How to know if an Idealista price is inflated

A portal price is an expectation, not a value. It is cross-checked against the closing price/sqm of the area (Registradores, municipal appraised value), the median of comparable listings and the time it has been published.

How it works

Asking vs closing; time on market and price drops; duplicate listings from multiple agencies; how to calculate deviation from the median; why the average is misleading.

How Nexus does it

Compares the asking price with the calculated band and shows the divergence in percentage; comparables are filtered for consistency and deduplicated.
