Local Comparable Rent: Tenant Mistakes in Austria

Rent & increases (reference rent, categories, form) 2 min read · published September 10, 2025

Many tenants in Austria face decisions when the landlord adjusts or establishes rent based on the local comparable rent. Common mistakes occur because evidence is missing, deadlines are missed, or formal requirements are ignored. In this article we explain in plain language what the local comparable rent means, which documents help you as a tenant and how to respect deadlines and formal obligations. We provide practical steps to prepare an objection, check comparable rents and collect evidence. The aim is that you, as a tenant in Austria, can respond more confidently and avoid typical mistakes without needing legal expertise. Keep the Mietrechtsgesetz in mind.[1]

Collect all rent receipts and correspondence early.

What tenants should often watch for

The main sources of mistakes are easy to overlook: wrong selection of comparable apartments, missing or incomplete documentation, failure to meet formal requirements for increases, and missed objection deadlines. Some landlords rely on comparison rents that are not comparable (e.g. different amenities or heating). Always check the basis of the comparison and request proof if necessary.[2]

  • Collect documents: leases, heating bills and receipts.
  • Meet deadlines: observe objection and response periods in time.
  • Check formal requirements: watch for written form requirements when increases occur.
  • Document apartment condition: record defects and repairs.
Thorough documentation increases your chances in disputes.

Concrete mistake examples

Typical avoidable mistakes include applying the rent index incorrectly, not asking for comparable apartments, or not saving digital messages. If you receive documents electronically, save copies in a secure folder. Respond to formal letters from the landlord in writing and keep proof of sending.

Errors with comparable apartments

Comparable apartments must be similar in location, features and size. Pay attention to differences in heating type, area and construction year because these factors significantly affect the local comparable rent.

Avoid formal errors

Some rent adjustments require a specific form. When a landlord asserts an increase, check whether the statement is in writing and comprehensible. If the form is missing, you may be able to contest it.[3]

Always respond to notices in writing rather than only verbally.
