When the building was built, the property said that the building was built in three square meters, and it was necessary to pay three square meters. Should I pay the money?

First of all, the money is definitely not collected by the property, but should be collected by the property, which is only responsible for the property management of the community. Secondly, whether to pay or not depends on how your commercial housing sales contract is agreed. The housing area error is agreed. Within a certain range, we should refund more and make up less according to the unit price. If it exceeds this range, the owner will not have to pay. Finally, this area is not said by the property, but depends on the actual surveying and mapping area, that is, the area on the real estate license.
