The 11th house of the ascendant chart controls profits, gains, additions, relations with friends, social circles, connections, etc. Moon in the 11th house signifies additions or improvements to those aspects of the native’s life.
Since the 11th house controls gains and profits, the natives will gain heavily by the blessings of the Moon’s presence there, but only if She is not afflicted.
If the Moon is not in Her own sign (Cancer) or in exaltation (Taurus), then the capability of Moon to do good for the native depends on the strength of the lord of the 11th house. If the 11th house lord is situated in a malefic house or happens to be afflicted by malefic influences, then the native would only receive limited benefits.
Additionally, when not afflicted, the Moon in 11th house will provide the native with nearly all comforts of life, including vehicles, a good residence (or many residences), servants, excellent wealth, and more.
Also, the person will have very good social circle or even if they have a few friends, they will be trustworthy and close to the native.
Moon’s placement here will also cause its 7th aspect to fall upon the 5th house of the ascendant chart, which will also grant good chances for the native to find a loving partner (meaning, they will have good luck in finding love and a partner).
Such individuals will be able to attain a level of shrewdness and intelligence as businesspersons. Also, if such a person wishes, they can have children even in their advanced years (because Moon’s 7th aspect would fall the 5th house, which is the house of progeny, although the advanced years factor has to do more with their overall vitality which would be decided by Saturn and Sun’s placements in the chart since Saturn gives longevity and the Sun gives vitality and strength to the overall constitution of the person).
The only drawback of having the Moon in the 11th house is that the person may have children who will be very much born into luxury and therefore, they may not care to do much in their lives by themselves.
Aside from those, no other special considerations are needed for the 11th house.
