First of all, it is utilities (Hausgeld): water supply and heating (9 Euro per 1 cubic meter per month), garbage collection (about 20 euros per month), electricity is always paid separately depending on the area and electricity consumption (about 50 euros per month for a two-bedroom apartment).
Utilities (hot and cold water, heating, gas, etc.) are paid according to the rates set every year. At the end of the year, recalculation is made according to the meter readings: if a larger volume of utility services was used, you will have to pay the difference; if you used less services than that paid for – a part of the amount will be refunded. If you rent an apartment, then utilities are paid by a tenant.
The annual tax on the ownership of real estate in Germany is about 0.1% to 0.4% and is calculated depending on several factors: the year of construction, the condition of the property, and other factors.
