I don't understand how people's sims get rich so easily. I struggle 70% of the time to keep their household funds above a few thousand at a time. I build a lot, so my money mostly goes into upgrading the house. My sim is currently saving up to one day buy a retail lot, which would once again take a long time to gradually upgrade as my sim makes more.
You could try doing this. Building (or downloading from the gallery) retail lots, vet clinics, restaurants etc that your sim has to upkeep and upgrade. Become a property big boss. You can even franchise your restaurants and retail - create a whole line of your specialized products. Kick the Landgraabs to the curve. If you haven't already used Newcrest for other purposes, fill it up with your monopoly.
