This sounds really interesting to me. Can you send me more information on this. Any websites that go into this topic further?
There may be information in Greek on it but I don't think there will be anything in English.
We were told about it by Greek friends when we were about to buy our home. Although you pay purchase tax on houses, you can get a rebate on the first one, and it can be quite substantial. You may need to apply for the rebate before you sign the final purchase documents.
The agent we found our house through told us foreigners could not get the rebate so we almost didn't try. But a number of other people said we should be eligible as we had lived and worked here for several years. We decided to go and ask at our tax office ourselves.
They looked up the regulations and found that we were eligible. Unfortunately, now I think about it, it may only be for EU citizens living in Greece, not all foreigners. You have nothing to lose by asking though as I am not sure about that.
We were the first foreign couple (as opposed to a foreigner married to a Greek) to get it at our tax office.
From what I remember you need to prove how long you have been resident in Greece and possibly your tax office must not be the aliens one. You submit copies of your tax returns (I can't remember if it was 3 or 5 years). There were various other documents required, one of which we had to go to the Consul to get. I think we visited our tax office every day for about 10 days! It was definitely worth it though.
If you want to find out if you are eligible I suggest you go to your tax office with your residence permit and tax returns and information on the property or land you want to buy and ask them to check the regulations.
