I need to decide which survey to have on a 1910 detached house. I've heard the Homebuyers reports often just give lots of advice for further specialist input, so i'm torn between getting a full structural survey or a valuation report followed up by paying for a few separate expert opinions (plumber, electrician, structural engineer). Are the homebuyers reports really that useless? Does a full structural survey include everything ( plumbing, electrics...)? Am I missing any necessary experts, maybe someone to do with damp/timber?
