An apartment in Berlin is an important part of many people’s wealth. However, rising management costs, necessary building renovations, and potential special charges can pose significant financial challenges for owners. When are additional investments worthwhile, and at what point should one consider selling?
Anyone who owns a residential property is not only responsible for their own four walls. As a member of a condominium association (WEG), they also contribute to the costs of the entire building. This includes ongoing management as well as repairs, maintenance, and major renovations.
As long as monthly expenses remain manageable, these obligations are often taken for granted. However, if house payments increase, the maintenance reserve falls short, or an extensive renovation is to be decided upon, the financial situation may change significantly.
Especially in Berlin, where numerous condominiums are located in older apartment buildings, it is therefore worthwhile taking a closer look at the structural condition and the economic development of the condominium.
Why house fees can become a burden for owners
The monthly house fee serves to finance the ongoing costs of a condominium community. These include, for example, water, heating, building insurance, cleaning, caretaker services, and administrative costs. In addition, there are contributions to the maintenance reserve, from which future repairs and maintenance measures are to be financed.
The amount of the house fee depends on the building, its technical equipment, ongoing contracts, and the approved business plan. If energy prices, insurance premiums, or the costs for services increase, this can directly affect the monthly payments.
It is particularly important for landlords to distinguish between depreciable and non-depreciable costs. While certain operating costs can be passed on to the tenants under a corresponding lease agreement, for example, administrative costs and the contributions to the maintenance reserve must be borne by the owner himself.
Self-users are also affected. They bear all the costs associated with their apartment themselves and must additionally expect that major repairs to the common property will require additional payments.
However, an increasing house mortgage is not automatically a sign of poorly managed property. It can also be an expression of forward-looking economic planning, for example when higher reserves are created to better finance future renovations.
Special levy: When suddenly several thousand euros become due
It becomes particularly unpleasant for owners when major renovations are necessary and the existing maintenance reserve is not sufficient. In such cases, the property association can decide to impose a special levy to raise the missing funds.
This applies, for example, to the renovation of a roof, the renovation of a facade, the replacement of a heating system, or extensive work on balconies and pipes.
The extent to which such a measure burdens the individual owner depends on the total costs, the available reserve, and the applicable cost allocation key.
An example of calculation from a homeowners association
Suppose a Berlin apartment building with twelve apartments needs extensive roof renovation. The estimated costs amount to 240,000 euros. 96,000 euros can be financed from the existing maintenance reserve, leaving the property owners to raise another 144,000 euros.
In the case of a simplified uniform distribution to twelve apartments, each owner would have to contribute an additional 12,000 euros. In reality, the cost distribution is based on the applicable legal regulations and agreements, often based on the co-ownership shares.
For some owners, such a payment is easily possible. Others have to draw on reserves or take out additional financing. The situation can become particularly burdensome if several large-scale measures are required within a few years.
The figures are purely for illustration purposes and do not represent an estimate of the actual renovation costs of a specific building.
What renovations could be undertaken in the coming years?
Many Berlin apartment buildings were built several decades ago. Accordingly, their state of modernization varies widely. While some homeowners associations have already invested extensively in the building’s infrastructure, other important measures still lie ahead.
In addition to classic maintenance work on the roof, facade or pipes, energy-efficient renovations are becoming increasingly important.
These include, for example:
- Improvements in thermal insulation,
- the replacement of outdated heating technology or
- Measures to reduce energy consumption.
The requirements in a specific case depend, among other things, on the building, the existing technology, and the applicable legal regulations. Not every older heating system needs to be replaced immediately, and not every energy-saving measure is equally economical for every building.
Owners should therefore clarify early on what work is actually necessary, what costs are expected to arise, and what funding opportunities are available, if any.
Good planning can prevent several measures from being carried out in an uncoordinated manner, thereby avoiding unnecessary additional costs.
What owners should know about their WEG
Whether a residential property remains economically attractive in the long term depends not only on the condition of the individual apartment, but also on how well the entire community of owners is organized.
A look at the annual accounts, business plans and decision-making documents can provide important clues. Particularly revealing are the amount of the maintenance reserve, already approved renovations, and the question of whether major repairs have been necessary regularly in recent years.
The minutes of the owners' meetings also deserve attention. If there are repeated mentions of damage to the building structure, necessary renovations, or financing problems, owners should take this information seriously.
A high maintenance reserve is not automatically sufficient, and a low reserve is not necessarily problematic. What matters is whether the available funds match the actual condition of the building and the foreseeable measures to be taken.
Do you know what investments are planned in your building?
Check the current financial plan, the amount of the maintenance reserve, and the resolutions of the last owners' meetings. Especially before making major financial decisions, it is worth considering the development of the entire community of owners.
Do you know what investments are planned in your building?
When high investments are expected, some owners ask themselves whether they should keep their apartment or rather sell it.
Selling a property before renovation can be beneficial if the necessary funds are not available or the owners want to use their capital differently in the future. However, it should be taken into account that prospective buyers will also need to consider the building’s structural condition and any foreseeable investments that might be required to meet their price expectations.
An upcoming roof renovation or a special levy already approved does not disappear economically by selling the apartment. Rather, in individual cases it must be clarified which financial obligations remain with the previous owner and which pass to the buyer. In particular, the decisions of the property association, the timing of payments, and the agreements in the purchase contract play a role.
Conversely, it can be advantageous to have necessary renovations carried out first. A technically modernized and well-maintained building can be more attractive to buyers and have a positive effect on the property value.
However, it is not possible to answer unequivocally whether the investment will actually pay off through a higher selling price. For this, the estimated costs and the potential sales revenue before and after the renovation must be compared with each other.
How is the Berlin market for condominiums developing?
The decision on a possible sale also depends on how the Berlin real estate market develops.
According to the Property Valuation Committee in Berlin Market activity has increased in 2025 compared to the previous year. Sales and cash flow increased in many sub-markets, while prices remained mostly stable.
Also the IVD Berlin-Brandenburg In October 2026, it reported an increase in the number of residential sales. In the first three quarters, around five percent more condominiums were sold than in the corresponding period the previous year. The average asking price was around 5,070 euros per square meter, which was approximately the same as the previous year.
These figures show that apartments in Berlin continue to be traded. However, they do not mean that every apartment can be sold easily or at a certain price. Location, condition, energy efficiency, existing tenancy arrangements, and the economic situation of the condominium all significantly influence the achievable purchase price.
Therefore, in the case of apartments in buildings that require renovation, a individual market valuation important.
When is keeping the apartment the better decision?
Not every upcoming renovation is a good reason to sell. On the contrary: Those who want to keep their property for the long term and have sufficient financial resources can benefit from well-planned modernization.
A renewed heating system, a renovated roof or a restored facade can help maintain the building’s value and reduce future repair risks. Energy improvements can also reduce ongoing consumption costs, even if not every measure is immediately financially worthwhile.
For landlords, renting out an apartment can generate regular income over the long term. Self-occupants, in turn, benefit directly from improved living comfort and a building that is more technically reliable.
The decision should therefore not depend solely on the amount of a single special levy. What is essential is rather how the entire property is expected to develop in the coming years and what financial resources the owner has at his disposal.
