Many buyers look at common costs almost as an afterthought. The focus usually stays on purchase price, monthly utilities and achievable rent , while the financial operation of the building itself receives far less attention. In practice, however, common costs often reveal a great deal about how a condominium is managed, how financially stable it is and what owners may eventually face later. In Budapest, where many apartment buildings are decades old, the state of a building’s finances are crucially important to a buildings upkeep. They can also reveal how well the building has been maintained, whether reserves are being accumulated and how prepared the condominium is for future repairs.
What Common Costs Actually Cover
The common cost (közös költség) is the regular contribution owners pay toward the operation and maintenance of the condominium.
Depending on the building, this may include:
- staircase lighting and cleaning,
- elevator operation,
- waste collection,
- building insurance,
- common utility costs,
- garden or courtyard maintenance,
- accounting and banking expenses,
- the common representative’s fee,
- and ongoing maintenance or renovation reserves.
In some buildings, central heating systems, concierge services or underground garages also significantly increase operating costs.
The exact structure always depends on the condominium itself. A newly built building with modern systems may have very different operating expenses from an older inner-city property where maintenance needs are becoming more frequent.
In Budapest, average common costs are often around 130–180 forints per square metre without water charges and roughly 200–250 forints with water included, although the real figure can vary substantially depending on the building’s condition and services.
Why Common Costs Vary So Much Between Buildings
Two apartments with similar sizes and locations can still have very different common costs.
Older buildings often require more maintenance because aging roofs, façades, plumbing systems and electrical infrastructure gradually become more expensive to maintain. Buildings with elevators, larger common areas or central heating systems also tend to have higher operating expenses.
Newer developments may appear more efficient at first, but concierge services, underground garages, gyms, swimming pools, security systems and higher service expectations can also increase monthly costs significantly.
In some condominiums, monthly owner contributions remain artificially low because maintenance work is continuously postponed or reserve accumulation remains insufficient. Many buyers only discover the consequences later, after larger renovation projects or extraordinary contributions suddenly become unavoidable. This is one reason low common costs do not automatically mean a well-prepared building.
How Common Costs Are Usually Calculated
In most buildings, common costs are allocated according to ownership share (tulajdoni hányad), unless the condominium rules use another method.
In practice, this means larger apartments usually contribute more because they represent a larger ownership percentage within the building.
At the same time, condominiums may use different calculation methods depending on the type of expense involved. Some costs may be divided according to apartment size, while others may rely on individual consumption meters or separate allocation rules defined in the SZMSZ (Szervezeti és Működési Szabályzat).
For buyers and investors, this matters because two otherwise similar apartments may still carry very different long-term ownership costs depending on how the condominium operates.
Why Maintenance Planning Matters More In Older Buildings
Some buildings only deal with problems after they become urgent. Others gradually build reserves and handle maintenance before larger failures appear. There is a major difference between these two approaches over time.
As renovation cost continue rising across Budapest, many condominiums are discovering that delayed maintenance usually becomes more expensive later. A roof repair postponed for several years may later require full structural replacement. Aging plumbing systems can create repeated emergency repair costs before complete modernization finally becomes unavoidable. In some older buildings, owners can go years without major financial pressure, then suddenly face several expensive projects almost at once. This is why experienced buyers increasingly look beyond the monthly common cost itself and pay more attention to the overall condition and reserve position of the condominium.
The Owner Remains Responsible
In rental apartments, tenants often pay the monthly common cost directly as part of the rental agreement. Legally, however, the condominium’s relationship remains with the owner. If the tenant stops paying, the condominium may still pursue the owner for the outstanding amount. This distinction becomes particularly important for investors managing multiple apartments , because unpaid common costs can eventually create legal and financial complications even if the problem originally began with the tenant.
Buyers should also check whether the apartment carries outstanding common-cost debt, as condominium rules may allow the building to pursue certain arrears even after ownership changes.
What Happens When Owners Do Not Pay?
Unpaid common costs affect the entire condominium community because the building still needs to cover operating expenses regardless of whether every owner contributes on time. Most condominiums first attempt to resolve the issue through payment reminders or instalment agreements. If this does not work, the matter may proceed into legal collection procedures.
Under Hungarian condominium law, longer-term arrears can eventually result in:
- payment orders,
- enforcement procedures,
- and even mortgage registration against the owner’s property interest in the building.
Why Lower Common Costs Do Not Always Mean Lower Long-Term Costs
In Budapest, buyers often compare common costs mainly by asking which apartment appears cheaper to operate each month. But the monthly amount alone rarely tells the full story.
A building with slightly higher common costs may actually be in a stronger long-term position if:
- maintenance is performed regularly,
- renovation reserves are being accumulated,
- and long-term building management is functioning properly.
Meanwhile, unusually low common costs can sometimes signal deferred maintenance, limited reserves or future pressure that has simply not appeared yet.
Over time, the quality of the building’s financial management often affects ownership costs just as much as the apartment itself.
