Apartment Deposit Loan Germany: How to Finance Your Mietkaution in 2026
In Germany, the rental deposit (Mietkaution) can be up to 3 months’ cold rent — that’s €2,400–€5,400 in cities like Berlin or Munich. For foreigners arriving without German savings, this is often the biggest financial hurdle before your first salary arrives. The good news: you have legal rights and real financing options most landlords won’t tell you about.
How Much Is the Rental Deposit in Germany? (2026 Numbers)
Average Deposit Amounts by City
| City | Avg. 1-BR Cold Rent | Typical Deposit (3x) |
|---|---|---|
| Munich | €1,400–€1,800 | €4,200–€5,400 |
| Frankfurt | €1,000–€1,400 | €3,000–€4,200 |
| Hamburg | €950–€1,300 | €2,850–€3,900 |
| Berlin | €900–€1,300 | €2,700–€3,900 |
| Cologne | €800–€1,100 | €2,400–€3,300 |
| Smaller cities | €500–€800 | €1,500–€2,400 |
What the Law Says: §551 BGB Explained Simply
German law (§551 Bürgerliches Gesetzbuch) sets clear rules:
- Maximum deposit: 3 times the monthly cold rent (Nettokaltmiete) — no landlord can legally charge more
- Separate account: Your landlord must hold the deposit in a separate, insolvency-protected savings account
- Interest belongs to you: Any interest earned on the deposit is legally yours
- Any contract clause exceeding these limits is void — even if you already signed it
The Secret Most Foreigners Don’t Know: You Can Pay in 3 Installments
Under §551 Abs. 2 BGB, you have an absolute legal right to pay the deposit in 3 equal monthly installments. Your landlord cannot refuse this. This is law, not a favor.
How it works for a €2,400 deposit:
- Move-in day: Pay €800 (first installment)
- Month 2: Pay €800 with your rent
- Month 3: Pay €800 with your rent
This costs you nothing extra — no interest, no fees, no credit check. Simply inform your landlord in writing: “Gemäß §551 Abs. 2 BGB möchte ich die Mietkaution in drei gleichen monatlichen Teilzahlungen entrichten.”
Important: If you fall behind on installments by an amount equal to 2x your cold rent, the landlord may have grounds for termination. Always pay on time.
4 Options When You Can’t Pay the Full Deposit Upfront
Option 1: Personal Loan (Ratenkredit)
Borrow €1,000–€5,000, pay the deposit in cash, repay monthly. The deposit is legally yours and earns interest in the landlord’s account.
| Your SCHUFA | Typical APR | Monthly Payment (€2,400 / 24 months) |
|---|---|---|
| Good | 3–6% | ~€103–€107 |
| Average | 6–9% | ~€107–€110 |
| Bad / No SCHUFA | 10–15% | ~€112–€118 |
You can compare instant loan offers as a foreigner using SCHUFA-neutral comparison tools. For amounts under €3,000, check small loan options starting from €500. If your SCHUFA is an issue, read our guide on getting a loan with bad SCHUFA.
Option 2: Mietkautionsbürgschaft (Deposit Guarantee)
Instead of cash, an insurance company provides a guarantee certificate to your landlord. You pay an annual premium — typically 3.9–5.5% of the deposit amount.
| Deposit Amount | Annual Cost (3.9%) | Annual Cost (5.5%) |
|---|---|---|
| €1,500 | €58/yr | €82/yr |
| €2,400 | €94/yr | €132/yr |
| €3,600 | €140/yr | €198/yr |
Caveat for foreigners: All Bürgschaft providers require a credit check (SCHUFA or Infoscore). New arrivals with no German credit history are often rejected. Consider the installment option (§551) or a personal loan first.
Caveat for everyone: Landlords are not legally required to accept Bürgschaft insurance. In tight markets (Berlin, Munich), many refuse. Always confirm with your landlord before applying.
Option 3: Employer Advance (Arbeitgeberdarlehen)
Some German employers — especially larger companies hiring international talent — offer deposit assistance as part of relocation packages. Ask your HR department. These loans are usually interest-free or very low interest.
Option 4: Family Loan (Privatdarlehensvertrag)
Borrow from family or friends. Use a written Privatdarlehensvertrag (private loan agreement) documenting: amount, repayment schedule, interest (can be 0%), and signatures. For international transfers, use Wise for the best exchange rates (0.3–1.5% fee vs. €25–40 SWIFT fees).
Loan vs. Bürgschaft: Which Costs Less?
For a €2,400 deposit — the real numbers over time:
| Year | Bürgschaft (3.9%/yr) | Loan (7% APR, 36 months) |
|---|---|---|
| Year 1 | €94 | €290 total interest (paid over 3 years) |
| Year 2 | €188 | (loan still being repaid) |
| Year 3 | €282 | €290 (loan fully paid off) |
| Year 4 | €376 | €290 (no more costs) |
| Year 5 | €470 | €290 (still no more costs) |
Rule of thumb:
- Staying less than 3 years? Bürgschaft is cheaper.
- Staying more than 4 years? A loan saves money — and the deposit earns interest for you.
- Can’t get either? Use the legal installment right (§551) first.
What You Need as a Foreigner
For a deposit loan application:
- Valid passport + residence permit (Aufenthaltserlaubnis)
- German address registration (Meldebescheinigung)
- German bank account (IBAN required)
- Employment contract or last 3 months payslips
- Loan term cannot exceed your remaining permit validity
Timeline: Online lenders typically transfer funds within 24–48 hours after VideoIdent verification. Some offer same-day payout via SEPA Instant.
Getting Your Deposit Back
When you move out:
- Standard return timeline: 3–6 months (courts consistently rule this is “reasonable”)
- Maximum if utility bill pending: Up to 12 months (for Nebenkostenabrechnung)
- With interest: Landlord must return accrued interest too
- If sold: New owner inherits deposit liability (§566a BGB) — even if previous landlord never passed it on
Landlord won’t return it? Send a written demand (Mahnung) by registered post with a 14-day deadline. If no response, contact your local Mieterverein (tenant protection association, ~€50–100/year membership) or file directly at Amtsgericht — no lawyer needed for claims up to €5,000.
Watch Out: Deposit Scams Targeting Foreigners
- Never pay before viewing: Fake listings ask for deposit transfers before you see the apartment. Always visit in person first.
- Never pay cash: Always pay by bank transfer (Überweisung) with reference “Mietkaution [address]” for proof.
- Refuse if landlord demands more than 3x cold rent: It’s illegal under §551 BGB — even if written in the contract.
- Beware of “Ablöse” + Kaution combos: Landlords sometimes charge for furniture (Ablöse) on top of the deposit, pushing total upfront costs above the legal limit.
Key Takeaways
- Legal right to pay in 3 installments (§551 BGB) — free, no credit check, landlord cannot refuse
- Maximum deposit is 3x cold rent — anything above is void
- Personal loan costs ~€290 in total interest for €2,400 — cheaper than Bürgschaft after year 3–4
- Bürgschaft costs ~€94–132/year — better for short stays under 3 years
- Never pay deposit in cash or before viewing the apartment
- Deposit must be returned with interest — usually within 3–6 months after move-out
FAQ
How much is the rental deposit (Mietkaution) in Germany in 2026?
The maximum deposit is 3 times the monthly net cold rent (Nettokaltmiete) under §551 BGB. In practice: Berlin €2,700–€3,900, Munich €4,200–€5,400, Hamburg €2,850–€3,900, Frankfurt €3,000–€4,200. Smaller cities typically €1,500–€2,400.
Can I pay the rental deposit in installments in Germany?
Yes. Under §551 Abs. 2 BGB, you have a legal right to pay in three equal monthly installments. First installment is due at tenancy start, with the second and third due alongside your next two monthly rent payments. Your landlord cannot legally refuse this.
What is Mietkautionsbürgschaft and how does it work?
A Mietkautionsbürgschaft is a guarantee certificate from an insurance company given to your landlord instead of a cash deposit. You pay an annual premium of 3.9–5.5% of the deposit amount — approximately €94–€132 per year for a €2,400 deposit. However, landlords are not required to accept it, and all providers require a credit check.
Can foreigners get a loan for a rental deposit in Germany?
Yes. Most online lenders offer personal loans of €1,000–€5,000 for any purpose, including rental deposits. You need a valid residence permit, German bank account, and proof of regular income. EU/EEA citizens and Blue Card holders have the highest approval rates. Funds typically arrive within 24–48 hours.
How fast can I get a deposit loan in Germany?
With a fully digital application, you can receive pre-approval within minutes. After VideoIdent verification, funds are typically transferred within 24–48 hours. Some banks offer same-day payout via SEPA Instant if you apply before 2 PM on a business day.
Is Mietkautionsversicherung (deposit insurance) worth it?
It depends on how long you stay. At ~€94–132 per year, it is cheaper than a loan for stays under 3 years. But over 4–5 years, you would pay €376–€660 in premiums with nothing to show for it. A personal loan with ~€290 total interest is cheaper long-term because you own the deposit and it earns interest.
How long does a landlord have to return my deposit?
There is no fixed legal deadline. Courts consistently rule that 3 to 6 months is reasonable. If the annual utility bill (Nebenkostenabrechnung) is still pending, landlords may hold a portion for up to 12 months. The deposit must be returned with all accrued interest.
Does taking a deposit loan affect my Schufa score?
Comparing loan offers does not affect your Schufa — comparison platforms use Schufa-neutral inquiries (Konditionsanfrage). Only a formal application triggers a visible inquiry. Repaying a loan on time actually improves your Schufa score over time.
