The amount that you pay varies on the area that you live. If your property is registered with the council office then you will have a 5 digit number (sicil no), and this can be used to ask at the office to see how much you need to pay. I noticed an increase of up to about 4 lira on some properties. A rough estimate for a 2 bedroom apartment could be anywhere from 50 - 80 lira as it mostly depends on the area.
