Somewhere over the rainbow.
It is a dream that a lot of people in Northern Europe have, normally on the Monday morning commute to work; move to the sun for a better life...
Greece is a member of the European Community, so if you are coming from another member state it is quite easy to move to Greece. As a EU resident, you can have your pension paid here, you can also drive on a EU driving license, even work here and transfer to the Greek Income Tax system. Most people that move to this area buy a property, either as a summer home or a permanent residence, the good news is that it is easy to do.
All buyers must have a Greek tax number. This is issued by tax offices, it is free and issued immediately. Foreigners buying property in Greece must show where the money has come from. Anyone who buys property and does not already file income taxes in Greece must do so in the following year to declare the amount spent in purchasing the property, on taxes and other pertinent fees. If the buyer cannot justify the amount of money they have spent, the Greek tax authorities will say it is unreported income and the buyer will have to pay income tax. The buyer also pays the transfer tax, it must be paid before the purchase, the same with property tax which depends on the value of the property. Buyers may also be subject to pay an annual tax. The buyer may qualify for a tax exemption if it is their first home. A notary public fee has to be paid by the buyer. All real-estate transactions must be carried out before a Notary and must go on public record in the appropriate land registry. The Notary will not authorise any sale without making sure that all the appropriate tax papers and deeds are in order. Always use a Lawyer to make sure everything is in order. The lawyer and notary fees are generally about 1-2 percent of the amount listed in the notarial deed of sale. If you are coming from another EU country you don't have to pay income duty on your household goods, so bringing your belongings with you is also easy.

Since most Greeks have medical insurance for all health care, it is advisable to do the same, even though basic health care is available at the local Health Centre for free. This service is available to visitors who have filled the E111 in the UK or equivalent papers. The common practice in Greece if the illness or injury isn't too serious is to go to the local pharmacist, who can give advice and certain drugs, even antibiotics.

It is even possible to bring your pets into Greece, as long as they have all the proper inoculations and paperwork. Micro-chipping of dogs is becoming law very soon in Greece, so it is best to have this done before coming. There are different risks here for your pets from ticks and flies, so it is best to seek professional advice about protecting your pets.
Some of the bigger supermarkets offer a good range of foreign foods, but sometimes it takes a while to find what you need, but the shop owners are always more than happy to help, if you try and describe what it is you're looking for. Most people shop on a daily basis, and a lot of local produce is for sale, this make the vegetables seasonal as there is very little imported.
But before you give up the day job, you have to remember that this is Greece and there will be drawbacks, and sometimes it is hard if you don't speak the language, but if you speak to most ex-pats here, they don't regret it for a moment, and don't want to go back home.
P.S. There is of course, satellite TV available!
