I think you are saying the same thing. Prices go up when more foreign visitors are there.
January to March is a good time to strike a deal. Money from last seasons tourism is drying up and suddenly that old house looks a whole lot less attractive than a big pile of Euros!
Pricing is a strange thing indeed in Corfu. But I suspect that this is as much because the market is quite young and prices demanded are based on hearsay from what others may have achieved to the last foreign buyer.
The Corfiots are only trying to realise the potential of their assests worth, same as any of us would on our homes. Interestingly though because most of the land and property are unincumbered with debt they can wait out until they like the offer on the table.
Despite my own bad experience of buying out there I dont think there is a conspiracy. Actually I have now succeeded in buying a piece of land and the building starts September and should be finished in May.
Now from friends building in Bulgaria i know a lot of purchases out there will never be built!
