When the ruler of the fourth house is in the fourth house, this means that parents featured strongly in your life, and this could be because they really focused on your upbringing.
Whether this had positive or negative results very much depends on the condition of the fourth house and its ruler.
If it’s afflicted, this could show strict parents, enslaving you into routines you hated. If it’s not afflicted, it means that your upbringing, which your parents put much effort into, produced wonderful results.
This placement may mean that parents are important people. It could mean that they own land, or live in their own house or apartment rather than living in a rental property.
Depending on whether or not this astrological combination is afflicted, having your own family will be a curse or a blessing. But you are likely to be drawn into forming a family as though by fate, even if you didn’t plan it.
The ruler of the fourth house in the fourth house means that your old age, especially the last years of your life, will be very important. For example, they may be important for your personal development, or your life would be more intense or highlighted then.
You are likely to be a grounded person, such as achieving such stability through long-established routines, parental upbringing, or genetics.
You are likely to be involved in land and property in your life, such as owning your own land and property, being involved in property business, farming, dealing with the natural resources of the earth, and so forth.
Your country of birth will strongly feature in your life. That may manifest as you living in your country all your life, living in a parental property, or having strong bonds with your country through your work or parents, for example. Whether this brings benefits or misfortunes depends on the condition of this astrological configuration.
Finally, this placement sometimes highlights inheritance, such as you inheriting excellent property from your parents, or the inheritance that you get is what will often be on your mind because of some reason; such as it bringing many troubles or benefits, for example.
