Delaware Statutory Trusts are a vehicle for investors, while 1031 exchanges are more of a private toll road that helps navigate investors around the IRS (and DSTs are one possible vehicle that can access this private toll road).  

Any “license” needed to operate an LLC as an investment vehicle is going to be required by a local area - but offhand I don’t know of any.  

We will have a support vehicle, a mechanic, a medic and guides and I feel that's the stuff that is totally worth spending money on. 

Renovating this additional 900 SF unit would obviously massively increase the property value as well but what other creative ways could I utilize this space for cashflow besides renting it out as just vehicle storage?

Unfortunately, your W2 is a great vehicle for your investment properties, gonna need it to get the best loans.

It is just a payment vehicle.

All this is free to search.By using paid subscription services, almost all of your personal info is available: previous/current addresses, phone numbers, email addresses, voter registration, owned vehicles, neighbors and relatives and their contact info... the list goes on.You might consider getting your properties out of your own name to get the target off your back.  

Remove the virtual staging, get some drone shots as well probably cost an additional $300-400 so one could get an idea that it's a corner lot and it's spacious to entertain/park more vehicles.

@Ryan SingWhile an IRA may be used to invest in real estate in many ways, it is not designed to provide additional capital to your flipping business.As a tax-sheltered vehicle, all investments of the IRA must be conducted at arm's length and exclusively for the benefit of the IRA.  

You also need to understand how many units or vehicles you're allowed to place and what codes apply.RV pads might feel like a last resort, but if zoning supports it, that could be your quickest path to cash flow.
