After reading this you will think hundred times before renting out your flat to a tenant. Graham Holland from Maidstone, Kent, the owner of the flat, was shocked as he visited his flat after almost a decade to find that his house was in a huge mess - shambles, in fact. The house was so dirty that he couldn't even see the floor, which was covered with empty beer cans, cigarette packs, food wrappers, polythene bags and more junk. Holland was so shocked that he could not even believe that any person could live in such a mess and that too for years. Not willing to pay the hike in the rent, tenant Michael Grant, 68, had moved out of the flat after living there for 12 years. But what he had left behind, was huge clutter. Daily Mail revealed, "Mr Holland said that he was in utter shock and disbelief that anybody could live in such a mess." Holland's wife, Nicole Holland, 56, had bought this one-bedroom flat 30 years ago and had been renting it out to several people before Grant started living there. Since Grant had started living in the flat, Holland was unable to visit his own property. Grant was unwilling to let anybody in and had turned irritable. Holland was bewildered with his behaviour but he didn't bother much as he paid the rent on time. They had always tried to keep the flat clean and tidy so that it looks good when new tenants move in. But what they received in return, was utterly disgusting. Holland and his wife had to clear the mess themselves and it took them over four days to dump the mess, even as cleaning was another task. The tenant had also left the washroom in a bad condition with the toilet overflowing with sewage and food strewn across. If this was not enough, the couple had to pay roughly \u00a310,000 to repair the damage done to their flat. And to add to the disbelief, the tenant was not at all ashamed and accepted the fact that he was the one who caused the mess.
