Having a pre-approval or at least an established relationship with a lender shows sellers that you're serious and can close quickly, which can make your offer more attractive.

I am currently seeking funding and establishing partnerships with agents who are knowledgeable in alternative financing and real estate investment strategies.

You shouldn't do the PMs job, you are paying them, but as the first time working together I would use it as an opportunity to learn and establish the relationship.

Please be gentle; I'm new at this and it's pretty complex :)Structure / Legal Details- we'd establish market value through a combination of comps from local real estate agent and an appraisal- attorney would establish all required "arms length" aspects including a mortgage at a minimum standard federal rate- LLC would pay us back based on a standard promissory note over 30 yrs Pros of selling to the LLC (I think)- A sale now would be the only time we'd be able to take advantage of the cap gains exclusion on this house bc we won't qualify for the "live there 3 of 5 years" rule due to the timing of our lease and our last time of residence. 

For 18 years, I thrived as a mortgage broker in Texas, helping countless families achieve their dream of homeownership.

None of the names listed above appear to be pivoting into the homeowner association space, yet here in the northeast USA it's still quite a fragmented industry outside of the major urban centers with established and deep-pocketed PM firms. 

It is well established that states are allowed to regulate licensure etc.

It's creating and following processes that has helped my business thrive.

Is this possible even without already having an established business? 

If you want a lender for a property on the island, they must have an established bricks and motor bank on the island.
