Our house was ridiculously cheap for our overpriced area - at least £100k cheaper than others of same size and location. The reasons? Dirty, front garden fence kicked down, cluttered, period features ripped out. And the decor! Living room and all through the hallways: dark fluorescent orange, a colour I have never seen on any commercial paint chart. Kitchen: yellow (including ceiling) with scarlet woodwork. Bedrooms: purple. Lots and lots of orange pine.
But it only took a couple of thousand pounds to put that lot right. I'm so grateful most people struggle to 'see' a house beyond the immediate decor.
