It's not always a blind auction or closing date in Scotland but is quite frequent for popular properties, you want to avoid these if your a buyer as it'll cost you more.
We had solicitors/estate agents use us in quite a manipulative way. We were moving to the north of Scotland and saw a house we liked but when I called it was sold subject to contract, no viewings possible but they took my details. A month or so later they got back in contact to say the purchaser was dragging their feet and the sellers were considering putting it back on the market, would I like to view it. So I got the other half and our boy on a flight up, booked hotel, viewed the property, liked it put in an offer and got our hopes up etc. However all the estate agent was doing was using us as a pawn to push the original buyers in to action which worked as we didn't get the house. The solicitors/EAs had no thoughts or concerns to what their actions had cost us or even the original buyers who could have been pushed to the wayside.
