Ahh I feel everyone's pain here. The house before our current one had basically everything wrong with it, as soon as you start poking it all fell apart.
First it was the boiler, packed in in November (a week of cold showers in winter 😭😭), previous owner didn't service it once in 14 years 🥴
So that got replaced... But a few months later the pressure kept dropping. Can't be the boiler again, it's brand new!! NOPE it was several minute leaks in the entire heating system because whoever put it in originally used the wrong kind of pipes that can't be laid under the floorboards. So they were slowly disintegrating. Right so floorboards up through the house to replace the pipes. This was a slow process too because the plumber had to try to find where the leak was (haha idiot us thinking it would only be in one location) so he was having to check room by room.
As this was being investigated... Turns out the floorboards under the bath were rotted. Because the leaks were small, slow and steady. Used this as an excuse to redo whole bathroom. Which was a project on the back burner anyway that just got prioritised (goodbye rest of savings). This did also reveal an external wall in the bathroom that was getting drenched every time it rained and it was perpetually damp and caused the plaster to crumble.
If we thought everything was fine now, we'd have been suckers.
One day the FRIDGE kept tripping the electrics. Got an electrician round who said half the sockets were on a second circuit that was a bodge job and unearthed 😭😭😭 everything that had been plugged into this shitty circuit got replugged in elsewhere via several extension leads because we didn't have enough to do a full rewire at the time.
THEN we got an infestation of big fat flies with no idea of the source. Looked in every single cupboard and behind every single piece of furniture that could possibly have rotted food hidden. We were baffled because there was no smell. It was a dead rat in the sewage system at the entrance to our wastewater 🤢
And thus began the rat hell... That became a hideous cycle because every pest control we tried insisted on chucking down poison... So they were dying under our floorboards where we couldn't remove their stupid little corpses... Which brought more flies...........
There was also an infestation of little flies at one point that we never found the root of, but after months of putting up the sticky yellow pads they eventually disappeared. Tried everything from flushing out drains to treating every single houseplant to sealing every loose food item to no avail.
Somehow managed to stay in that house for 8 years... Have never been so happy to get shot of a place.
