The topic briefly and concisely
A thorough selection of land takes into account the location, legal framework (development plan, land register), soil quality, and level of development.
The standard land value serves as a guide, but the actual market value can vary by 10-20%; a professional valuation is advisable.
Avoid common mistakes such as overlooked development costs (up to €15,000) or contamination by carefully reviewing all documents and circumstances.
Choosing the right plot of land is often the first and most crucial step towards your dream property or a profitable investment. However, many underestimate the significance of this decision, which goes far beyond the mere purchase price. A well-considered plot selection takes into account the location, legal framework, soil condition, and development potential. With a systematic approach and the right information, you minimise risks and lay the foundation for sustainable value. Discover which criteria truly matter and how to avoid pitfalls.
Laying the Foundation: Understanding the Key Criteria for Selecting a Plot
Site selection is a process with many variables. A thorough analysis of the location is essential. Pay attention to the connection to transport routes and the availability of infrastructure such as schools and shopping facilities, which can increase the value by up to 15%. The size and layout of the site must match your building plans; a rectangular layout is often considered ideal. Consider future developments in the area, which could positively or negatively influence the value. A good market analysis for sites helps to evaluate these factors. This first phase lays the foundation for all subsequent steps.
Overcoming Legal Hurdles: Focus on Zoning Plan and Land Register
Before investing, it is essential to review the legal framework. The development plan, for instance, regulates the permissible number of floors and construction method. A look at the land register reveals ownership relations and possible encumbrances such as mortgages or rights of way. In some federal states, the register of building encumbrances should also be consulted, as it may contain further obligations not recorded in the land register. The factors of land valuation are closely linked to these legal aspects. Early clarification of these points prevents future surprises that could incur costs of over 10,000 euros. Next, we will consider the physical characteristics of the land.
Soil Condition and Development: Technical Aspects of Site Selection
The physical characteristics of a plot of land are crucial for construction costs. A ground investigation provides insights into load-bearing capacity and groundwater levels. The costs for such an appraisal range between 500 and 1,000 euros but can prevent additional costs of tens of thousands of euros later. Pay attention to the development level: Are there connections for water, electricity, and sewage? The development costs can range between 8,000 and 15,000 euros. A fully serviced plot is usually more expensive but saves time and effort. Determine who bears the costs for any necessary development—often it is the buyer. These technical details are essential for a realistic building land potential assessment. Now onto the financial assessment of the plot.
Making Value-Oriented Decisions: Standard Land Value and Determining Purchase Price
The value of a building plot is determined by its location, size, and potential uses. The land value index, an average value per square metre, serves as an initial guide. It is assessed by appraisal committees at least every two years. You can find land value indices online in the BORIS-D system or at the respective offices. Please note that the actual market value can deviate by 10-20% from the land value index as individual plot characteristics are considered. Therefore, a professional analysis of land prices is advisable. Consider the following points for determining the purchase price:
Quality of location and infrastructure (can influence value by >10%)
Size and layout of the plot (optimal buildability)
Zone's land value index (e.g., 200 €/m²)
Development status (fully developed often >5% more expensive)
Buildability according to the development plan (e.g., ratio 0.4)
Any existing environmental or building regulations (can reduce value by >20%)
Comparable prices of similar plots in the region
A thorough evaluation protects against overpaying. Next, we summarise the key steps.
Strategic Property Search: From Online Platforms to Expert Consultation
How do you find the right property? Online portals like ImmoScout24 or Immowelt provide an initial market overview with thousands of listings. Inquiries at local councils can provide information on new development areas or funding programmes. Estate agents have local market knowledge and networks that can speed up the search process by up to 30%. Auctions can also be an option but require special caution and expertise. For an objective assessment and to evaluate the potential of unused land, consultation with experts like Auctoa can be worthwhile. With our ImmoGPT chat, you quickly receive initial assessments. The right search strategy is crucial for success.
Avoid common mistakes: cost traps and misjudgements when selecting a property
Many buyers underestimate the complexity of selecting a plot of land. A common mistake is insufficient scrutiny of the land register, which can lead to overlooked encumbrances. Development costs are also often not fully factored in; an undeveloped plot can quickly cost an additional €15,000. Contaminated sites, especially on land previously used for commercial purposes, pose a significant financial risk. Failure to consider the local development plan can mean that your dream home is not feasible. A careful examination of all aspects before purchase is therefore essential. Pay particular attention to the following points:
Unchecked land register extract: Hidden encumbrances can greatly restrict usage.
Overlooked development costs: Missing connections can quickly cause five-figure additional costs.
Ignored contaminated sites: Remediation costs can exceed the purchase price several times over.
Lack of insight into the development plan: Building desires may prove unfeasible.
Insufficient soil investigation: Poor soil quality can increase construction costs by over 20%.
Neglecting building charges: Can entail unexpected obligations and costs.
A comprehensive due diligence is key. How Auctoa can support you is covered in the next section.

Conclusion: The Right Selection of Property as a Success Factor
What is the difference between building land and land expected for development?
Building land is already developed and can be immediately built upon according to the zoning plan. Land expected for development is an area for which future construction is anticipated (e.g., as shown in the land use plan), but it is not yet developed or ready for building; there is a higher risk here and often a longer timeframe before it becomes buildable.
How can I identify contaminants on a property?
Indicators of contamination can arise from the previous use of the property (e.g., former industrial sites). Information is often available in the contamination registry of the relevant environmental authority or municipality. A soil assessment can provide clarity on actual contamination and its extent.
Who bears the notary costs when buying property?
Typically, the buyer bears the notary and land registry costs, which can amount to about 1.5% to 2% of the purchase price. However, it is possible to arrange different terms in the purchase agreement.
Is the land value the actual sale price?
No, the land value is an average figure for a specific area and serves only as a guideline. The actual sale price (market value) can vary due to specific characteristics of the property (e.g., precise layout, micro location, buildability), often by 10-20%.
What documents are important for buying property?
Important documents include a current land register excerpt, the zoning plan, possibly the building obligations register, the cadastral map, evidence of development and, for built properties, the energy certificate and building permits. A soil assessment is also often recommended.

FAQ
What is the difference between land for construction and land awaiting development?
Building land is already developed and can be built on immediately according to the development plan. Speculative land is an area where future development is expected (e.g. depicted in the land use plan), but it is not yet developed or ready for construction; this entails a higher risk and often a longer time frame until it is buildable.
How can I identify contaminated sites on a property?
Indications of contamination can arise from the prior use of the property (e.g., former commercial operations). Information is often available in the contaminated sites register of the responsible environmental authority or municipality. A soil survey can provide clarity about actual contamination and its extent.
Who bears the notary costs when buying a property?
Usually, the buyer bears the notary and land registry costs, which can amount to about 1.5% to 2% of the purchase price. However, it is possible to agree on different arrangements in the purchase contract.
Is the standard land value the actual sale price?
No, the standard land value is an average value for a specific zone and serves only as a guideline. The actual achievable selling price (market value) may vary due to specific characteristics of the property (e.g., precise plot shape, micro-location, buildability), often by 10-20%.
What documents are important for buying a property?
Important documents include a current land register extract, the development plan, possibly the land charge register, cadastral map, evidence of development, and for developed properties, an energy certificate and building permits. A soil report is also often recommended.
