I may be overthinking things, and I'm not planning on selling so I'm not looking at it from that point of view...
Mid town house. Next door moved out nearly two years ago, it was rented and now it is for sale. Haven't seen anyone coming or going.
Their hedges are now about 20 feet tall at the back of their garden (my side is a fence so no issue), and about ten feet at the front. Their downstairs extension is completely covered in ivy, as is one of their upstairs windows. The garden is completely overgrown. The house is completely empty.
AIBU to worry about the overgrowth, possible vermin, damp; or any other effects of the house not being occupied that I have yet to panic about? Or will it just be fine and I should enjoy the peace?
