Do you own a property as an heir or owner? Then you're faced with the challenge of securing its value in a dynamic market. Many owners underestimate the speed at which a property can lose value – be it due to creeping maintenance backlogs or outdated energy standards. This guide provides you with data-driven strategies rather than gut feelings. Discover how you can lay the foundation for stable value retention and minimise financial risks through proactive maintenance, targeted modernisations, and smart analyses. This way, your property becomes a safe and profitable investment for the future.
Proactive Maintenance as the Foundation of Value Preservation
A property requires continuous maintenance to preserve its value. Experts recommend setting aside 1% to 2% of the property's value annually for maintenance. For a property worth €500,000, this equates to a budget of €5,000 to €10,000 per year. The Immobilienwertermittlungsverordnung (ImmoWertV) estimates the cost to be approximately €11.70 per square metre of living space annually.
Regular inspections every two to three years by professionals can identify potential problems early. This helps to avoid costly consequential damages that significantly reduce value. Comprehensive documentation of all maintenance work is essential for the quality standard of an appraisal and builds trust with potential buyers. Neglected maintenance can lead to a loss of value exceeding 15%.
The most important regular measures include:
Roof and façade inspection to prevent moisture damage.
Maintenance of the heating system to ensure efficiency and prevent breakdowns.
Painting the façade every 10 to 15 years to protect the building fabric.
Checking windows and doors for tightness to reduce energy costs.
This proactive approach not only protects the building's fabric but also forms the basis for value-enhancing measures such as energy-efficient refurbishments.
Value driver energy refurbishment: Increase efficiency, reduce costs
Energy efficiency has become one of the most important criteria for property value. An energy refurbishment can increase a property's market value by up to 25%. Nevertheless, the renovation rate in Germany is only 0.69% in 2024, far below the 2% required for climate targets. Around two-thirds of residential buildings in Germany fall into the inefficient energy classes D to H, which offers enormous potential for value increases.
Government subsidies, such as those from the KfW Bank, make the investment even more attractive. For refurbishment into an efficiency house 85, for example, you can receive a grant of up to €36,000. [] These investments not only reduce ongoing energy costs by up to 80% but also make your property future-proof against legal requirements such as the Building Energy Act (GEG).
An energy-efficiently modernised old building is particularly in demand in the market. The demand for energy-efficient properties is steadily increasing, as buyers want to avoid rising energy costs and the risk of refurbishment obligations. A good energy balance is therefore a direct selling point. Investing in energy efficiency is therefore not only a contribution to climate protection but also a clear strategic decision for value retention.
Location Analysis: How Location Impacts Property Value in the Long Term
The location remains one of the most crucial factors for the preservation and increase of a property's value. Over the last 20 years, property prices in Germany have increased by an average of 63%, with developments varying greatly depending on the region. A good macro location in a economically stable region with positive demographic development forms the basis for long-term positive value growth.
The micro location is often even more important. The immediate surroundings with good infrastructure can increase the value by over 15%. This includes good access to public transport, proximity to schools, shopping facilities and green spaces. Even in a tight market, properties in preferred locations achieve more stable prices and are quicker to sell.
A detailed market analysis for your property helps identify local development projects or zoning plans that could influence the value in the future. Negative factors such as noise pollution or lack of infrastructure must also be taken into account in the evaluation. Therefore, location analysis is an indispensable step to fully exploit the potential of targeted modernisations.
Targeted Modernisation: Investments with the Highest ROI
In addition to energy-efficient renovations, there are other modernisations that can significantly increase the value of your property. It is crucial to make investments that meet current living demands. Modern and high-quality features can increase the sale price by 10% to 20%. This isn't about luxury, but about contemporary comfort and functionality.
The following measures often offer a high return on investment (ROI):
Bathroom and kitchen modernisation: These rooms are particularly scrutinised by buyers. An investment of €10,000 can increase the sale value by up to €15,000.
Optimising floor plans: Open living concepts are in demand. Removing a non-load-bearing wall can make a room appear brighter and more spacious.
Floor coverings and walls: New, high-quality flooring like parquet and a fresh coat of paint in neutral colours create an attractive basis.
Accessibility: Measures such as a level-access shower broaden the target audience and ensure value retention with demographic changes in mind.
A well-thought-out strategy for long-term value enhancement combines maintenance with targeted upgrades. Not every expensive measure pays off; the focus should be on visible improvements in quality and living comfort. These investments are often the key to a successful sale.
Actively prevent building damage and protect the structure
The greatest enemy of property preservation is undiscovered structural damage. In particular, moisture can cause lasting damage to the building fabric and lead to a depreciation of up to 20%. Often, it is small defects such as leaking joints or hairline cracks in the facade that cause large and costly problems over the years. The most common cause of structural damage is penetrating moisture.
A practical analysis by ETH Zurich found that a building generally has 15 defects on average. Regular inspections by a specialist are therefore essential to detect such risks at an early stage. The costs for rectifying serious structural damage can quickly exceed €50,000, making preventive checks the most economical solution.
To minimise risks when selling a house, transparent communication about the property's condition is crucial. Structural damage does not have to be a deal-breaker if it has been professionally repaired and documented. This shows that you have acted responsibly as the owner. Careful maintenance of the building fabric is the basis for any precise and positive property valuation.
Comprehensive documentation as the basis for an accurate assessment
A complete and proper documentation is crucial for maintaining value and navigating the sales process. Missing documents, such as building permits, current land registry extracts, or evidence of renovations, create uncertainty and can delay the sales process by weeks. Potential buyers might make lower offers to compensate for their risk.
A transparent and complete set of documents can positively influence the final sale price by up to 5%. It signals professionalism and establishes a solid foundation of trust. Key documents include land registry extracts, energy performance certificates, building plans, invoices from craftsmen, and maintenance logs.
A professional valuation relies significantly on these documents. With digital tools like Auctoa ImmoGPT, you can assess the relevance of your documents and understand which measures have the greatest impact on your valuation. This ensures that the value of your property is not only guaranteed on paper but also in reality.
preservation of value
Preserving the value of a property is not a coincidence, but the result of strategic planning and consistent action. From regular maintenance, which should account for 1-2% of the property's value annually, to energy-efficient refurbishment that can increase value by up to 25%, a proactive approach is essential. Location remains a key factor, but targeted modernisations and the prevention of structural damage are equally crucial.
A comprehensive documentation completes the picture and provides the required transparency for optimal valuation. Use data-driven tools to make informed decisions and fully realise the potential of your property. Ultimately, a well-maintained property is the best retirement plan and a stable asset.
