The owners of the whole building unanimously agreed not to invite a property management company.

Is there only one building or multiple buildings in your community? If there is only one building, it will be a big deal. Let the property go out without his services and property fees. If there are many buildings in your community, and only one agrees not to invite them, it is unnecessary, because your building is an inseparable part of the community, and the road you take is the community's. The sewage from your building is discharged into the sewage pipe of this community, and the sewage from your toilet is discharged into the septic tank of this community. The greening property below your house needs maintenance ... it's hard for you to separate your building anyway. Unless you find another way, don't take the road of the community. Your sewage will be blocked and won't flow into the pipe network of this community. Your toilet will not be blocked and won't be used.
