As far as self managing, it’s fairly easy.

Bizarre.My wife and I also have a self-directed 401(k) plan, @Tina Artigliere and @Alicia Prokos.

i think, in their defense, if you find BP as a new investor, sometimes you start at the beginning - the earlier podcasts, the webinars where Brandon looks at a random duplex on Zillow and it "cash flows" $250 per unit every time. 

One thing to be aware of is the FHA multifamily self-sufficiency calculation which determines if a property can generate enough rental income to cover its mortgage payments.

Going DIY and self-managing this type of asset from another state may not be an easy task for such a building and neighborhood, it needs more attention (and probably capital).Try an unconventional approach.

Avoiding accessive PM fees (personally I recommend most people self-manage)These will eat away at your ROI.

It’s worth considering self managing as a STR for depreciation benefits if the demand is there 

You might check with your Self-Directed IRA Trust Company/Custodian, they might have a brokerage connection capability where you can setup a brokerage account tied to your IRA, then you can with that brokerage to invest in various public market investments, in some cases stocks, mutual funds, ETF's, treasuries, and CD's.

If you own real estate in a self-directed qualified account, the 1031 exchange is unnecessary.

Of course my nosey self had to go look up your rental property.
