For most people real answer is finding really good places that they can use some combination of their assets and borrowed money to invest.
However for you right now -- think Ramsey.
The key to financial independence is to live on less than you make and invest the rest wisely. You're just starting a career that should spin a comfortable living for a long while. Don't screw things up by taking your eye off that ball. There will be time to invest later. But spend the next few years getting ready to invest.
First get a good budget in place. Figure what you need to live on and invest the rest in a good mutual fund (after paying off debt, see next paragraph). Get good financial habits like tracking every dollar that comes through your fingers. Manage the dollars wisely and let the savings accumulate.
Next-- Pay off any debt you've accumulated in Gainesville, including student debt, credit cards, and any auto loans.
Make the beginning of your career a success. This will make a lot more important to your financial well being at age 40 than real estate investing.
After all of these are in place, then start looking at the real estate market. Maybe a home first, investments later. Or maybe skip to the investments if you wish. But for the first investment you should be debt free and have at least a 40% down payment in place. Even more would be better. You can borrow more for later investments, but learn the market with less risk than maximum borrowing.
You have a long working life in front of you. And you probably won't retire at 40, few do. But you can have a very good foundation in place to eventually get there. But now is about preparation and getting the foundation right, including paying off debt, getting good financial habits, and making yourself a really good engineer. The investments will happen in their time. Don't force them before that time.
