My house is 110 sqm without a pool and the property tax, ENFIA, last year was €400. On top of that my council tax, paid through the electricity bill was about €200. It does depend where you live. The two major factors affecting both property tax and council tax are the size of the property and where it is located. Those figures are typical of a village in Crete. I would guess both would be a bit higher in the centre of cities like Chania or Heraklion. Other factors like whether it is detached or in the case of an an apartment which floor it is on or how many sides adjoin a road also have a small effect.
