The site selection of TSMC's factory in the "Sacred Mountain that Protects the Country" has become a subject of much attention in the housing market in recent years. Yongqing Real Estate analyzed the administrative districts where TSMC will and has already entered the factory based on actual price registration data. Changes in the transaction price of second-hand houses in the past two years revealed that the transaction volume of TSMC houses has decreased across the board this year, with the largest decrease of nearly 70% in Zhubei City. As for the largest correction in house prices, it was 13.1% in Anding District of Tainan City.
In order to expand production, TSMC has set up factories in various places in recent years. Not only has it brought advanced process or packaging production capacity to the local area, but upstream and downstream suppliers, manufacturers, equipment manufacturers, etc. have also moved in. In addition, many well-paid engineers have settled there, which has overall driven up local consumption, rental housing, and even housing demand. Therefore, TSMC's factory establishment often affects the dynamics of the regional housing market.

Among TSMC’s major factory areas, Zhubei City’s transaction volume this year shrank by 69.6% compared with last year, making it the area with the largest decrease in transaction volume on the list. Chen Jinping, deputy manager of Yongqing Housing Research and Exhibition Center, pointed out that so far this year, due to the impact of bank mortgage tightening and the seventh wave of credit controls, housing market transactions have not seen an improvement.
Chen Jinping said that buyers currently have a conservative mentality when buying houses and expect a certain drop in house prices before they are willing to enter the market. However, the average unit price of ancient houses in Zhubei City this year has not decreased but increased compared with last year. The average house price has even reached the prefix 4, which makes many buyers stay on the sidelines. Therefore, the volume has shrunk most significantly, even 69.6% lower than last year.

Housing prices in some areas of TSMC have also begun to correct. Chen Jinping explained that housing prices in Tainan Nanke Park have risen rapidly in recent years, which has made many home buyers unable to afford it. The supply of houses around the park is large. As the impact of policies continues, many investors choose to leave the market for resale, which increases the supply of houses for sale. Data shows that Anding District’s housing prices have been revised down the most by 13.1%, followed by New Urban District’s correction of 3.7% and Shanhua District’s 2.8%.
Housing prices in Taibao City in Chiayi County bucked the trend and rose by 11.8%. Chen Jinping emphasized that in recent years, Taibao City has been subject to continuous development. Because TSMC will enter the Chiayi Science Park, the "Huatai Outlet City" Outlet won the bid for land in a specific high-speed rail area. The future development potential is promising. Benefiting from the low base period of housing prices and the support of buying by scientific and technological talents, local pre-sale prices have reflected market rising expectations, driving up the price of second-hand houses.
