סרנגון

Serangoon is treated as a Singapore micro-area anchored to the URA Serangoon planning area or subzone and the D19 postal district. For CASABROVA it functions as a residential investment comparison unit rather than a separate municipality: liquidity, tenure mix, public-transport access and HDB/private housing depth should be assessed inside the wider Districts 19-21 bucket. The seed keeps STR flagged as banned because normal residential accommodation cannot be let for tourist-style short stays.
