Personally my realtor is always on the lookout for great deals for me.

So instead of driving around you can use pin to find the property and the person.  

So what I'm saying is just loading up your Gatling gun with money and spraying it at the problem may have little effect if the committee is hard-nosed to you personally, alcohol establishments, or just everything in general.

You could look at charging interest plus getting a percentage of the profits, which boosts your potential earnings.

Take advantage of it and have your maintenance person or property manager go and check things out at your property. 

I’m not really a “people person.”A PM can definitely pay for themselves just in higher rents, late fees, collection of damages beyond security deposits, and reduced vacancy.

Have you seen it in person?

Right now you're earning 5.14% interest on your money, and you pay income taxes on every bit of that $1800 per year.Meanwhile, I won't even consider a rental property unless it pays me at least 10% cash-on-cash return and a minimum of $250+ in monthly cash flow.

As you are using OPM and as long as the CAP rate is higher than the interest rate earned, it is a no brainer.

One way you could leverage a Solo 401k is by taking a personal loan from it.
