One notice can cover many buildings — count notices, never building rows, or a single multi-unit scheme reads as a trend (T11).

€250,000 – €1,525,000, 15 Nov 2023 to 17 Dec 2025.

PPR addresses are geocoded, not surveyed — a sale's position is as good as its address match (`rooftop_n` says how many are address-accurate). Beds, floor area, BER and asking price come from the matched daft.ie advertisement, not from the Register, and only where a match was found (`enriched_n`).
