We made the mistake of living next to our landlords who thought that "managing the property" meant anything they say goes. Big country house(them), barn conversion with seperate drive and garden partly seperated by hedge (us). Examples of behaviour included;
1. Moving my bike tyre off our drive and hanging it on front door.
2. Moving my bike tyre off said drive again,hanging it on door, complete with message suggesting i place tyre in our shed and should not ignore this message.
3. Snooping around our bedrooms when they read the meter in the kitchen.
4. Cutting grass, weeding our garden without asking if its ok first.
5. Taking our house keys when i left them in the shed while out riding for 30 minutes. We all do this once, but I might explain, we lived in the middle of no where, my wife was in, and crashing around in the kitchen. They then did not return keys for 4 hrs, no doubt to teach us a lesson as we looked high and low for them, although i knew it could only have been them.
6. Making up stuff or wrongly interpreting contractual tenacy obligations
7. On at least one occasion owned up to entering property without prior arrangement.
So, nothing major, but after 6 months we'd had enough of being watched and our privacy invaded. The only reason we did not confront them was due to organising in double quick time our wedding which was stressful enough.
Was pleasing to see that it took them a further 9 months to rent the property at a vastly reduced rental amount.
