This include conventional, creative options like this 5% down option, DSCR, non-recourse, commercial, LOCs, HELOCs, installment loans, bridge loans, etc. 

This would be a non arms length prohibited transaction and would potentially result in the entire IRA being distributed is my understanding...the only way this could be possible is if the OP is or becomes retirement age in the next two years.

The landlord’s options include personal service, service by mail, and service by posting notice in a prominent place on the premises.

Include this in your sales pitch when reaching out.3) Offer STR services to build up cash and get your foot in the door...Cleaning, eyes on the property, landscaping, running to the store, small tasks such as a mail collection/trash day, offer a STR experience such as setting up for bachelor/bachelorette parties or grocery runs, etc...I think there's a missed opportunity with service based businesses and STRs. 

...after you take out the debt service, capex, and vacancy, what are you left with? 

One benefit of giving ample notices has been getting the notice reciprocated from a tenant of non-renewal of lease (90 days).

Find someone that will loan you the money or partner with you on it that is non traditional like an investor that buys directly at foreclosure auctions in the area. 

I recommend shopping around though, as you will find very different prices for those services.

I have a non-qualified use question that's very specific:We relocated our family to the Midwest and we rented out our primary residence in Orange County on Feb 1, 2021.

Might be other tools just saying I don;t know of other dtaa services that are better.
