I speak for myself and about 20 of my other friends who have mansions now, when I say that it takes a lot of patience and time. I had the Gil for my first mansion just before 4.1 (Oct 2017) and although I didn't log on fast enough to find a mansion, after 5 months of persistence and hunting, I got a large mansion finally. After the auto demo came back on, I see about one mansion a month spawn for purchase. Just don't stop . Check every single top of the hour that you are on game. Just two night ago at 8pm CST, a lav beds mansiok auto demolished and my friend got it.
