I don't mean to piss all over the guy who has worked in construction but their is no way of determining what needs to be spent on that property just from looking at images because a full survey would be necessary to identify structural issues, subsidence issues, potential damp and so on.
Current needs for reconstruction and renovatons are estimated to about 2
BTC : incl. Internal heating system, water reservouir, renovation of internal doors and floor, Bathroom with Toilet and Shower in each room.
The goal of new owner is to make from it a 4 room B&B.
Co-investors are still welcome.
