Are you responsible enough to make careful and conscious spending decisions and take good care of your possessions, or do you just impulsively buy them, trash them, and then go out and buy more once they get worn out and you get tired of them and want for something new?

Secluded, small, steep slope (most likely unbuildable land) & environmental liability. 

Bet on the appreciation you should generate and be conscious that your monthly HOA is likely to go up next year, so budget for that.

I asked if there are other fees, and was told all lenders have fees in addition to the origination fee, to cover lender costs for all credit reports, third party reports (i.e. appraisal, environmental study, property inspection report, zoning etc.), legal and processing fees (including travel costs). 

I’d take a conscious tenant who wants a decent place to stay at 50-70% of Airbnb rates all day every day.

You need to do environmental studies, and stay away from parks that have their own sewage treatment plants or septic systems.I was interested in investing in parks as a diversification from multi family.

But as right now, I can't move just yet, which is why I want to be conscious about the area to invest and hope for *some* cashflow

Engineering and environmental impact study's and reports.
