What do you do with your Simoleons?

I don’t like my sims to have too much money because I like them to have challenges.

But one of them keeps setting fire to their home lot with a magic spell and insurance grants them 500,000 simoleons in fire damage. Even though only a small patch of ground was singed <_<
Thus my sim family kept on racking up the moolah. So now they’re millionaires from insurance fraud :D

I just pretty much spend their nefariously earned money on renovating their house since it’s a huge mansion. Lol
