🎉 Sold Prices Forensics — Launch!
Cross-Border Sold Prices in One CSV — pull historical sold-price comparables from Zillow (US), Rightmove (UK) and Zoopla (UK) in a single normalized dataset. The only multi-platform sold-prices actor on the Apify Store.
Per-Address Forensic Lookup — byAddress mode returns the full sale history for a US or UK subject property, the dataset RICS surveyors and US appraisers build manually in a day.
UK Area Sweep for Comps — byArea mode sweeps a UK neighbourhood, town or postcode (Hampstead, SW1A, Manchester) across Rightmove and Zoopla for comparable-sales evidence.
Repeat-Sale Rows Preserved — properties with multiple historical sales emit one row per sale event, keyed by sourceId + saleDate — Case-Shiller-style repeat-sale analysis works out of the box.
Currency Declared Per Row — every row tags currency (USD / GBP) and country (us / uk). No silent FX, no guessing — cross-border investors own the conversion step.
Normalized 20-Field Schema — identical column shape across Zillow, Rightmove and Zoopla rows. No per-source parsers, no schema reconciliation.
Year-Range Filter — yearFrom / yearTo bound the sale-year window cleanly across all three platforms in one filter.
Auto-Pagination on UK Area Sweeps — drains Rightmove and Zoopla area feeds until exhausted, respecting maxResults and the FREE-tier safety net.
Cross-Platform Disambiguation — the sourcePlatform column lets you filter to one source (e.g. Zoopla only) or keep cross-source rows for validation.

🗺 Honest v1.0 Scope (Not Roadmap Vapor)
This v1.0 ships the three platforms where the upstream data path is forensics-grade and reliable:
Zillow (US per-address sale history)
Rightmove (UK area comparable-sales)
Zoopla (UK per-address forensic + UK area comparable-sales)
Two platforms were deliberately dropped from v1.0 rather than shipped half-broken:
Redfin — the historical sold-prices data path returns redacted prices through this feed (the numeric price is replaced with a redaction marker), which makes the data unusable for valuation work. On the v1.1 backlog if the redaction lifts.
Idealista (Spain / Italy / Portugal) — no unit-level historical-transactions endpoint exists; Spanish/Italian/Portuguese public records do not publish per-property sold prices through Idealista's data path. On the v1.1 backlog if a historical endpoint becomes available.
We chose to ship the honest version: three reliable platforms with one normalized schema, instead of a four- or five-platform actor where some sources silently degrade your downstream pipeline.
🔭 v1.1 Backlog
Redfin coverage — when the upstream restores numeric sold prices.
Idealista coverage (ES / IT / PT) — when a historical-transactions endpoint becomes available.
Listing-price history — Zoopla's parallel "asking price over time" series, kept separate from transaction prices.
