Most people know two kinds of rental: a holiday apartment booked for a week on Airbnb, or a long-term unfurnished flat signed for years. But for an expat arriving in Berlin for a six-month project, a professional relocating to Munich before finding a permanent home, or a student completing a semester abroad, neither option fits. The stay is too long for a hotel or holiday let, and too short to justify signing an indefinite lease, buying furniture, and setting up utility contracts. This is the gap mid-term rental was built for.
Mid-term rental describes a furnished apartment or house rented for a defined period, typically between one and twelve months, under a fixed-term contract. It combines the move-in convenience of a holiday let with the stability and legal protection of a proper residential tenancy. In Germany, it is a well-established and fully legal category, governed by the Zeitmietvertrag (fixed-term lease) under §575 of the German Civil Code (BGB). Understanding what mid-term rental is, how it differs from the alternatives, and how contracts work protects both tenants and landlords from costly misunderstandings.
Key takeaways
- Mid-term rental typically means a furnished apartment rented for one to twelve months under a fixed-term contract (Zeitmietvertrag).
- It sits between short-term holiday lets (days to a few weeks) and long-term unfurnished leases (one year or more), filling a clear gap for mobile professionals, expats, and people in transitional housing.
- In Germany, mid-term contracts are governed by §575 BGB. They must state a legally valid reason for the fixed term in writing. All standard BGB tenant protections apply for the full duration.
- Landlords benefit from higher monthly yield than unfurnished lets and more stable income than short-term holiday rentals, with lower turnover costs and a clearly defined professional tenant base.
- Platforms like Wunderflats handle the legal contract, tenant verification, and payment infrastructure, making mid-term rental accessible to landlords without specialist knowledge.
What is mid-term rental?
Mid-term rental is a furnished residential tenancy for a fixed period, most commonly one to twelve months. The apartment is ready to move into on arrival: furniture, bedding, kitchen equipment, and appliances are all provided. The contract has a defined start and end date agreed by both parties before the tenancy begins. Utilities and Wi-Fi are often included in the monthly price, either as a flat fee or as a separately stated advance.
The concept occupies a distinct middle position in the rental market. Short-term rentals (holiday lets, Airbnb-style bookings) are designed for stays of days to a few weeks. They carry no residential tenancy protections, no Anmeldung rights, and rates built around tourist demand. Long-term rentals (the standard German Mietvertrag) are open-ended, typically unfurnished, and built around multi-year tenancies with strong statutory protections but very limited flexibility. Mid-term rental was designed for everyone who falls between these two: people who need a proper home for a defined and foreseeable period, fully equipped, with a legally sound contract and the ability to register their address.
The term "mid-term rental" is used internationally. In Germany, the closest legal and practical equivalent is the Zeitmietvertrag for a möblierte Wohnung (furnished apartment). Platforms that specialise in this category: Wunderflats being the largest in Germany: have standardised the product and made it reliably available at scale in major German cities.
Key characteristics
Mid-term rentals share a consistent set of features that distinguish them from both short-term and long-term alternatives. The table below captures the defining attributes.
| Characteristic | Detail |
|---|---|
| Contract length | Typically 1 to 12 months. Some platforms allow up to 24 months for longer assignments. The end date is fixed in the contract. |
| Furnishing level | Fully furnished: bed, sofa, dining table, wardrobes. Fully equipped kitchen. Linen and towels often included. |
| Appliances | Washing machine, refrigerator, oven or hob, microwave. Dishwasher common in higher-spec units. |
| Internet | Wi-Fi included in nearly all mid-term rentals. No separate contract required. |
| Utilities | Often included as a flat fee or Nebenkosten advance. Electricity, water, and heating are the most common inclusions. Confirm before booking. |
| Typical tenant profile | Expat on work assignment, professional on relocation, intern or student, person between homes (renovation, divorce, job change). |
| Contract type (Germany) | Zeitmietvertrag (fixed-term lease) under §575 BGB. Must state a valid reason for the fixed term in writing. |
| Notice period | Tenancy ends automatically at the agreed date. No notice required from either party unless stated otherwise in the contract. |
| Anmeldung (address registration) | Permitted. Landlord must provide a Wohnungsgeberbestätigung. Required for bank accounts, tax IDs, and public services. |
| Regulatory status (Germany) | Fully legal residential tenancy. All BGB tenant protections apply. Not classified as a holiday let or short-term commercial accommodation. |

How it compares: short-term, mid-term, long-term
The three categories of rental serve fundamentally different needs. Understanding where mid-term sits helps tenants choose the right option and helps landlords position their property correctly. The table below compares them across the attributes that matter most.
| Attribute | Short-term (Airbnb, holiday let) | Mid-term rental | Long-term (standard Mietvertrag) |
|---|---|---|---|
| Typical duration | Days to a few weeks | 1 to 12 months (fixed) | 1 year or more (open-ended) |
| Furnished | Always | Always | Rarely (usually unfurnished) |
| Utilities included | Yes (in nightly rate) | Often (flat fee or advance) | Separate contracts required |
| Contract type (Germany) | None or commercial accommodation agreement | Zeitmietvertrag (§575 BGB) | Unbefristeter Mietvertrag (open-ended BGB lease) |
| BGB tenant protections | None (tourist accommodation) | Full protections for contract duration | Full protections (strongest tenure) |
| Anmeldung possible | No (in practice) | Yes | Yes |
| Typical monthly cost (Berlin 2-bed) | 3,000–6,000 EUR (nightly rate × 30) | 1,600–2,800 EUR (all-in) | 1,200–1,800 EUR Kaltmiete + setup costs |
| Flexibility for tenant | Very high (book and cancel easily) | Medium (fixed dates, some extension possible) | Low (3-month notice period, unfurnished exit costs) |
| Flexibility for landlord | Very high (short bookings) | Medium (fixed end date, limited early exit) | Very low (strong tenure, Eigenbedarf rules apply) |
| Local registration rules (Germany) | Subject to city-level short-term let restrictions (e.g. Zweckentfremdungsverbot) | Regulated as standard residential tenancy | Regulated as standard residential tenancy |
For a tenant who needs a home for two to nine months, mid-term rental is almost always the most practical and cost-effective choice. It avoids the prohibitive nightly rates of short-term accommodation, and it avoids the upfront cost and administrative burden of setting up a long-term unfurnished tenancy for a short stay.
Who uses mid-term rentals
Mid-term rental is not a niche product. It serves a wide and growing population of mobile, professionally active people who have a temporary but genuine need for a proper home. The four main groups are described below.
Expats and professionals on work assignment
A professional arriving in Frankfurt for a three-month consulting project or a software engineer relocating from Amsterdam to Berlin for an eight-month contract needs housing immediately, without committing to a two-year lease in a city they are still getting to know. Mid-term rental provides a fully equipped home from day one, with a contract that matches the assignment duration. Many employers and relocation agents now book mid-term rentals directly as part of a standard onboarding package.
People relocating and searching for a permanent home
Finding the right long-term apartment in a competitive German city takes time: often two to four months of active searching, viewings, and waiting lists. A mid-term rental gives the newly relocated person a stable, comfortable base during that search, without pressure to sign the first available long-term lease. They can explore neighbourhoods, understand local rent levels, and make an informed decision rather than a rushed one.
Students and interns
University exchange students and internship candidates typically need housing for one semester (three to six months). Student halls and short-term sublets are often difficult to secure and heavily competed for. Mid-term rental platforms offer verified, professionally managed apartments that match semester or internship timelines precisely, without the complexity of an open-ended Mietvertrag.
People between homes
Life events regularly create temporary housing needs: a flat being renovated, a separation or divorce, a gap between selling one property and completing the purchase of another, or a move back to Germany after years abroad. For all of these situations, mid-term rental provides a properly furnished, legally sound home for a defined period, without the disruption of hotel living or the inflexibility of a new long-term commitment.
ℹ Info: Corporate housing teams and relocation agencies in Germany increasingly specify mid-term rental as the default accommodation solution for assignees. The fully managed, all-inclusive format reduces administrative overhead for both the employer and the employee on arrival.
Why landlords offer mid-term rentals
Mid-term rental has become an attractive option for private landlords and property investors in Germany for three interconnected reasons: yield, stability, and manageability.
Higher yield than long-term letting
A furnished mid-term apartment commands a higher monthly rent than the same unit let unfurnished on an open-ended basis. The furnished premium typically ranges from 20% to 40% above comparable Kaltmiete, reflecting the cost and convenience of the full fit-out. For landlords in cities subject to Mietpreisbremse (rent brake), furnished mid-term rentals may be partially exempt from the rent cap, depending on how the furniture premium is structured. This makes mid-term rental particularly valuable in tight regulatory environments.
More stable than short-term holiday letting
Running an Airbnb in a major German city carries significant regulatory risk. Berlin, Munich, Hamburg, and other cities have introduced Zweckentfremdungsverbote (misuse prohibition laws) that restrict or prohibit using residential apartments as permanent short-term tourist accommodation. Mid-term rental avoids these restrictions entirely: it is a residential tenancy, not tourist accommodation. It also avoids the operational burden of nightly changeovers, constant guest communication, and high platform commission rates.
Lower turnover cost than nightly lets
A landlord on a mid-term model might handle four to six tenant changeovers per year, compared to 150 or more with nightly Airbnb bookings. Each changeover involves cleaning, key handover, and inspection. Mid-term tenants also tend to treat apartments with more care than tourists: they are living there, registering their address, and have signed a proper lease. The combination of fewer changeovers and more careful occupants reduces wear, maintenance costs, and the landlord's time investment significantly.
💡 Tip: Landlords considering the switch from long-term to mid-term letting should calculate the all-in annual yield including furnishing amortisation, platform fees, and void periods between tenancies. For many city-centre apartments, mid-term letting produces a meaningfully better net return than a standard unfurnished Mietvertrag.
What is typically included
One of the defining characteristics of mid-term rental is that the apartment is genuinely move-in ready. Tenants arrive with a suitcase and find everything they need to live comfortably from the first night. The exact scope of inclusions varies between landlords and platforms, but the standard is consistent across the market.
- Furniture: bed with mattress, sofa and seating, dining table and chairs, wardrobes and storage, desk in most cases.
- Kitchen equipment: refrigerator, oven or hob, microwave, kettle, basic cookware, utensils, crockery, and glassware.
- Appliances: washing machine (and dryer where space allows), dishwasher in most higher-spec apartments.
- Linen and towels: included by most platforms and many private landlords, particularly at initial move-in.
- Internet: Wi-Fi included in nearly all mid-term rentals. No separate broadband contract required.
- Utilities: electricity, water, and heating are commonly included as a flat fee or as a Nebenkosten advance within the monthly rent. Always confirm the exact arrangement before booking.
- Cleaning: some landlords and platforms include a periodic cleaning service or an end-of-tenancy clean. This varies: check the listing details.
⚠ Warning: "All-inclusive" means different things on different platforms. Some include utilities as a flat monthly fee with no reconciliation. Others charge a Nebenkosten advance with an annual settlement that may result in an additional payment. Read the contract carefully and ask the landlord to confirm exactly which costs are covered before you sign.
Legal framework in Germany
Mid-term rental in Germany is not a grey area. It is a well-defined legal category governed primarily by §575 of the Bürgerliches Gesetzbuch (BGB). Understanding the legal structure protects both parties and avoids the risk of a contract being deemed invalid.
The Zeitmietvertrag (fixed-term lease)
A Zeitmietvertrag is a residential lease with a defined end date. Unlike the standard German rental contract (unbefristeter Mietvertrag), which runs indefinitely until one party gives notice, a Zeitmietvertrag ends automatically on the agreed date. No notice is required from either side: the tenancy simply concludes. This structure is what makes mid-term rental work: both the tenant and the landlord know from the outset exactly when the arrangement ends.
§575 BGB: requirements for a valid fixed-term lease
Not every fixed-term contract is automatically valid under German law. §575 BGB sets strict conditions. The contract must be in writing. It must state a legally recognised reason for the fixed term at the time of signing. Without a valid stated reason, German courts treat the contract as open-ended: the fixed-term clause is void, and the tenancy runs indefinitely.
The three legally recognised reasons under §575 BGB are:
- Eigenbedarf: The landlord, or a family member or household member of the landlord, intends to use the apartment personally after the tenancy ends.
- Planned substantial renovation: The landlord intends to carry out significant building work that requires the apartment to be vacant for the duration.
- Staff housing: The apartment is intended to be let to an employee of the landlord after the tenancy ends.
Eigenbedarf is the most commonly used reason in the mid-term rental market. A landlord who owns an apartment but is working abroad, living elsewhere temporarily, or expects to need the property back for a family member can offer it as a mid-term rental under this provision. Platforms like Wunderflats ensure that contracts include a correctly stated reason and meet all §575 BGB requirements.
Tenant protections during a mid-term tenancy
A common misconception is that mid-term tenants have fewer rights than long-term tenants. This is not correct. For the full duration of a Zeitmietvertrag, all standard BGB tenant protections apply. The landlord cannot raise the rent beyond statutory limits, cannot enter the apartment without notice, cannot withhold the security deposit without a valid claim, and cannot end the tenancy before its stated end date without a serious lease violation by the tenant.
The security deposit (Kaution) is capped at three months of cold rent (Kaltmiete) under §551 BGB, exactly as in any other German residential tenancy. The landlord must hold it in a separate interest-bearing account and return it within a reasonable period after the tenancy ends, minus any legitimate deductions.
ℹ Info: If the landlord's stated reason for the fixed term turns out to be false (for example, the landlord does not actually move in after the tenancy ends), the tenant may be entitled to compensation under §575a BGB. This can include reimbursement of moving costs and the difference in rent at a new property. Platforms and landlords using legitimate Zeitmietverträge are bound by this provision.
Furnished apartments and the Mietpreisbremse
Germany's Mietpreisbremse (rent brake) caps rents on new lets in designated areas at no more than 10% above the local comparative rent (Mietspiegel). Furnished apartments may be partially exempt from this cap. Landlords are permitted to add a reasonable furniture surcharge on top of the regulated rent: this surcharge is not subject to the Mietpreisbremse, but it must genuinely reflect the cost and depreciation of the furnishings provided, and it must be transparently disclosed in the contract. Tenants have the right to request a breakdown of the furniture surcharge if it appears disproportionate.
How mid-term rental platforms work
The mid-term rental market in Germany is served by a small number of dedicated platforms that have built infrastructure specifically for stays of one to twelve months. These platforms solve the core problems that historically made mid-term rental difficult: the absence of standardised contracts, inconsistent property quality, payment security, and the difficulty of matching tenants who need housing quickly with landlords who are not property professionals.
Wunderflats: the leading platform in Germany
Wunderflats is Germany's largest mid-term rental platform, operating in all major German cities including Berlin, Munich, Hamburg, Frankfurt, Cologne, and Düsseldorf. Founded in 2015 and headquartered in Berlin, the platform connects private landlords and property managers with verified professional tenants: primarily expats, corporate transferees, and mobile workers.
Wunderflats provides a standardised, legally compliant Zeitmietvertrag in both German and English as part of every booking. The contract is generated automatically based on the agreed rental period, the stated §575 BGB reason, and the property details. Landlords do not need specialist legal knowledge to offer their apartment compliantly: the platform handles the legal framework.
Tenants are verified before booking: identity documents are checked, professional background is confirmed, and payment is secured. Landlords receive payment monthly through the platform, with Wunderflats handling invoicing and acting as an intermediary layer that reduces risk for both parties. The platform also handles the Wohnungsgeberbestätigung process, ensuring tenants can complete their Anmeldung without friction.
What the platform model means in practice
For tenants, booking through a platform like Wunderflats means the apartment has been inspected and photographed professionally, the contract is valid and BGB-compliant, the landlord is verified, and there is a clear point of contact for support during the tenancy. This matters particularly for expats arriving from outside Germany who cannot easily assess German legal documents or verify a landlord's legitimacy independently.
For landlords, the platform provides a reliable pipeline of qualified tenants, a managed payment process, standardised contracts that reduce legal risk, and a professional support layer that reduces the day-to-day management burden. Landlords pay a service fee to the platform in exchange for these services: fee structures vary and should be reviewed before listing.
FAQs about mid-term rental
Is mid-term rental legal in Germany?
Yes. Mid-term rental is fully legal in Germany when structured correctly. It uses a Zeitmietvertrag (fixed-term lease) under §575 BGB. The contract must state a legally valid reason for the fixed term in writing at the time of signing. All standard tenant protections under the BGB apply for the duration of the tenancy.
How does mid-term rental pricing compare to long-term rental?
Mid-term rentals typically cost more per month than unfurnished long-term leases. The higher price reflects the full furnishing, included appliances, and often Wi-Fi and utilities. Landlords also price in the shorter contract duration and the cost of periodic tenant changeovers. In practice, the all-in monthly cost of a mid-term rental is often comparable to or lower than the combined cost of a long-term unfurnished apartment plus furniture, utility setup, and Wi-Fi contracts.
Do I need a special contract for a mid-term rental in Germany?
Yes. A mid-term rental in Germany uses a Zeitmietvertrag (fixed-term lease) under §575 BGB. This must be in writing and must state a legally valid reason for the fixed term at the time of signing. Common valid reasons include Eigenbedarf (the landlord or a family member intends to use the property) or substantial planned renovation. Platforms like Wunderflats provide standardised, legally compliant bilingual contracts as part of the booking process.
Can the landlord end a mid-term contract early?
Generally no. A Zeitmietvertrag runs to its stated end date. The landlord cannot terminate it early without a serious lease violation by the tenant (such as persistent non-payment of rent). This is one of the key protections for mid-term tenants in Germany: the end date is fixed, and both parties are bound by it.
Can I register my address (Anmeldung) in a mid-term rental in Germany?
Yes. You can register your address with the local Einwohnermeldeamt (residents' registration office) in a mid-term rental, provided the landlord supplies a Wohnungsgeberbestätigung (confirmation of residence). Reputable mid-term platforms ensure landlords provide this document. Anmeldung is required for most official purposes in Germany, including opening a bank account, registering with a doctor, and obtaining a tax ID.
What is typically included in a mid-term rental?
A mid-term rental is always fully furnished and equipped with all major appliances. Most include Wi-Fi. Many include utilities (electricity, water, heating) in the monthly rent as a flat fee. Some include a cleaning service or linen changeover. The exact inclusions vary by landlord and platform: always confirm what is covered before booking.
