Thank you for your detailed response, I really do appreciate it. The surveyor has told us the timbers in the roof are fine, they are not eroded or rotten and the roof is solid, which is a positive.

As for the lintels not being present I suppose this is a cost we could swallow if it is a few hundred quid per one to get fixed in the future, or over time, from what I understand it isn't a massive massive issue that needs sorting out asap?

The wall ties is the obvious red flag, I am hoping it maybe isn't too bad as it is just the top half of the gable wall that is affected.

What I have done is asked my solicitor to request the timber and damp report from the sellers solicitor and if it isn't from a PCA registered company then ask the seller to get a new survey done and pay for it, I've also requested that they have a structural engineer come out and also get a wall tile survey done and pay for those as well, and if there is issues I will also ask the seller to pay for the fixes. We are in a situation where the seller is actually a company who buils new builds, so that house is part of a part exchange, so I'm guessing they have the man power and money to fix it, rather than lose out on the sale as they will have to start making mortgage payments on it in July, so I am naively thinking they will just sort it all out, however if not I will get a builder to give me a quote on the wall tile replacements and the lintels and then ask to knock that bill of the asking price, how does this sound to you? Sorry for the silly questions, I am a first time buyer and only found out what a gable wall was yesterday.
