Investing while having to co-sign with parents

[Reese Alley]

Hey guys, as you can probably see, I am new to the forums. However, I am not new to the idea of real estate and its vast potential. I am 17 with a small landscaping business doing about 7k a month in revenue and I can hold down about a 65 precent profit margin when I am not buying newer better equipment. Next year I will be doing 140k plus a year hopefully at the same margin. While this is enough to get into real estate I will still need to co sign with my parents because I do not have two year self employment history. Are there any rule of stipulations to doing this? I have plenty of mentors to help me and will be ready to go full throttle next summer with everything I have learned over the past few years on paper. Thoughts?
