I can finally join one of these threads as a purchaser - yay! I remember a few PP from the countdown to 30 June thread.
Put my house with EXDP on in April, completed at the end of June, and moved in with family to accommodate buyers wanting to complete by the biggest saving stamp duty deadline.
Nothing was coming on the market for ages, now I've finally found a lovely house in one of my two preferred areas, and had an offer accepted £10k under asking (it was overpriced).
There are only 3 in the chain, me, my vendor, then theirs is a probate purchase...except it hasn't been granted yet, though I'm told it's due imminently 
A slight delay in timeframe suits me as having applied for a huge mortgage direct rather than through a broker, and the bank have said they need to see 3 months maintenance receipts, despite me being able to afford to pay the mortgage on my own. Their stress testing mechanism says my payments "could go up by 73% if interest rates rise". I'm not quite sure how that works out seeing as interest rates are at a historical low, but the computer says no. I actually only need to wait until the end of August for the final month's proof of maintenance receipts, but it's hugely annoying having to put my application down for the moment.
In the meantime my solicitor should be able to move forward with searches etc, as it'll at least show progression with something on this purchase.
