@Otis Clayton To partner in real estate effectively, establish a clear structure like an LLC for liability protection or a Joint Venture for single projects.

You should research it and establish your own opinions but as a new investor it's a lot of work.

Does anyone have or know where to find a reliable basic purchase agreement when the price has been established?

Eliminate debt, establish a budget, and save.

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...   

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. 

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

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.
