Moon in 7th house.

So, lets see what Moon can do in 7th house without any conjunction or aspect from any other planet. 1st lets see what these 2 things represent -

Moon represents Mind, Emotions, Mother, Local Government, Peace of Mind, Home Environment, Water, Milk etc.

7th house is house of market place, other people (masses), business partnerships, marriage, spouse, marital happiness etc.

House-wise, this is best position of Moon because 7th house is house of other people and masses and Moon is mind. So, this person's mind is very much concerned for other people. They like to see if everyone around them is in convenient position or not. Basically, a politician loved by people can easily be seen from this position. Their own happiness is not important to them as much as other's comfort. 

As 7th house is also house of Business and Moon is mind, so these people are very Business Minded people. They are good traders, merchants and best deal makers. As Moon also represents Mother, their mother can also be a very good business person. Even if she may not be a full time business woman but in routine life, she would have the best bargaining ability. 

As Moon is emotions and 7th house is house of spouse, these people are always emotionally involved with their spouse. Their peace of mind comes when they are able to emotionally connect with other people and their spouse. For spouse, they look for a person who can be like their mother. They also get impacted by others' opinions very quickly.
