Ownership of property in the United States does not create a path to citizenship. Your neighbor must first become a lawful permanent residence. Lawful permanent residence is typically acquired through a petition filed by a family member or employer. Assuming your neighbor has a path to residence, he would need to spend most of his time in the United States until he became a citizen (which in most circumstances is after one has been a resident of the United States for five years).
