Results of Ketu in the 4th House
Ketu is a malefic planet, so here it tends to bring confusion, sudden losses, feeling lost, and unexplained anxieties focused on mother, home, comforts and inner happiness. As an angular (kendra) house, this placement strongly shapes the overall life direction.The exact result depends on which sign Ketu occupies here and the aspects it receives.
When It Activates
These results typically surface during the Vimshottari mahadasha or antardasha of Ketu, and when transiting planets trigger the 4th house. A well-placed Ketu here supports a happy home, property, vehicles and emotional contentment; when afflicted it can indicate domestic unrest, property disputes and an unsettled inner life.
