Hey Manuel there is a lot here and I am going to try and stay simple hopefully not too simple.
First, good job on ignoring the negative vibes out there. You will get tons of them and as long as you have a good plan and you stay on it you can achieve whatever you want. Everyone is told to goto school get good grades get a job, personally I'm not wired that way but everyone is different. A lot of people on this site are the same way and we have all seen tons of negativity.
The most important thing I can tell you right now is get educated. You say you want to learn rehabbing or landlording, I would pick something and stick to it. When you learn it and learn more about real estate then see what else may attract you. You want to keep your money safe so I probably wouldn't tell anyone you have it. If you have good credit maybe bring that to a deal.
The absolute most important thing you can do is find a mentor in the business, or many, who will allow you to learn. A good mentor may be able to use your credit, but most importantly you'll be able to learn about this business and not needing millions of your own money to be successful. The more people you surround yourself with that are knowledgable the more successful you will be in this business.
Everyone is different and everyone has gotten to where they are different ways so it's hard to start where someone else tells you because you will get a ton of answers. What just about every person on this site will tell you to do is get a mentor, or a few, and become educated. Keep reading and studying real estate for whichever path you choose and find people who are doing what you want to do successfully. When you do that you will start to figure out things to bring to the table and you will naturally start making money as long as you keep working hard.
Hope this helped!
