The countdown has begun for the rent increase rate to be applied to residential and commercial properties in September. The August inflation data, which determines the rent increase ceiling, will be announced by the Turkish Statistical Institute (TUIK) on Thursday, September 3, at 10:00 a.m.

The rent increase rate is calculated based on the 12-month average CPI data.

The 12-month average of the CPI is used as the basis for rent increase calculations. Therefore, the August inflation data to be announced by TUIK will clarify the upper limit that can be applied to rent contracts renewing in the September period.

EXPECTATION IS AT THE 30 PERCENT LEVEL

According to market expectations, if August inflation occurs at a monthly level of 1.44 percent, the September rent increase rate is expected to decline compared to the previous month. It is projected that the rate, which was at the 31.90 percent level last month, could drop to the 30 percent band in September.

The final rate will be determined after the August inflation data is announced.

In calculations made according to this scenario, the rent increase rate for the September 2026 period is expected to be approximately 30.98 percent. However, the final rate will be finalized with the announcement of the TUIK data.

The rent increase ceiling is closely monitored by tenants and landlords in the housing market.

The rate to be announced is important for tenants and landlords who will renew their rent contracts in September. The same data set is also taken into account for rent increases for commercial properties.

The September rent increase rate will be clarified on September 3.

Following TUIK's announcement of the inflation data, the official rent increase ceiling for September will also be shared with the public.
