So many problems ranging from flatmates doing the usual things like stealing things, to having food fights with my food despite me being poor, stealing my jacket and wallet, getting credit in my name, causing fire alarms to go off and hundreds of rooms evacuated and blaming me and wanting me to pay the fine and then steaing my tv when I moved out and that was just 1 property I lived at!
And having a flatmate who had a 2kw heater on 24/7, as well as putting thermostat to 35 degrees on gas in living room and refusing to pay his share of utilities, waking tenants up at 7am begging for cash, if you wanted a shower in morning and took more than 4 minutes he would knock on door shouting about how unfair you were to have a hour long shower meaning people had to go to class without one.
Property after that had a tenant who stole my food, letters, parcels and when confronted went on about how is loan was late and thus he was poor (but he could afford premium vodka and taxis to uni somehow) but never admitted it, one day I tricked him by saying I was going away for weekend when I was just getting a lift to uni, came back a hour later to find my brand new pan burned with opened packet of my food on side and even a bottle of drink of mine and even hearing him boast to other flatmates about what a soft touch I was, then he saw me enter and looked like he was shocked, he literally hid the bottle of drink and walked out the back door of building.
Then property after that made the mistake of being friend with a bipolar person but that wasn't the worst part, my direct flatmate in room next to me on one side was also mentally ill and had arguments with himself and on other side was a 247 party room as the tenant made spare keys and slept at his girlfriends every night, imagine 1-3 hours sleep a day for 8 months.
