And boom you buy a lot for the price of a single lot and with some simple forms to the city you get to re establish the old lots..

My understanding is that O.J. used asset protection trusts established in Nevada with spendthrift clauses to protect his assets from creditors...   

I get CC offers on LLCs I establish within months of launching them.

Additionally:Is there a specific state where it makes more sense to establish the holding company (now that anonymity in states like WY or DE isn’t the focus)?

It's not a get rich quick scheme, it's a lot of active work and I would have 5 yrs in my head at a minimum before you truly become established and stabilized. 

A terms sheet will tell a pro whether you know what you're talking about and give them a structure of the deal you propose, but it won't establish credibility with respect to your financial ability to pull off the deal.

I invest out of state in Pittsburgh from DC and self-manage everything, but it's taken me years to establish the right contacts, develop seamless processes etc. that allow me to handle everything remotely with confidence.

Specifically, some of the deals I'm considering come from established turnkey companies (very reputable in these forums) that have been around for a long time and they claim very long tenancy terms. 

Trusting a GC can work if you thoroughly vet them, use a detailed contract with clear milestones, and establish systems for accountability.

In your opinion, what is the most effective way to establish an LLC?
