Having moved into a 1970s house with it's fair share of 'hidden' issues I think with houses like this you really have to go round with a fine tooth comb yourself, and then pay your money and take your choice.
If you go into it knowing that it might cost you a bit, but if you love the house and location, and the price is good considering you might have to spend a bit to get it to your standard (thinking about ceiling price for the road if you are thinking of selling it on a some point), then it can be a really good opportunity.
It does look fairly well up and together. Most things look serviceable in the short term at least. You can do decorating and changing bathrooms and kitchens at any point, it's structural issues and possible leaks and damp and things that I would be most concerned about at this point.
If you plan for a full renovation then you won't be shocked if you find something lurking that has been hidden by carpet/cladding/wallpaper etc. A local builder or renovation firm may be able to have a look around with you and let you know a guide figure for the works.
It looks liveable for now though, I certainly wouldn't be put off by it's current state. It looks like someone has looked after it.
I don't think sockets in skirting boards are within building regs now, so if you do get someone in to check the electrics that will probably be pointed out to you anyway.
