Tainan Existing-Home Prices Fall 4.88% in Q3, the Most Among the Six Special Municipalities, While Average Residential High-Rise Prices Rise Year on Year for 5 Straight Months

The Sinyi Housing Price Index shows that the national existing-home price index stood at 168.64 in Q3 2026, down 0.08% from the previous quarter and down 0.05% from a year earlier. Tainan's decline was markedly larger, at 4.88% quarter on quarter and 3.38% year on year, the biggest drop among the six special municipalities and Hsinchu County and City.

The direction of Tainan's official statistics is the opposite. Data from the Tainan Actual Price Website show that since April 2026, the city's average residential high-rise price has been higher than a year earlier for 5 consecutive months, with year-on-year growth between 2.23% and 10.7%, staying at a figure starting with 3. The Tainan Housing Price Observatory, which excludes presale transactions and outliers, also shows the average high-rise sale price rising year on year over the past 5 months; Annan and Anping districts have also posted positive growth over the past 4 months, with relatively small fluctuations among the districts.

Zhang Rong, associate director of the Sinyi Realty Tainan Minsheng branch, explained that the Sinyi Housing Price Index covers only existing homes, excluding presale homes and newly completed homes, and that sale prices and volumes for Tainan existing homes have been largely consolidating over the past two years, with weak momentum to push higher. He noted that although the official observatory's data exclude presale homes, they should include newly completed homes, so prices hold up better; he speculated that Annan and Anping, where newly completed homes make up a higher share, have smaller fluctuations for the same reason.

Sinyi Realty experts said that after excluding presale and newly completed homes, existing homes lack upward momentum, but the economy still provides support, and with steady owner-occupier demand every year, the market is mainly consolidating, with room to negotiate generally within 10% and no sharp collapse.

Zhang Rong mentioned that with AI and the tech industry thriving, a good deal of capital has flowed into the stock market, and some of it may return to the housing market later; the number of buildings with ownership transfers nationwide has stayed between 260,000 and 350,000 over the past three years. He believes Tainan's housing market is consolidating rather than collapsing, and that for first-time buyers and those trading up, prices are currently easier to negotiate and there is a wider range of properties to choose from.
