You have two unrelated questions here.Question 1My impressions of your LLC setup is that having the ownership change over time is too complex with the potential for misunderstanding. 

There was no "assign to property" option and basically I had to re-add their profiles to assign them to a property, which was clunky.

I like the idea of trailer parks and the target IRR is impressive, but ODC will have to absolutely crush it to justify the 70/30 and 50/50.

I recommend using a lender that non-reporting to personal credit and can close under the LLC to keep your DTI lower and overall your personal liability profile more bankable.

We also have a weekly newsletter for STRs here called BiggerStays that you can sign up for free in your profile settings! 

We're seeing up to 20% conversion to appointment on Facebook leads for example in 24 hrs.It's not perfect, but its pretty impressive so far.

I've got a great resource you can download with the lists (check my profile) on where to market your MTR. 

Congrats on owning a duplex at 20—that’s very impressive!

Maybe tell them you have done 800 deals and made 10 million, see if they are impressed and say you're qualified!
