The topic briefly and concisely
Informed decision support is essential in real estate, as many owners do not know the value of their property and risk financial disadvantages.
Modern decision support uses data-driven analyses and AI to improve price forecasts and minimize risks.
Neutral evaluations, especially in matters of inheritance, can help avoid conflicts of interest and optimize tax burdens.
The decision to buy or sell a property, whether as an heir, owner, or investor, is often associated with significant financial consequences. Market uncertainties and the complexity of valuation methods can quickly lead to poor decisions. This article highlights how structured decision support, based on neutral data and modern analysis methods, can help you minimize risks and optimize the value of your property investments. We show you ways to move from purely intuitive decisions to data-driven strategies.
Creating the Foundation: Why Solid Decision Support is Essential
Many property owners face significant challenges: According to a survey, 46 percent of property owners in Germany are unaware of the actual value of their property. This lack of knowledge can lead to considerable financial disadvantages when it comes to selling, financing, or inheritance issues. A professional valuation is therefore an initial, crucial step towards well-informed decision-making support.
Research shows that the primary scientific contributions in the field of decision support focus on investments and valuations. However, research into real estate decision support systems (DSS) still appears to be in its infancy. This highlights the need for practical solutions that assist owners and investors in navigating the complexities of the market. A solid data foundation is key to this.
Data-Driven Insights: The Path to Better Property Decisions
Modern decision support relies on data-driven analyses. Data analytics solutions use extensive historical data and advanced analytical techniques to make precise predictions about property prices and market demand. For instance, a property investor was able to increase the accuracy of their price forecasts by 25% using such solutions. This enables strategic planning and risk minimisation.
Property valuation is undergoing a fundamental transformation due to artificial intelligence (AI) and machine learning. AI-supported valuations can react to market changes in real-time and perform complex analyses more quickly. These technologies significantly reduce time and errors. Such tools are of great benefit for an accurate valuation.
The following aspects particularly benefit from data-supported decision making:
Price forecasts: Precise predictions of future property prices.
Rental yield analysis: Identification of profitable investment opportunities.
Market demand trends: Understanding future demand in various segments.
Risk assessment: Minimising potential risks through well-founded data analyses.
The use of such technologies leads to more transparent and objective decision-making.
Neutral assessment as a foundation: Avoiding conflicts of interest
Especially in emotionally charged situations like inheritances, neutral decision support is invaluable. The tax office often defines the property value using a highly simplified procedure, without a visit. This can lead to inflated values and consequently to unnecessarily high inheritance taxes. Heirs can document the lower value through an independent appraisal according to § 198 of the Valuation Act.
A neutral market value appraisal by an expert can remedy this and often save thousands of euros in taxes. The determination of the market value should always be carried out by a qualified property expert who assesses the value professionally, accurately, and impartially. This is an important pillar of the role of appraisers.
The advantages of a neutral assessment are manifold:
Builds trust and transparency, especially in communities of heirs.
Serves as a solid basis for payouts or sales proceeds.
Prevents lengthy and costly disputes.
Provides a realistic basis for tax calculations.
An objective evaluation is therefore a cornerstone of any good decision support.
Modern Tools: AI and Digital Systems in Decision Support
Artificial Intelligence (AI) is revolutionising decision support in property valuation. Automated Valuation Models (AVMs) use machine learning to estimate property values based on large datasets. The Sprengnetter AVM, for instance, combines purchase prices, offer data, and sociodemographic information for quick estimates. Such systems are particularly suitable for standard properties and support various stakeholders in the real estate market.
In addition to AVMs, deep learning is used in image recognition to analyse building types or renovation statuses based on photos. Large Language Models (LLMs) assist with text-based specialist research and information extraction. These tools significantly enhance information quality and research speed. The helpful tools are diverse.
The challenges with AI-supported methods lie less in the technology itself and more in data quality, model transparency, and user acceptance. Nevertheless, AI-supported property valuation is already a reality and will not replace experts but make their work more efficient. The future belongs to hybrid methods that combine human and machine capabilities.
Understanding legal frameworks and recognized procedures
For legally sound decision support, knowledge of the legal foundations is essential. In Germany, property valuation is subject to strict regulations, particularly the Property Valuation Ordinance (ImmoWertV) and the Building Code (BauGB). Only three methods are legally recognised and valid in court: the comparative value method, the income value method, and the cost value method. The choice of the correct method depends on the type of property and the purpose of the valuation.
The comparative value method is based on actual sale prices of similar properties and often provides realistic market values. The cost value method focuses on the material value and is suitable for owner-occupied properties. The income value method is used for investment properties and is based on expected rental income. A property appraiser uses these recognised methods to accurately determine the market value. Knowledge of these valuation strategies is crucial.
An overview of the main methods:
Comparative value method: Based on sale prices of comparable properties.
Income value method: Based on future expected income (rentals).
Cost value method: Determines the value based on construction costs and land value.
Professional decision support takes these methods into account and selects the appropriate method for your specific situation. For complex cases, as can occur in property appraisal, this is especially important.
Risk management: Addressing uncertainties with intelligent decision support
Every real estate investment carries risks. Effective decision support helps to identify and manage these risks. The prevailing concept of risk in the real estate industry is often inadequate and needs to be expanded to include a psychological dimension to unlock its potential for EUS applications. AI systems can provide valuable assistance here by supplying not only estimates but also additional statistical information such as ranges of dispersion and risk classifications.
This adds value to portfolio analyses and the risk management of banks and insurers. By identifying emerging trends and predicting future developments, you can plan strategic investments and minimise risks. A well-thought-out strategy for risk minimisation is essential.
