A neighbor with a 40,000 SF lot is selling the lot. The back side of his
lot line is the back side of my lot line. I have always wanted another 50'
of my backyard so I am thinking that is about 5000 SF. Is it possible to
make an offer to buy that 50' from his lot does that require him to split
his lot into a big piece and a tiny piece first? How would one go about
doing this if it is even possible?

Thanks in advance,
