If you have decided which island you wish to buy, check the weather! On the world wide web, there are many websites with weather statistics for every country (such as www.weather.com etc.). These weather statistics include wind, amount of sunshine hours throughout the year and humidity. If you like what you see, you should invest in that area. If you inspect the island, it is very advisable to do so during the worst month (weather-wise), so that in future, you will not be disappointed.
Climate conditions are also important for investors. Only islands which have moderate climates enjoy the best growth in value. With increasingly severe weather conditions such as tornadoes, hurricanes and tsunamis, this checkpoint should be looked at very carefully.
