I just got this EP yesterday and I have more than one question.
I'm playing the FireFighter Career and Interior Design. That's a lot of work.

Cool Fire Truck!
But do my Sims have to have any special skills to become Self Employed if they switch jobs? At first I tried that but no options were on the phone for them to be Self Employed (The book or game said use the phone then go to City Hall).
The couple that is in the house that has a car out front on a platform...is there a way to have a yard sale in this EP? Or is the lot just pretend with the junk outside? Can I put a register on that lot?
I noticed I couldn't put the stacked tires in inventory nor the washer. I wanted to see if I could sell those at the consignment store.
In the Consignment Store, when I clicked on register to Browse, it just falls out of queue. Sim jump bug? or they can't really browse?
There are some of the Interior Design remodeling jobs I would rather not do, because I like the houses (building) just the way they are. Don't want to add an addition etc. Can I skip those or will my Sim still have to do those at some point or will they go away (map markers)?
