The geomantic omen of a house, no matter who owns it or whose real estate license is, only affects the people who live in it. The longer you live, the more obvious your influence will be.
So even tenants, if the landlord doesn't live in this house, the geomantic omen of the house will only affect the tenant, but not the landlord.
If your daughter and her parents live in this house, Feng Shui will affect them at the same time.
However, there is a more detailed analysis in Feng Shui, that is, the figures represented by each party are different. For example, the problems in the northwest will be fulfilled in the father. Similarly, the southwest represents the mother and daughter 2 1 year-old, which will be greatly influenced by the geomantic omen in the southeast of the house.
