The Land Department is preparing a new land appraisal round for 37 million plots, to take effect 1 January 2027 (the article says "ปี 2570"), covering 2570-2573. Early estimates put the national average rise above 10%, versus 8.93% last round, with central Bangkok (Silom, Phloen Chit, Rama 1, Witthayu) over 1 million baht per square wah. Land tax and development costs will rise, and REIC expects the largest gains along the orange and pink MRT lines. Owners holding land or property may see higher land tax bills; some are already selling. Buyers may shift to suburban townhouses and smaller condos.
