What this rule checks
Source: Shanker Adawal, Encyclopedia of Vedic Astrology: Yogas. Chapter 16, section 6(i), printed p.359 (PDF381). Ayatna Griha Prapti Yoga, SECOND variant: D1 H9 lord in a natal kendra (H1/H4/H7/H10) AND D1 H4 lord in own sign or exaltation. This is a complete source alternative. The first variant’s benefic-aspect condition is not required here. The source links it with acquiring house property with less effort, without specifying funding route or timing.
