Lovely position but it looks like a money pit.
It looks like it probably needs rewiring, replumbing, new bathrooms, new kitchen
Also reckon everything will cost at least triple because it’s listed. Plus the permissions etc. There’ll be extra external maintenance due to salt etc.
Buildings and contents insurance will probably be huge as well.
Looks like stacked corridors to me on the floorplan too. Not family friendly.
Then there’ll be the crowds practically sat in your garden on nice days.
If i was going beachfront I’d get something a little less high maintenance away from the main crowds.
