━━ How it works
From Rightmove link to investor-ready in under a minute.
No data entry. No category dropdowns. Paste, wait four seconds, read the verdict.
Paste the URL
DataDeal pulls the listing's PAGE_MODEL — price, postcode, bedrooms, tenure, square metres, lease length — and geocodes it via postcodes.io + Nominatim.
The engine runs
SDLT (2026 rates), regional refurb (ONS Q1 2026 NUTS1 × 5 trades), and all six strategies — buy-to-let through PLO — fire in parallel. PRA stress-test included.
Verdict in JetBrains Mono
Best-by-goal rankings (cashflow / yield / ROI / capital growth / low-cash-in). Min-viable pass/fail. Warnings tiered by severity. One click to save.
━━ Where the numbers come from
Authoritative UK data, not LLM hallucinations.
Every figure we surface traces back to a named public dataset. If we can't source it, we don't show it — we flag it as a warning.
