The topic briefly and concisely
Plan to budget an additional 15-20% of the purchase price for incidental costs (such as property transfer tax, notary, and estate agent).
Be sure to check the development plan with the responsible municipality before purchase to ensure buildability.
A soil survey (cost: €500-2,500) is essential to avoid costly risks such as contaminated sites or poor ground stability.
Purchasing a piece of land is more than just a financial transaction; it is the foundation for your future home or a strategic investment. However, without careful examination, risks lurking in the fine print and beneath the surface can blow your budget. A misjudgment of the building ground or overlooked entries in the development plan can quickly lead to additional costs exceeding €50,000. We guide you through the critical phases of land purchase, from precise cost calculations to final contract signing. This way, you make data-driven decisions and safeguard the value of your investment over the long term.
The true costs: Additional expenses up to 20% above the purchase price
The displayed purchase price is just the beginning of your investment. In fact, additional costs quickly add up to 15% to 20% of the pure land price. The real estate transfer tax alone is between 3.5% in Bavaria and 6.5% in Brandenburg or North Rhine-Westphalia, depending on the federal state. In addition, there are notary and land registry fees, which amount to about 1.5% to 2.0% of the purchase price. If a broker is involved, their commission can further increase the total costs by an additional 3.57% to 7.14%. Therefore, precise financial planning is essential. These figures show that incomplete budgeting can jeopardise the entire construction project even before the first spade is turned.
The foundation of your planning: Analyse the development plan and land registry
Before purchasing a property, it is essential to examine the legal framework. The development plan, which you can access at the local city planning office, is the most important document for this purpose. It definitively specifies what and how you are allowed to build—from the roof shape to the number of full storeys. The defined plot ratio (GRZ) and floor area ratio (GFZ) determine the maximum buildable area and are crucial for valuation. Additionally, the land register extract, available to interested buyers with a legitimate interest for €10 to €20, provides insights into ownership structures and potential encumbrances such as rights of way or land charges. A professional valuation report for your property summarises these analyses and reveals potential risks. Carefully reviewing these documents protects you from costly planning errors and ensures the buildability of your dream plot.
Beneath the Surface: Land Acquisition and Soil Surveys as Critical Cost Factors
A low purchase price can be deceptive if the plot is not developed. Costs for connecting to public networks such as water, electricity, and sewage can add up to between €15,000 and over €25,000. Therefore, clarify before purchasing whether the plot is considered "fee-exempt for development contributions" (ebf). Even more critical is the soil condition, which you can only reliably check through a soil survey. This survey costs between €500 and €2,500, but it can protect you from unpredictable risks such as contaminated sites or insufficient load-bearing capacity, the remediation of which often costs more than €100,000. Although there is no general legal obligation for a soil survey, it is indispensable for reputable planning. This is the only way to ensure that you can use your building land without unpleasant surprises.
The Path to Ownership: The 6 Essential Steps in Buying Property
The process of buying a property follows a clear structure that creates security for both parties. With the right preparation, you can navigate confidently through all phases. Here are the six key steps for successful acquisition:
Check financial framework: Determine your exact budget, including all additional costs of up to 20%.
Examine the property: Analyse development plans, land register extracts, contaminated land registers, and have a soil survey conducted.
Negotiate purchase price: Use the results of your assessments as data-driven arguments for price negotiation.
Obtain draft purchase contract: A notary prepares a draft contract, which you should review at least two weeks before the appointment.
Notarial certification: The purchase contract is signed in the presence of both parties and the notary, making it legally binding.
Payment and change of ownership: After paying the land transfer tax and the purchase price, the notary initiates the final entry in the land register.
A systematic approach according to this plan is the core of a successful real estate transaction. You can find a detailed overview in our guide to the key steps in buying a property.
Risk Management: How to Identify Hidden Burdens and Rights
Besides the obvious factors, invisible burdens can significantly reduce the value and usability of a property. Particularly, encumbrances that are not recorded in the land register but in the municipality's encumbrance register are a common risk. These include, for example, rights of way for neighbours or set-back distances that limit your own building freedom. Contaminated sites, that is, soil pollution from previous uses, can also lead to renovation costs in the six-figure range. A professional market analysis for property helps to identify these dangers early on. Do you have questions about specific risks related to your desired property? Our ImmoGPT chat is available for an initial, free assessment. This way, you minimise the risks when purchasing property and protect your investment.
The Notary Contract: The Legal Finale in Real Estate Purchase
The notary appointment is the highlight of the purchasing process, where the contract becomes legally binding. The notary acts as a neutral party and ensures that all legal requirements are met. The costs for their services and the land register entry are regulated by the Court and Notary Costs Act (GNotKG) and amount to approximately 1.5% to 2.0% of the purchase price. After notarisation, the notary applies for a priority notice in the land register, which secures your claim as a buyer. The final transfer of ownership only occurs after full payment of the purchase price and submission of the tax clearance certificate from the tax office. Ensure you receive the draft contract in good time to carefully review all clauses regarding the notary costs and obligations.

FAQ
What documents are crucial for buying property?
The most important documents are the current land register excerpt, the development plan, the extract from the building encumbrance register, and ideally a geotechnical soil report. These documents form the basis for a secure purchasing decision.
What does 'erschlossenes' plot mean?
A developed plot is connected to the public infrastructure. This includes connection to the road network, provision of water, electricity, and gas, as well as connection to the sewerage system. For an undeveloped plot, you must bear these additional costs.
How long does the entire process of purchasing a property take?
From the initial search to the final entry in the land register, several months may pass. After signing the notary contract, expect a period of about 2 to 3 months until all formalities, such as paying the land transfer tax and registering the title in the land register, are completed.
Can I include the incidental costs in the financing when purchasing a property?
Yes, most banks allow for the co-financing of incidental purchase costs. However, this requires very good creditworthiness, as the financing then exceeds 100% of the pure property value. Plan this early in your discussions with the bank.
What happens if contamination is found on the property?
If contaminated sites (soil pollution) are discovered, the owner is responsible for the remediation. The costs can be enormous. A soil survey before purchase is the best way to identify this risk. Additionally, a clause regarding cost coverage in the event of finding contaminated sites can be included in the purchase contract.
