How do I determine the rental price for my house
Are you wondering what rent is both appropriate and profitable for your house? A wrong calculation can cost you thousands of euros annually or lead to legal conflicts. This guide shows you how to determine the optimal rental price based on data and in compliance with the law.
With access to Google, BORIS, and Deep Research.
The local reference rent from the rent index is the most important basis for calculation.
In many cities, the rent control limits the rent increase for new leases to a maximum of 10% above the local comparable rent.
Location, condition, amenities, and energy efficiency are the key factors for optimizing the rental price within the legal range.
Setting the right rental price is one of the most critical decisions for property owners. A price set too high leads to vacancies, while one too low can reduce your return by up to 15% per year. Many owners rely on their gut feeling, risking significant losses or violations of rental price regulations. But how do you determine the rental price for your house so that it aligns with the market, legal requirements, and your return targets? In this article, you will receive a precise guide on how to correctly use the local comparative rent, evaluate value-enhancing features, and avoid legal pitfalls. This way, you secure sustainable income.
Before setting the rental price for your house, you must understand the legal frameworks. In Germany, the rent index and rent control primarily govern pricing. Since 2023, all cities with over 50,000 inhabitants are required to create a rent index, significantly increasing transparency. The rent index documents the local comparative rent, which is the average price per square meter for similar residential space. In areas with a tight housing market, rent control additionally applies, allowing a maximum deviation of 10% upwards for new rentals. Disregarding this 10% limit can lead to tenant claims for up to 30 months. Therefore, a precise understanding of these regulations is not optional but the financial and legal basis of your leasing. An initial orientation as to whether your property is located in such an area is provided by an online assessment for inherited apartments. These legal factors form the corridor within which you can adjust the price to the specific features of your property.
The single biggest factor affecting rent prices is location. Good transportation links can increase rental value by up to 15%. Here, a distinction is made between macro-location and micro-location. Macro-location describes the city or region, including its economic strength and population development. Micro-location, on the other hand, refers to the immediate surroundings of the property. Even a distance of just 500 meters from an underground station can increase the price per square metre by several euros. A detailed market analysis of the property is essential here. The following aspects of the micro-location are crucial:
Infrastructure: How far away are supermarkets, doctors, and schools? A well-supported local area can justify a surcharge of 5-10%.
Transport connection: The accessibility of motorways and public transport is a key factor for commuters.
Social environment: The image of the district, safety, and the quality of the neighbourhood directly influence people's willingness to pay.
Leisure value: Parks, green spaces, and cultural facilities nearby enhance the quality of life and thus the rent price.
A systematic assessment of these location factors is the next step to concretise the base value from the rental index.
In addition to the location, the characteristics of the house itself are crucial in determining the rental price. A modernised old building can often achieve a higher rent than an unrenovated new building from the 2000s. The energy certificate is a key document here, making energy consumption transparent and gaining importance for tenants. A good energy balance can reduce ancillary costs for the tenant by over 20% and justifies a higher base rent. Features such as a balcony or a modern fitted kitchen can increase the rental value per square metre by 1 to 3 euros. A professional property valuation helps to objectively quantify these factors. Pay particular attention to these value-adding features in your calculation:
Degree of modernisation: When were the bathroom, windows, and heating last renovated? Renovation within the last 5 years is a strong argument.
Quality of fittings: High-quality floors, a fitted kitchen, or a smart home system allow significant surcharges.
Additional areas: A garden, a terrace, or a cellar increase the utility value and thus the price.
Layout and brightness: Well-designed, bright rooms are more in demand and achieve on average 5% more rent.
These details determine where your house positions itself within the price range of the rent index and form the basis for comparison with other properties.
If there is no rental index for your municipality or if it is a detached house not recorded there, you must determine the local comparative rent yourself. The law requires the identification of at least three comparable properties for this purpose (§ 558 a para. 2 BGB). This method is demanding because comparability is interpreted very strictly. The comparable properties must significantly match in location, size, type, equipment, and condition. Even a deviation in living area of more than 10% can make the comparability contestable in court. To realistically assess the value of your house, it is best to use real estate portals for initial research. Look for listings from the last 12 months that are as close as possible to your house. Record the cold rents per square metre and calculate an average. This value serves as a solid basis for your rent price determination. If in doubt, the ImmoGPT chat from Auctoa can provide an initial assessment and help you find suitable comparative rents. With this data in hand, you can now strategically set the rental price.
The final rental price is a strategic decision between maximizing returns and minimizing vacancy risk. A rent set 5% too high can extend the marketing period by several weeks and nullify the return for an entire year. Use a rental yield calculator to explore various scenarios. Consider all costs, from the maintenance reserve (approximately 1% of the property's value per year) to management fees. Set the price slightly below the market average (about 2–3%) to attract a wider range of qualified tenants and reduce default risks. An index-linked rent, tied to the consumer price index, can be an option for regularly and conflict-free adjusting the rent without breaching the cap. Remember that long-term, stable leasing is often more profitable than maximizing possible rent with each tenant turnover. A well-founded strategy is the key to success.
Setting the rental price for your house is not a guessing game, but an analytical process. From adhering to legal limits like the rent cap to detailed analyses of location and amenities – each factor has a measurable impact on the achievable price. A systematic approach not only protects you from legal consequences but also secures your investment. A data-driven evaluation using tools like those from Auctoa can optimise your annual rental income by 5-10% by finding the perfect intersection between market acceptance and maximising returns. Don’t rely on estimates when it comes to your assets. A precisely calculated rental price is the foundation for worry-free and profitable renting.

What is the difference between 'Kaltmiete' and 'Warmmiete'?
The 'Kaltmiete' (net cold rent) is the basic charge for the use of the living space. The 'Warmmiete' includes additional advance payments for operating and ancillary costs such as heating, water, and waste disposal. The 'Kaltmiete' is always the basis for rent calculations and legal limits.
What does the rent cap mean?
The rent cap regulates rent increases in existing tenancies. It states that rent cannot increase by more than 20% within three years, or even just 15% in some tense markets. This applies even if the local comparative rent would allow a higher increase.
Does the rent brake also apply to new buildings?
No, the rent brake does not apply to apartments that were first used and rented out after 1 October 2014. Exceptions are also made for the first rental after a comprehensive modernization where the costs amount to at least one third of the expense for a comparable new building.
How often does a rent index need to be updated?
A simple rent index must be adjusted to market development every two years. A qualified rent index, which is compiled according to scientific principles, must be adjusted after two years and completely redone after no more than four years.
Can I, as a landlord, ignore the rent index?
No. The rent index is the legally recognised basis for determining the local comparative rent. A qualified rent index has significant evidential value in court. Ignoring it could work against you in a legal dispute.
What happens if I set the rent too high?
If your rent violates the rent brake, the tenant can reclaim the excess rent paid. If the rent is more than 20% above the comparative rent, this could constitute rent overcharge (an administrative offence) or even usury (a criminal offence) in the case of exploiting an emergency.
