Why would anyone put in an early offer? Because if you’re a prospective purchaser and have your ducks sorted in a row, you can bring the whole thing forward to your advantage before the others are sorted.
True, but if others are really interested, they will quickly also get things sorted as well, if they have registered an interest. 2-3 days is probably enough time, especially as agents these days insist on sellers getting building reports done by the vendor. The main advantage as a buyer to do it IMO, is to do it when it initially hits the market, to reduce the number of people that see it advertised, and thus reduce the number of people who may bid on it so it reduces the competition of buyers. But I doubt that many sellers would agree to do that, unless they are already 100% happy with the price that is being offered.
