Thought I'd update and tell you all how it turned out. I submitted 14 large masterpieces and 1 portrait and I got $455,000 *jaw drop*
455,000!!!!!!
What do I do with all that money? I only wanted a sports car! Maybe I should buy a big community lot like the swimming pool? Do you get revenue from it each week like you get when you buy the small business e.g the grocery store?
My single mum sim is doing pretty well for herself. She's an astronaut, paints, and owns all the small businesses outright. Her teenage daughter is well on the way to also becoming an astronaut. Do the business ownerships get passed down to the next generation when the one who bought it dies? If so, the younger sim will probably never have to work! She's mean spirited and likes to troll internet forums. Tsk. I don't approve and stop her doing it when I catch her.
Anyway, yes, thanks everyone for all the tips and help!
