I believe it takes a really shitty person with no integrity to sell something on, knowing there are issues, without highligting them.
Whereas I know it is. But that still doesn't mean a seller legally has to.
We had the mains water tap turned down to regulate the water pressure and a bloody noisy pump for the shower. On removing the pump, replacing the boiler the water tap was turned on properly and we found that there was a leak under the floor in the kitchen. A fully tiled, expensive Welsh slate, flooring.
The obligatory house insurance included a gas and water service contract and they very carefully dug up two tiles, found and fixed the leak and then replaced the tiles nigh on invisibly. Too about 4 hours - free because of the insurance we took out.
And the conservatory roof panels were on upside down and so drew water in instead of repelling it - took about 5 hours , DH did it himself
Let me see, oh yes! Fuses were all overamped. We have a freind who fixed that. But it could have been disastrous.
All water pipes were overcrimped and leaked just a little bit, but were all one 'judder' away from catastrophe
Lots of additional electric cables. Cable lengths joined by switches - cos the last owner was an oak joinery specialist and hadn't a clue. Took DH hours to remedy that one too.
And his doors? Dear god. They look beautiful but he put the hinges on the fucking ledges not on the flat of the door. So they all slowly bend and drop and catch on the floor - have to be tightened every couple of months. We have a choice. Live with it or ruin the doors!
And much much more including, as we found out a few months ago, a burned out chimney beam that he just plastered over. It's a listed house, will cost tens of thousands and many, many months to put right!
But that doesn't mean I think that he did anything wrong - well, he did with the chimney but we can't prove it was him. He was just a fucking Bodger!
