I bought my current place a year and a half ago - it was the fourth one I'd had an offer in on and the previous three had major structural issues (turns out 100+ year old houses built on same are a nightmare), at least two had subsidence. I have friends and family in the building trade and they reckon they'd be wary - houses like a that reach a point where, to continue for another century, they either need to get snapped up by a builder who can get the work done and flip it or someone highly motivated who can take on a project like this.

Your mileage might differ but I'd just spent 6 months and 50 grand putting the previous house on a raft of concrete that would outlast the next I've Age which was then used as a stick to beat us down on the price. So I was not in the right frame of mind to undertake another building project. And that's what you should ask yourself - are you the kind of person that thrives on camping in their new house for months getting work done (and getting builders is trickier after the pandemic and more expensive)? What's your budget like because this is the stuff the survey found but tearing into the place could reveal more? It has clearly not been well-maintained for a long time and there's likely to be all sorts of other issues.

What level of survey did you have done? Have you had a structural engineer look it over?

I certainly feel like if they’re not prepared to negotiate re repairs then I have to walk away as I could buy a well-maintained property round here for the total cost of around £100k!

You're clearly up north! If they aren't prepared to negotiate then everyone should walk, if they weren't prepared to come down closer to £50-60k then I'd definitely consider walking, as the modest savings don't outweigh the stress. To be honest, if it were me, I'd be long gone already. Just reading this is giving me flashbacks.
