When buying an apartment in Mersin, it's important to consider not only the tapu price and the building's location but also the future monthly expenses. This is especially relevant for buyers in Mezitli, Tece , Tomük, Arpaçbahşiş, Çeşmeli, Erdemli, and Yenişehir: many buildings and residential complexes have a housing tax, which affects the real cost of living after the purchase. In May 2026, Turkey changed the rules governing how these payments are approved. For the Mersin real estate market, this isn't just abstract news; it's a practical matter when choosing an apartment.
What changed in 2026
On May 22, 2026, the official publication Resmî Gazete announced amendments to the legislation on condominiums and apartment building management. The essence of this change for the average buyer is simple: complex managers and administrations can no longer raise the aidat as freely as before. The relevant agency's materials explicitly state that the authority to determine the aidat amount is more closely tied to the decision of the owners, and that any increase above the yeniden değerleme oranı level requires the owners' approval.
This doesn't mean that apartment rents will stop rising. But now owners have more formal grounds to control the logic of increases, budgets, and expenditures. For those looking to buy an apartment in Mersin for living, vacationing, or long-term rental, this is an important signal: they need to consider not only the beautiful grounds of the complex but also the transparency of management.
Why is this important for Mersin?
The Mersin real estate market offers many "site"-style homes with swimming pools, security, elevators, generators, gardens, parking, and common areas. This format is especially common in coastal and rapidly developing areas, such as Tece , Tomük, Arpaçbahşiş, Çeşmeli, parts of Erdemli, and the new Mezitli neighborhoods. The more amenities within a complex, the higher the risk that buyers will underestimate the regular payments.
In practice, an attractively priced apartment in Mersin may not be as profitable if the building has a high Aidat, poor payment collection, or a complex budget. The new regulations do not eliminate maintenance costs, but they do make it especially important to thoroughly check the building's documentation and decision-making processes beforehand.
What is an aidat and what does it usually consist of?
Aidat is a monthly fee for common needs of a building or complex. It typically includes cleaning, lighting for common areas, elevator maintenance, security guards, pool and garden maintenance, and sometimes electricity and water for common areas. In large complexes in Mersin, the fee can vary significantly even among similar apartments, as the amenities and quality of management vary.
It's important not to confuse the aidat with individual utility bills. For example, water in Mersin is usually paid separately through the MESKİ line, and separate charges related to city tariffs may also be charged through the account. Therefore, when calculating a living budget in Mersin, it's best for buyers to consider three components: the aidat, individual utility bills, and any one-time household fees.
Practical section: what to check before buying an apartment in Mersin
- Find out the current amount of the aidat specifically for the selected house or site, and not for a neighboring property.
- Request the latest decisions of the general meeting of owners and understand who approved the amount and how.
- Check whether the seller has outstanding debts under the Aidat and whether there are any disputed charges.
- Ask what services are actually included in the payment: swimming pool, security, generator, elevators, garden, cleaning, parking.
- Find out if there have been any unscheduled charges for repairs, facades, pumps, elevators, or landscaping in the last 12 months.
- Understand how much the building is permanently occupied: in buildings with a large number of seasonal apartments, the burden on paying owners may be greater.
- Check whether the data level corresponds to the condition of the complex, and not just to the seller's promises.
How buyers can use the new rules to their advantage
If you're looking for an apartment in Mersin in 2026, inquire about the price as carefully as you do about the sea view or the distance to the beach. New regulations give owners a greater say in approving price increases, meaning buyers will value buildings with clear management and good internal communications.
For Mezitli and Yenişehir, this is often a question of the quality of permanent residence. For Tece , Tomük, Arpaçbahşış, and Çeşmeli, it's also a question of seasonality, with some apartments only occupied in the summer. For Erdemli and coastal locations in general, it's important to understand how stable the building's expenses are year-round. Ultimately, when buying an apartment in Mersin, the winner isn't the one who finds the lowest price, but the one who understands the full monthly occupancy in advance.
Conclusion for the buyer
The new aidat rules are a good reason to more thoroughly inspect not only the apartment but the building itself. Living in Mersin, this directly impacts comfort, predictability of expenses, and peace of mind after the transaction. If the property is located in a modern complex with infrastructure, the aidat issue becomes part of the property inspection, along with the documents, location, and condition of the building.
