On October 11, Shanghai Chainjia revealed that in the three weeks since its launch on September 16, the new service “Sincere Sale” has sold over 100 orders. Nearly a quarter of the properties sold were previously listed for more than 90 days, with an average listing period of 63 days; however, after being sold in good faith, the average transaction period was shortened to about 8 days. According to data from the China Index Research Institute, the average transaction cycle for second-hand housing in Shanghai in 2025 is about 102 days. “Sincere Sale” standardizes the most time-consuming negotiation process in second-hand housing transactions: the owner sets the three price levels of starting price, negotiable price, and psychological reserve price; each buyer pays a deposit of 50,000 yuan to a third party supervisory account; the buyer bids up to two times, and the transaction is automatically locked in when the bottom price is reached. The service excels in the two types of demand: replacement and offsite property sales. A replacement owner who has been listed for more than a year completed the transaction 4 days after entering the “Good faith sale”; while the offsite owner can complete the entire process of signing the contract online.
