It took me six months, a court case (with solicitor) and the court sheriff and a locksmith to finally get her out- almost a year from the first 'you're out' notice (and that was 3 months after she stopped paying the rent) until she was off the property...
Then I had the joy of cleanup and repairs- a complete new kitchen and bathroom, AFTER the shared wall and floor/joists were replaced (she fitted a new shower head herself and it leaked into the wall cavity and rotted out the wall and floor), TWO dumptrucks of rubbish from the yards, plus another from inside the house (she became a hoarder after she lost her job as a teacher- the bedrooms were all completely filled up to the roof, she was sleeping in the lounge on top of a pile of rubbish- in a gap barely big enough to fit between it and the roof) it needed all new paint (painted the walls PURPLE-urgh) and all new carpets throughout...
Plus I had to have electrical repairs done and an inspection as she had been stealing electricity and hardwired past the fusebox...
In all it cost well over 20k- which was more than I had gotten from it in rent...
A net loss...
