These are self managed through my small STR management company.

They tend to stay to themselves, not a lot of company or complaints. 

My main focus on Florida stems from an established working relationship with a property management company there.

Quote from @Rodney Davis: Has anyone done a deal with this company, Strategic Investments Partners? 

These companies are fly by night hence why they don't buy their own properties...

Or using a company ?

You could even consider investing in a Real Estate Investment Trust (REIT), which is a company that owns income-generating properties and distributes part of its profits to shareholders.

Applicant credit scores should be treated with a high level of care and should not be handed out when they aren't assured that you are locking them up and taking due care with private and sensitive data.So, many places, including the screening company we used for years before moving to a PM, provide a suitability score rather than the actual credit score. 

I have spoken to both a mortgage banker and a modular cabin company and explained our situation.

You'll want a title company/closing attorney who understands how to do this correctly.
