This arrangement was not disclosed to any new owners, and was not mentioned during the first meeting of the HOA that included new members. 

Generally speaking, you can typically get a higher price point with some type of seller arranged financing and sub2 is no different although this transaction would be much cleaner if you simply found a cash buyer, especially since it is a wholesale deal with what appears to be a lot of moving parts here.

o Should i ask about or ensure any specific details/arrangements with the lender?

Again, start with the end in mind, put yourself in the shoes of your ideal guest (even if it’s not what you’ll get to start), and base your bed choices off what arrangement suits them best (and your physical space allows).

Sounds like a good arrangement ...but you will be sorry big time !

Seriously, what type of arrangement is most common for owners distributions?

He may be able to negotiate some sort of arrangement with them. 

Prior to this ratified arrangement, roughly around 11/1/2018, I was contracted to purchase the above mentioned asset solely, without the “partnership” of Sean Richway.

Problem is they charge a fee if they arrange a successful loan, though in my case, it was waived. 

I’m considering a seller financing arrangement.
