If you're going the DIY route for OOS investing (vs turnkey) then you're spot on - the people you choose to work with will be the most important, and most difficult, aspect of your plan.

Do you have a "team" of people that will handle the various specialized aspects of a house flipping business (Realtors, CPA's, attorneys, contractors/tradesmen, title companies, lenders, etc.)? 

Advice/opinions on any aspect of this post are greatly appreciated!

One of the most important aspects of development was doing research on the land and knowing what can be done with it and what obstacles you will run into that will need to be worked through.

And perhaps the most overlooked aspect of real estate investing is that time is the greatest ally of the real estate investor. 

As an attorney, I represented developers, REITs, multi-national corporations, and local governments in all aspects of real estate including asset acquisition, development, leasing, and disposition.

Many of the statistical/econometric tools I know like the back of my hand are (claimed to be) used regularly in aspects of decision making in real estate.
