Check Spain's Rent Reference Index for Tenants

Initial rent, stressed areas & reference index 2 min read · published September 11, 2025

If you are a tenant in Spain and are concerned about initial rent or high-pressure zones, knowing how to check the MITMA reference index helps you understand limits and price comparisons. This practical guide explains step by step how to find the official index, interpret its figures and what they mean for your lease agreement. It also states when the law and courts may intervene, what evidence to collect and how to file complaints if you detect a discrepancy. The text avoids jargon: you will find clear examples, documents to consult and the deadlines you must respect to protect your rights as a tenant in Spain.

What is the reference index?

The reference index published by MITMA provides statistical series by area and period that serve to compare market prices and guide the initial rent. It does not replace legislation, but it helps detect significant deviations compared to comparable leases. The Urban Leases Act regulates aspects of the rental market and may be relevant in disputes about initial rent.[1]

In most regions, tenants are entitled to basic habitability standards.

How to check the index step by step

  1. Access the official MITMA portal and look for the rental price index section.
  2. Select the province or municipality and the time period you need.
  3. Download the table or report and keep a copy for your records.
  4. Compare the figure with your contract price and note any relevant differences.
  5. If you find a deviation, gather comparable documents: ads, contracts and receipts.
Save screenshots and PDFs of the index with the date as evidence.

Interpreting figures and limits

The index offers mean values and percentiles; a mean does not mean every dwelling must match it exactly. In pressured zones, regional rules and measures may impose additional limits on initial rent and updates, and sometimes criteria apply for contract review.

Documenting the local market strengthens any claim against the landlord or in court.

Frequently Asked Questions

Does the index force rents to be lowered?
No. The index is advisory; the obligation to modify a rent only arises if a specific rule or a court decision requires it.
Can I use the index to challenge an excessive rent?
Yes: as a tenant you can submit the index and comparable evidence in a claim to the landlord or in a civil court, following applicable procedural deadlines.[2]
Where can I consult the law that governs rental contracts?
The Urban Leases Act in the BOE contains the basic rules on contracts and rent updates.[1]

How-To

  1. Locate the index on the official portal and download the version for your area.
  2. Gather comparable contracts and listings and prepare a document with tables and screenshots.
  3. Send a formal request to the landlord asking for explanation or adjustment, and keep a copy of the submission.
  4. If there is no response, consider filing a claim in the Court of First Instance providing all documentation.
