I'm a 16yo trying to learn wholesaling to start when I'm 18

[Armani Pimentel]

So I've been getting into real estate and found out about wholesaling and I'm 16, I've been studying and taking notes about the fundamentals and basics of wholesaling, I've decided to start saving up till I'm 18 for when I start wholesaling to be prepared. I've wanted to know some tips you guys have on wholesaling and starting young and what I should know before I start.

Important question: How can I calculate or give an educated guess on a property's repair cost on zillow
