It's possible that it's different on console and motherlode also requires the cheat. On PC we don't have disabling trophies at all with cheats but for us the achievements are per save and basically useless. Maybe they made all free money cheat testing cheats on console.
Motherlode just adds money though, it doesn't give you any other signs that it worked. Since you say you were able to buy it now, do you have more money ?
I see.
Indeed, when I watch cheat-related videos on YouTube, even freerealestate and motherload start off by explaining that they're testing cheats on.
My money didn't increase and I was still at §20,000, but I was able to buy it as a vacant lot, so now I'm living in a huge piece of land with no roof lol
