Fighter jets flying over a house are most commonly due to military training exercises or routine pilot training near a military base or training area. Pilots need to maintain flying hours, practice maneuvers, and keep their skills sharp, which often involves flying over nearby areas. Sometimes they are practicing takeoffs, landings, aerial combat, or other missions. The frequency can increase during scheduled training periods at nearby air bases or military facilities. If the house is near such a location, the jets flying overhead are likely part of these routine operations or training exercises rather than any cause for alarm.
