Something easy to forget when buying. Not so much problem if its a flat in a building where there are others you know. Try insuring it with Intasure Staysure Towergate. Try and find local person to look round once a week if possible -pay them a little inducement maybe ! Maybe a barking dog gadget ? Where I am there are people who look after flats and houses while the owners are away. Some of these are English and do it to earn a crust -that ought not be difficult to arrange. Then a local estate agent -maybe the one you bought from or the people you bought from might know someone ?
