We have an unpleasant busybody neighbour who complains about absolutely everything. The most recent example is her knocking on our door to tell us off for having a laundry dryer/horse visible from the outside. It's against the rules to leave them on the balcony, so we left ours in the doorway with the door open to the balcony, but inside.
She reported us to the building council and asked our other neighbour to have a word. Insane.
Anyway, we have proof that she is using her dining room to rent out for airbnb guests. This is strictly against our lease, and a serious breach of a lease is against almost all mortgage rules.
AIBU to report her to the mortgage company?
