Would you buy this house - historic neighbour dispute

[newdaynewchapter]

Found a lovely property, large house, completely up together - made an offer and been accepted. In the buyers guide the sellers said that they had a neighbour dispute 10 years ago in 2016 when they objected to their neighbours retrospective planning application - the council made the neighbours slightly change the roofline on their outbuilding and the neighbours were livid and seemed unhinged (have seen their comments on the planning portal). The way the houses are set out they are not close together and the sellers have said they have enjoyed their home and have not had any issues with the neighbours since. Any thoughts?

None issue for me, its 10 years ago over a specific issue that has since been resolved and is nothing to do with you, so I can't see why you should have any issues.

Wouldn’t bother me.

For me this would depend on how close their house is and how unhinged the comments were.

I would go knock on the neighbour's door to say hello and introduce myself, and decide from there. I do that with every house I buy whether anything is mentioned in the TA6 or not.

Wouldn’t bother me on paper. I’d go an knock on the neighbour’s door to say hi though and just see what type of people they are.

This wouldn’t be an issue for me as long as there had been no further disputes. Neighbours are entitled to voice objections about planning applications and it is not unusual for the person wanting to redevelop/extend to be upset and voice comments if neighbours object to their plans. It’s how it’s dealt with afterwards that is the crucial factor.
Your seller has said that there haven’t been any issues since, so hopefully everyone has moved on in the last ten years.

If it was a boundary dispute, then I might have doubts. On a 10 y o planning application, it wouldn't bother me.

Sounds like the planning issue is laid to rest and shouldn't affect you.

Or is the question should you be concerned about living in close proximity to a volatile couple? That could happen anywhere, at least you are forewarned and there is some evidence that they have matured over the years.

Wouldn’t worry me.
i would just be polite and keep my distance.
I would also -before completion- do a few evening/nighttime drive-bys. Just to check,

Defending if you are planning to do any extensions etc. be prepared for them to object.

I wouldn't think this kind of dispute would need to even be declared, plans are submitted, people can object, that's not a dispute, its just the process.
