can a survey be arranged and will it scare the seller off?!
Hold your horses there fella, nothing and i mean NOTHING is going scare the seller off so get that one out of your head for starters.
If you dont know much about basic building structures and such i would strongly suggest an independent builder, tell him what you want before hand and take it from there. To be honest you really need to know what to be looking for yourself, plumbing infrastructure, electrical wiring, state of the exterior and roof etc.. If its any consolation even the most complex housing renovations seem to be fairly easily solved by the average village guy.
