I would really prefer a section 8 tenant that is employed with little to no debt (that is in collections).

Sounds like you’ve already built a strong foundation in multifamily and have a unique edge with your commercial debt background.

I do not have a lot of cash flow in general, so I would be taking an interest free credit card to pay for the furniture and if I evened out for a year then started making profit that would be great.

Retention: Reward six months of on-time payments with a $10 card.

I have my credit cards under 10% always so there's that route as well to finance the emergency and use the funds for the next property. 

Use a clear budget, timeline, and exit plan to either sell on completion and pay both liens from closing, or refinance to permanent debt and then sell or hold.

@Ruth Schrader-Grace there are loans that will not hold your departing residence against your "debt to income" ratio. 

If long-term rental cash flow won’t cover that debt safely, consider a wholetail/novate to a retail buyer, or sell on terms as the bank (rent-to-own/owner finance) to capture higher price and avoid full gut costs.

If your return for investing in another property is greater than 8.5%, than it would be beneficial to invest rather than pay off the debt (would want a sufficient cushion above 8.5% to justify the added risk and work of investing in another property vs simply paying off debt). 

They do not have an automated way to capture credit card transactions.
