Astrological combinations that favor selling a house include the presence of the 4th House lord in the 2nd or 11th House, which indicates gains from property. If Mars, the planet governing real estate, is well-placed or aspecting the 4th House, it further supports property transactions. Additionally, a strong 3rd, 5th, 10th, and 11th House can indicate a successful sale, as these houses relate to effort, gains, and fulfillment of desires.
