Can I ask what I hope isn't a daft question. When you get the survey done on the propety you've offered on, and the survey recommends to get other trades people in for further opinion- eg gas engineer for old boiler, damp specialists etc. And then you get all the extra info and quotes for work. I just assumed that most people would then renegotiate their offer - so say the property needs rewiring, which wasn't obvious when you originally offered, you revise your offer to be 10 grand less in line with the quote for that work? Or is this considered sneaky and like you're suddenly lowering your offer just before exchange? Even if there are valid reasons. I'm losing my way a bit here with this horrific house buying process!!
