We moved last year into our 'forever house'. The previous owner walked out leaving everything. He took the sheets from the bed, (but left the bed), there were still towels on the towel rail, and all the pots, pans, (I gained five frying pans), knives, forks, crockery quite a lot of furniture etc. He emigrated.
The week after we moved the aga ceased working, I shrugged and organised for it to be serviced. The boilerman took one look and said, "It's obsolete, we can't get the parts, and even if we could it's been tiled in." He opened the boiler door, "It's been mended with mastic and cement. Oh and the oil valve has been taken out, so if there's a fire (which given the state of the 'repair' was not totally unlikely) all the oil in the tank would pump straight in." A mere £5000 later we had a new boiler and a space in the kitchen where the aga had been. Luckily there was a hob we could use.
He had also rejigged the plumbing in the attic, without any sort of fixings, so the pipes came apart. and the heavens descended.. Oh and he installed an instant electric water system, with no valve, so if it overheated it would effectively be a bomb. Sorting that lot out cost about £2500.
The latest is that I fell through the floor of the kitchen. He had replaced some ceramic tiles with cement without putting any membrane down, so the moisture from the cement rotted the floorboards. The whole lot was covered with very thick, good quality vinyl, so it was masked. We have to remove all the kitchen units to replace the floor, and as they are fairly old we'll have to have a whole new kitchen.
We still love the house, but finances mean we're unable to do nearly as much as we planned.
