Introduction
Leasing residential or commercial property in Turkey is governed strictly by the Turkish Code of Obligations (Türk Borçlar Kanunu, Law No. 6098). The legal framework balances landlord property rights with robust protections for tenants. For foreign property owners leasing out real estate or expatriates renting homes in Turkey, understanding statutory rent increase caps, mandatory mediation protocols, and lawful eviction grounds is essential to avoiding costly court disputes.
1. Statutory Rent Increase Calculation in Turkey
Under Article 344 of the Turkish Code of Obligations, annual rent increases for residential and commercial leases are strictly capped by law:
- CPI Rate Indexation (TÜFE): The maximum lawful rent increase rate is determined by the 12-month average change in the Consumer Price Index (TÜFE), published monthly by the Turkish Statistical Institute (TÜİK). Landlords cannot contractually enforce a rent increase higher than this statutory rate.
- The 5-Year Rent Determination Law (Kira Tespit Davası): After a lease agreement has been renewed continuously for 5 years, either the landlord or the tenant has the legal right to file a Rent Determination Lawsuit (Kira Tespit Davası). The court reviews prevailing market rents, comparative local values, and inflation metrics to adjust the rent to fair market rate, regardless of previous annual statutory caps.
2. Legal Grounds for Evicting a Tenant in Turkey
Turkish landlord-tenant law heavily favors tenant security of tenure. A fixed-term lease agreement does not automatically terminate at the end of the term; it automatically renews on a yearly basis unless the tenant gives a written non-renewal notice at least 15 days before the expiry date.
Landlords can evict tenants only under specific statutory conditions outlined in the law:
- Eviction Commitment Letter (Tahliye Taahhüdü): A written commitment signed by the tenant promising to vacate the property on a specific date. To be legally enforceable, the Tahliye Taahhüdü must be signed after the lease start date and delivery of the property key.
- Necessity for Personal or Family Housing (Gereksinim Nedeniyle Tahliye): A landlord can file an eviction lawsuit if they, their spouse, descendants, ascendants, or dependents genuinely require the property for primary residence or workplace needs.
- Non-Payment of Rent (Two Just Warnings): If a tenant fails to pay rent twice within a single lease year, the landlord can send two formal notary notices (İhtarname) and initiate eviction proceedings.
- Reconstruction or Substantial Renovation: If the building requires major structural redevelopment or renovation making it uninhabitable, eviction can be requested.
- 10-Year Extension Period Rule: After a lease has extended for 10 continuous years beyond its initial term, the landlord may terminate the lease without stating specific cause by serving a 3-month advance notice prior to the end of the extension year.
3. Mandatory Mediation in Turkish Tenancy Disputes
In an effort to resolve landlord-tenant conflicts efficiently and relieve court caseloads, Turkey introduced Mandatory Legal Mediation (Dava Şartı Arabuluculuk) for tenancy disputes.
Before filing any lawsuit regarding rent determination, eviction, or unpaid rent claims in court, parties must apply to an official mediator. If an agreement is reached during mediation, the resulting signed accord carries the legal weight of a court judgment, preventing lengthier litigation.

Frequently Asked Questions (FAQ)
Q1: Is an Eviction Commitment Letter (Tahliye Taahhüdü) signed on the same day as the lease valid?
A: No. Turkish courts consistently rule that eviction commitment letters signed concurrently with the lease agreement are invalid because the tenant is presumed to be under duress. The commitment must be executed on a date subsequent to the signing of the lease and physical property delivery.
Q2: How much can a landlord increase the rent in Turkey?
A: Rent increases are capped at the 12-month average Consumer Price Index (TÜFE) rate published by TÜİK at the time of renewal. Landlords cannot unilaterally charge higher rates unless the lease has reached its 5th anniversary and a court orders a rent recalculation.
Q3: Can a landlord evict a tenant simply because they sold the property?
A: The new owner steps into the previous landlord’s legal shoes. The new owner can demand eviction only if they have a genuine personal need for the property, provided they notify the tenant in writing through a notary within 1 month of purchasing the property and give the tenant 6 months to vacate.
Q4: Do landlords and tenants have to go to mediation before going to court in Turkey?
A: Yes. Mandatory legal mediation is a legal prerequisite for tenancy lawsuits in Turkey. Failing to complete the mediation process results in the immediate procedural dismissal of court applications.
