The right hand chimney is leaning outward isn’t it? And though it’s hard to see, the pink circles show that the gap with the neighbouring property is wider at the bottom than at the top (by about an inch).
I don’t want to waste £££ on a survey if there is obviously a structural problem, I’d rather save my pennies and walk away. On the other hand if there’s a possibility that it’s just a quirk in an older property, I would consider it worth spending on a survey to find out more.
What do you think?
