The 4th house represents fixed assets, residences, agricultural lands, real estate, properties, conveyances, relations with the mother, health of the mother, lifespan of the mother, domestic happiness, comforts within the residence, overall emotional health, and agricultural produce.
If Jupiter is well-placed (in His own sign or in a friendly sign) in the 4th house, the native shall have access to domestic comforts and he/she shall enjoy a peaceful and loving relationship with his/her mother. Such an individual will also have access to a spacious residence or they will come from a family with the resources to afford comfortable living accommodations. Such a person will also have multiple vehicles or conveyances; if they do not purchase any vehicles of their own, they will still have someone who will enable them to commute and enjoy the luxury of good conveyances (such as their father or a family member).
There is also a chance that a well-placed Jupiter in this house will give the person a relatively religious household, meaning they will have family members who may be interested in religious activities.
Any benefic conjunctions will further improve the positive effects of the 4th house. Some points to consider are:
Jupiter in 4th house in Cancer
This is applicable to Aries ascendants; in the 4th house, an exalted Jupiter will give the native access to an excellent and spacious accommodation. It will not be surprising even if they own multiple homes or residences and have all the comforts akin to a palatial estate at their home. Such an individual will also be from a religious background; the person will also have very good relations with their mother although their relations with father will be somewhat affected.
Jupiter in 4th house in Sagittarius
This is applicable to Virgo ascendants; this placement is even better for Jupiter than Jupiter’s exaltation in the 4th house for Aries ascendants because it provides all the comforts and luxuries of the household as well as domestic happiness from the residence without ruining or affecting the relations of the native with their father. Additionally, the person will own multiple real estate properties and also enjoy conveyances along with good relations with their mother. If the Moon is not afflicted in the chart of the person, the person’s mother will also live long and shall be in overall good health.
Jupiter in 4th house in Pisces
Jupiter in this placement will give a long life to the person, as well as good life to the mother of the native along with the usual pleasures of a comfortable household. However, this may result in the person receiving a bit of less help from their father about various property related matters.
