The record

How many HDB resale flats were registered on Upp Serangoon View in September 2026?

September 2026.

Ledger rows with keys from sg:hdb: whose street, the third part of the key, is UPP SERANGOON VIEW, in any town, whose attribute is resale_price_sgd, and whose observed month is 2026-09. Each registration seals one such row, so this counts registrations, not re-reads.

Against the last month

The two figures are the same. Both figures come from the same read, asked of each window.
