Not sure what advice your after but if you employ the services of a surveyor they can tell you if you need a rewire, new heating/plumbing etc etc. I'm in the process of buying a similar property condition wise, I've set aside £100k refurbishment budget. Getting proper tradesman in soon adds up. (Mine is a 5 bed and I'm putting a new roof on and working my way down to include new electrics, heating/plumbing, bathrooms, kitchen, windows/doors, plastering, decorating, flooring etc). If you have no prior experience be warned it can be pretty daunting and stressful. If you want an easy life, try and buy a property which has already been updated/modernised.
