As far as the monopoly, why don’t you just self manage?

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.

Quote from @Nick Am: Hi All, I have 2 multifamily rental units that I entirely self-manage.

You need sufficient NET (after all expenses) self-employment income from something like contract (1099) work, being a Realtor, wholesaling and so on.

I feel confident it is low risk and mitigated with the added deposit. 

If for some reason they can't get this sorted out by the next payment date, you should figure out how to physically escrow that payment somewhere...this at least protects your payment until you're confident who it is supposed to go to in the future. 

It's in great location that I'm confident will continue to appreciate.

This means taking days off of work to handle business, dealing with the subs and any deficiencies they may have, spending time dealing with the city, for both permits and inspections.Having GC doing everything won't entirely eliminate your time cost, but it can mitigate it to an extreme degree.My take is that if you are confident that you can be as fast as the GC in handling everything and there is no negative impact to your other business then by all means do it.

@Andrew Self I would like to think that my company is the best and offers the lowest rates and closing costs, but perhaps I am bias.

Wife and I are both self-employed so acquiring a traditional mortgage is challenging based on our "on paper" income.
