can personal property be removed from a house that is part of an estate? ?

No personal property should be removed from the estate if it is not part of the planned distribution of the estate. Depending on the wording of the Will, the personal property may go with the house, or may be distributed to specific individuals.  If you are a court appointed administrator, and you are at the point where other people are stealing personal property from the estate, you should proceed very carefully to ensure that no one makes a claim against your for failing to secure the property, or breaching your fiduciary duty.  If property was stolen, file a police report.
