I'm breaking out of my comfort zone here, and hoping to gather a little bit of advice before I finalize a deal on a 14 unit mobile home park.

Finesse the numbers/comforts and come up with a price for your trailer. 

I hope to be in a position to feel comfortable using some of my life insurance money into some form of a house hack in a year or 2, but the sooner the better.Basically, I have no stable income to buy a house and start investing how I want to.

Just step into a buyer's shoes.

I am more comfortable with credit unions and would prefer to stay with a credit union.

@Brenna CroweEveryone has their own opinion relative to the amount of risk they are comfortable with.

Sounds like you'd take a hit on lifestyle, but you could downgrade and survive comfortably.

Not only do they need to be excellent at what they do, but they need to communicate with you in the manner and at the frequency that is going to make you comfortable. 

Bottom line - sweet spot is in 4-5BR cabins for peak ROI, but all sizes will cash flow well, so it's okay to just go with what you're comfortable with, too.  

It is a seller’s market, so you are going to need either a pre-approval or proof of funds to even present an offer (even a lot of off market non MLS sellers will ask for that)2) determine what neighborhoods you are comfortable with.
