Entering real estate through house hacking duplex

[Tyron Betton]

I'm looking to get my foot in the door of real estate investing. My plan is to purchase a duplex or 2- family home with a FHA loan using 3.5% down and renting out one side and moving out after a year. After I move out i plan to purchase another duplex, using the BRRR method, live in the property for a year then move into a home of my own. From there I plan on financing fix and flip projects thru the BRRR method and using those profits to purchase single family homes and duplexes. I'd like ANY feedback from ANYONE who has taken this route, was using a lender a better option? Were you not approved for certain reasons? Some problems you might've faced with BRRRR method? ANY FEEDBACK is appreciated!
