The property fee before buying a second-hand house has not been settled.

Legal analysis: the original owner who buys a second-hand house needs to ask him to settle the property fee first. In order to avoid disputes caused by the original owner's default on property fees, in the second-hand housing transaction, the buyer should ask the seller to settle the expenses before the transfer, and all the expenses before the transfer shall be borne by the seller, and this clause shall be written into the contract. Under normal circumstances, buyers should set aside a part of the balance as a deposit when paying the house payment.

Legal basis: People's Republic of China (PRC) City Real Estate Management Law.

Where the land use right and house ownership are obtained due to the disposal of mortgaged real estate, the transfer registration shall be handled in accordance with the provisions of this chapter.
