But it's still...whole life insurance.

Quote from @Meliisa Lee: I recommend splitting the properties or selling them off and splitting the proceeds.

Nate @Nate Marroquin   You can use the income from your tax returns on the current rental adding back your paper loss (depreciation) and add back the mortgage interest, property taxes, home owners insurance deductions on your tax returns. 

I hope management works, but taxes are flying, insurance is flying, and I just wonder if I made a mistake with this property. anyway, sorry for the rant...

An agent should be able to send you a estimated proceeds sheet. 

Selling the property within your Solo 401(k) and returning the proceeds to the account simplifies compliance and ensures tax-deferred growth (or tax-free in a Roth Solo 401(k.)).

I think your biggest issue with any "work-arounds" is going to be your legal liability and holding the proper insurance in case something goes wrong, which I'm going to assume you'd need to be properly licensed in order to be properly covered by insurance.

The loan is listed on the HUD and they provide lender's title insurance.   

Plus with no state income tax, cheap insurance, and very low property taxes, I’m probably starting $20k ahead of most people, and that’s a tax free $20k.).
