Dear Craftyone, glad you are feeling less stressed. Moving house is one of the HUGE stressors in our lives.
When I sold my flat, I was lucky enough to not have to buy at the same time - that would have trebled my stress, which was already high enough.
As others have said, it was only after my first buyer dropped out, and my solicitor went through the written questions again, plus different ones, did I realise that I didn’t have to know the answers to everything, and that I didn’t necessarily need to know where all the paperwork was.
Plus, we couldn’t find the FENSA paperwork for our new replacement windows, and as long as everything was at least one year old, my solicitor said you can get a VERY cheap one-off insurance policy to cover the glazing installation, etc.
And from my experience, sometimes buyers or sellers (or their families or neighbours!) can get very hung up on something that simply does not matter, like leaving carpet or not. Anyway, I sold eventually, and bought, and after a year or more, can look back on it all with a sense of relief and am very pleased I persevered with it all!
