Casalupa — Honest Property Verdicts

Casalupa gives you an honest, 60-second second opinion on any home listing you're viewing on Idealista, Fotocasa, or Habitaclia. Open a listing, click the Casalupa button, and get: • A price verdict — is the asking price fair, over, or under, based on real nearby sales? • Building facts from the official Cadastre (year built, size, units). • Sun hours, street noise, walkability, and nearest transit. • Red flags and the exact questions to ask before you visit. Rental listings are recognized too — Casalupa shows the relevant analysis for rentals (a fair-rent check is coming soon). Why trust it? Casalupa is 100% buyer-side. We are never paid by agencies or portals — our only job is to protect the person buying or renting the home. Private by design: we only read the listing page you open. No account needed to try. No ads, no tracking, no selling of your data.
