Chapter overview
You just got a viewing. Every hour now counts. Landlords in Munich, Berlin, or Hamburg review 40 to 80 applications over a single weekend. Whoever delivers a complete, verified folder at first contact wins. Whoever asks whether they can send documents later lands on the rejection pile.
Key takeaways
- Have your folder ready before the viewing, not after.
- Every document answers a specific question the landlord has: Who are you? Can you pay? Are you reliable?
- Redact your account number and tax deductions in payslips, but leave gross and net income visible.
- A fresh CRIF report (max. 3 months old) beats any old printed document.
- Verified documents via rentcard eliminate any suspicion of tampering, which unverified PDFs cannot.
The 8 documents and what the landlord checks with each
Every document in your folder answers a specific question. Once you understand which question that is, you also know why it is non-negotiable and how to prepare it.
1. Passport or national ID
Landlord's question: Who exactly is this person?
A copy or verified ID check. Must be currently valid. Never submit an expired document.
2. Payslips (last 2–3 months)
Landlord's question: Can this person consistently pay the rent?
Gross and net income must be visible. Redact the account number and tax deductions. Rule of thumb: net income should be at least three times the base rent.
3. CRIF credit report
Landlord's question: Does this person have outstanding debts or negative entries?
Maximum 3 months old. Older printouts look stale and raise suspicion. A CRIF report via rentcard is directly verified, which removes any question of tampering before it can arise.
4. Tenant self-disclosure form (Mieterselbstauskunft)
Landlord's question: How many people are moving in, are there pets, are there ongoing debts?
Not legally required but factually standard across Germany. Providing false information entitles the landlord to immediate termination under § 569 BGB. Always fill out completely and sign.
5. Employment contract or confirmation letter
Landlord's question: Is the income permanent or temporary?
Permanent contracts are ideal. Do not hide fixed-term contracts, but include any renewal letter if available.
6. Rent-free certificate (Mietschuldenfreiheitsbescheinigung)
Landlord's question: Did this person pay on time with their last landlord?
The single most effective trust document in the folder. Many landlords ask for it specifically. If your previous landlord has no standard form, a simple written statement is sufficient. More detail in the guide on Mietschuldenfreiheitsbescheinigung.
7. Income proof for self-employed applicants
Landlord's question: Is the income stable or volatile?
Last tax assessment, current BWA (profit and loss summary), and 3 bank statements. The more consistent the figures, the better. See the Einkommensnachweis guide for details.
8. Guarantor declaration (optional)
Landlord's question: Who is liable if this person cannot pay?
Relevant for apprentices, students, or career starters. A parent or relative guarantees payment in writing. Without a guarantor, applicants with insufficient income have little chance in competitive markets.
Must-have vs. nice-to-have: what is required and what helps?
Not all documents carry equal weight. The must-haves are the minimum without which no application gets serious consideration. The nice-to-haves are extras that tip the scales when the race is close.
Must-have (non-negotiable)
- Passport or national ID
- Payslips (2–3 months)
- CRIF credit report (max. 3 months old)
- Tenant self-disclosure form (filled and signed)
Nice-to-have (sets you apart)
- Rent-free certificate from previous landlord
- Employment contract or confirmation
- Personal cover letter (5–7 sentences)
- Guarantor declaration (apprentices, students)
- Proof of savings (if income is on the low side)
Legal note: what landlords cannot ask for
Preparing documents correctly and legally
An application folder contains sensitive data. What you redact, which version you submit, and how current your report is will determine whether you come across as professional or raise suspicion.
What to redact in your payslip
You are not required to submit your payslip unredacted. The following fields you may and should cover:
- Account number (IBAN): Always redact. No landlord needs your bank account number.
- Detailed tax deductions: May be redacted. Net amount and gross amount must remain readable.
- Employer social security contributions: Optional, not required by the landlord.
- Remaining holiday balance: Not relevant for creditworthiness, may be redacted.
Why a fresh CRIF report is decisive
Many applicants submit a credit report they printed a year ago. This looks unprofessional and is practically worthless because the landlord has no way of knowing whether anything has changed since. A CRIF report retrieved and verified directly through rentcard is current to the day and shows the landlord exactly what they want to see: a confirmation that your creditworthiness is in good standing right now.
Request your report at least two weeks before you start actively searching. CRIF offers a free data copy under GDPR Article 15, but processing takes up to four weeks. Those who need it fast should use the paid instant option or the integrated retrieval through rentcard.

Why digital folders beat paper every time
A landlord with 40 applications for a Munich apartment does not review them all at the same time. They open what arrives first and is easiest to access. Sending an email with a clear link, delivering a structured digital folder, wins the first five seconds. Sending a zip attachment with 14 PDFs loses them.
PDF attachment by email
- Landlord must open each file separately
- No protection against document manipulation
- Cannot be updated after sending
- Sensitive data sits uncontrolled in unknown inboxes
- ZIP attachments are often flagged as spam
Digital folder with rentcard
- One link, everything organised and instantly accessible
- Documents are verified and tamper-proof
- Updatable at any time without resending
- Access revocable per landlord individually
- Landlord can see when they opened the folder
The decisive difference from simply emailing PDFs is verification. An unknown applicant sends a payslip PDF. How does the landlord know the figures have not been altered? With rentcard, every document is verified by an independent source. The landlord does not have to wonder.
Timing: have your folder ready before the viewing
The most common mistake: the folder is assembled only after the viewing. By then, valuable time is lost. A landlord with 30 applications on the table will not wait for you. Being able to share the folder link right after the viewing, or even during the conversation, makes the strongest possible impression.
Your preparation plan: 2 weeks before the first viewing
- Week 1: Request your CRIF report (instant option or via rentcard).
- Week 1: Gather payslips from the last 3 months and redact account numbers.
- Week 1: Fill out and sign the tenant self-disclosure form.
- Week 2: Check your ID (still valid?), renew if needed.
- Week 2: Request a rent-free certificate from your previous landlord.
- Week 2: Upload all documents to rentcard and finalise your folder.
- Day of viewing: have the folder link ready, share it right after the conversation.
Those searching in Munich or other highly competitive markets who want more strategy will find concrete measures in the Wohnungssuche-Tipps guide. The folder is the decisive final step.
With rentcard: verified, not just uploaded
The difference between a rentcard folder and a collection of self-uploaded PDFs lies in verification. rentcard checks your identity through an official ID match, verifies income directly via your bank through Open Banking, and integrates the CRIF report live. The landlord sees clearly: these figures were not assembled by the applicant themselves and could have been altered. They are verified.

Frequently asked questions
Answers to the most common questions about apartment hunting in Germany.
Which documents do I need for a rental application in Germany?
The must-haves are: passport or national ID, payslips from the last 2 to 3 months, a current CRIF credit report (maximum 3 months old), and a completed tenant self-disclosure form. A rent-free certificate from your previous landlord and an employment contract significantly strengthen your application.
What can I redact in my payslip?
Your account number (IBAN) should always be redacted. Detailed tax deductions can also be covered. However, gross income and net income must remain legible, as the landlord uses them to verify that your income is at least three times the base rent.
When should I have my application folder ready?
Ideally two weeks before you start scheduling viewings. The free CRIF report takes up to four weeks. Assembling your folder only after a viewing means losing out to applicants who can share their link immediately after the conversation.
What is the difference between a verified folder and emailing PDF attachments?
With PDF attachments, the landlord has no way of knowing whether figures have been altered. A verified folder via rentcard proves that identity, income, and the credit report were checked by independent sources. This eliminates any suspicion of tampering and builds trust before a personal conversation even takes place.
