Kimberly, I think you are going in all the right directions! It is absolutely awesome that you are interested in majoring in business and real estate! It's going to take you far, and you are going to be wealthy at a young age! I think it's also great that you are interested in building design, interior design, and landscaping. That will be very helpful if you are going to be building homes, flipping homes, and purchasing buy-and-hold rentals. You can also have a side gig in designing and landscaping for other people!
Many people start out in wholesaling, especially if they don't have much money to start with. Videos about wholesaling teach you how to evaluate deals that flippers and investors would be interested in buying. Which ones would be good wholesale deals for them, and which ones would be good deals for real estate agents? Wholesaling also gets you out right away talking to sellers and investors. Then after you make some money at that, you can graduate into investing, doing flips, buy-and-hold rentals, and more.
I found a great course online to study for my real estate license for $371, which is accredited in my state (www.trainagents.com). Real estate courses teach you all about real estate law, contract law, and financing deals, which I think is important to know. If you run across a deal that would NOT be good for wholesaling, you could list the home as their real estate agent.
Bigger Pockets has so many interview videos with successful wholesalers, and here are some of my favorite YouTube channels to watch: Max Maxwell, Kris Krohn, Phil Pustejovski, Clever Investor, Wholesaling, Inc., and real estate attorney William Bronchick.
Best of everything to you Kimberly!
