Beginner mistakes and what steps to take to fix them

[Zack Whiting]

So I am new here and to real estate investing. I have made a few mistakes that I could use some help/ advice to solve. 

1.) I have two rentals that I currently rent to a friend and the other one to my brother. With no lease or anything legit in place. I have been treating the rentals as a hobby.

2.) I did not include vacancy, repairs, management, and other cost, When determining what I was going to rent them out for.

How would you guys go about fixing these problems?
