Being approved for a loan

[Keaton Walkowiak]

Hi! I am a 17 year old named Keaton and I have been learning about the real estate world for almost a year now, and I am nearing the stages of buying my first multifamily home. I am looking to buy a rental once I am 18.

 I have been asking around from bankers, agents, to my parents about how to get approved for a loan assuming I wait till I am 18 to buy. I have understood that I need a good credit score, and 2 years of w-2 paychecks to prove I'm making income. I do not have a credit card yet and I am looking for answers to a few questions... 

As a 17 year old am I able to start building credit? If so, how?

I have been told that I can have my name put on my parents card as an authorized user and then that would start building me credit, is this true? 

Any insight is appreciated immensely!

Thank you for your time,
