What else can the EA say?
“Derelict husk for sale. Will need £200-300k spent on renovation. Similar houses in the area in a good state of repair go for about £50k above the asking price of this one, so whoever buys this is going to make a six-figure loss.
Obviously there’s no chain, as the place is uninhabitable, and it’s suitable for cash buyers only as it’s unmortgagable.
If you have £300k in your back pocket and no financial sense, come and view it. You could sink years of your life into this property, and you’ll still only end up with an entirely unremarkable two bedroom terraced house in Nantwich”.
