He who is literally in the occupation or possession of the land, as distinguished from the owner out of possession. But, in a more technical sense, the person who is seised of the land, though not in actual occupancy of it, and locally, in Pennsylvania, one who purchases and takes land subject to the existing lien of a mort- gage or judgment against a former owner.
