Regarding security with buying the property, I can't say I'm too worried about that.

@Tosin Oluwatoye a good way to test out your location is to put the concrete pads down, add a 30/50 amp outlet and water line, and then rent out the pads to people who already own their own tiny houses.

You will receive the security deposit in Checking but then transfer it to Savings.Savings: Hold the deposit here so it's separate from operating funds.

Imagine closing on a vacation rental that can't secure a permit?

You are going to blow a lot of money for a false sense of security that a good insurance policy can protect you from and save you thousandsThe LLc is the most overused and money waster used on single family rentals.

Most S8 tenants have a history of bad decisions and from all that, many have only learned how to game the system.We embrace S8 applicants, but screen them just like any other applicant.Many have an entitlement mentality and try to leverage their S8 voucher and pretend to be helpless:1) A percentage won't apply because they expect a landlord to waive application fees for them.2) Many cry broke and expect a landlord NOT to charge them a security deposit.3) Many of those same S8 tenants trying to avoid paying a security deposit, won't make an effort to call the list of nonprofits we send them that will pay their security deposit if they apply.4) A lot of them try to avoid paying for utilities.

It could be helpful to have a real estate attorney look over these agreements for added security. 

Plenty other (smaller) outlets in Miami Dade.

Why don't the banks simply charge a higher interest rate to secure the business and cover themselves?

Most investors  who pursue alternative lenders aren't able secure bank financing because they  lack the creditworthiness, experience or the deal doesn't pencil.
