What's the charge for buying one and getting one free?

The general practice is to look at the complimentary floors, which are not included in the property management fee area, but need to be paid if included in the fee area. Of course, you can make an agreement with the property. In addition, the charge is based on the construction area indicated in your house purchase contract and the construction area indicated in the real estate license. If the building area indicated on the property certificate does not include the gift area, you can not pay the fee. The projects I have experienced include buying the top floor and sending it to the attic, but if the property management company charges, the attic is generally not included in the charging range.
