Well one thing that can make the timer bearable to some extent is if they implemented specific timeframes where the chances of plots opening can happen. Like 12-2p, 6-8p, 7a-10a. When they unlock within these timeframes would still be completely random but at least it minimizes the need to camp plots for long periods. Also to prevent people from trying to sell just before specific timeframe, make houses available in at least 2 timeframes later then the house demo. Say someone wants to try and sell their house just before the 6-8p timeframe, the house wouldn't become available during that timeframe, but one timeframe in the coming morning like 7-10a or noon-2p. I feel like it would be a possible, and manageble workaround.
