Initial rent, stressed areas & reference index 2 min read · published September 11, 2025
If you are a tenant in Spain and you are going to sign or renew a contract in a tension area, it is normal to have doubts about the initial amount, rent increases and the use of the reference index. This guide explains clearly what legal limits exist, how the index is calculated and applied, which clauses to review in the contract and what steps to take if you believe you are being overcharged or your rights are being violated. It also indicates how to document communications, when to make claims before the homeowners' community or in court and where to seek official help. The information here is practical and aimed at helping you make informed decisions.

What you should know

In tension areas there are specific rules that protect the tenant regarding increases and contract conditions. The Urban Leases Act and its application determine limits and obligations. The reference index for updates can set caps or guidelines and is consulted in the corresponding regulation[1]. Before signing, review clauses about duration, deposit and possible rent updates.

Always check rent update clauses before signing.

How the index is applied

The landlord may only apply increases if the contract provides for them and if the increase complies with the index and the law. If you receive a proposed increase, request the calculation in writing and keep the communication. If there are doubts, seek advice and do not pay extra amounts without proof.

  • Check deadlines and dates to accept changes.
  • Verify the initial amount and the update method.
  • Report habitability issues in writing and request repairs.
  • Keep photos, receipts and messages as evidence.
Respond to notifications within deadlines to avoid losing rights.
