I self-managed all for 17 years, then 1031 consolidated half and left the seller's PM in place. 

So, in order to do this, you’ll need two things:1) accurate and consolIdated accounting with all of the details entered correctly.

Each building were managed by different PMs, I consolidated them under one PM now.  

After 5 years of this I am going to auction most my properties and keep/ pay off the best ones,So.. use leverage to grow, then consolidate to retire.

Timber is a shell of itself with all the big mills closing and big timber holdings consolidating.

This provides us with a consolidated platform for tracking tasks and communicating with team members.

I hope letting them stay doesn’t come back to bite me as prices continue to increase but I have another lease ending April 1st and will try a consolidation 1031. 

What are your thoughts on moving the old 401k to my current 401k plan with my current employer to consolidate both plans?

This typically all passes through and consolidates on your 1040.

So ratcheting up several times with the 1031 from one to several properties can give you quite a bit of exponential growth.But what's really interesting to me now is the consolidation and globalization of the national real estate market  in the US.
