When to get out/ move on on a property?

[Quaid Cde Baca]

Hey all!

I'm now 1 1/2 years in on my first out of state rental property, a duplex, in Davenport, Iowa. It's in a rough part of town, ~C neighborhood, with a nice & reliable section-8 tenant family, with the other unit recently vacant via an eviction–costing a few thousands in turn over repairs. The property cashflows nicely, and has grown some equity. I want to build a long term rental MFR portfolio–not necessarily in Davenport.

Based on this info, my goals, me being new to this, and the numbers here on my deal:     https://dealcheck.io/s/-MmV1dHjb59npcOnRFJV     what would some of you do? Keep as a long-term rental, or 1031 into a nicer market?
