i wouldn't rent a place full of someone's else's shite.
for one, how do i know the landlord will clear it all out if the former tenant ditches it there because they can't be bothered to take it with them?
for two, i'm renting the space. and i need every bit of it.
this isn't a childified house, it's a cluttered house.
if i went in with a letting agent or landlord and saw that i'd walk right back out, tbh.
we're private renters, btw.
it's fine if there's antoher tenant in the place when we view it, but if they are like something out of The Life Laundry, we give the place a swerve because we've been burned by tenants who don't take stuff with them and the landlord doesn't clear it out or landlords who use their rental property as extra storage place for their junk.
sorry, but you need to be ruthless.
do you really want to schlepp all that stuff around - box it, load it, etc.?
i try to keep the stuff to a min. for that very reason alone.
