How to interpret:
- All segments start at 100 in 2015.
- Resale condo prices in districts 9, 10, and 11 initially saw flat or mild growth from 2015-2017, followed by a steady uptrend from 2018.
- Resale landed property prices rose more quickly, especially from 2020 onwards, reflecting higher demand and tighter supply.
- By 2025, landed homes in all three districts significantly outperformed condos in price index growth.

Summary:
- Landed properties in districts 9, 10, and 11 experienced stronger price appreciation over the decade compared to condos in the same districts.
- This comparative trend reflects underlying market fundamentals: landed homes are more limited in supply and remain highly sought after in these core central areas.
