Well good luck to you all, hope those who want to be in before Christmas are in, just keep some money aside spare... Since completing in the middle of last month I have had to;
1) Replace front door (they had wedged a piece of cardboard in to hold the lock/ in place), £860 for a composite front door
2) Have fusebox upgraded to latest version, it had the original fusebox (1970's) in there and awful wiring.
3) Fix several bodge-jobs both electrically and plumbing related by the previous owners being DIY fans, but DIY idiots more like.
4) Replace a toilet upstairs that they left with a broken flusher
5) Empty a freezer full of frozen food that they left inexplicably.
6) Have the oven cleaned as they left it in a right state, even though they sold it to me!
7) Fix some of the internal doors as they had either broken hinges or just wouldn't shut at all.
8) Fix the integrated fridge freezer, along with a new set of brackets as they had just removed them, drilled bigger holes so the original brackets didn't fit anymore (plus they didn't leave the originals anyway!)
9) Replace carpets / paint the house, as it hadn't been painted for about 10 years - although this is kinda standard 'move-in' stuff.
Plenty more, that I have forgotten in the stress of it all!
They were not council tenants or renting that property either, ridiculous really.
...But other than that, enjoy your new houses/flats
