You can ID using the 200% rule and I believe there is a third option. 

Overlays are the extra rules that banks put on top of Fannie/Freddie loans to limit their risk. 

Looking to use creative financing though because I'm not interested in dealing with the banks and their stringent rules.  

Unless I’m missing something, the numbers seem to support renting it, even though I could pocket $175k right now. https://www.allpropertymanagement.com/resources/rent-or-sell.htmlI’d be very grateful for any thoughts you have.

See if their total numbers are anywhere close to 50% rule. 

For example the part on capital gains starts out with "a) Special Rules When Gain From Sale Of Property Invested In Opportunity Zone Property."  

The liquidity requirement varies from lender to lender, but  the general rule is 10% to 20% of the loan amount.. so, If you’re wanting to borrow a million dollars, you have to have at least $100,000 after closing; $150,000 or $200,000 is even better. 

I don't have a 100% rule, but if there are multiple judgements for collections on there it's almost certainly going to be a no. 

But that needs to be the rule. 

If you insist, you will want to talk with the park owner before proceeding as they make the rules there and will have the power to approve or deny your prospective tenants.
