Repossessions are a provincial figure (INE) and turnover is municipal (MIVAU). They measure the market's risk and how easily it resells, not the quality of this particular property.

Without enough municipal coverage the factor stays at 50, neutral: it neither rewards nor penalises.

In most court auctions the charges ranking ahead of the executing creditor are not extinguished: the successful bidder takes them on. Possession is not guaranteed and may require eviction proceedings at the buyer's cost. Bidding requires a digital certificate, DNIe or Cl@ve and posting the stated deposit in advance. Always check the full terms in the official BOE notice.

Medium confidence: coverage is reasonable, with some relevant details to confirm.

Confidence measures how much data we hold, not the quality of the investment. We publish no arrears estimates: income, employment and crime figures are market context, never an indicator of tenant risk.
