Tenant-screening documentation: select on relevant evidence rather than personal impressions
Tenant screening can reduce payment and communication risk, but it does not mean collecting as much information as possible about an applicant’s private life. In Türkiye, personal-data processing is subject to KVKK principles including lawfulness, specified purpose, relevance, proportionality and limited retention. A sound screening process should therefore be simple and consistent, focusing on identity, realistic ability to carry the rent, stability of income and verifiable contractual behaviour.
Set written criteria before applications arrive
Define reasonable requirements in advance, such as an affordability threshold, acceptable income evidence, maximum lawful occupancy, intended lease start date, guarantor requirements where appropriate and clearly stated property policies. Predefined criteria reduce arbitrary decisions and make it easier to compare applicants on the same basis instead of changing the standard according to who is applying.
Verify identity only to the extent required
Use appropriate identity evidence to confirm the person’s legal name and the identity or passport data needed for the tenancy. Do not automatically retain unnecessary copies when the purpose can be achieved by recording verified information securely. Where a copy is genuinely needed for contractual or legal reasons, store it with restricted access rather than circulating it among unrelated brokers.
Assess income using the appropriate evidence
A salaried applicant can support income with payroll, employment documents or account records; a self-employed person may need a different combination. There is no single perfect document. Look for consistency between declared income, supporting evidence and the ability to cover rent, deposit and recurring costs. A high but volatile income can require more liquidity than a lower but highly stable salary.
Review continuity of employment or income source
Time in the current role, contract type, regularity of payments and continuity of business can help explain risk. Do not contact employers or third parties casually without an appropriate basis and the applicant’s knowledge where required. A newly employed tenant can sometimes compensate for limited history with demonstrable savings, a suitable guarantor or another lawful risk-control arrangement.
Use verifiable rental references
With an appropriate basis, a prior landlord can be asked about tenancy duration, payment regularity and property handover. Do not treat a telephone number supplied by the applicant as automatically reliable where the decision is material. Cross-check the reference against a prior lease, address or other consistent information. The objective is to verify basic contractual conduct, not collect gossip.
Separate financial suitability from personal judgement
Appearance, nationality or conversational style does not establish ability to pay. Use indicators linked to the tenancy: income, obligations, documented payment history, expected duration and lawful occupancy considerations. An objective framework improves decision quality and reduces the risk of unjustified discrimination or rejection of a good applicant on the basis of intuition.
Avoid sensitive and unnecessary data
Do not request medical, political, religious or unrelated family information that is unnecessary for establishing and operating the lease. KVKK principles require data processing to be connected to a legitimate purpose and limited and proportionate. Even ordinary personal information should not become a broad private profile simply because a landlord has the ability to ask for it.
Document the decision in a short scorecard
Record that identity was verified, the income source, rent-to-income relationship, employment history, rental reference, guarantor if any and material agreed conditions. Avoid insulting, speculative or subjective notes. If an applicant is declined, the internal reason should be tied to objective criteria such as insufficient documented income or inability to verify identity rather than personal characteristics.
Protect applicant files
Rental applications can contain bank statements, salary information and identity documents. Store them in a protected location rather than a group chat or shared public device. Where a broker collects information, responsibilities for transfer, access and deletion should be clear. Applicant information should not be reused for unrelated marketing or passed to other landlords without a proper basis.
Set a retention and deletion policy
For the chosen tenant, retain what is necessary for the lease, rights and legal obligations for the appropriate period. Files of unsuccessful applicants should not be kept indefinitely simply because they may be useful someday. Establish a justified retention period and delete or securely destroy information when its legal or operational purpose has ended.
Do not let screening replace a good lease process
Even an excellent applicant can later experience financial difficulty. Screening does not replace a clear lease, properly documented deposit, move-in inventory, traceable payment channel and condition report. Screening reduces uncertainty at the beginning; disciplined recordkeeping and communication manage risk throughout the tenancy.
Update the process as the market and law change
Evidence suitable for a local salaried worker may differ from that of a remote employee, entrepreneur or foreign resident. Adapt the form of evidence without abandoning consistency or fairness. Review data practices and tenancy documents as KVKK and rental rules evolve. A strong process gathers enough information for a responsible financial decision without turning a rental application into a disproportionate investigation of the applicant’s life.
