The final stage of CRE transactions is closing and post-closing, which involves finalizing the terms and conditions of the deal, signing the documents, transferring the funds, and updating the records. AI can facilitate and expedite this stage by using NLP and ML to generate and review the documents, such as contracts, invoices, and receipts, and ensure compliance with the regulations and standards. AI can also use ML and DL to automate and secure the payment and settlement processes, such as blockchain, smart contracts, and digital wallets, that can verify the identity, authenticity, and ownership of the parties and the property. AI can also use ML and DL to monitor and manage the performance and maintenance of the property, such as sensors, IoT, and cloud computing, that can collect and analyze data, provide insights, and trigger actions.
