replatted into my current property at a later time.

Does this sound like a reasonable plan? Any comments on advantages/disadvantages of this approach? Thanks for any thoughts.
