We haven't even managed to buy the plot yet, it's a complicated situation of an executor's sale and now the person who inherited has also died. The law of shitty averages surely says that because the first bit is taking for ever and is horribly complicated it means that everything else will run smoothly? (I know that this is not the case, but agree with me and I'll be happy until the next thing goes wrong.)
I'm also quite worried about planning permission, and we will need to sell the house that we are currently living in part way through the build. If we can't sell this house then the build will stall as we won't have enough money. The house next door to us went up for sale last year and they had very little interest and ended up taking it off the market without selling. We will be stuffed if that happens to us.
