The Real Estate Information Center (REIC) of the Government Housing Bank (GHB) has conducted an analysis titled "Index of Vacant Land Prices Before Development in Bangkok and Surrounding Areas – Q3 2025", which shows that the index value is 447.2 points, an increase of 7.7 percent compared to the previous quarter (QoQ) and an increase of 14.3 percent compared to the same period last year (YoY). This marks the first time in 10 quarters that growth has exceeded 10.0 percent since Q1 2023, indicating a continuous upward trend in vacant land prices before development, especially in high-potential locations along the subway lines and areas with infrastructure development, such as Bang Phli–Bang Bo–Bang Sao Thong, which saw a price change rate of up to 44.0 (YoY) . This includes land along the Green Line subway routes from Samut Prakan to Bang Pu and Bearing to Samut Prakan, which experienced a price increase of 26.1 percent. The details are as follows:

The top 5 locations with the highest land price growth rates in Q3 2025 compared to the same period last year (YoY) are as follows:

Rank 1 is land in Bang Phli–Bang Bo–Bang Sao Thong, with a price change rate of
44.0 percent due to its status as an industrial and logistics area that continues to grow, close to the airport, and easily accessible to the city and EEC.

Rank 2 is land in Bang Kruai–Bang Yai–Bang Bua Thong–Sai Noi, with a price change rate of 26.4 percent.

Rank 3 is land in Samut Prakan–Phra Pradaeng–Phra Samut Chedi, with a price change rate of 26.1 percent.

Rank 4 is land in Nonthaburi–Pak Kret, with a price change rate of 22.8 percent.

Rank 5 is land in Lat Phrao–Bang Kapi–Wang Thonglang–Bueng Kum–Saphan Sung–Khan Na Yao, with a price change rate of 21.4 percent.

The changes in land prices in the top 5 areas reflect a clear increase in land values in the periphery areas in line with urban expansion, particularly in Samut Prakan province, which has been supported by the new master plan that took effect on August 22, 2025. This plan has revised land use regulations and increased the areas designated for high-density residential and commercial activities, significantly enhancing the development potential and land value in Samut Prakan. Meanwhile, the suburban areas of Bangkok and its periphery, which have much lower land price bases than the inner city, still hold potential for developing horizontal housing projects that align with consumer purchasing power, leading to continuous demand for land and resulting in higher price increases in suburban areas compared to the inner city.

For vacant land prices before development along the subway lines in Q3 2025, the top 5 subway routes with the highest land price growth rates compared to the same period last year (YoY) are as follows:
