So went to view today. There is leaking through the roof but only through the dormer roof at the back from what I could see where the felt is right off,which is now tarpaulined over badly. It has done some damage inside to the floor and celing upstairs in one room and hallway. From sleuthing it appears the house hasnt been lived in since Dec 2020 so surprised its not worse than it is. I think its well worth a punt at auction. Inside its mainly decorative issues, some repointing on one wall, checking out the retro fit insulation, which it definitely has and new kitchen/bathroom. Thanks for all the pointers. Certainly helped with the viewing today.
