I've been very reluctant to join in any of these chats in case I jinxed things, but we're looking to exchange any day now, and have today proposed a moving date of 13 September!
It's all gone remarkably smoothly - we were the first to view the house we're buying at the beginning of June, and put in an offer the next day. We hadn't got ours on the market, so marketed ours the following week, and got 2 over-asking offers within 2 days. Our buyers are cash buyers, don't need to sell their house to buy ours, and our sellers are going into rented until their next house is ready (refurb job), so a very easy chain.
I've found this section so helpful, and my heart has been in my mouth for so many of you, I wish you all good outcomes.
