Random hidden timer ok but don't make it to riddiculus amounts like up to 24 hours. Don't encourage people to sit in front of the game that long just to get a house.
Also as I mentioned. I can sit there for many hours just to see someone relocating. It's a very bad system.
With previous system, when people where flipping houses at least I was able to get one without spending hours, days and months trying to get a house. Now it's super hard and creates unhealthy competition between players.
