I’m curious as to what the best ways to gain credibility in the community as I am equipped with best practices of the business, but I am looking to gain credibility and a positive reputation in the community so that I can get past the hurdle of your first deal or two.

Again, this is no necessary for the loan but is a good practice to show to help with the keeping personal and business funds separate.Hope that makes sense. 

I am thinking about getting a Heloc on my single family house (also my primary residence), and use that line to invest since I used up practically all my savings to buy this house and my credit score has gone way down because of technically 3 mortgages under me now.

Brandon Turner has a few YouTube videos and webinars that will help you analyze a deal for practice. 

There are ZERO used homes for sale in Iowa that can be relocated to a new park so I kind of know what you're going through.
