I guess it's more am I being naive rather than AIBU.
I've not been a landlord for long, less than 2 years, so not really experienced. I had bought and done up the house just for me originally, then met my partner, we bought a place together and he encouraged me to rent my house.
I rent through an estates agents, but the tenants have my contact details from when I went over to show them how to drain a radiator.
A few days ago, they complained of a 'damp/sewage' smell that came from a specific drawer in the kitchen. I went over with my partner but we couldn't smell anything strongly. They thought there was a pipe leaking behind the wall but there are no pipes there.
My partner looked under the kitchen units and saw what might be mice droppings, so I asked if maybe the smell was from that. They said they had left the garden door open when it was hot and saw some mice come in but think they have gone now.
The tenants found some debris by the side of the kitchen extension (looks like their neighbours threw it into their garden) and think it might have blocked the damp proofing of the wall and could cause the smell. I think it might be dead mice, but to be safe I've arranged for someone to pick up the rubbish in the garden and for pest control to come and take a look.
So, I mentioned all this in passing to a friend and they are convinced I shouldn't have to pay for or even arrange for those things as 1. The mice came in through the tenants neglect and not through any holes in the property 2. The rubbish isn't mine to clear (or even the tenant's).
I'm arranging and paying for it all as I think it's just easier in the long run but she keeps saying I'm setting a bad precedent. Obviously if the neighbours throw more rubbish into the garden I'll tell the tenants to speak to them, but I don't see any harm in arranging for it to be cleared this time.
YABU - I shouldn't have sorted as it's the tenants responsibility
YANBU - I was right to sort it as a landlord
