## Tools (5)

- `compare_places`: Side-by-side latest figures for 2–4 municipalities (provinces of Alicante, Málaga, Valencia, Murcia) or buyer zones: housing prices (MIVAU), rent (SERPAVI), IBI, population, income, tourist lets, foreigners, air quality and more — at most 12 indicators per call. Each figure has its unit, period, level (municipality, or province when the place has none), source credit and date, and station or point of interest with distance. Only places whose flatin.es page is published get figures; every answer links the flatin.es pages.
- `ibi_rate`: Yearly IBI urbana rate (% of cadastral value) of a municipality, with year, provisional flag, source (Ministerio de Hacienda) and the flatin.es page.
- `newbuilds_in_place`: New-build developments on sale in a municipality, buyer zone or province of the flatin.es catalogue: at most 25 per call, sorted by name, no pagination — the full list is on the linked flatin.es page. Facts are the developer's own, latest check only, with attribution.
- `non_resident_tax`: Yearly IRNR of a non-resident owner of a Spanish home: imputed income (1.1 % or 2 % of the cadastral value for days not let) and rental income (EU/EEA: 19 % net of expenses; others: 24 % on gross rent). Every line cites its law and check date; rules pending validation (RDL 29/2026) are listed, not applied. An estimate, not tax advice.
- `purchase_costs`: Taxes and fees of buying a home in Spain: VAT + stamp duty (AJD) for a new build or transfer tax (ITP) for a resale at the general rate of the tax territory, plus notary and land registry by the official scales. Every line cites its law, article and the date it was checked. An estimate, not tax advice.
