It’s better to be optimistic than to lose a buyer because you’re too slow. In a hot or rising market, even the best solicitors can take a couple of days to prepare your sales contracts. While the use of offer and acceptance documents is now almost ubiquitous, they are almost always (for good reason) not binding. A lot can happen in those 2-3 days while the contracts are being prepared, not the least of which is cold feet. As soon as you’re on the market, get your lawyer to prepare draft contracts so that they are ready and waiting to use.
