20 year old starting out in Real Estate investing NEED advice

[Drake Bigley]

Hello guys I'm 20 years old and want to build up wealth investing in real estate. From what I've read about the process it really intrigues me. I currently have $300 dollars in savings but with my new job I'll be putting about $800 a month in savings. I plan to start school next semester in August, and in March I will be going on a three month mission trip. So I have some pretty big things coming up in my life. But this doesn't effect my drive to want to start my investing career now. I'm a very drivin, and business savvy individual and beyond my years in knowledge about finances and investing. So here are my questions.

How much money do I need to start an investment? And with the mission trip and school coming up would it be smart to start now? Or should I practice patience?

Also how will I know I'm ready and knowledgeable enough to make my first deal?

Lastly how do you find the estate you want to invest in?

Any wisdom from an experienced investor would be greatly appreciated
