Small multifamily portfolio to large multifamily portfolio

[Steven Barr]

Just starting out here and looking for veteran investor input... Trying to be forward thinking on this strategy

We are considering BRRRRing our way into a $10-20 million portfolio of 2-4 plex properties over the next few years. Maybe that's somewhere between 25 and 50 houses. 

From there, we would like to sell the entire portfolio so we could perform a 1031 exchange and consolidate into an apartment complex. We will then stay in the apartment space. Or at least that is the plan for now... 

Is it going to be possible to sell a portfolio of that size to an individual if the properties are spread out across an entire state? Would a hedge fund purchase? What if all the properties are in LLCs?
