Hi,
Just wondering who carried out the survey? What it something you asked to get done (to satisfy the bank) or something the vendor had done?
Ideally an engineers report will highlight any issues with the property before you agree to purchasing this. So not too sure what level of detail your survey is going into. If it's your engineer who did the survey, then I would recommend meeting with him/her & going into detail on this, asking for their professional opinion, etc...
It's a tough call to make, a big leap of faith, especially as the purchase price can be so much. Again, depending on the age of the property, it will give you an indication on the electrics / pipe work / heating system etc.
From my understanding, any structural issues (subsidence / water flooding) must be told to any prospective buyers upfront.
Engineers report is key to making this decision to buy or not & as they don't come cheap, make sure you get their time & go through in detail each of your concerns / questions.
