Hi Amber
My wife and I are in the final stages of wrapping up our online real estate license classes at 24by7onlineschool.com which is another alternative to an online course. The classes themselves have been good and the format of the online class works well for teaching you the information in a way that helps you retain it. If this is your only option since you are overseas I say go for it and don't hesitate. Keep in mind that it does take some discipline to do this online, at home, with all of you other responsibilities vying for you attention. It also takes a long time. When my wife and I set out we committed to doing 1-2 classes a night and then spent some time doing other real estate investing research. This approach turned out to really drag out the classes. We've had to drop all other investment(research, reading, etc) and turn up the intensity to get the courses complete by the expiration date. At this point, we have a babysitter come over on Saturdays to watch the kids so that we can have an extra 3 hours to knock out 3 or 4 of the courses each weekend along with the hour or two each night that we are already spending.
Because we are already local, if I had it to do over again I would have gone to a 4-5 day class, not because I think I'd learn more, but simply to get it done and be able to move on to the next stage of our plan.
Bottom line, if you go the online route commit to it and plan to spend at least two hours or more every day on the courses. For the most part, the material is not hard it just takes a lot of time. Good luck and don't wait. Make the decision and move forward. The sooner you start the sooner you'll finish and have th hurdle out of your way.
