Advice 2 : How much it costs to buy the island
A romantic dream to buy an island at first glance seems impossible. However, sometimes a private island can be bought for less than a Studio apartment on the outskirts of the city.
The size of the island
It is natural to assume that the cost of the island is greater, the greater its area. In fact, the cheapest in the world is the island of Gatun in the Panama area of about three thousand square meters, which can be purchased for around a million rubles. For a bit of private land, surrounded on all sides by water it is inexpensive.

Despite its high cost, this island can bring the owner an income almost immediately after purchase.
A dream to buy the island is not so feasible. In a world of many Islands from tiny and almost uninhabited until a huge, built up with hotels and one of them may be waiting for you.
