I did a quick search on whether home businesses count towards this lifetime want, and couldn’t find many answers. I found a pretty good discussion at http://forums.thesimsresource.com/archive/index.php/t-327985.html about making successful businesses, and they believe home businesses count. Has anyone confirmed this? My only top-level (level 10) business so far has been a home business, but it doesn’t belong to a Sim who has the “Own 5 top-level businesses” lifetime want. But his fiancee who lives with him does have that want. I’m pretty sure home businesses can’t be transfered or sold to other Sims. I will try moving the him out and moving back in, and see if the home business transfers to his fiancee.
