The closing statement that should be uploaded is the one that has been fully executed and includes all required signatures. This typically includes the signatures of the Buyer, the Buyer’s Agent, the Settlement Agent, and the Seller. The advisable document is usually the Buyer's Side Closing Statement generated by the Title or Settlement Company, as it ensures all parties have signed and agreed to the terms. Additionally, ALTA (American Land Title Association) statements are also acceptable as part of the documentation. Always ensure that the uploaded statement is complete and includes the necessary signatures to avoid any delays or issues in the closing process.
