An increasing number of Germans are voicing concerns about receiving an inadequate pension, prompting a widespread search for alternative income streams to secure their financial future in retirement. Among the options gaining traction is the seemingly lucrative prospect of renting out apartments within multi-unit residential buildings. This strategy is often bolstered by the observation that many wealthy individuals and family offices have consistently invested in real estate for years, suggesting a reliable path to good returns. However, recent findings from a survey conducted by the German Owners’ Association (Haus & Grund) paint a less optimistic picture, revealing that a significant portion of private landlords are operating at a mere break-even point, or even incurring losses with their rental properties. This raises a critical question: in the current economic climate, characterized by rent regulations, elevated property prices, and rising interest rates, how genuinely profitable is it to manage a multi-unit apartment building? This analysis delves into the complexities, presenting three illustrative financial scenarios and highlighting a costly pitfall that prospective buyers should diligently avoid.

The Pitfall of Personal Preference: Prioritizing "Good Enough" Over Prime Locations

A fundamental error that many prospective real estate investors make, according to Jürgen Michael Schick, CEO of Schick Immobilien in Berlin and honorary president of the IVD (German Association of Real Estate Agents), is using their own personal preferences as the primary benchmark for evaluating a property. "If individuals ask themselves whether they would personally enjoy living there, if their children might reside there in the future, and if they personally like the location, they are already making a costly mistake," Schick explains. This subjective approach often leads buyers to overpay for properties in desirable neighborhoods or to acquire assets that are more expensive than necessary.

Schick emphasizes that for investment purposes, a "simple to mid-range building in a middle-tier location is sufficient to achieve a good return. You typically pay top prices for top locations." This distinction between personal appeal and investment logic is crucial. Real estate investors should focus on the economic fundamentals of a property and its location, rather than its aesthetic or lifestyle desirability for themselves.

Gerald Hörhan, a prominent real estate investor who styles himself as an "Investment Punk," echoes this sentiment, warning that "many investors prioritize prestige and aesthetics over economic viability." He advocates for smaller, simpler apartments in functional areas, as these typically offer predictable rental income, robust demand, and manageable risks – the core elements of a sound investment strategy.

Unpacking the Numbers: Potential Returns from Rental Apartment Buildings

To provide a clearer understanding of the financial landscape, Handelsblatt, with the expert input of Schick and Hörhan, has developed three model calculations for acquiring and subsequently renting out multi-unit apartment buildings. These hypothetical scenarios are based on properties located in German cities that are not among the largest metropolises. The initial purchase price for each property is set at one million euros, with an additional ten percent allocated for ancillary costs, including notary fees, land registry entries, and broker commissions.

The projected annual net cold rent for these buildings varies across the three scenarios: €44,000, €55,000, and €61,000. These figures reflect different cost structures. In the first scenario, the purchase price, including all ancillary costs, equates to 25 times the annual net cold rent. In the second, this multiple is 20, and in the third, it is 18. For the purpose of detailed analysis, this article will focus on the calculations for the multiple of 20, which is considered representative of conditions in most medium-sized German cities. The financial outcomes for the other two multiples can be observed in accompanying graphics.

It is essential to note that from the net cold rent, landlords are responsible for covering maintenance and repair costs. Therefore, the model incorporates annual management expenses of €11,000, which cannot be passed on to tenants. Potential value appreciation from rising rental income and specific tax depreciation allowances for new buildings are not factored into these calculations, as they are not universally applicable.

A ten-year timeframe has been chosen for this analysis. While the properties may not be fully paid off within this period, ten years marks the end of the speculation period for real estate in Germany, meaning any profit realized from a sale would be tax-free.

Model Calculation 1: The Impact of €200,000 in Equity

This first model assumes the buyer contributes €200,000 in personal capital, necessitating a loan of approximately €900,000. The calculation is based on an annual interest rate of 3.5% and an annual repayment (tilgung) rate of 1.5%.

Consequently, in the initial ten years, the buyer must allocate €31,500 annually for interest payments and an additional €13,500 for principal repayment. While the principal repayment contributes to the property’s equity, it represents a significant outflow of cash.

The property generates a net annual rent of €55,000. After deducting the €11,000 in non-recoverable costs, this leaves a net annual profit of €44,000. Subtracting the annual interest burden of €31,500 from this net profit results in a surplus of €12,500. This would translate to a return on equity of approximately 6.25%.

However, if a more conservative approach is taken, including the €13,500 annual principal repayment, the landlord’s total annual expenses rise to €45,000. In this scenario, over the first ten years, the buyer would effectively be out of pocket in terms of immediate cash flow, despite building equity in the property, which might only be realized upon sale.

Model Calculation 2: Increased Equity and its Financial Implications (€300,000)

In this second model, we again consider a multi-unit building with a net annual rent of €55,000 for a purchase price of €1.1 million (including ancillary costs) in a secondary city, with loan interest at 3.5% and principal repayment at 1.5%. This time, the buyer contributes €300,000 in equity, requiring a loan of €800,000.

The net annual profit remains €44,000. The interest costs are now reduced to €28,000 annually. This leaves a profit of €16,000. Calculated against the €300,000 equity, this yields a return on equity of approximately 5.33%.

When the €12,000 annual principal repayment is factored in, the total annual expenses increase. After deducting these costs from the €44,000 net profit, approximately €4,000 would remain. This would represent a cash flow return on equity of about 1.33%.

Model Calculation 3: Maximizing Equity and its Impact on Returns (€400,000)

For the third example, we maintain the scenario of a multi-unit building in a secondary city with ancillary costs bringing the total to €1.1 million, and the loan terms of 1.5% repayment and 3.5% interest. In this case, the buyer invests €400,000 in equity, requiring a loan of €700,000.

Assuming the same €55,000 net annual rent and €44,000 net profit, the annual interest costs are now €24,500. This leaves a profit of €19,500. On an equity of €400,000, this translates to a return on equity of approximately 4.9%.

Again, considering the principal repayment of €10,500 annually, the total annual expenses increase. After subtracting these costs from the net profit, approximately €9,000 remains. This results in a cash flow return on equity of around 2.25%.

The Trade-off: Security vs. Returns in Real Estate Investment

Jürgen Michael Schick highlights that "the amount of equity plays a significant role." As the proportion of personal capital invested increases, the return on equity, when viewed solely from the perspective of interest expenses, appears to decrease. However, a higher equity stake concurrently reduces the buyer’s overall risk.

"Therefore, individuals investing in a multi-unit apartment building must consider whether their priority is to enhance security or to optimize returns," Schick advises. For affluent buyers, leveraging a substantial portion of debt financing can be an attractive strategy, as they are typically better positioned to manage higher loan burdens.

However, it is crucial to temper expectations. As author and asset manager Gerd Kommer points out, "Most Germans have overly optimistic perceptions of the total return from real estate and equally unrealistic views of the actual risks." He estimates that for debt-free properties, long-term real returns of 2% to 3.5% per year after taxes and costs are realistic. When debt financing is involved, the net return is further diminished. Kommer cautions that the exceptionally high returns experienced during the "golden era of German residential real estate" from 2012 to 2021 are not representative of historical averages and are unlikely to be sustained in the long term.

The current market environment, marked by regulatory pressures on landlords, the high cost of property acquisition, and increased borrowing costs, presents a complex challenge for aspiring real estate investors. While property ownership can offer a path to long-term wealth accumulation and a supplementary retirement income, it is not a guaranteed or risk-free endeavor. A thorough understanding of the financial dynamics, a realistic assessment of potential returns and risks, and a disciplined approach to investment decisions are paramount to navigating this landscape successfully and avoiding costly missteps. The pursuit of pension security through rental income requires meticulous planning and a clear-eyed view of the market realities.
