Property Muhurta and the Natal 4th House

Mars is the karaka of land and buildings. The 4th lord's sign, house, and dignity describe whether property holds. A purchase timed in the mahadasha or antardasha of the 4th lord, or of Mars, meets the chart halfway. Mars owns seven years. If the 4th lord is Venus, the natal window is inside a twenty-year mahadasha, and the antardasha is the product of those years divided by 120. Choosing a pretty Thursday while the 4th lord's period is years away asks the muhurta to do the natal chart's job. Jupiter's aspect on the natal 4th helps the purchase feel supported. It is still an aspect in the birth chart, not a quality of the afternoon.

The muhurta lagna should not put the 4th lord in a severe dusthana if a stable home is the aim, and the dhruva nakshatras are chosen because muhurta tradition uses them for acts meant to endure: planting, founding, and settling. Movable nakshatras suit travel and change, which is a poor match for a house you intend to keep. Avoid a tithi or karana the family priest flags, especially Vishti, called Bhadra, when the local panchang shows it. The panchang day follows sunrise. Under Asia/Kolkata the clock does not shift for daylight saving, but Mumbai's sunrise is not Kolkata's, so a muhurta copied from another city's app can be off by a whole tithi boundary.

The 4th house includes the feeling of occupying the place, not only the deed. A chart with the 4th lord in the 12th may buy at a distance or spend heavily on the place, and a good muhurta will not relocate that lord. Vastu of the plot is a third layer, directional, and independent of both dasha and tithi. Jyothish SI casts the natal 4th from the birth time with Lahiri ayanamsa. It does not publish a universal list of lucky dates, because those dates are city-specific and expire with the Moon. Ask for the 4th lord's period, then ask a panchang for one city's dhruva window inside that period.
