I thought Bella was doing OK ... reality TV show, appeared at WM30 and I think she's been seen on Raw lately.
As I read it, Brooke has been off TV because she was pursuing her real estate license, not the other way around.
It varies from state to state, but I have a relative (my brother's ex-wife) who got her license and it's a process that requires a couple hundred hours of coursework AND working in a real estate office as an 'apprentice' for for like 2 years ... as well as a lot of tests you have to pass.
It's not the kind of thing you do to put food on your table when you're suddenly out of work, unless you've got a nice nest egg to spend while you go through the process. You don't make much money in the apprentice and classroom stage, and, as noted, that's a couple of years. Once you're through all that and you're a licensed agent, you can start making real money (if you're good at it, in the right place, if the market is favorable, etc.).
In both cases if that's what they're doing, they are planning and preparing for their futures outside of wrestling. If Tess was kicked to the curb and needed to pay rent and buy groceries, she would be working a 'regular' job rather than taking classes and working toward a license. It's not an immediate payoff.
