The "good problem" of not knowing what to do with portfolio equity

[Micah Cook]

Hello BP!

I've been trying to strategize and plan ahead regarding my investments and managing my portfolio. I'm 26, but I want to be sure I'm on the right track. I've got about 250k of equity spread across 5 SFHs that I've acquired in the last year. I feel that I know the local residential market well and have a good grasp on purchasing solid SFHs. 

I know it doesn't hurt to continue to purchase solid homes at below market value in good neighborhoods but, I'm thinking about strategies to scale in a more efficient way. It seems the return is great on SFHs but inefficient in terms of scaling

I don't envision myself one day owning hundreds of SFH but I'm interested to hear what you'd do in this situation:

Continue to purchase good SFHs and hold?

OR "trade up" and get into larger investments to scale faster and more efficiently? 

Thanks!
