Which property should be my 2nd purchase?

[Robert Kohnfelder]

New here. Lots of helpful topics discussed, so I'm hoping to get a few opinions on my situation.

About 10 months ago I purchased a duplex in Pittsburgh, which I currently live in half, and rent out the other unit. Great stuff so far -- no regrets. Grew up here and love the area as a whole. However, I'm wondering what my next step/purchase should be...

Would it be smarter to find a single family home (my next move will be into a home, not another owner-occupied) and rent my current duplex out, and then buy more investments down the road? Or would it be better to save up enough to get another 100% investment property and find my SFH down the road? Is there a more common route to go here? I'm fine where I'm living now, so I'm not in a rush to move, but I don't want to sit around and miss out on a property (multi OR SFH) this summer if I'm financially ready.

Looking for opinions on what order would be the smartest.
