When we moved in the house had been rented out to a family of 5 adults and two dogs. They clearly weren't happy about the house being sold.
When we got the keys, five days after the tenants left, we came in to a filthy house. Balls of dog hair everywhere, huge spiderwebs and spiders, floors thick in dust and food splatters all over the kitchen. They also left garlic cloves in the extractor fans (that were also full of dust), took every single light bulb, left gauges in all the lovely wooden floors, took tiles out of the fire place, left a huge heavy wardrobe upstairs, an old stained mattress, a table missing two legs, dusty moth eaten old curtains, the dishwasher was blocked with old food and full of mouldy plates and cutlery -full on white fluffy mound, the kitchen was so dirty I had to buy a wallpaper scraper to get rid of the grease. Fucking disgusting it was.
I called the estate agent who assured me that the vendor had been in and checked the property after the tenants had left and had paid for a cleaner too. I sent photos to her and copied in our solicitor. The estate agent called me back within minutes of receiving the email and I honestly think she was angrier than I was. We managed to get the vendor to pay for a deep clean of the house and pay for a night in a hotel for us.
I put the wardrobe on a Facebook selling site and the woman who had lived here commented saying that what I was doing was theft and told people not to buy it, then sent me abusive messages. I went out the next day and came back after a few hours to find that the wardrobe had gone. No break in, they clearly had a set of keys still. Called the estate agent again and the police. Apparently they had been waiting for me to leave, sat in their car parked down the road. They thought it was ok because it was their property and they used a key to get in. Couldn't quite understand that it may have once belonged to them but their "property" was now taking up space in our property. Locks were changed immediately! Which we were planning on doing but a few days later.
I saw the mum and one of her sons in our local shop and she hid from me!
