All those disadvantages might be true, but I see one giant advantage - that house should be CHEAP. If the location is great, the yard is great, schools are great, but the inside of the house is dodgy, then you have a unique opportunity to get everything done all at once, your way. New kitchen, new heating, new appliances, all done to your spec. We did this and lived in rented accommodation while it was being done. It's not as expensive as you think and the end result is a house that is made the exact way you want, without old lady wallpaper and a washing machine in the kitchen.
Disclaimer: Just a thought, don't trust me, do your own research. KfDancer and XKOD are both smarter than me.
Consider putting in a ridiculously low offer and seeing what happens. Maybe the seller just wants to get rid of it, nobody wants to buy because the estate agent is frightening everyone and Brexit, and you can get it with a big enough discount to do all the work.
Off topic, but the nicest house in our development was owned by a lady who passed away with no family. The house was sold by some crazy method for peanuts, literally about %60 of what it was worth. I have no idea how those people wrangled the deal, but they did. Bargains can happen.
