How to move rooms from one house to another

 En español aquí.

Very important to keep in mind:

A room can only be moved to a room that you have not purchased.

EXAMPLE:I want to move a room from house 4 to house 9 but I have already bought all the rooms in house 9. 

What I have to do is make sure that there is a room to buy/build in house 9 and I will do that by moving a room that is without building from another house to house 9. In this case of the 10th house

To move the room I have to click on Edit room (1), click on the room that I want to send to house 10 (2), click on the tool pencil (3) and in the box that opens click on that Move room (4) and send it to house 10 (5).

This will appear in the place of the room that I moved

Now I can move the room from house 4 to house 9.

TIP: When you move a room, the unbuilt room is always placed in the place where it was. But you cannot move the unbuilt room in the house, which prevents the reorganization of the others.

My advice is that before moving a room to another house, place it at the top, so there will not be an unbuilt room among the others.
