In a previous shiur , we explored the nature of the bar metzra rule, that a neighbor who possesses land adjacent to land being offered for general purchase has first rights to purchase the land. Does this reflect a benefit that can be expressed in his right to demand “first purchase” and oust alternate clients, or does the neighbor enjoy a partial kinyan on the land?. In this shiur, we will investigate several additional nafka minot that would be impacted by this essential question. In particular, we will study the case of Ravina and Runia presented in Bava Batra through the lens of this question.
