Sell an apartment with a tenant: Rights, obligations & special considerations
Selling an apartment with a tenant – selling a rented condominium can be a profitable way to free up capital, reinvest tied equity, or strategically restructure a portfolio. However, the process comes with significant peculiarities: tenant rights, notice period restrictions, right of first refusal, and a significantly smaller pool of potential buyers lead in practice to price reductions of 20 to 35 percent compared to selling an empty property. Find all the details about the entire process in our Real Estate Sales Guide. In this article, you will learn what rights tenants have, how to find the right buyer, what tax pitfalls to watch out for, and how to achieve a market-appropriate price despite the rental agreement.
Selling an apartment with a tenant: What you need to know
The sale of a rented apartment is significantly more complex than the sale of an empty property. From the protection against termination under § 566 BGB to the tenant’s right of first refusal (§ 577 BGB) and up to the waiting periods for termination due to personal need (§ 577a BGB), there are numerous legal hurdles. Moreover: The buyer pool shrinks – end-users are out, investors become the main target group. Let’s take a closer look at the most important points.
Protection against termination: Sale does not end the lease (§ 566 BGB)
Selling the apartment does not terminate the rental agreement. The central principle “sale does not end the lease” is enshrined in § 566 BGB: The new owner assumes all rights and obligations of the existing lease agreement. Rent price, notice periods, clauses regarding cosmetic repairs, modernization agreements – everything remains unchanged. The tenant still has a right to undisturbed possession of the apartment as long as they fulfill their contractual obligations.
Practically speaking: Even though the rent has been below market level for years, the new owner cannot simply adjust the contract. Rent increases are only possible within the capping limit (15–20 percent over three years) and the local comparative rent. Exactly this point leads to significant price discounts for properties that are heavily under-let.
The most important facts at a glance:
- § 566 BGB: Purchase does not terminate the lease
- Buyer takes over the lease agreement including all clauses
- Security deposit also transfers to the buyer (§ 566a BGB)
- Rent increases are only possible within the legal framework
- Seller remains responsible for outstanding rent up to the handover
Rentaler’s right of first refusal (§ 577 BGB)
When an apartment building is first divided into individual condominiums and sold to third parties, the tenant is entitled to a statutory right of first refusal. This protective mechanism is intended to prevent tenants from being evicted from their apartments through conversion and sale. Important: The right of first refusal applies only to the first sale after division – not to every subsequent resale.
This is how the right of first refusal works in practice:
- Seller must inform the tenant in writing about the content of the purchase agreement
- Tenant has two months to exercise the right of first refusal
- Exercise of the right must be done in notarial form
- Tenant enters into the same conditions as the third-party buyer
- Exception: Sale to family members or household members – no right of first refusal applies here

Notice protection period after conversion (§ 577a BGB)
An often underestimated point: If a rental apartment is converted into a condominium and sold, the new owner is subject to a notice protection period for personal use and value-based termination. During this period, the buyer may not terminate the lease for personal use.
Overview of the protection periods:
- Federal minimum protection: 3 years from the transfer of ownership
- In tight housing markets (by state regulation): up to 10 years
- Applies to major cities such as Munich, Berlin, Hamburg, Cologne, Frankfurt
- The period begins with the registration of the new owner in the land register
For investors, this is neutral to positive – they want to keep the property rented out anyway. For self-occupying buyers, this lockout period can be a deal-breaker and effectively excludes this buyer group.
Lease termination agreement: The expensive, but clean solution
If you want to sell the apartment empty in order to achieve the higher self-occupying price, the lease termination agreement is often the only legally secure way. The tenant voluntarily waives his tenancy rights in exchange for a lump sum and moves out at an agreed time.
Market-standard compensation amounts:
- Standard: 6 to 12 net cold rents
- In tight markets: 12 to 24 net cold rents
- Approximate range: 10,000 € to 50,000 €, in prime locations also significantly more
- Rule of thumb: Compensation should be below the price difference between rented out and empty
Calculation example: An apartment in Munich with a cold rent of 1,200 € generates 480,000 € when rented out, and 620,000 € when vacant. Difference: 140,000 €. A severance payment of 30,000–50,000 € is economically sensible here, as net additional revenue of 90,000–110,000 € remains.
Landlord’s Right to View
Whether it’s a duplex apartment or a micro apartment – if you want to sell your apartment, you are allowed to arrange viewings. However, the right to view is clearly limited. The landlord must respect the tenant’s privacy, notify appointments in good time (usual: at least 3–4 days notice) and state the purpose.
What the courts consider reasonable:
- Maximum one viewing per week
- Weekdays between 10 and 7 pm, limited on Saturdays
- Notice period: at least 24 hours, better 3–7 days
- Viewing duration: max. 30–45 minutes per appointment
- Group viewings with multiple interested parties are allowed, but not mandatory
Tip from practice: Offer the tenant a small reimbursement (e.g. 50–100 € per appointment) or a one-time compensation. This significantly reduces conflicts and ensures cooperative appointments.

Private users: Termination due to personal need
Requirements for a valid termination due to personal need
If the landlord needs the apartment for themselves or close relatives, a termination due to personal need is possible – but only under strict conditions. A general statement is not sufficient; the need must be specifically and verifiable.
Who counts as “close relatives”:
- Spouses, registered life partners, children, parents
- Siblings, grandparents, grandchildren
- In-laws, in-law children (under certain circumstances)
- Caregivers for family members in the household
Notice periods in case of personal need
The statutory notice periods depend on the rental duration:
- Rental duration up to 5 years: 3 months notice period
- Rental duration 5 to 8 years: 6 months
- Rental duration over 8 years: 9 months
- In case of conversion: additional 3–10 year waiting period (§ 577a BGB)
Hardship clause and risks
The tenant can file an objection under § 574 BGB if the termination would cause particular hardship – for example, in cases of old age, serious illness, pregnancy or lack of alternative accommodation. In addition, caution is advised: if the stated personal need is not subsequently implemented (“fabricated personal need”), claims for damages in the five- or six-figure range may arise.
Requirements for an effective personal need termination at a glance:
- Lawful, specific interest of the landlord
- Personal use for themselves or close relatives
- Written justification with name and reason for the need
- Compliance with legal notice periods
- Observance of the blackout period after conversion
- Actual implementation after moving out is mandatory
Rented vs. vacant: The direct comparison
The decision “sell rented or sell vacant” has significant financial consequences. Here is a direct comparison of the most important factors:
| Criterion | Rent out sell | Empty sell |
|---|---|---|
| Selling price | 20–35 % below market value | 100 % market value |
| Buyer group | Investors, investors | End-users + investors |
| Marketing duration | Often longer (3–6+ months) | Usually faster (1–3 months) |
| Evaluation standard | Rent multiplier / return | Comparative value / asset value |
| Viewing effort | High (tenant coordination) | Low (always possible) |
| Home staging possible | No | Yes |
| Risk of rental default | To be borne by the buyer | Not relevant |
| Negotiation room | Limited | Larger |

Investors as target group: How investors think
Evaluation via the rent multiplier
While end-users buy emotionally and use comparative prices as a benchmark, investors evaluate real estate purely numerically via the rent multiplier (also: multiplier). The formula: purchase price ÷ annual net cold rent = factor.
Market factors per location:
- A-locations (Munich, Hamburg city center): factor 30–45
- B-locations (Dusseldorf, Stuttgart, Cologne): factor 22–32
- C-locations (medium-sized cities): factor 16–24
- D-locations (medium towns): factor 12–18
Example calculation: An apartment with a cold rent of 1,000 € (12,000 € per year) achieves a selling price of 420,000 € in Munich with a factor of 35, but only 264,000 € in Leipzig with a factor of 22. Anyone who is subletting should check before selling whether a legally secure rent increase is possible – every additional euro of monthly rent increases the selling price by the factor × 12.
Which types of investors are suitable?
- Private investor: Seeks 1–3 properties for retirement, factor-oriented
- Owner / Family Office: Buys portfolios, focuses on cash flow and location quality
- Fix-and-Flip Investor: Seeks properties with potential for value increase, often with expiring rental agreements
- Institutional investors: Relevant only from portfolio sizes upwards, high return requirements
Tax aspects when selling
Speculation tax (§ 23 EStG)
If an rented apartment is sold within 10 years after acquisition, speculation tax at the rate of your personal income tax rate (up to 45 % plus solidarity surcharge) applies to the profit. The period begins with the date of the notarized purchase contract – not with handover or land register entry.
