If you have the means to cover debt, you can avoid the accounts being liquidated.   

Often, I am not able to keep all of my ira funds invested in active loans so I would like to be able to keep the money that is not invested in loans in a liquid "money market" type of fund on a temporary basis.

This means the rental rates are average nothing to write home about, but the increase you'll get in appreciation is amazing, but not liquid until you sell. 

You will need 6 months worth of the payment (including taxes, insurance, HOA) in liquid assets to show an underwriter.Now with doing a rental agreement, do I need to have tenants living in the home first or new prospects lined up before the underwriting? 

Seeing as you mentioned you have very little liquidity in after-tax and savings accounts, I'd likely recommend focusing on building up a buffer of accessible and liquid dollars in an after-tax brokerage account prior to maxing out a Mega Backdoor Roth.

Our short-term residential investment property loans are typically 60-80% LTV and all are personally guaranteed by the borrower(s) -- we pull credit, background and PFS on each guarantor, verify experience, verify liquidity, underwrite the property, neighborhood and zip code.

Quote from @Lambros Politis: I'm looking to liquidate my modest real estate portfolio in the PNW via a 1031 exchange and move into a high-yield tertiary market.

More than four dozen investors pitched in, including some of the largest financial institutions and liquidity providers in the world, as well as prominent business leaders.

Their role is crucial in maintaining liquidity in the housing market, ensuring banks have enough capital to keep lending to homebuyers and investors.

Either that, or 0% credit cards combined with the personal loan if you feel that you can liquidate the property before the credit card intro periods expire.
