DH works in real estate. You will work all weekends. You will need to plan around certain "office" meetings, etc., weekly that you need to be part of. Generally, there are broker tours during the week you need to be part of. Overall, it seems to be about a 7 day/week job, where you are always "on call" for your clients. You can make good money, but you need to put alot into it to start (both effort and money). Also, there seem to be a lot of politics and clicks at certain offices that you need to figure out how to navigate. You're an independant contractor - so no guaranteed pay, no benefits, etc. Plus, if you go on vacation, you need to pay someone to cover your stuff, and possibly lose out on a lot of money if you miss something big that comes up while you're out.
DH did love the work overall, and it was a good fit for his personality. But then we had to move for my job, and he decided it just wasn't worth it to start all over in a new market. So, he will now embark on a 2 yr or so career as a stay at home dad once the new baby comes, and we'll see what's in store for him career wise down the road.
