I always follow-up with my agent through email with a recap of the conversation to make sure I understand and prefer that to be our primary means of communication since it is tracked and recorded. 

I keep hearing that in order to learn faster and make sure I don't make the same mistakes that a mentor is vital or at least preferred.

I would prefer to work direct with the builders 

I would agree with Jon, after looking at the markets you prefer, you will then be able to look at properties and say "yay" or "nay" to them.

I have an opportunity in my preferred market for an off market deal with a historic home that has been converted into a 4 plex.

There are some that have a higher pricing adjustment if you close as an individual when purchasing a cashflowing rental as most prefer LLC vesting.  

Personally, Montgomery County is where I prefer due to the lower taxes, but the prices are higher as well.

So it is possible any way you go, just what you prefer!

Preferably we would like to structure this so that reduces or eliminates the tax liability.

You'll need his input for rehab expenses anyway, and since this is a rental your personal preferences for features in a home really aren't that critical.
