Ideally completing light renovations like this shouldn't take long and you should  have a low holding cost on the hard money loan (if you used debt) and make a higher profit on the sale or have more flexibility on the payoff when you refinance  Plan on long-term and hold.

AAA is there debt on the existing property?

I think paying off a loan with a high interest rate debt and adding to the principal is one way to stay liquid within the property. 

This is standard business practice - just look up how many settlements the SEC makes annually where companies pay millions in penalties WITHOUT ADMITTING to any wrong doing.- Cash-for-Keys is another example of this!

I have an experienced opinion on the matter, but am seeking outside perception and strategies, if any.Additionally, what are the implications of the NAR Settlement regarding this strategy if any?

Most investor utilize short term hard money debt to scale their flipping operations where the lender will fund 80+% of the purchase price and the rehab budget which can allow investors to work on multiple projects at once.

I would use money from a HELOC that I have open to fund the down payment, but as @Scott Trench stated recently on the podcast, that is a short term solution, and I don't want to hold that $48k debt for more than a few months. 

If you use debt to buy the real estate the IRA will incur UBIT so educate yourself on that. 

So I did that and my property revenue cannot service the debt but using my strategy I'm cash flowing $1100/month after PITI on a new construction home under warranty. 

When an IRA borrows funds it can lead to a tax called UDFI (Unrelated Debt Financed Income Tax).
