The topic briefly and concisely
The additional costs when purchasing a property (land transfer tax, notary, estate agent) can amount to 10-15% of the purchase price and should be factored in early.
Development costs for connecting to public networks (water, electricity, etc.) can range between €25,000 and €50,000 for an average plot.
The standard land value provides an initial guideline for the property value, but individual factors such as location, layout, and buildability significantly influence the actual price.
The dream of owning a home begins with the plot of land – but how can its price be realistically assessed? Many prospective builders underestimate the complexity of estimating the costs for a plot of land. In addition to the pure purchase price, there are various additional costs that can quickly account for 10-15% of the purchase price. This article guides you through all relevant cost points, from development measures to notary fees, and helps you establish a solid financial foundation for your construction project. This way, you can make informed decisions and safeguard your investment.
Basics of Property Costs: More Than Just the Purchase Price
The determination of the total costs for a property is a multi-step process. The purchase price itself, often prominently displayed in the brochure, is just the tip of the iceberg. Many buyers overlook that additional costs can make up to 15% of the property's price. These extra expenses are crucial for a realistic valuation and budget planning. The most important additional costs include the property transfer tax, notary and land registry fees, as well as possible estate agent commissions. A careful listing of all items is essential to correctly assess the financial implications of the property purchase. Knowing these factors accurately forms the basis for any realistic cost estimation of a property.
Neglecting these additional costs can significantly strain your budget. Therefore, plan from the outset to set aside a buffer of at least 10-15% of the purchase price for additional costs. This allows for a more relaxed approach to the entire purchase process. In the next step, we will take a closer look at the individual cost blocks.
Additional buying costs in detail: These fees must be planned for
When purchasing a property, additional costs inevitably arise that can influence your overall budget. The property transfer tax varies depending on the federal state and can amount to between 3.5% and 6.5% of the purchase price. This item alone can significantly increase your expenses. In addition, there are notary and land registry fees, which usually amount to around 1.5% to 2% of the purchase price. These fees are essential for the legally valid transfer of ownership. An accurate analysis of property prices always includes these additional costs.
If an estate agent is involved, additional commission fees arise. Depending on the agreement and region, these can be between 2.38% and 3.57% of the property price for the buyer. It is advisable to inquire about these cost points early on and include them in your cost estimate for the property. A detailed breakdown is as follows:
Property transfer tax: 3.5% - 6.5% of the purchase price
Notary fees: approx. 1.0% - 1.5% of the purchase price
Land registry fees: approx. 0.5% of the purchase price
Broker's commission (if applicable): 2.38% - 3.57% of the purchase price (buyer's share)
These percentages provide a good orientation for your calculation. However, not only these direct purchase-related costs are relevant; development costs can also play a part.
Development costs: When the plot is made ready for construction
An often underestimated cost factor in the estimation of a property's expenses is the development costs. These can range between 25,000 and 50,000 Euros for a 500 square metre plot. Development means connecting the property to public networks such as water, sewage, electricity, gas, and telecommunications. It also includes connection to the transport network, such as roads and footpaths. The valuation of properties must take this aspect into account.
The amount of development costs depends on several factors: the location of the property, the existing infrastructure, and the fee regulations of the respective municipality. On average, the costs per square metre are usually between 50 and 100 Euros. It is crucial to clarify before purchasing whether the property is already developed or what costs will still be incurred. You can obtain this information from the responsible municipality or city. An undeveloped property may appear cheaper in purchase price, but the subsequent development costs can quickly negate the savings. Therefore, a thorough inspection of the development status is a must.
The following points must be considered for development costs:
Connection to the water network
Connection to the sewage network
Electricity connection
Gas connection (if available/desired)
Telecommunications connections (telephone, internet)
Road connection and footpaths
Potential costs for street lighting
Once the development is clarified, the soil reference value comes into focus for the evaluation.
Bodenrichtwert als Basis: Understanding the value of land and soil
The standard land value is a key indicator for estimating the cost of a property. It indicates the average location value for properties within a specific zone and is expressed in euros per square metre. This value is determined by independent expert committees at least every two years based on the actual purchase prices achieved in the region. For an initial assessment of the property's value, the standard land value is essential.
To calculate the pure land value of a property, multiply the plot size in square metres by the current standard land value. However, be aware that the standard land value is an average. The actual market value of your specific property may vary from this, as individual features such as shape, orientation, buildability, and precise micro-location are not yet taken into account. Nevertheless, the standard land value provides an important guide. The standard land values can usually be accessed online through the standard land value information systems (BORIS) of the federal states or from the relevant cadastral offices. This transparency helps you better assess sellers' price expectations. A professional evaluation by Auctoa can provide additional assurance by precisely considering individual factors. Use our ImmoGPT chat for an initial assessment.
Thus, the standard land value is an important, but not the only factor in price determination. Other specific characteristics of the property also play a significant role.
Further value-influencing factors in land cost estimation
Besides the standard land value and development costs, numerous other factors influence the final cost estimation of a plot. The location is often the most crucial factor; plots in central areas or with good infrastructure are usually more expensive. The layout and topography of the plot also play a role – a well-proportioned, level plot is generally more valuable than a sloping plot or a very narrow strip. The market analysis for plots often shows significant price differences due to such characteristics.
Buildability, determined in the local development plan, is also critical. Are there restrictions regarding construction style, floor area ratio (FAR), or site coverage index (SCI)? Such requirements can significantly affect utility value and thus the price. The soil quality is also relevant. A soil survey, which can cost between 1,000 and 2,500 euros, provides information on load-bearing capacity and any legacy issues. These costs should be included in the overall consideration. A comprehensive valuation with helpful tools can provide clarity here.
Other factors include:
Micro-location: immediate surroundings, neighbourhood, noise pollution, view.
Macro-location: regional economic strength, transport connections, leisure opportunities.
Orientation of the plot (e.g., south-facing for gardens).
Existing tree stock or demolition costs for old buildings (which can amount to 10,000 to 25,000 euros).
Legal conditions: servitudes, rights of way.
A detailed analysis of these points is essential for a realistic cost estimate. Specific valuation methods are required to evaluate all these aspects correctly.
Methods for Price Determination: Comparative Value and Standard Land Value
For determining the land price and thus for a sound cost estimation of the property, mainly two methods are used. The comparative value method analyses actual purchase prices of similar properties in the nearby area. This method is very market-oriented but requires a sufficient number of comparable sales transactions. An appraiser uses anonymised collections of purchase prices from expert committees for this purpose. The steps of the evaluation are clearly defined here.
The second method is based on the previously mentioned standard land value. Here, the average price per square metre determined by expert committees is used as the basis. This value is then adjusted to the specific characteristics of the property to be evaluated (additions or deductions for special features). Both methods have their justification and are often used complementarily. For a precise cost estimation, it is important to understand the significance and limitations of both methods. Auctoa uses advanced AI-based analysis methods, which build on these established procedures, to enable you to obtain a quick and objective property evaluation via software.

The choice of the right method and its correct application are crucial for a reliable cost estimation. But what if the property is already built on?

Considering purchasing a plot with an existing building to demolish, you will face additional costs. The demolition costs for an average single-family house can range from 10,000 to 25,000 euros, depending on the size and construction method. These costs should definitely be included in your cost estimate for the plot. It is advisable to obtain several quotes from specialist firms for this. A professional assessment of the plot can provide clarity here.
Another important factor is potential contamination in the soil. Especially on land previously used commercially or older buildings, there may be pollutants in the ground. The costs for soil remediation are often significant and difficult to estimate in advance. A soil survey, which typically costs between 1,000 and 2,500 euros, can provide insights and help avoid unpleasant surprises. These potential additional costs should be considered when negotiating the purchase price. The meticulous examination for contamination and calculation of demolition costs are essential steps in estimating the cost of a developed plot to be redeveloped.
These specific costs can significantly impact the overall price. Accurate planning is therefore crucial here.
Conclusion: Precise cost estimation as the key to success
What are the notary fees when purchasing land?
The notary and land register fees typically amount to about 1.5% to 2% of the certified purchase price of the land. The exact amount is legally determined in the Court and Notary Fees Act (GNotKG).
Do I always have to pay development costs?
No, if you buy a fully developed property, these costs are usually included in the purchase price or have already been settled by the previous owner. However, with undeveloped or partially developed properties, these costs are incurred additionally. Always clarify the development status with the municipality before the purchase.
Is the standard land value the actual sale price?
No, the standard land value is an average value for a specific zone and serves as an orientation. The actual sale price may be higher or lower due to individual characteristics of the land (e.g., exact location, layout, buildability, contamination) and current market demand.
What role does a soil assessment play in cost estimation?
A soil assessment (costing approximately 1,000 - 2,500 euros) is important to examine the soil quality, load-bearing capacity, and potential contamination. The results can significantly impact the construction costs and thus the overall cost estimation of the land project.
Can I finance additional costs when purchasing land?
Generally, banks expect the additional purchase costs (about 10-15% of the purchase price) to be covered by personal capital. Financing these additional costs is rare and usually results in poorer credit terms.
