Hey @Omar Naguib ,
That's great about getting into mobile home investing. I'm on the mobile home and land side myself but started with just mobile homes. I have three pieces of advice for you:
1. Educate yourself as much as you can. BP is a great place to do that. Check out a bunch of the books on Amazon related to mobile home investing. John's MobileHomeInvesting.net and Rachel's AdventuresInMobileHomes.com are great resources as well.
2. Evaluate your financial condition. I'm not just talking about how much money you have in the bank but also what is your borrowing power. I know that you're young so your credit is new but work to build that score up. And if you can make a little money in college with some W-2 income, you might be able to borrow money on personal lines of credit at your bank to be able to help finance that first deal.
Also, check with any of your close relationships (friends and family) and see if they would be interested investing with you.
3. Get started as soon as you can. One of the biggest regrets from established real estate investors is that they didn't start investing sooner.
I started investing when I was 21 but wish I could have started even sooner.
