For older landed properties (e.g., built in the 1960s-1970s), documents may not have been passed down—contact BCA directly if the online search yields no results, as CSC is essential for transactions and bank financing. EdgeProp Singapore's landed property directory can help identify details for properties like those in Serangoon Gardens or Bukit Timah estates.
Thank you for reaching out to EdgeProp Buddy. For detailed insights, it's always a good idea to consult with a real estate professional on topics like this.
