The village schoolteachers kept a small lending library in the front hall, open to the neighborhood, with books borrowed and returned in various states, with dedications signed on the flyleaf. The house of origin was also a crossroads, a place ideas and strangers passed through. The Imum Coeli (IC) is the chart's lower angle, the nadir point, not the cusp boundary of the fourth house, and in Sagittarius it points to an inherited substrate with a wide horizon, with migrations perhaps, with long after-dinner talk about philosophy or politics or religion, with a root that did not stay on one piece of land. Jupiter shows itself here at the base of your chart, which means the house you came from smelled of books, of travel, of humor, of beliefs argued out loud. Your private self inherits that breadth: you settle in a house with windows, a growing shelf, a long project on the desk. The cost isn't inherited optimism; it is mistaking openness for always being on the way out, turning your house into a place to pass through so you never have to live the near thing. The horizon is also inside the small rooms. Look at whether your home lets you stay, or whether everything in it pushes you toward the next departure. Stay long enough to plant something.
