@Elizabeth D. - @Joe Villeneuve is laying out great perspective. I've done a few courses myself - all have been less than $2,000. One of the courses I got through, tried it, and didn't like it - but I still learned something from it!
Do you need to spend $25,000 for a course? I don't know - maybe, maybe not - likely not. I think it depends on what type of person you are. If you need someone to hold your hand and give you all the systems then you might. But, if you like to figure things out a bit and have a little guidance then a few of the lower cost courses may be for you.
Another thing - Are there some programs that are not what they are touted to be? Yes! But there are also some great programs out there that give awesome content and can really make a difference between you moving forward and not.
Maybe you go and work for someone who is crushing it doing what you want to do in real estate FOR FREE. This will allow you to gain knowledge that you can apply yourself on your own projects in the future.
