We had a vaguely similar experience earlier this year: after much, much searching (not much on the market in our price range around here) we offered on a house and our offer was accepted. When we had the valuation done, though, the surveyor said he couldn't value it until we'd had a structural survey done as there was cracking in the rear wall.
All hell broke loose; my thread is on here somewhere if you need some light reading
. Started off with the EA and vendor insisting a structural survey wasn't needed and that we needed to push ahead, took a few days for them to cotton on to the fact that we couldn't 'push ahead' as our lender wouldn't allow it. Then they started insisting we didn't need a structural survey on the whole house and so we should just get the cracks surveyed; they were absolutely correct but then why make a fuss about us not wanting to get the whole house surveyed when we hadn't even said we wanted to. It felt a bit as though they were saying 'whatever you do, don't look in the cupboard under the stairs' - you immediately want to to look there! We suspected they knew there were other problems and were worried we were going to find them with another survey. They also pushed hard for us to use their 'friendly' structural surveyor - um, thanks but if I am paying then I'll choose my own surveyor.
We decided to 'think about it' over a bank holiday weekend - the additional survey was going to cost several hundred pounds, and when i talked to the original surveyor he told me even if the structural survey came back clear, he wasn't convinced he could value it at what we'd offered. Meanwhile - despite us saying we would think it over - the EA continued to hound us, trying to basically bully us as though we were kids and didn't know what we were doing (we're mid 40's and have owned houses all over the planet ffs). We asked whether the vendor would consider helping with the cost of the surveys and were told a definite 'no'.
In the end we pulled out, partly because we couldn't be sure we weren't pouring hundreds of pounds more into a house that the lender wouldn't force us to pull out of anyway, but mostly because the EA and vendors were unreasonable. We knew - the EA told us - that if the survey said work needed doing, there was no way the vendor would negotiate on price. I think if they had said 'hey, we'll help with the cost of discovery', even, then we would likely have pushed ahead to at least see what the additional survey said.
I was gutted, but we kept looking and a couple of months later found a house that was better for us (and cheaper, too). We've exchanged and will be completing once the vendors' new home has been built. We couldn't be happier with our choice.
Meanwhile the first house is still on the market, still the same price....
It is hard, but as a pp has said you need to make a business decision here, not a heart decision. It sounds as though you already have made lots of decisions to 'let things go', to try and make this work, and this is just the final straw. Several people here told me that if the house I was considering wasn't my 'dream home' then i should walk away, and they were right. You don't need to compromise to this extent on your home unless you really want to - and you certainly need to follow your solicitor's advice (that's what you are paying them for!). If you're not 100% in love with the house then I would go very, very quiet and let things just ride for a few days. When you finally return all the EA's increasingly frantic calls and emails, explain your concerns and that you are giving serious thought to whether you wish to proceed. Their response will tell you whether you need to pull out or not!
Good luck
