On the subject of emotional attachment to homes, they may well be mere bricks and mortar but I don't think it's unusual for such feelings, a home is for many a place of memories. My children often wax lyrical about the two houses they grew up in, particularly the last one where we lived for 19 years. In fact when we announced we were selling it my younger son, very tongue in cheek, wailed "don't do it think of the children!" both having flown the nest for at least 5 years
and although he was joking when he said that, it has surprised and maybe I didn't bargain for it that they had quite deep attachments to our last house in particular.
I also have my late brother's flat I rent out, on occasions at "mates rates" to our children. I have been lucky to have had some very good tenants and always try to be an equally good landlord in fulfilling my obligations set out in the rental agreement drawn up by the management company. I imagine it must be devastating to find your property wilfully trashed, commiserations to those posters who have experienced that.
I know not all landlords honour their side of the agreement, my children have been tenants and had some ghastly landlords. When my son was at university he rented a house with other students and the landlord, whilst they were in situ, tried to embark on extending the back of the house without consulting them, they only found out when his builders arrived one Monday morning with bulldozers. Only after a strongly worded solicitor's letter did the landlord back off, he knew perfectly well what he was proposing to do was illegal, but thought they'd put up with it because they were young and naive.
