So after posting the list of things the survey apparently found I wrote the thread...
Ok, the survey's in... advice pleaseand thanks to awl for calming down. I agreed that my buyers could get estimates on work that might need to be done but was really very worried that they were going to try and knock me down with insignificant problems, or make problems seem worse than they were.
Two very decent older proper builders turned up today and had a look around. They found
NO damp in the bay, the air vents were all fine, floors were all fine, drains showed no evidencfe of either blockage or collapsing. They confirmed the damp I knew about and a little bit in the lounge wher next door is slightly higher than I am. The damp is coming from their side and is no trouble to fix nor expensive. So basically they said to me that there was nothing I needed to worry about ..... YESSSSS !!!!!!
Ok thats really a double double WOOPPEEE as the house is as I knew it to be, however...
I know surveyors have to cover themselves saying likely problems in houses of this age... but why do they need to phrase things in such a way that they don't give the opinon that in this case this isn't a problem rather than drawing your attention to it and needs to be fixed right now !?!
For an update... spoke to my buyers just now (lovely to be able to do as I don't have an EA) and their buyers have their mortgage offer and I already knew they did... now I'm happy

Just still need to find me a place to rent for me and my animals
