The topic briefly and concisely
The incidental purchase costs (land transfer tax, notary, estate agent) can amount to up to 15% of the purchase price and offer significant savings potential.
A proactive maintenance strategy with annual reserves of around 1% of the property's value avoids costly emergency repairs.
Investments in energy efficiency can reduce ongoing costs by over 30% and are supported by government funding.
Deciding on a property is often one of the biggest financial milestones in life. However, the purchase price is not the only expense. A variety of cost factors – from property acquisition tax and maintenance to operating costs – can affect the profitability of your asset. Especially for heirs or private owners who need to make quick and informed decisions, transparent and efficient cost planning is crucial. This article shows you how to systematically reduce your property costs through data-driven analysis and strategic planning, thereby sustainably securing the value of your assets. We guide you through all phases of property ownership and uncover the greatest savings potentials.
Making Costs Transparent: The Basis for Any Optimisation
Efficient cost planning begins with complete transparency of all expenses. The total costs of a property can be divided into three main categories: acquisition costs, ongoing operational costs, and maintenance costs. Studies show that the prices for owner-occupied housing, including additional costs, increased by 68% between 2010 and 2022. This figure highlights the importance of accurate budgeting. A detailed cost overview is the foundation for controlling and specifically reducing expenses. Once all cost items are on the table, the real work begins: identifying the greatest savings potential.
Reduce acquisition costs: Achieve savings of over 15%
Even before actual ownership, you can set the course for efficient cost management. The incidental purchase costs often amount to 9% to 12% of the notarised purchase price. This sum, which is usually paid from equity, offers significant optimisation potential. The rate of real estate transfer tax alone varies between 3.5% and 6.5% depending on the federal state. For a purchase price of 400,000 euros, this difference can be up to 12,000 euros. Careful planning and negotiation can save thousands of euros here.
The essential acquisition-related costs include:
Real estate transfer tax: Depending on the federal state, 3.5% to 6.5% of the purchase price.
Notary and land registry costs: Usually about 1.5% to 2.0% of the purchase price.
Brokerage commission: Often between 3.57% and 7.14%, but since 2020, it is usually shared between buyer and seller.
Valuation costs: An optional but often sensible valuation report can cost between 500 and over 2,500 euros.
By carefully reviewing the notary and land registry costs and employing a clever negotiation strategy, these initial expenses can be significantly reduced. This early discipline lays the foundation for the financial health of your property in the coming years.
Mastering running costs: Reduce annual burden by 10-20%
The ongoing operating costs, often referred to as the "second rent", accumulate to a significant amount over the years. According to the Operating Costs Ordinance (BetrKV), these include property tax, water supply, sewage, heating, and insurance among others. On average, these costs amount to about €2.70 per square metre per month, which means over €2,900 per year for a 90-square metre apartment. Regularly reviewing supplier contracts can reduce annual expenses by 5-10%. A professional cost analysis helps identify all chargeable items and terminate inefficient contracts. In addition to the planned ongoing expenses, unforeseen maintenance costs often lurk, which can stretch any budget to its limits.
Strategically plan maintenance: Avoid up to 30% of repair costs
A reactive approach to repairs almost always leads to higher expenses. A proactive maintenance strategy is the key to long-term cost reduction. Experts recommend setting aside a maintenance reserve annually. The amount varies depending on the age of the property: For buildings older than 32 years, for example, 11.50 euros per square metre per year is recommended. For a 120-square-metre property, this corresponds to an annual reserve of 1,380 euros. Regular inspections can help identify major damage early and avoid costly emergency repairs.
Typical costly maintenance measures include:
Renewal of the roof covering (every 30-50 years)
Replacement of the heating system (every 15-25 years)
Renovation of windows and facade (every 20-40 years)
Modernization of electrical wiring (every 30-40 years)
A detailed valuation report for your home provides a solid basis for a long-term maintenance plan. Forward-thinking planning not only ensures the building's structure but also increases the value of your property.
Energy efficiency as a cost driver: sustainably halve heating costs
The greatest leverage for efficient cost design often lies in the energy condition of the building. Heating and hot water account for up to 80% of a household's energy consumption. Insulating the roof and façade can reduce energy costs by up to 30%. The replacement of outdated heating systems with modern alternatives such as heat pumps is also subsidised by the government. The KfW and the BAFA offer grants and loans that can cover up to 70% of the investment costs. Upgrading from efficiency class H to a better standard not only increases living comfort but also significantly enhances the property's value. An efficient property is not only cheaper to maintain but also achieves a better price when sold, which reduces costs in the long term.
Optimising sales costs: Maximising net proceeds
Even at the end of the ownership cycle, costs can arise that may reduce the profit. The brokerage commission, which can be up to 7.14% of the purchase price depending on the federal state, is one of the largest items. However, since a change in the law in 2020, these costs are fairly shared between the buyer and seller. Additionally, there are expenses for the creation of a legally required energy certificate, which range between 50 and 500 euros depending on the type. If a property is resold within ten years of purchase, a speculative tax may be due on the profit. A precise understanding of the brokerage costs when selling a house and strategic planning of the timing of the sale are crucial to maximize the net profit.

FAQ
What is the difference between maintenance and modernization?
Maintenance serves to preserve the original condition of the property by repairing wear-related damage. Modernization, on the other hand, improves the condition beyond the original standard, for example, through measures to increase energy efficiency or living comfort.
How does an Auctoa assessment help reduce costs?
A data-driven assessment from Auctoa provides an objective foundation for all financial decisions. It helps to determine the fair purchase or sale price, realistically assess renovation and maintenance needs, and precisely plan the budget for modernisations. This minimises the risk of bad investments.
Are the costs for an energy performance certificate apportionable?
No, the costs for issuing an energy performance certificate must be borne by the seller or landlord. They cannot be passed on to the buyer or tenant.
What costs does the seller incur when selling a house?
Typically, the seller incurs costs for the energy performance certificate, half of the estate agent's commission, potential costs for the removal of a mortgage from the land register, possibly an early repayment penalty from the bank, as well as capital gains tax.
What, according to the Operating Costs Ordinance (BetrKV), is included in the apportionable additional costs?
The 17 types of apportionable costs include, among others, property tax, costs for water/sewage, heating, elevator, street cleaning, waste disposal, garden maintenance, building cleaning, and certain insurances.
Can I negotiate notary fees?
No, notary fees in Germany are strictly regulated by the Court and Notary Costs Act (GNotKG) and are not negotiable. The amount is based on the purchase price of the property.
