The record

How many HDB resale flats were registered on Bt Batok St 21 in October 2026?

October 2026.

Ledger rows with keys from sg:hdb: whose street, the third part of the key, is BT BATOK ST 21, in any town, whose attribute is resale_price_sgd, and whose observed month is 2026-10. Each registration seals one such row, so this counts registrations, not re-reads.

The month is still open, so this figure can still grow.

Against the last month

A difference of -7 against 2026-09. Both figures come from the same read, asked of each window.
