Transitioning from house hacking a small multi-family

[Eric Sipe]

Hello,

First of all, I am new here; thank you all for being part of this community.

I have recently started my journey in real estate. I am committed to buying a small multifamily property (duplex or triplex) in/around St. Petersburg, Florida. I am going to house hack (live in one unit of the property while renting out the other one or two units).

My question is this: how do I transition from house hacking a duplex/triplex to having a real house of my own and also expanding my RE portfolio? I obviously want to have a house (but would be fine living in another small multi-family for a while) but also want to keep buying other rental properties. Is there a good way to achieve this? I have read multiple articles and watched many videos about house hacking, but none say what to do AFTER your house hack. 
Thank you,
Eric
