What do I do next to continue growing my portfolio quickly?

[Brandon Wallace]

I’m 23 years old, working a full time construction job. I just bought my first duplex and plan on using all my free time to rehab the property (mostly doing the work myself). Once finished l’ll have a tenant in the upper unit and I will be moving into the lower unit (currently living with my parents) what is my next step to getting more rentals quickly and adding more properties to my portfolio? Thank you
