In the afternoon I used Yahoo! to find more info on ‘renter’s insurance’.. And this is one of the many results I found:

Many individuals have full insurance on their primary residence and also cover the contents of their home. However, failing to have holiday home contents insurance for their vacation homes can leave them out in the cold in the event of a fire, storm or theft. Most holiday homes are usually empty for long periods and the chance of a break in increases with every day it sits empty. For this reason, many owners opt to rent their properties out when they are not using it, making it even more import

Not exactly what I was looking for, but still a interesting read.
