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

Sales 93 in 36 months within 500 m

€10,000 – €56,035,242, 20 Sept 2023 to 1 Sept 2026.

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`).
